Overview



We are a medical technology company and innovator in the orthopedic industry
since our founding in 2004. In particular, we believe that we are a leader in
the development, manufacturing, and sales of patient-specific products and
instrumentation that are individually sized and shaped to fit each patient's
unique knee and hip anatomy. The worldwide market for total knee and hip
replacement products is approximately $17 billion annually. In the U.S. elective
total joint procedures are shifting from the hospital to outpatient facilities
and ambulatory surgery centers ("ASCs"). We believe that approximately 50% of
all primary hip and knee procedures will be performed in ASCs within the next
five years.

A key driver in the outpatient shift of orthopedic procedures is the ongoing
changes by the Centers for Medicare & Medicaid Services ("CMS"). In recent
years, CMS removed key musculoskeletal services from the inpatient-only list,
including total knee arthroplasty in 2018 and total hip arthroplasty in 2020.
CMS also continues to expand the ASCs covered procedure list, including total
knee arthroplasty in 2020 and total hip arthroplasty in 2021.
As healthcare costs rise, governments and government agencies, including CMS,
are looking to reduce their healthcare expenditures markedly through
reimbursement reductions and cost-shifting to patients.

On January 6, 2022, we announced the launch of our new Image-to-Implant®
Platinum Services? Program, a premium service offering for the U.S. market. New
to orthopedics, this program addresses the rapidly evolving demands of the
healthcare marketplace where generic products are being commoditized and
patients are increasingly willing to pay a premium for deluxe services. As of
September 1, 2022, U.S. medical facility customers are only able to obtain our
fully personalized iTotal Identity knee system through participation in our
Image-to-Implant Platinum Services? Program.

Both Medicare and most commercial payors permit patients to pay out-of-pocket
for non-covered, deluxe services. Through the Image-to-Implant® Platinum
Services? Program, Conformis is bringing this approach to orthopedics by
enabling participating medical facilities to establish and offer patients an
out-of-pocket services upgrade to obtain the Company's fully personalized iTotal
Identity™ knee system. Combined with our new Made-to-Measure Identity Imprint™
knee system, we believe that we now address multiple market segments within knee
arthroplasty:

•the Identity Imprint™ knee system provides a data-informed high-quality knee
implant system that provides a level of personalization through its
patient-specific instruments ("PSI") and proprietary algorithms for pre-surgical
planning, but is only available in pre-designed standard sizes, all at a price
comparable to standard off-the-shelf options; and

•the Image-to-Implant® Platinum Services? Program gives patients in the United
States the opportunity to upgrade to a fully-personalized iTotal Identity™ knee
implant system by paying an incremental deluxe services fee.

As of December 31, 2022, we had sold a total of more than 149,000 knee implants,
including more than 123,000 total knee implants and 26,000 partial knee
implants. In multiple clinical studies, iTotal CR, our cruciate-retaining total
knee replacement implant, demonstrated superior clinical outcomes, including
with respect to function, kinematics and objective functional measures, and
greater patient satisfaction compared to those of standard, or off-the-shelf,
implants that it was tested against. On August 16, 2021, the first procedure was
performed using the Imprint knee replacement system. Imprint, available in both
cruciate retaining ("CR") and posterior stabilized ("PS") implants, utilizes a
proprietary algorithm to select the appropriate implant size from 12 standard
sizes that most closely meet the geometric and anatomic requirements of the
patient's knee based on the individual's CT scan. As with our personalized
iTotal knee product line, Imprint uses our sterile Surgery-in-a-Box delivery
system, which we believe provides ASCs and hospitals with greater procedural
efficiency and improved sterilization cost savings over comparable systems. With
the interest in our Imprint system from ASC customers, we have prioritized
applying our porous-coated technology to the Imprint system which will be our
first cementless TKA product offering. We are targeting a limited commercial
launch of the porous-coated technology in the second half of 2023, however the
launch may be delayed to the first half of 2024 due to regulatory or technical
challenges.

On November 11, 2019, we entered full commercial launch of the Conformis
personalized hip system, now branded as Cordera Rx. Since the launch of the
personalized hip system, we have introduced multiple product line extensions
including Cordera Standard, Cordera Pro and Cordera Match. In November 2022, we
completed the first procedure using our Actera™ Hip System, a second hip stem
within our hip portfolio. The system, designed for hip reconstruction, uses the
cutting-edge tri-taper stem design, and features a range of sizes and angles
derived from our data analytics. This cementless hip stem component features a
proximally coated titanium spray with a
                                       30
--------------------------------------------------------------------------------

hydroxyapatite layer to encourage initial and long-term fixation. We believe
that the system's tri-taper stem design will enable surgeons to treat a broader
range of patient anatomies and the shorter length options offer easier access to
the femur while maintaining the fixation and integrity required for long term
success of the implant. For the initial limited launch, the Actera™ Hip System
will feature a range of standard sizes in both stem and cup components. We plan
to launch future Actera™ line extensions that will offer additional
personalization options for surgeons to choose what best fits their patients,
even for complex anatomies. The new system is currently rolling out to select
sites across the U.S., and we currently anticipate the commercial launch to
occur in mid-2023.

