INTRODUCTION: Autologous chondrocyte implantation (ACI) for the treatment of articular cartilage lesions of the knee joint provides successful and durable long-term outcomes. INDICATIONS then sew it, tying the sutures knots on the membrane and not the cartilage, to tension it adequately throughout the entire defect. STEP 7: CHONDROCYTE IMPLANTATION (VIDEO 6): Gently deliver the cells and fill the defect. STEP 8: POSTOPERATIVE CARE: (1) Initiate range-of-motion exercises to enhance chondrocyte regeneration and decrease the likelihood of intra-articular adhesion, (2) protect the graft from loading for 6 to 12 weeks after surgery to prevent graft overload and central degeneration or delamination of the graft, and (3) initiate isometric muscle exercises to regain muscle tone and prevent atrophy. RESULTS: ACI provided durable outcomes in 210 patients followed prospectively for 10 to 17 years after treatment with the first-generation ACI-periosteum technique(6). PITFALLS & CHALLENGES:
