ACUTE REPAIR OF MPFL (MEDIAL PATELLO FEMORAL LIGAMENT) IN FIRST LATERAL DISLOCATION OF PATELLA



Abstract

Recent literature suggests MPFL is the primary medial restraint in lateral patellar dislocation and supports acute repair in first lateral dislocations.

Objective: To evaluate the results of patients who underwent acute surgical repair of MPFL in our unit.

Materials and Methods: Nine patients with mean age of 25(12–41) were evaluated in a dedicated clinic. The mean follow-up was 15.7 months (6–22). All patients had MRI scan preoperatively and were operated within two weeks of injury. Patients were evaluated clinically and Kujala and Lysholm scores were recorded.

Results: None of these patients had further dislocations of patella and patellar apprehension test was negative on examination. The mean Kujala score was 78(74–100) and mean Lysholm score was 92(85–100). All patients had returned to sporting activities at clinic review. All but one mentioned that they would choose surgical repair if the injury occurred in the other knee.

Conclusion: Our results confirm in selective patients acute repair of MPFL is the ideal treatment to prevent recurrent dislocations and early return to sports.
