A Post Approval Multicenter 10 Year Follow-up Observational Trial of Marketed Product - MP01 vs. Surgical Standard of Care (SSOC) Used for the Treatment of Joint Surface Lesions of the Knee

A Post Approval Multicenter 10 Year Follow-up Observational Trial of Marketed Product - MP01 vs. Surgical Standard of Care (SSOC) Used for the Treatment of Joint Surface Lesions of the Knee

The purpose of the study is to support market adoption and global market access via collection of long-term effectiveness, safety, and radiographic data. The primary hypothesis is that Marketed Product (MP01) retains its superiority over Surgical Standard of Care (SSOC) at 7 years in term of mean improvement in the overall Knee Injury and Osteoarthritis Outcome Score (KOOS).

This is a post approval, multicenter, prospective, comparative, non blinded 10-year follow-up observational study of Marketed Product - MP01 vs SSOC used for the treatment of joint surface lesions of the knee. Up to 12 sites in the United States (US) and outside of the US (OUS) that participated in the pivotal study "A Prospective Multicenter Open-label Randomized Controlled Trial of Marketed Product - MP01 vs. Surgical Standard of Care (SSOC) for the Treatment of Joint Surface Lesions of the Knee" (Marketed Product - MP01 vs. SSOC) will enroll up to 170 subjects who participated in the pivotal study and were not withdrawn due to the index knee requiring a unicompartmental or total knee arthroplasty. Enrolled subjects will be followed up to an additional 5 years post pivotal study procedure. As randomization was 2:1 in the pivotal study, the expected number of Marketed Product - MP01 and SSOC subjects enrolled into this study are approximately 114 and 56, respectively.

Inclusion Criteria:

1. Participated in the pivotal study.
2. Must be physically and mentally willing and able to comply with the follow-up schedule.
3. Signed and dated the IEC/IRB approved Informed Consent Form and HIPPA (if applicable).

Exclusion Criteria:

1. Withdrawn from the pivotal study due to index knee requiring a unicompartmental or total knee arthroplasty.
2. Chemotherapy in the past 12 months.
3. Participation in other clinical trials involving knee procedures.
4. Vulnerable individual including prisoners (i.e., unable to fully understand all aspects of the study that are relevant to the decision to participate or could be manipulated or unduly influenced as a result of a compromised position, expectation of benefits or fear of retaliatory response).
