Medial Patellofemoral Ligament Reconstruction

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Biomechanical Engineering

Background:

• Patellar instability is common in young, active individuals, often involving medial patellofemoral ligament (MPFL) disruption.
• Recurrent dislocations necessitate interventions to restore medial patellar stability.

Purpose of the Study:

• To describe and evaluate the efficacy of MPFL reconstruction for treating recurrent patellar instability.
• To optimize surgical technique for improved outcomes and procedural reproducibility.

Main Methods:

• Diagnostic arthroscopy to assess cartilage.
• Medial patellar approach for allograft fixation to the patella.
• Fluoroscopic confirmation and biotenodesis screw fixation of the graft to the femur.

Main Results:

• MPFL reconstruction demonstrates good clinical outcomes, enhancing patellar stability.
• High patient satisfaction reported, with an 85% return to sport rate.
• Low risk of recurrent subluxation or dislocation (7%).

Conclusions:

• MPFL reconstruction is a reliable procedure for recurrent patellar dislocations.
• Optimized graft fixation and visualization techniques can improve reproducibility and clinical results.
