Midterm clinical and functional outcomes after isolated double bundle anatomic MPFL reconstruction in patients with patellofemoral instability

The purpose of this study was to demonstrate midterm outcomes after isolated double bundle anatomic MPFL reconstruction in a young patient cohort. Between 2014 and 2016; 24 knee joints of 23 patients were operated and evaluated in our retrospective study. The time and duration of the patients' complaints, preoperative and postoperative knee range of motion, extent of patellofemoral pain and episodes of lateral patellofemoral instability were evaluated. Functional outcomes were evaluated with Kujala, IKDC, KOOS-QoL and Tegner activity scores. Patellar height was analysed radiographically using the Caton–Deschamps index. Patients were also asked if they were satisfied with the operation. The mean age of the patients during index surgery was 16.7 ± 8.4 years. 87 % of our patients was satisfied with the surgery. The average Kujala score increased from 72 to 96 (p
