Patellar Instability Surgery

Patella realignment can be proposed in the case of recurrent dislocations of the patella or osteoarthritis of the lateral part of the femorotibial joint. Patella realignment involves the medial transfer of the anterior tibial tuberosity, a piece of bone located on the anterior side of the tibia in which the patellar tendon inserts. This is combined with cutting arthroscopically the patellar insertion of the vastus lateralis tendon, which helps decrease the lateral pulling forces and realign the patella with the femur.
