[Technique of all arthroscopic autologous chondrocyte implantation (ACI) for the treatment of cartilage defects in the knee]. Oper Orthop Traumatol. 2020 Mar 10;: Authors: Schlumberger M, Schuster P, Bülow HJ, Mayer P, Eichinger M, Immendörfer M, Richter J Abstract OBJECTIVE: All arthroscopic treatment of deep cartilage defects in the knee for reconstruction of the articular surface. INDICATIONS: Focal cartilage defects of the knee (ICRS ≥ grade 3) from a size of 2.5 cm2 and more. CONTRAINDICATIONS: Osteoarthritis (Kellgren-Lawrence > grade 2), osseus defect situation, cartilage lesion of the opposing articular surfaces (ICRS > grade 2), instability, malalignment (>3-4°), inflammatory joint diseases. SURGICAL TECHNIQUE: First procedure (cell harvesting): Treatment of additional pathologies, preparation of the cartilage defect, harvesting of osteochondral cylinders for cell culture. Second procedure (cell implantation): Dry arthroscopy, cleaning and drying of the already prepared defect, implantation of the in situ crosslinking cartilage cell suspension. POSTOPERATIVE MANAGEMENT: First procedure (cell harvesting): Early functional treatment with weight bearing as tolerated. Second procedure (cell implantation): No drains, extension brace for 4 days, then free range of motion, partial weight bearing for 4 weeks in patellofemoral implantation and for 8 weeks in tibiofemo...