All of our currently marketed knee and hip replacement products and related
design software have been cleared by the U.S. Food and Drug Administration (the
"FDA") under the premarket notification process of Section 510(k) of the federal
Food, Drug, and Cosmetic Act (the "FDCA"). We have received CE Certificates of
Conformity allowing us to affix the CE Mark.

We market our products and services to orthopedic surgeons, hospitals, and other
medical facilities, and patients. We use direct sales representatives,
independent sales representatives and distributors to market and sell our
products in the United States, Germany, the United Kingdom, Austria, Ireland,
Switzerland, Spain, Portugal, the Netherlands, Belgium, the Dutch Antilles,
Brazil, Suriname, Australia, the United Arab Emirates, the Sultanate of Oman,
Italy, Poland and other markets.

We were incorporated in Delaware and commenced operations in 2004.

COVID-19 Pandemic Update



In December 2019, a human infection originating in China was traced to a novel
strain of coronavirus. The virus subsequently spread to other parts of the
world, including the United States and Europe, and caused unprecedented
disruptions in the global economy as efforts to contain the spread of the virus
intensified. In March 2020, the World Health Organization declared this
coronavirus outbreak (COVID-19) to be a pandemic. We experienced significantly
decreased demand for our products during the pandemic as healthcare providers
and individuals de-prioritized and deferred medical procedures deemed to be
elective, such as joint replacement procedures, which had a significant negative
effect on our revenue. In the third and fourth quarters of 2021, the Company
experienced higher levels of deferred and rescheduled knee and hip procedures as
a result of the surge in COVID-19 cases associated with the Delta and Omicron
variants. During the first quarter of 2022, United States case counts peaked in
January and then trended downward for the remainder of the year. The future
progression of the pandemic remains uncertain.

Components of our results of operations

The following is a description of factors that may influence our results of operations, including significant trends and challenges that we believe are important to an understanding of our business and results of operations.

Revenue



Our product revenue is generated from sales to hospitals and other medical
facilities that are served through a direct sales force, independent sales
representatives and distributors in the United States, Germany, the United
Kingdom, Switzerland, Australia, and other markets. In order for surgeons to use
our products, the medical facilities where these surgeons treat patients
typically require us to enter into pricing agreements. The process of
negotiating a pricing agreement can be lengthy and time-consuming, requiring
extensive management time and may not be successful.

Revenue from sales of our products fluctuates principally based on the selling
price of the joint replacement product, as the sales price of our products
varies among hospitals and other medical facilities. In addition, our product
revenue may fluctuate based on the product sales mix and mix of sales by
geography. Our product revenue from international sales can be significantly
impacted by fluctuations in foreign currency exchange rates, as our sales are
denominated in the local currency in the countries in which we sell our
products. We expect our product revenue to fluctuate from quarter-to-quarter due
to a variety of factors, including seasonality, as we have historically
experienced lower sales in the summer months and higher sales around year-end,
the timing of the introduction of our new products, if any, and the impact of
the buying patterns and implant volumes of medical facilities.

                                       31
--------------------------------------------------------------------------------

Royalty and licensing revenue for the three months ended March 31, 2022 includes
revenue of $0.5 million generated from our license agreement (the "License
Agreement") with Paragon 28. Ongoing royalty revenue is generated from our
license agreement (the "MicroPort License Agreement") with MicroPort Orthopedics
Inc., a wholly owned subsidiary of MicroPort Scientific Corporation, or
collectively, MicroPort. The MicroPort License Agreement will expire upon the
expiration of the last to expire of our patents and patent applications licensed
to MicroPort, which currently is expected to occur in 2031.


We provide certain information regarding our financial results or projected
financial results on a non-GAAP "constant currency basis." This information
estimates the impact of changes in foreign currency rates on the translation of
our current or projected future period financial results as compared to the
applicable comparable period. This impact is derived by taking the adjusted
current or projected local currency results and translating them into U.S.
dollars based upon the foreign currency exchange rates for the applicable
comparable period. It does not include any other effect of changes in foreign
currency rates on our results or business. Non-GAAP information is not a
substitute for, and is not superior to, information presented on a GAAP basis.


