Brief Summary
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

Outcome Measures
Primary Outcomes (3)
Kujala score
The Kujala Anterior Knee Pain Scale is a patient reported assessment of patellofemoral disorders that assesses subjective symptoms and functional limitations. The score consists of 13 questions that add up to a total of 100 points. Minimum: 0 (worst), Maximum: 100 (best)
24 months postoperative
Norwich Patellar Instability Score (NPI Score)
The Norwich Patellar Instability Score is a patient reported assessment of patellofemoral instability. The score consists of 19 questions with a special weighting for every question. The results are presented in percent. Range: 0% (best) to 100% (worst)
24 months postoperative
BANFF Score
The Banff Score is a patient reported assessment of patellofemoral disorders that assesses patella instability. The score consists of 23 questions. Minimum: 0 (worst), Maximum: 100 (best)
24 months postoperative
