Medial Patellofemoral Ligament Reconstruction

Abstract Medial patellofemoral ligament reconstruction (MPFLr) is the most frequent surgical procedure performed in patients with chronic lateral patellar instability (CLPI). Depending on the fixation technique used, there are two types of MPFLr: the static and the dynamic. The current trend is to perform a static MPFLr with an anatomic femoral bone attachment and a patellar bone attachment. However, dynamic MPFLr using the adductor magnus tendon as a pulley could be a good option in children in order to avoid the risk of an injury to the distal femur growth plate with the subsequent risk of developing a deformity of the knee. MPFLr has proven to be a safe, reliable and reproducible technique for the treatment of CLPI. The paramount requirement for a successful MPFLr is the proper patient selection as well as correct presurgical planning and a meticulous surgical technique.