This non-GAAP financial measure may be different from non-GAAP financial
measures used by other companies, limiting its usefulness for comparison
purposes. Moreover, presentation of revenue on a constant currency basis is
provided for year-over-year comparison purposes, and investors should be
cautioned that the effect of changing foreign currency exchange rates has an
actual effect on our operating results. We consider the use of a period over
period revenue comparison on a constant currency basis to be helpful to
investors, as it provides a revenue growth measure free of positive or negative
volatility due to currency fluctuations.


Cost of revenue




We produce our computer aided designs, or CAD, in-house and in India and use
them to direct most of our product manufacturing efforts. We manufacture all of
our patient-specific instruments, or iJigs, tibial trays used in our total knee
implants, and polyethylene tibia tray inserts for our iTotal CR and our iTotal
PS product, in our facility in Wilmington, Massachusetts. We polish our femoral
implants used in our total and partial knee products in our facility in
Wallingford, Connecticut. Starting in 2019, we began to manufacture the lateral
partial tibial tray components in our facility in Wilmington, Massachusetts. We
outsource the production of the remainder of the partial knee tibial components,
femoral castings, and other knee and hip components to third-party suppliers.
Our suppliers make our personalized implant components using the CAD designs we
supply. Cost of revenue consists primarily of costs of raw materials,
manufacturing personnel, outsourced CAD labor, manufacturing supplies, inbound
freight, manufacturing overhead, and depreciation expense.


We calculate gross margin as revenue less cost of revenue divided by revenue.
Our gross margin has been and will continue to be affected by a variety of
factors, including primarily volume of units produced, mix of product components
manufactured by us versus sourced from third parties, our average selling price,
foreign exchange rates, the geographic mix of sales, product sales mix,
manufacturing efficiencies, raw material costs, the number of cancelled sales
orders resulting in wasted implants, and royalty revenue.

We expect our gross margin from the sale of our products, which excludes royalty
and licensing revenue, to expand over time to the extent we are successful in
reducing our manufacturing costs per unit, increasing our manufacturing
efficiency, and increasing sales volume through the launch of Identity Imprint™
and our Image-to-Implant® Platinum Services? Program. We believe that areas of
opportunity to expand our gross margin in the future, if and as the volume of
our product sales increases, include the following:

•absorbing overhead costs across a larger volume of product sales;
•increased sales mix of our higher margin Identity ImprintTM product and an
increased selling price as a result of our Image-to-Implant® Platinum Services?
Program;
•obtaining more favorable pricing for the materials used in the manufacture of
our products;
•obtaining more favorable pricing of certain components of our products
manufactured for us by third parties;
•increasing the proportion of our CAD design activities that is performed
in-house at our India facility;
•developing new versions of our software used in the design of our joint
replacement implants, which we believe will reduce costs associated with the
design process; and
•improving the efficiency of our internal manufacturing processes.
                                       32
--------------------------------------------------------------------------------

We also continue to explore other opportunities to reduce our manufacturing costs. However, these and the above opportunities may not be realized. In addition, our gross margin may fluctuate from period to period.

Operating expenses



Our operating expenses consist of sales and marketing, research and development
and general and administrative expenses. Personnel costs are the most
significant component of operating expenses and consist of salaries, benefits,
stock-based compensation, and sales commissions.

Sales and marketing.  Sales and marketing expense consists primarily of
personnel costs, including salary, employee benefits and stock-based
compensation for personnel employed in sales, marketing, customer service,
medical education and training, as well as investments in surgeon training
programs, industry events and other promotional activities. In addition, our
sales and marketing expense includes sales commissions and bonuses, generally
based on a percentage of sales, to our sales managers, direct sales
representatives and independent sales representatives. Recruiting, training and
retaining productive sales representatives and educating surgeons about the
benefits of our products are required to generate and grow revenue. We expect
sales and marketing expense to decrease in 2023 as part of our cost reduction
plans. Our sales and marketing expense may fluctuate from period to period due
to the seasonality of our revenue and the timing and extent of our expenses.

Research and development.  Research and development expense consists primarily
of personnel costs, including salary, employee benefits and stock-based
compensation for personnel employed in research and development, regulatory and
clinical areas. Research and development expense also includes costs associated
with product design, product refinement and improvement efforts before and after
receipt of regulatory clearance, development of prototypes, testing, clinical
study programs and regulatory activities, contractors and consultants, and
equipment and software to support our development. As our revenue increases, we
will also incur additional expense for revenue share payments to our past and
present scientific advisory board members, including one of our past directors.
We expect research and development expense to decrease in 2023 as part of our
cost reduction plans.

