Official Title: Medial Patellofemoral Ligament (MPFL) Reconstruction With or Without Tibial Tubercle Transfer for Recurrent Patellar Instability

Brief Summary: This study aims to compare the clinical outcome of Medial PatelloFemoral Ligament (MPFL) reconstruction with and without tibial tubercle transfer for recurrent patellar dislocation.

Detailed Summary: 70 patients with recurrent patellar instability were randomly assigned to undergo MPFL reconstruction with or without tibial tubercle transfer. Follow-ups were performed at 12 and 24 months postoperatively, and computed tomography (CT) was performed immediately after the operation and at follow-up. The knee function was evaluated preoperatively and at 2 years postoperatively using Lysholm,Tegner and Kujala scales. Redislocation or multiple episodes of patellar instability were considered failures.
