Medial Patellofemoral Ligament Reconstruction

Abstract

Recurrent patellofemoral instability is a common disabling condition especially in young individuals. MPFL is the main stabilizer to lateral patellar displacement and its reconstruction will restore patellofemoral stability. Many techniques had been described to reconstruct MPFL with good results and few complications taking in consideration meticulous surgical technique and careful patient selection. We used hamstring autograft in a double bundle anatomic MPFL reconstruction technique with both ends of the graft fixed to patella through two blind tunnels by anchor and bioabsorbable interference screw fixing the graft through a blind tunnel in the femur at 30 degree flexion.