General and administrative.  General and administrative expense consists
primarily of personnel costs, including salary, employee benefits and
stock-based compensation for our administrative personnel that support our
general operations, including executive management, general legal and
intellectual property, finance and accounting, information technology and human
resources personnel. General and administrative expense also includes outside
legal costs associated with intellectual property and general legal matters,
financial audit fees, insurance, fees for other consulting services,
depreciation expense, long-lived asset impairment charges, freight, facilities
expense, allocation of manufacturing training costs, and severance expense. We
expect our general and administrative expense to decrease in 2023 primarily due
to lower litigation and other expenses associated with our cost reduction plans.
Our general and administrative expense may fluctuate from period to period due
to the timing and extent of the expenses.

Total other (expenses) income, net



Total other income (expenses), net consists primarily of interest expense and
amortization of debt discount associated with our term loans outstanding during
the year, gain on forgiveness of PPP loan, income related to the development
agreement with Stryker, and gains (losses) from foreign currency transactions.
The effect of exchange rates on our foreign currency-denominated asset and
liability balances are recorded as foreign currency translation adjustments in
the consolidated statements of comprehensive loss.

Income tax provision



Income tax provision consists primarily of a provision for income taxes in
foreign jurisdictions in which we conduct business. We maintain a full valuation
allowance for deferred tax assets including net operating loss carryforwards and
research and development credits and other tax credits.

Product revenue.  Product revenue was $12.7 million for the three months ended
March 31, 2023 compared to $14.9 million for the three months ended March 31,
2022, a decrease of $2.2 million or 15%. The decrease in product revenue was
primarily due to declines in U.S. knee orders following our business model
transition and manufacturing/supply chain challenges.

by geography expressed as U.S. dollar amounts, percentage of product revenue and
year-over-year change (in thousands):

Product revenue in the United States was generated through our direct sales
force and independent sales representatives. The percentage of product revenue
generated in the United States was 83% for the three months ended March 31, 2023
compared to 85% for the three months ended March 31, 2022.

The United States product revenue decreased $2.1 million to $10.6 million or 17%
year over year. The decrease in product revenue was primarily due to declines in
U.S. knee orders following our business model transition and
manufacturing/supply chain challenges. Following the September 1, 2022
transition to the new business model, we have seen a reduction in our orders as
existing customers migrate to the new product and service offering.
Additionally, some of our existing customers have chosen not to offer our fully
personalized iTotal Identity product given it will require an out-of-pocket
patient pay upgrade and some have chosen not to order Identity Imprint given it
is not a fully personalized knee system. Germany product revenue decreased $0.4
million to $0.8 million, or 30% year over year on a reported basis and 26% on a
constant currency basis. We believe the decline was primarily due to continued
reimbursement headwinds from Medizinischer Dienst der Krankenversicherung
("MDK"), operational disruptions, and foreign currency exchange rates. Rest of
World product
                                       34
--------------------------------------------------------------------------------

revenue increased $0.3 million to $1.3 million, or 31% year-over-year on a
reported basis and 39% on a constant currency basis. The increase is primarily
due to an increase in elective surgeries in the UK which were lower in the prior
period as a result of the COVID-19 pandemic, and growth in Australia.

Royalty and licensing revenue. Royalty and licensing revenue was $0.1 million
for the three months ended March 31, 2023 compared to $0.7 million for the three
months ended March 31, 2022, a decrease of $0.5 million or 78%. The decrease in
royalty and licensing revenue was driven by $0.5 million in revenue recognized
under the License Agreement with Paragon 28 in the prior period.

Cost of revenue, gross profit and gross margin.  Cost of revenue was $7.7
million for the three months ended March 31, 2023 compared to $9.8 million for
the three months ended March 31, 2022, a decrease of $2.1 million, or 21%. Gross
profit was $5.1 million for the three months ended March 31, 2023 compared to
$5.7 million for the three months ended March 31, 2022, a decrease of $0.6
million or 11%. Gross margin increased 290 basis points to 40% for the three
months ended March 31, 2023 from 37% for the three months ended March 31, 2022.
The increase in gross margin was driven primarily by higher selling prices on
our fully personalized knees due to our Platinum Services? Program, volume
transition to our lower cost Imprint™ knee system, and decreased cancelled case
inventory expense partially offset by increased labor and material costs and
lower manufacturing volumes.

