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

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(Marketed Product - MP01 vs. SSOC) will enroll up to 170 subjects who participated in the pivotal study and were not withdrawn due to the index knee requiring a unicompartmental or total knee arthroplasty.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.
