Revolutionizing Osteoarthritis Treatment

CytexOrtho solves joint pain at the source and preserves joints, rather than replacing them. We exist to level up the quality of life for the millions of people who suffer from chronic joint pain and offer a true, permanent solution to joint damage and/or osteoarthritis (OA).

Young patients aged 18 to 55 years old with cartilage disease are currently without any surgical treatment options that will fully restore their mobility, short of a complete (and temporary) joint replacement. Our revolutionary cartilage restoration implants serve as effective alternatives and will enable orthopedic surgeons to proactively preserve the hip joint for a young market, offering the solution many patients have been waiting for.

*Thomas P. Vail is on the Clinical Advisory Board for CytexOrtho.

The implant is manufactured using a unique combination of part 3D-printing and part 3D-woven textile. The result is an implant that has been engineered to mimic the functionality of healthy joint tissues. The completely biodegradable/bioabsorbable material augments natural tissue regeneration while restoring joint function and mobility. The flexible design and manufacturing allows the CytexOrtho implant to easily be reconfigured for treating other joints such as the knee, ankle, and shoulder. As such, CytexOrtho’s implant technology has true platform potential.

Since our founding, CytexOrtho has won numerous state and federal grants recognizing the novelty of our research and our products’ enormous potential to transform joint care. The co-founders of CytexOrtho, Drs. Guilak, Estes, and Moutos recently won the Kappa Delta Elizabeth Winston Lanier award from the American Academy of Orthopaedic Surgeons (AAOS). This award recognizes research in musculoskeletal disease or injury that's forecasted to have the greatest impact and advancement on patient care. The Kappa Delta awards are one of the highest honors in the field of orthopedic research.

Our surgical implants are past the design phase and animal testing was successful. We are currently in the process of submitting the appropriate materials to the FDA so we can begin clinical trials and move forward to market launch.

The Problem

Distinct Lack of Treatment Options for Young OA Patients

Osteoarthritis isn’t just a painful problem through which people have to suffer, it is also a costly one, and exerts a tremendous burden on the economy. In the U.S. alone, over 32.5 million people suffer from OA, and the direct and indirect costs of OA, such as medical expenditures, lost wages, and quality of life, exceeds more than $136 billion per year. (source)

While the elderly population is the typical age group associated with OA, there are still millions of people between the ages of 18-55 who suffer as well.


While these patients have youth on their side, the damaged cartilage will not heal on its own and will inevitably progress to OA. Unfortunately, they lack effective surgical options other than a total joint replacement. This puts orthopedic surgeons and patients in a bind – the patient either suffers with the disease until they are older, or the joint is replaced at an early age, knowing that a replacement will limit activity level and lifestyle and that it will ultimately get worn down and require another replacement.

There is a Major Treatment Gap in OA Therapy

A compromised hip joint affects a person’s quality of life, but a hip replacement in the young also affects their quality of life. A total hip replacement should not be the only answer to OA. While a total joint replacement is appropriate for older patients, it is not ideal for younger, more active patients. This is because the average implant needs replacing after 15 to 20 years. If a hip is replaced when the patient is in their 40s or 50s, a revision surgery is almost guaranteed a decade or two later. The surgery also is likely to leave a less stable joint the second time around and is prone to more complications than the first one.

We believe these patients and their doctors deserve a better, less invasive alternative, to a total hip replacement.

The Solution

A Biodegradable Implant to Restore Joint Cartilage

CytexOrtho’s novel joint restoration implant is made by bonding a high-performance, highly engineered textile structure with a 3D printed component. The integrated structure is made from biodegradable materials that restore the joint contours while integrating with the surrounding tissues of cartilage and bone.

*Products are in development. This is potential future technology and not approved by the FDA and not commercially available.

These implants are designed to act as a load-bearing surface for immediate movement and mobility of the joint after surgery. This surgery will require no biologic glue, sutures, screws, or other fasteners, and it dissolves over time, leaving only the patient’s own tissues once healed. This leaves open the option for a repeat procedure if necessary down the line, or allows conversion to a total hip replacement once the patient reaches a more appropriate age for such.

*Images are computer generated for demonstration purposes only.

What’s truly exciting about our implants, however, is their versatility. While we're focusing on hip joints for our initial market entry, the CytexOrtho implant can easily be made to match the geometry of the contours in any joint due to the design and flexibility we built into the manufacturing process. This will allow us to translate use of our technology to the treatment of other joints, such as knees, ankles, and shoulders.