Sales and marketing.  Sales and marketing expense was $5.1 million for the three
months ended March 31, 2023 compared to $6.7 million for the three months ended
March 31, 2022, a decrease of $1.6 million or 24%. The decrease was due
primarily to lower tradeshow expenses of $0.5 million, commission expense of
$0.6 million, personnel costs of $0.4 million, and other expense of $0.1
million. Sales and marketing expense decreased as a percentage of total revenue
to 39% for the three months ended March 31, 2023 compared to 43% for the three
months ended March 31, 2022.

Research and development.  Research and development expense was $2.5 million for
the three months ended March 31, 2023 compared to $4.5 million for the three
months ended March 31, 2022, a decrease of $2.0 million, or 45%. The decrease
was due primarily to a reduction in project related expenses of $0.7 million,
personnel costs of $1.0 million, and revenue share expense of $0.3 million.
Research and development expense decreased as a percentage of total revenue to
19% for the three months ended March 31, 2023 compared to 29% for the three
months ended March 31, 2022.

General and administrative.  General and administrative expense was $7.0 million
for the three months ended March 31, 2023 compared to $9.3 million for the three
months ended March 31, 2022, a decrease of $2.3 million, or 25%. The decrease
was primarily due to a decrease in litigation expense of $1.1 million,
professional and outside services of $0.5 million, shipping costs of $0.3
million, personnel costs of $0.2 million, and other costs of $0.2 million.
General and administrative expense decreased as a percentage of total revenue to
55% for the three months ended March 31, 2023 from 60% for the three months
ended March 31, 2022.

Total other (expenses) income, net.  Other (expenses) income, net was $0.2
million of other expenses for the three months ended March 31, 2023 compared to
$1.3 million of other expenses for the three months ended March 31, 2022, a
change of $1.1 million, or 87%. The change was primarily due to an increase in
foreign currency exchange transaction income of $1.3 million, partially offset
by higher interest expense of $0.2 million.

Income taxes. Income tax provision was $(18,000) and $34,000 for the three months ended March 31, 2023 and 2022, respectively. We continue to generate losses for U.S. federal and state tax purposes and have net operating loss carryforwards creating a deferred tax asset. We maintain a full valuation allowance for deferred tax assets.

Liquidity, capital resources and plan of operations

Reverse Stock Split



On October 26, 2022, our Board of Directors approved a 1-for-25 reverse stock
split of our Common Stock ("Reverse Stock Split"), which was implemented in
November 2022. As a result of the Reverse Stock Split, each of the holders of
our Common Stock received one (1) new share of Common Stock for every
twenty-five (25) shares such shareholder held immediately prior. Fractional
shares as a result of the Reverse Stock Split were paid in cash. The Reverse
Stock Split also affected the Company's outstanding stock options and warrants
and resulted in the shares underlying such instruments being reduced and the
exercise price being increased proportionately to the Reverse Stock Split ratio.

All share and per share information has been retroactively adjusted to give
effect to the Reverse Stock Split for all periods presented, unless otherwise
indicated. The total number of our authorized shares of preferred stock was not
affected by the foregoing. However, the total number of our authorized common
stock was decreased to 20,000,000 after giving effect to the Reverse Stock
Split. In connection with the Reverse Stock Split, there was no change in the
par value per share of $0.00001.

Sources of liquidity and funding requirements



From our inception in June 2004 through the three months ended March 31, 2023,
we have financed our operations primarily through private placements of
preferred stock, our initial public offering in 2015, other equity financings,
debt and convertible debt financings, equipment purchase loans, patent
licensing, and product revenue beginning in 2007. We have not yet attained
profitability and continue to incur operating losses and negative operating cash
flows. As of March 31, 2023, we had an accumulated deficit of $590.9 million.

We expect to incur substantial expenditures in the foreseeable future in connection with the following:



•expansion of our sales and marketing efforts, including the expanded
advertising of our Platinum Services? Program;
•expansion of our manufacturing capacity;
•funding research and development activities related to new and existing
products, including our porous-coated technology for the Imprint system and
Actera™ line extensions;
•pursuing and maintaining appropriate regulatory clearances and approvals for
our existing products and any new products that we may develop; and
•enforcing our intellectual property rights and pursuing our claims against
Aetna.

