[Displacement of the tibial tuberosity in retropatellar cartilage damage and recurrent patellar dislocation].

In our hospital in the years 1980 till 1986 37 displacements of the tuberositas tibiae were performed in chondropathia patellae and recurrent luxation of the patella. The follow-up examination took into consideration the radiological and clinical findings, the subjective complaints and the ability of going in for sports. These clinical experiences and pressure measurements in the femoro-patellar joint show the best results after the displacement of the tuberositas tibiae according to Blauth. Additionally we recommend an accurate indication for chondropathia patellae and recurrent luxation of the patella and accompanying surgical measures.
