Clinical Trial Summary

The purpose of this study is to elucidate surgical techniques for reconstructing MPFL in the treatment of chronic patella instability. The two techniques are conventional technique with the gracillis and screw fixation in the femur which is compared with new technique where the QT tendons and anchor fixation in the femur are used.

It would be investigated which technique provides the best stability with the least postoperative pain from the reconstruction and the lowest frequency of patellar reluxation.
