Evaluation Of Clinical Outcome Of Medial Patellofemoral Ligament Reconstruction In Patients With Recurrent Patellar Instability

BACKGROUNDRecurrent patellar instability is not an uncommon entity with acute patellar dislocation accounting for 2% to 3% of all knee injuries and is the second most common cause of traumatic knee haemarthrosis. Based on recent biomechanical studies, among the medial patellar stabilisers the Medial Patellofemoral Ligament (MPFL) is considered as the primary restraint against lateral dislocation of the patella.MATERIALS AND METHODSThis is an observational study. 25 patients (15 males and 10 females) with recurrent patellar dislocation were operated with MPFL reconstruction with tendon graft and bio screw. Their clinical outcome was measured with respect to pre-op, 3 months post-op and 6 months post-op Kujala score. SPSS software was used for analysis.RESULTSPre-op mean Kujala score was 71.24 and 6 months mean Kujala score was 75.12.CONCLUSIONThis study demonstrates that clinical outcomes are good after isolated MPFL reconstruction, as evidenced by the Kujala score. Study findings correlate well with other previous studies done on MPFL reconstruction for recurrent patellar dislocation.
