Brief Summary:
The current study compares the efficacy and safety of the Agili-C implant to Surgical Standard of Care treatment in patients suffering from joint surface lesions of the knee. The patient population is heterogeneous, involving different kinds of joint surface lesions: focal cartilage lesions, osteochondral defects and mild to moderate osteoarthritis, including multiple defects.

Condition or disease Intervention/treatment Phase
Cartilage or Osteochondral Defects in the Knee Up to Moderate Osteoarthritis Device: Agili-C implant Procedure: SSOC Not Applicable

Detailed Description:

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.