We anticipate that our principal sources of funds in the future will be revenue
generated from the sales of our products, potential future capital raises
through the issuance of equity or other securities, available sales of shares
under the Sales Agreement, or potential debt financings, and revenues that we
may generate in connection with licensing our intellectual property.
Additionally, in order for us to meet our long-term operating plan, revenue
growth, gross margin improvements and leveraging operating expenses will be
necessary to reduce cash used in operations. We will need to generate
significant additional revenue to achieve and maintain profitability, and even
if we achieve profitability, we cannot be sure that we will remain profitable
for any substantial period of time. It is also possible that we may allocate
significant amounts of capital toward products or technologies for which market
demand is lower than anticipated and, as a result, abandon such efforts. If we
are unable to obtain adequate financing or financing on terms satisfactory to us
when we require it, or if we expend capital on projects that are not successful,
our ability to continue to support our business growth and to respond to
business challenges could be significantly limited, and we may even have to
scale back our operations. Our failure to become and remain profitable could
impair our ability to raise capital, expand our business, maintain our research
and development efforts or continue to fund our operations.

On March 23, 2020, we filed a shelf registration statement on Form S-3 (the
"Shelf Registration Statement"), which was declared effective by the SEC on
August 5, 2020. Under the Shelf Registration Statement, we are permitted to sell
from time to time up to $200 million of common stock, preferred stock, debt
securities, warrants, or units comprised of any combination of these securities,
for our own account in one or more offerings. The Shelf Registration Statement
is intended to provide us flexibility to conduct sales of our registered
securities, subject to market conditions and our future capital needs.
                                       36
--------------------------------------------------------------------------------


On August 5, 2020, we filed with the SEC a prospectus supplement, for the sale
and issuance of up to $25 million of our common stock and entered into an ATM
issuance sales agreement (the "Sales Agreement"), with Cowen and Company, LLC
("Cowen"), pursuant to which we may offer and sell shares of the our common
stock to or through Cowen, acting as agent and/or principal, from time to time
in an "at-the-market" offering as defined in Rule 415 promulgated under the
Securities Act of 1933, as amended, including without limitation sales made by
means of ordinary brokers' transactions on the Nasdaq Capital Market or
otherwise at market prices prevailing at the time of sale, in block
transactions, or as otherwise directed by us. Under the Sales Agreement, Cowen
will use commercially reasonable efforts to sell the Common Stock from time to
time, based upon instructions from us (including any price, time or size limits
or other customary parameters or conditions we may impose). We will pay Cowen a
commission of up to 3.0% of the gross sales proceeds of any Common Stock sold
through Cowen under the Sales Agreement, and we have provided Cowen with
customary indemnification rights. Any shares of Common Stock offered pursuant to
the Sales Agreement will be offered and sold pursuant to the Shelf Registration
Statement. We are not obligated to make any sales of Common Stock under the
Sales Agreement. The offering of shares of Common Stock pursuant to the Sales
Agreement will terminate upon the earlier of (i) the sale of all Common Stock
subject to the Sales Agreement or (ii) termination of the Sales Agreement in
accordance with its terms. As of the date thereof, we have not sold any shares
under the Sales Agreement.

On September 23, 2020, we and a healthcare-focused institutional investor
entered into a subscription agreement the "Subscription Agreement," pursuant to
which we sold (i) 340,483 shares of its common stock and accompanying warrants
to purchase up to 340,483 shares of common stock and (ii) pre-funded warrants to
purchase up to 379,718 shares of common stock and accompanying warrants to
purchase up to 379,718 shares of common stock in a registered direct offering
(adjusted for the 1-for-25 reverse stock split) for gross proceeds of
approximately $17.3 million. The common stock (or one pre-funded warrants in
lieu thereof) and accompanying warrants were sold as units, each consisting of
one share (or one pre-funded warrant to purchase one share of common stock in
lieu thereof) and one warrant to purchase one share of common stock, at an
offering price of $23.95 per unit. The net proceeds to us from the offering,
after deducting the placement agent's fees and other estimated offering expenses
payable by us, was approximately $15.9 million.

The pre-funded warrants became exercisable immediately upon issuance, have an
exercise price of $0.0025 per share and were exercisable until all of the
pre-funded warrants were exercised in full. As of March 31, 2021, all pre-funded
warrants were exercised. The warrants became exercisable immediately upon
issuance, have an exercise price of $21.87 per share (adjusted for the 1-for-25
reverse stock split), and will expire five years from the date of issuance. As
of December 31, 2022, approximately 240,000 of these warrants have been
exercised. The pre-funded warrants and the warrants each prohibit the holder
from exercising any portion thereof to the extent that the holder would own more
than 9.99% of the number of shares of common stock outstanding immediately after
exercise. The number of shares issuable upon exercise of the warrants and
pre-funded warrants and the exercise price of the warrants and pre-funded
warrants is adjustable in the event of stock splits, stock dividends,
combinations of shares and similar recapitalization transactions.