CytexOrtho plans to sell our implants to hospitals directly for $5,000 per unit, with an estimated cost of goods of approximately $350 per unit.

*Products are in development. This is potential future technology and not approved by the FDA and not commercially available.

The development of CytexOrtho's implants is being guided by recognized experts in hip surgery, hip preservation, and the clinical evaluation of cartilage repair techniques. This ensures that our products meet the real world needs of the orthopedic community. Our Clinical Advisory Board is comprised of Dr. John Clohisy, Washington University; Dr. Paul Beaulé, University of Ottawa; Dr. Young-Jo Kim, Harvard Medical School; Dr. Thomas Vail, University of California, San Francisco; and Dr. Hollis Potter, Hospital for Special Surgery.

The Market

Untapped Market Potential

Overall, the younger patient population, with either hip-related OA or prearthritic disease, represents a growing and tremendous clinical need and is the initial target market for CytexOrtho implants.

The total addressable market for CytexOrtho’s novel implants exceeds $4B; however, our initial market entry will be targeting patients affected with prearthritic hip disease that ultimately leads to OA.* One prearthritic disease state that is on the rise is femoral acetabular impingement (FAI) - as many as 25% of men and 10% of women show radiological deformities that make them susceptible to hip disease and OA. While many of these patients were not presenting with chronic pain, the evidence of abnormalities in the general population starts to explain the growing FAI market. This growing interest in FAI disease is clearly evidenced in the number of publications that have steadily grown to over 1500 publications in the medical and scientific literature in the previous year alone.

*Raveendran R, Stiller JL, Alvarez C, Renner JB, Schwartz TA, Arden NK, Jordan JM, Nelson AE. Population-based prevalence of multiple radiographically-defined hip morphologies: the Johnston County Osteoarthritis Project. Osteoarthritis Cartilage. 2018;26(1):54-61


Along with FAI, other conditions such as trauma, osteonecrosis, and joint deformity add to the young patient population in need of alternatives to hip replacement. As a result, patients and surgeons alike are seeking techniques and procedures for joint preservation.

Defining the market further, there are approximately 1 million adults in the U.S. under the age of 65 who have severe hip pain due to arthritis (OA).1 Yet, only 1 out of 5 of these patients will elect to have a hip replacement.2 The current hip replacement market size in the U.S. is valued at $2.3B and is growing at a CAGR of 5.3% between 2021-2028.3 The approximate 50% of these patients who are under 65 years of age plus the 80% of patients who currently do not elect a hip replacement define the potential market opportunity for CytexOrtho’s implant. Assuming only a modest 20% of this patient population can be addressed by CytexOrtho’s technology, the market potential is in excess of $1B US dollars.4

*Products are in development. This is potential future technology and not approved by the FDA and not commercially available.

Beyond these initial entry points, Cytex implants could be used for the restoration of other joints, specifically the knee and ankle, both of which carry significant market potential.

Irregular Use of Proceeds

The Company may change the intended use of proceeds if our officers believe it is in the best interests of the company. The Company has full discretion to alter the use of proceeds set forth above to adhere to the Company’s business plan and liquidity requirements. For example, economic conditions may alter the Company’s general marketing or general working capital requirements. If we raise more than $2.5 million from this offering in combination with other financings between December 6, 2022 and December 6, 2023, we will be required to repay all or a portion of the outstanding balance on our NC Biotechnology Center loan. These payments may not be triggered by this offering so are not reflected in our discussion of Uses of Proceeds. Some of the proceeds from this fundraising event will be used to pay the salaries of the Company’s executives, officers, and directors along with the rest of its employees. The salaries for these positions vary, but currently fall in the range of $50,000 - $150,000 per year. Some of the proceeds may also be used to pay stipends to our Independent Directors. Independent Directors’ stipends are anticipated to be approximately $10,000 per year. As discussed above, we compensate our executive officers and members of our board of directors and have entered into service contracts with these individuals. The Company has been primarily grant funded since its inception. Due to the nature of grant awards, only a very limited amount of these awards may be used to pay staff salaries, as the majority of each award is intended to fund research endeavors. Because of this, the Company is in need of additional capital to support the salaries of all of its staff, which includes some employees who are also executives, officers, and directors. Therefore, some of the proceeds from this fundraising event will be used to pay the salaries of the Company’s executives, officers, and directors along with the rest of its employees. The salaries for these positions vary, but currently fall in the range of $50,000 - $150,000 per year and may be supplemented with an additional annual bonus equaling 10-15% of annual salaries. Some of the proceeds may also be used to pay stipends to our Independent Directors. Independent Directors’ stipends are anticipated to be approximately $10,000 per year. The Company will also use the proceeds of this fundraising event to pay its vendors, some of whom will be paid in excess of $10,000. These vendors may provide research services to support the advancement of the Company’s products towards commercialization, or they may provide other products or services that the Company needs to conduct business, such a lease payments, health insurance for the Company’s staff, intellectual property fees, or fees to StartEngine.

