Patellofemoral instability is a common condition usually seen in adolescent females. With increasing age and athletic activity, men are more likely to experience patellofemoral injuries, including traumatic dislocations. The articular geometry, muscle action, and passive soft tissue restraints are the principal anatomic factors that affect stability. Recurrent instability is linked to prior episodes of patella instability, malalignment, and injury to the medial soft tissue restraints. The authors’ preferred treatment algorithm including both non-operative and operative approaches is discussed.
