[Autologous chondrocyte implantation for focal cartilage lesions: state of the art in 2007].
Autologous chondrocyte implantation (ACI) is a frequently used procedure for full-thickness cartilage lesions in the knee joint. However, to date, there are just a few prospective, randomized clinical studies and most publications are case series on small and heterogenic cohorts with short-term follow-up. To date, ACI is a surgical treatment option for single traumatic lesions on the distal femur in young active subjects with a recent lesion. Lesion size should be between 3 and 8 cm2, < 6 mm in depth, tidemark preserved without penetration of the subchondral bone. Absolute contraindications for ACI include osteoarthrosis, kissing lesions, lesions size greater than 10 cm2 or deeper than 8 mm, ligament instability, partial or total meniscectomy, axis malalignment > 5. Further studies are mandatory to determine the precise indications to the technique and to show its superiority on the established treatment of chondral lesions.
