Researchers are evaluating two surgical techniques for treating recurrent patellar dislocation, a condition where the kneecap repeatedly slips out of place. This study compares a new dynamic medial patellofemoral ligament (MPFL) reconstruction method developed by Becher, designed to address common complications of the traditional static technique, with the established static MPFL reconstruction method. The goal is to assess how well each method prevents patella instability and improves quality of life. The study involves two groups: one receiving the static MPFL reconstruction using a graft attached to the femoral and patellar bones with tunnels, screws, or anchors, and the other receiving the dynamic reconstruction where part of a hamstring muscle is repositioned to allow the kneecap to adjust dynamically during muscle contraction. Both techniques use the gracilis tendon, and participants undergo surgery followed by monitoring for up to 24 months. Participants will be assessed before surgery, during hospitalization, and at several follow-ups over two years. Researchers will measure knee function, pain levels, muscle strength, gait symmetry, and rates of patella dislocation or revision surgery. The study also tracks hospital stay length, operation time, complications, and quality of life scores. This comprehensive evaluation aims to determine which surgical method offers better outcomes for patients with patellar instability.
