Abstract
Background
Recurrent dislocation of the patella is a challenging problem due to complex biomechanics of patellar stabilty. Reconstruction of Medial patellofemoral ligament (MPFL) is becoming a common surgical procedure in treating patellar instability.Patella apprehension test, q angle and Insall index are various parameters which helps in deciding the line of treatment..
Material and method
MPFL reconstruction was performed using gracilis graft and fixed on patella by making a loop using two tunnels in 30 patients. The femoral side was fixed with bio screw. Patients were evaluated for pain relief, functional improvement and radiographic analysis The patients were followed on an average mean of 28 (16-40) months Patient function measures included:with subjective criteria of Kujala score and Lysholm score.
Result
The mean preoperative mean Kujala score was 33.93 and Lysholm score was 36.92. The mean postoperative mean Kujala score was 83.22 and Lysholm score was 84.88. No patient had reported with redislocation till date.
Conclusion
There was no episode of recurrent dislocation and range of motion was normal in all cases. This method gives rigid fixation on both sides and provides adequate stability.