I really want to invest. I would feel a lot more confident investing if I knew I was a candidate for this treatment. What makes someone a good candidate? Can the joint be beyond a certain point of damage where a hip replacement would have to be used? Say for someone in their early forties. If you have a link for this information I have no problem reading through it. thanks!

Congratulation on the $1.2 NIH grant. 1. What FDA indications is CytexOrtho initially seeking? 2. What FDA indications might CytexOrtho eventually seek? 3. Is there an upper age limit to a CytexOrtho patient, and if so, what would that age be (you mention targeting 18-55 yo and an "initial target market)? Will people older than 55 eventually be able to benefit from a CytexOrtho implant? 4. Which will proceed quicker, human studies or studies in dogs and which will come to market first? 5. What is the "life expectancy" of a joint treated with a CytexOrtho implant? Is it a cure, or a bridge to a hip replacement? 6. What does recovery after receiving a CytexOrtho hip implant in humans expect to look like? 7. Can the same hip receive multiple CytexOrtho implants over time? 8. If a patient meets criteria for a hip replacement, when would that patient also be a candidate for a CytexOrtho hip implant and when would that patient not be a candidate for a CytexOrtho hip implant? 9. How would you estimate the ranking and ballpark size of the market potential of the various joints that could benefit from CytexOrtho (ie hips about 40%, knees 30%, shoulders 20%, etc)? 10. How complicated would the procedure be compared to other procedures orthopedists perform? How long to train and become proficient? 11. What does your current roadmap look like (safety trials, efficacy trials, seeking FDA approval, future fundraising, future grant applications, scaling, liquidity event, etc)? 12. Will human trials occur at Duke or somewhere else? 13. Has a cost comparison analysis been done on a CytexOrtho hip implant vs a hip replacement and, if so, how do they compare? Thanks, and congratulations again.

I have the following questions: • Has the Company previously raised any outside capital, e.g., angel investors, friends and family, etc. Or, has the Company been self-funded up to this point in time? • If the Company has raised any outside capital: o from whom (e.g., angels, friends and family, etc.), and o what securities were issued to the investors, e.g., common shares, preferred shares, convertible note, etc.? • When you say “small raise”, how much are you looking to raise (e.g., $250,000, $750,000 or more than $1M)? • How long will that amount last? That is, if you raise $500,000 when will you need to raise more money? • For those investing, what security will they received, e.g., common stock, preferred stock, convertible note, etc.? o If preferred stock, what are the rights of the preferred stock holder? o If common stock, what happens to the common stock holders when the Company raises its first round of venture capital when the VCs will want preferred stock? For example, does the common convert to preferred so that the initial investors are in the same position as the preferred shareholders? • Is there a limit as to a minimum investment or a maximum investment by friends and family at this stage? • Is the Company an LLC, S-Corporation, C-Corporation or some other legal entity? • If an LLC, will you please send us a copy of the LLC Operating Agreement? • Does the Company have written agreements with each founder and each employee and contractor pursuant to which each founder, employee and contractor has assigned to the Company all the intellectual property that he/she developed for or that is related to the Company’s technology and IP? • Have you applied for any patents? If so, how many? • Have any animal testing/studies been done to analyze safety, toxicity, and/or efficacy? If so, what were the results? • Is there a business plan or offering memorandum that you can share that details the Company’s business and business plan? • If you or Brad or any of the other founders employed by or contracting with other companies and if so does CytexOrtho technology relate to the products or technology of these other employers/companies? • Who is the Company using for legal counsel to advise on things like FDA, securities, IP protection, etc.? • Did the technology originate at a University or using University funding, facilities or personnel? If so, does the Company have a license agreement with the University?