On November 22, 2021, we entered into a Credit and Security Agreement (the "New
Credit Agreement") with MidCap Financial Services, LLC ("MidCap Financial
Services"), as servicer for MidCap Financial Trust to refinance the Company's
existing senior secured indebtedness. The New Credit Agreement provides for a
five-year, $21 million secured term loan facility (the "Term Facility"), and
replaces our existing credit facility under the 2019 Secured Loan Agreement,
with Innovatus, as collateral agent and lender, East West Bank and other lenders
party thereto (collectively, the "Lenders"). We used the proceeds from the debt
financings to pay off our existing credit facility under the 2019 Secured Loan
Agreement with the Lenders.

The New Credit Agreement contains customary affirmative and negative covenants,
including limitations on our ability to incur additional debt, grant or permit
additional liens, make investments and acquisitions, merge or consolidate with
others, dispose of assets, pay dividends and distributions, pay subordinated
indebtedness and enter into affiliate transactions. In addition, the New Credit
Agreement contains a minimum liquidity covenant requiring the us to maintain
unrestricted cash and cash equivalents in excess of $4.0 million. The New Credit
Agreement also includes events of default customary for facilities of this type
and upon the occurrence of such events of default, subject to customary cure
rights, all outstanding loans under the Term Facility may be accelerated. As of
March 31, 2023, we were not in breach of covenants under the New Credit
Agreement. For further information regarding the New Credit Agreement see "Note
I-Debt and Notes Payable" in the financial statements and related notes
appearing elsewhere in this Quarterly Report on Form 10-Q.

                                       37
--------------------------------------------------------------------------------

On November 8, 2022 we entered into a Settlement and License Agreement with
Medacta, pursuant to which the parties agreed to terms for resolving the
then-existing patent disputes. In consideration of the licenses, releases,
covenants and other immunities granted by us to Medacta, Medacta was required to
pay us a fee promptly after execution of the Settlement and License Agreement,
which was received in full on December 12, 2022. The agreement provides for the
grant of the licenses, covenants-not-to-sue, releases, and other significant
deliverables upon receipt of the payment from Medacta.

On February 17, 2021, we closed an offering of our common stock under the Shelf
Registration Statement and issued and sold 3,238,095 shares of our common stock
at a public offering price of $26.25 per share (adjusted for the 1-for-25
reverse stock split), for aggregate net proceeds of approximately $79.6 million.
We intend to use the net proceeds of the offering of the shares for general
corporate purposes, which may include research and development costs, sales and
marketing costs, clinical studies, manufacturing development, the acquisition or
licensing of other businesses or technologies, repayment and refinancing of
debt, including our secured term loan facility, working capital and capital
expenditures.

On April 8, 2021, we entered into a License Agreement with Paragon 28, granting
Paragon 28 a non-exclusive license under a subset of our U.S. patents for the
use of patient-specific instruments with off-the-shelf implants. In connection
with this License Agreement, we recognized revenue of $1.0 million during the
quarter ended June 30, 2021 and $0.5 million during the quarter ended March 31,
2022. see "Note B-Summary of Significant Accounting Policies" in the financial
statements and related notes appearing elsewhere in this Quarterly Report on
Form 10-Q.

We may need to engage in additional equity or debt financings to secure
additional funds. We may not be able to obtain additional financing on terms
favorable to us, or at all. To the extent that we raise additional capital
through the future sale of equity or debt, the ownership interest of our
stockholders will be diluted. The terms of these future equity or debt
securities may include liquidation or other preferences that adversely affect
the rights of our existing common stockholders or involve negative covenants
that restrict our ability to take specific actions, such as incurring additional
debt or making capital expenditures.

At March 31, 2023, we had cash and cash equivalents of $37.8 million and $0.5
million in restricted cash allocated to lease deposits. Based on our current
operating plan, we expect to fund our operations, capital expenditure
requirements and debt service over the next twelve months with existing cash and
cash equivalents as of March 31, 2023, anticipated revenue from operations,
revenue that may be generated in connection with licensing intellectual
property, available sales of shares under the Sales Agreement, funds from
additional equity or debt financing. We have based this expectation on
assumptions that may prove to be wrong, such as the revenue that we expect to
generate from the sale of our products, the gross profit we expect to generate
from those revenues, and the fact that we could use our capital resources sooner
than we expect.

