[Treatment of deep cartilage defects in the knee with autologous chondrocyte transplantation: a review of 28 cases].

Purpose Of The Study: The knee has little capacity for spontaneous regeneration of deep cartilage defects. In 1999, the French Society of Arthroscopy initiated a multicentric clinical trial on autologous chondrocyte transplantation using the technique described by Brittberg and Peterson. The protocol of this prospective study was validated by the ethics committee and all patients provided the informed consent for participation.
