A Prospective Study to Evaluate the Safety and Effectiveness of the Cartiva® Synthetic Cartilage Implant for CMC in the Treatment of First Carpometacarpal Joint Osteoarthritis as Compared to a Ligament Reconstruction Tendon Interposition (LRTI) Comparator

This study will evaluate whether Cartiva is an effective treatment for individuals with
osteoarthritis of the first CMC joint in the hand compared to LRTI.

This is a prospective, multicenter study with one treatment arm. Comparisons will be made to
a performance target defined by subtracting a non-inferiority margin of 0.05 from an expected
standard of care success rate of 0.55. The active treatment arm will receive a Cartiva® SCI
for CMC.

A total of 74 subjects will be enrolled into the pivotal study.

Follow up visits will occur at the following time points after the surgical procedure: 2
week, 6 week, 3 month, 6 month, 1 year, 2 year, 3 year, 4 year and 5 year.

Inclusion Criteria:

- ≥ 22 years of age

- Refractory to conservative non-operative standard of care treatment for first CMC OA
lasting for at least 6 months that requires surgical intervention

- Eaton classification stage II or III OA of the first CMC joint based on X-rays taken
within 6 months of the Operative date and evidence of first CMC joint OA based on
subjective review of associated clinical symptoms

- Be willing and able to return for all study-related follow up procedures

Exclusion Criteria:

- Previous CMC implant, trapeziectomy, or LRTI to the affected joint to be treated

- History of or current diagnosis of rheumatoid arthritis

- OA of the scaphotrapeziotrapezoidal (STT) joint based on radiographic assessment in
the hand to be treated

- Any disease, including uncontrolled diabetes mellitus, which is clinically known to
impact wound healing ability

- Known or suspected allergic reaction to polyvinyl alcohol