At the close of an offering, all investors whose funds have “cleared” by this time will be included in the disbursement. At this time, each investor will receive an email from StartEngine with their Countersigned Subscription Agreement, which will serve as their proof of purchase moving forward.

Please keep in mind that a company can conduct a series of “closes” or withdrawals of funds throughout the duration of the campaign. If you are included in that withdrawal period, you will be emailed your countersigned subscription agreement and proof of purchase immediately following that withdrawal.

StartEngine assists companies in raising capital, and once the offering is closed, we are no longer involved with whether the company chooses to list shares on a secondary market, or what occurs thereafter. Therefore, StartEngine has no control or insight into your investment after the close of the live offering. In addition, we are not permitted to provide financial advice. You may want to contact a financial professional to discuss possible investment outcomes.

For Regulation Crowdfunding, investors are able to cancel their investment at any point throughout the campaign up until 48 hours before the closing of the offering. Note: If the company does a rolling close, they will post an update to their current investors, giving them the opportunity to cancel during this timeframe. If you do not cancel within this 5-day timeframe, your funds will be invested in the company, and you will no longer be able to cancel the investment. If your funds show as ‘Invested’ on your account dashboard, your investment can no longer be canceled.

For Regulation A+, StartEngine allows for a four-hour cancelation period. Once the four-hour window has passed, it is up to each company to set their own cancelation policy. You may find the company’s cancelation policy in the company’s offering circular.

Once your investment is canceled, there is a 10-day clearing period (from the date your investment was submitted). After your funds have cleared the bank, you will receive your refund within 10 business days.

Refunds that are made through ACH payments can take up to 10 business days to clear. Unfortunately, we are at the mercy of the bank, but we will do everything we can to get you your refund as soon as possible. However, every investment needs to go through the clearing process in order to get sent back to the account associated with the investment.

Both Title III (Regulation Crowdfunding) and Title IV (Reg A+) help entrepreneurs crowdfund capital investments from unaccredited and accredited investors. The differences between these regulations are related to the investor limitations, the differing amounts of money companies are permitted to raise, and differing disclosure and filing requirements.

The availability of company information does not indicate that the company has endorsed, supports, or otherwise participates with StartEngine.

None of the information displayed on or downloadable from (the 'Website') represents a recommendation, offer, or solicitation of an offer to buy or sell any security. It also does not constitute an offer to provide investment advice or service. StartEngine does not (1) make any recommendations or otherwise advise on the merits or advisability of a particular investment or transaction, or (2) assist in the determination of fair value of any security or investment, or (3) provide legal, tax, or transactional advisory services.

Investing in private company securities is not suitable for all investors. An investment in private company securities is highly speculative and involves a high degree of risk. It should only be considered a long-term investment. You must be prepared to withstand a total loss of your investment. Private company securities are also highly illiquid, and there is no guarantee that a market will develop for such securities. Each investment also carries its own specific risks, and you should complete your own independent due diligence regarding the investment. This includes obtaining additional information about the company, opinions, financial projections, and legal or other investment advice. Accordingly, investing in private company securities is appropriate only for those investors who can tolerate a high degree of risk and do not require a liquid investment.

StartEngine Marketplace (“SE Marketplace”) is a website operated by StartEngine Primary, LLC (“SE Primary”), a broker-dealer that is registered with the SEC and a member of FINRA and the SIPC. StartEngine Bulletin Board ("SE BB") is a bulletin board platform that advertises interest in shares of private companies that previously executed Reg CF or Reg A offerings. SE BB enables shareholders to communicate interest in potential sales of shares in private companies and investors to discover, review, and potentially invest in private companies. As a bulletin board platform, SE BB provides a venue for investors to access information about private company offerings and connect with potential sellers. SE BB is distinct and separate from StartEngine Secondary (“SE Secondary”), which is an SEC-registered Alternative Trading System (ATS) operated by SE Primary. SE Secondary facilitates the trading of securities by matching orders between buyers and sellers and facilitating executions of trades on the platform. While a security may be displayed on the bulletin board, these securities will be subject to certain restrictions which may prevent the ability to buy and sell these securities in a timely manner, if at all. Even if a security is qualified to be displayed on the bulletin board, there is no guarantee an active trading market for the securities will ever develop, or if developed, be maintained. You should assume that you may not be able to liquidate your investment for some time or be able to pledge these shares as collateral.
