Cartilage or Osteochondral Defects in the Knee Up to Moderate Osteoarthritis | Device: Agili-C implant Procedure: SSOC | Not Applicable |
This is a prospective, multicenter, open-label, randomized, and controlled trial of Agili-C™ vs. SSOC for the repair of joint surface lesions.
Follow-up visits will be performed at 2 weeks and at 3, 6, 12, 18 and 24 months post-procedure to evaluate the patient's knee condition and clinical health. The following questionnaires: KOOS, IKDC Knee Examination Form 2000, IKDC Subjective Knee Evaluation , SF-12 Health Survey, Tegner Activity Score will be completed at baseline and at 6, 12, 18 and 24 months. Anterior-Posterior (A/P) and Lateral knee X-rays will be taken at 2 weeks and at 6, 12, 18 and 24 months post procedure. MRI according to specific protocol will be performed at 12 and 24 months.
