title: Augmented repair of avulsion-tear type medial patellofemoral ligament injury in acute patellar dislocation.
abstract: This study investigated the results of augmented repair for avulsion-tear type medial patellofemoral ligament (MPFL) injury performed on a total of five knees with initial acute lateral patellar dislocation. Augmented repair was performed using a medial retinaculum slip on all five knees. The average follow-up was 5.9 years. The results were evaluated with the Insall, Aglietti, and Tria grading system. Three knees were classified as excellent, one knee as good, and one knee as fair. The mean Kujala score at follow-up was 97.6 points. Augmented repair of the injured MPFL for avulsion-type MPFL injury may be considered as one good option to prevent subsequent dislocation and subluxation.
