Background: Patellar instability is common in skeletally immature patients; however, the presence of open physes presents unique challenges to surgical management. Purpose: To (1) assess the safety and efficacy of anatomic medial patellofemoral ligament reconstruction (MPFL-R) in a skeletally immature patient population at short-, mid-, and long-term follow-up and (2) determine the influence of patient factors and surgical and radiographic characteristics on the risk of recurrent instability and clinical outcomes after surgery. Study Design: Case series; Level of evidence, 4. Methods: A retrospective analysis was conducted of the records of skeletally immature patients who underwent primary, anatomic MPFL-R with concomitant procedures at a single academic institution between 2010 and 2019. Patients with 5.55 mm ( P = .004) correlated with an increased risk of recurrent instability events. Conclusion: Anatomic MPFL-R paired with concomitant procedures as indicated is a safe, efficacious, and durable treatment option for lateral patellar instability in adolescent patients with an open or partially open distal femoral physis.
