Medial Patellofemoral Ligament Reconstruction in a Revision Setting: Anchor and Interference Screw Fixation

Abstract

Recurrent patellar instability is a common pathology and typically affects younger and more active patients. To prevent complete lateral dislocation of the patella, several osseous and soft-tissue procedures have been previously described, including reconstruction of the medial patellofemoral ligament (MPFL), which has been identified as the primary medial stabilizer of the patella. Several techniques have been reported for reconstruction of the MPFL, sometimes in conjunction with other procedures, with the majority showing success in the treatment and resolution of patellar instability. However, MPFL reconstruction is not free of complications, with previous reports of recurrence of medial patellar instability and patellar fracture after surgery. The objective of this technical note is to describe our preferred technique, comprising anchor as well as interference screw fixation, for reconstruction of the MPFL in a primary or revision setting.