Cash flows

The following table sets forth a summary of our cash flows for the periods indicated, as well as the year-over-year change (in thousands):



                                                   Three Months Ended March

Net cash used in operating activities.  Net cash used in operating activities
was $9.8 million for the three months ended March 31, 2023 compared to $17.1
million used in operating activities for the three months ended March 31, 2022,
a decrease in use of $7.3 million. The $7.3 million decrease in net cash used in
operating activities was primarily affected by a decrease in net loss of $6.5
million, a decrease in accounts receivable of $2.3 million, a decrease in
prepaid expense and other assets of $0.2 million, a decrease in royalty and
licensing receivable of $0.4 million, an increase in inventory of $0.1 million,
and a decrease in accounts payable, accrued expenses and other
                                       38
--------------------------------------------------------------------------------

liabilities of $0.5 million. Non-cash reconciling items include decrease in unrealized foreign exchange gain/loss of $1.3 million, a decrease in depreciation expense of $0.2 million and a decrease in stock compensation expense of $0.1 million.



Net cash used in investing activities.  Net cash used in investing activities
was $0.9 million for the three months ended March 31, 2023, and for the three
months ended March 31, 2022 net cash used in investing activities was $0.7
million, an increase of $0.1 million. The increase is due to an increase in
costs related to the acquisition of property, plant, and equipment.

Net cash provided by financing activities. Net cash provided by financing activities was $0.0 million for each of the three months ended March 31, 2023 and 2022.

Contractual obligations and commitments



There have not been any material changes to our contractual obligations and
commitments disclosed in the Management's Discussion and Analysis of Financial
Condition and Results of Operations in our Annual Report filed on Form 10-K for
the year ended December 31, 2022 other than changes in our debt facilities as
disclosed in "Note I-Debt and Notes Payable" in the financial statements and
related notes appearing elsewhere in this Quarterly Report on Form 10-Q.

Revenue share agreements



We are party to revenue share agreements with certain past and present members
of our scientific advisory board under which these advisors agreed to
participate on our scientific advisory board and to assist with the development
of our personalized implant products and related intellectual property. These
agreements provide that we will pay the advisor a specified percentage of our
net revenue, ranging from 0.1% to 1.33%, with respect to our products on which
the advisor made a technical contribution or, in some cases, which we covered by
a claim of one of or patents on which the advisor is a named inventor. The
specific percentage is determined by reference to product classifications set
forth in the agreement and is tiered based on the level of net revenue collected
by us on such product sales. Our payment obligations under these agreements
typically expire a fixed number of years after expiration or termination of the
agreement, but in some cases expire on a product-by-product basis or expiration
of the last to expire of our patents where the advisor is a named inventor that
claims the applicable product.

The aggregate revenue share percentage of net revenue from our currently
marketed knee replacement products, including percentages under revenue share
agreements with all of our scientific advisory board members, ranges, depending
on the particular product, from 0.1% to 0.6%. We incurred aggregate revenue
share expense including all amounts payable under our scientific advisory board
revenue share agreements of $0.3 million during the three months ended March 31,
2023, representing 2.3% of product revenue, and $0.6 million during the three
months ended March 31, 2022, representing 4.0% of product revenue. Revenue share
expense is included in research and development. For further information, see
"Note H-Commitments and Contingencies" to the consolidated financial statements
appearing in this Quarterly Report on Form 10-Q.

Segment information

We have one primary business activity and operate as one reportable segment.

Off-balance sheet arrangements



Through March 31, 2023, we did not have any relationships with unconsolidated
organizations or financial partnerships, such as structured finance or special
purpose entities, which would have been established for the purpose of
facilitating off-balance sheet arrangements or other contractually narrow or
limited purposes.

Critical accounting policies and estimates



We have prepared our consolidated financial statements in conformity with
accounting principles generally accepted in the United States. Our preparation
of these financial statements and related disclosures requires us to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements, and the reported amounts of revenue and expenses
during the reporting periods. We believe the critical accounting policies and
estimates that require the use
                                       39
--------------------------------------------------------------------------------

of significant estimates and judgments in the preparation of our consolidated
financial statements include revenue recognition, inventory valuations,
impairment assessments, and income tax reserves and related allowances. We
evaluate our estimates and judgments on an ongoing basis. Actual results may
differ from these estimates under different assumptions or conditions. Our
critical accounting policies and estimates are more fully described under the
heading "Management's Discussion and Analysis of Financial Condition and Results
of Operations-Critical accounting policies and estimates" in our Annual Report
on Form 10-K for the year ended December 31, 2022.
