Abstract
Objective: The purpose of the study was to evaluate the functional results after medial
patellofemoral ligament (MPFL) reconstruction in patients using auto- and allograft.
Patients and methods: A retrospective study was conducted on 28 patients with recurrent
patellar dislocation, with 13 patients (13 knees) undergoing MPFL reconstruction with hamstring autograft, and 15 patients (16 knees) with reconstruction surgery with allograft. The total group included 13 males and 15 females, with an age range of 15---38 years. The graft-related morbidity was studied and a clinical assessment was performed using the pre- and postoperative Kujala score. Associated complications were reported for each group. All the patients had more than 12 months of follow up.
Results: No recurrent dislocations or graft related complications were reported in either group. The post-operative Kujala subjective knee score was 89.2 in the autograft group, and 92.6 in the allograft group (p > .05). One patient in the allograft group received a revision surgery due to poor positioning of anchors. Another patient in the allograft group had non-displaced patella fracture related to the bone tunnels and another patient had flexion deficit and needed mobilisation under anaesthesia.
Conclusion: There were no significant differences between both groups, and the results were comparable.
