Clinical Outcome of the Dynamic Reconstruction of the Medial Patellofemoral Ligament (MPFL)

In a single surgical center, 213 consecutive patients with 221 knees were surgically treated for recurrent lateral patellar dislocation between 07/2010 and 12/2016. All patients obtained dynamic reconstruction of the MPFL with detachment of the gracilis tendon at the pes anserinus while maintaining the proximal origin at the gracilis muscle. Patellar fixation was performed by oblique transpatellar tunnel transfer and tenodesis screw. Follow-up data including Kujala-, BANFF- and Norwich patellar instability score as well as Return-to-Sport and pain level were collected at a minimum follow-up of 2 years
