The outcome of autologous chondrocyte transplantation treatment of cartilage lesions in the knee.

Recent results of the clinical outcome of autologous chondrocyte transplantation (ACT) treatment in a group of 28 patients with focal femoral condyle cartilage lesions revealed a correlation trend with the quality of the in vitro cell culture matrix-protein synthesis. No impact of the patients’ age and chondrocyte cryopreservation prior to implantation was observed. Further studies are needed to confirm the preliminary results.
