Brief Summary
This study aims to determine the ability of medial patellofemoral ligament (MPFL) repair augmented with Biobrace® to decrease the re-dislocation rate after a primary patellofemoral dislocation. First-time patellofemoral dislocation is a significant problem, and the ramifications of recurrence for patients are substantial. Due to the multifactorial nature of the pathoanatomy of patellofemoral instability, it has been difficult to design trials that will show how interventions could affect the natural history of these young patients. No definitive studies have determined whether the surgical reconstruction of the MPFL in patients with mild to moderate pathoanatomic risk factors will decrease the re-dislocation rate after a first-time dislocation. In addition, to date, no synthetic option has provided both biology and strength for ligament augmentation. This innovation may allow for a minimalist approach to keeping the patella centred in the trochlear groove during the healing phase after a first-time dislocation.
Eligibility Criteria
Inclusion Criteria: * Age 13 - 30 years * First-time lateral patellofemoral dislocation in the previous 7 days * Closed or closing growth plates (confirmed on knee x-rays with no change required for surgical technique) Exclusion Criteria: * History of previous patellofemoral dislocation on the index knee * An osteochondral fracture of the patellofemoral joint that requires surgical repair * Unable to complete computer-based outcome questionnaires * Pregnant at the time of surgery
