Medial Patellofemoral Ligament Reconstruction Using Fascia Lata Allograft Combined with Elmslie-Trillat Tibial Tuberosity Osteotomy for Lateral Patellar Instability

What this Trial Is About

Lateral patellar dislocation often results in injury to the medial patellofemoral ligament MPFL, leading to ongoing instability of the knee. Researchers are evaluating the outcomes of reconstructing the MPFL using a fascia lata allograft with isometry assessment, combined with the Elmslie-Trillat tibial tuberosity osteotomy procedure. This study aims to assess how well this combined surgical approach improves knee stability and function in affected patients. Participants will undergo the MPFL reconstruction with fascia lata allograft, guided by isometry assessment, along with the Elmslie-Trillat tibial tuberosity osteotomy. Any additional patellofemoral lesions found during surgery will also be managed. This is a procedural study focused on this combined surgical treatment without a comparison group. During the study, participants will be monitored at 12 and 24 months after surgery. Researchers will evaluate lateral patella stability using apprehension and lateral luxation tests at both time points. Functional assessments include the International Knee Documentation Committee Questionnaire and the Knee injury and Osteoarthritis Outcome Score, as well as range of motion measurements. These evaluations will help measure the success of the surgery and patient recovery over two years.
