Medial Patellofemoral Ligament Reconstruction with Quadriceps Autograft for Neglected Unreduced Patellar Subluxation: A Case Report

INTRODUCTION: The medial patellofemoral ligament is the primary stabilizer of the patellofemoral joint. Over the past decade, reconstruction has been recommended in adults with patellar instability. However, the reconstruction methods have not been standardized. The best graft and reconstruction methods have not yet been identified METHODS: A 44-year-old female patient with knee unable to flex with pain following trauma. Patient underwent medial patellofemoral ligament reconstruction with quadriceps autograft. Arthroscopy was performed on anterolateral and anteromedial of the patella, obtained elongation and titling of the patella with medial articular surface defect, debridement was conduct. The MPFL reconstruction was done with the superficial quad graft technique, the end of the graft was sutured and measured, drilled the femur on the Schottle point using C-Arm guide according to the graft diameter. The graft is placed in the subvastus space, fixation of the graft with superior to inferior side switches, examined to ensure the stabilisation of the flexion and extension tension and fixated with screw RESULTS: After the operation, the patient is able to perform regular daily activities without any complaints CONCLUSION: This study has found that medial patellofemoral ligament reconstruction using quadriceps autograft leads to an acceptable functional outcome for treating neglected unreduced patellar subluxation
