Hamstring Versus Quadriceps Tendon Graft for MPFL Reconstruction

This prospective comparative study compared the clinical and radiological outcomes of medial patellofemoral ligament (MPFL) reconstruction using a hamstring tendon graft versus a quadriceps tendon graft in patients with recurrent patellar dislocation. The study included 38 patients with 40 affected knees who underwent MPFL reconstruction using either a hamstring tendon graft or a quadriceps tendon graft, according to the treating surgeon's preference. Patients were prospectively followed in two groups according to the graft used. Clinical outcomes were assessed using the Kujala, International Knee Documentation Committee (IKDC), and Tegner-Lysholm scores. Radiological assessment included patellar tilt angle and congruence angle. Postoperative complications and recurrent patellar instability were also evaluated.
