Comparison between a static and a dynamic technique for medial patellofemoral ligament reconstruction.
OBJECTIVE
The purpose of our study was to compare the technical difficulties and the results of the use of two different types of femoral graft fixation for medial patellofemoral ligament reconstruction in patients with patellar luxation.


METHODS
Twenty-four matched pair patients, assigned to two groups of 12 patients each, underwent medial patellofemoral ligament reconstruction using one of two techniques: the adductor magnus rigid and the semitendinosus tendon dynamic femoral fixation. Results were assessed using a scale for activities of daily living before and after surgery.


RESULTS
No statistical difference was detected between the groups despite one case of reluxation in the adductor magnus group. No major complication was observed in either group. Patients in the semitendinosus group felt subjectively better, and a larger number of patients in this group resumed the practice of sports.


CONCLUSIONS
Even in the absence of significant differences, the present results suggest that a more dynamic femoral fixation is more advantageous than a rigid alternative.


METHODS
Level III, therapeutic comparative study.
