Habitual dislocation of the patella is a rare condition characterized by the patella dislocating upon knee flexion and spontaneously returning to its normal position upon extension. Unlike recurrent dislocation, habitual dislocation is typically painless and asymptomatic. Management of this condition often requires a combination of surgical procedures due to the lack of universally effective single interventions. Herein, we present the case of a 17-year-old girl with habitual patellar dislocation who underwent surgical treatment at our hospital. The surgical approach involved lateral patellofemoral release, reconstruction of the medial patellofemoral ligament using a harvested semitendinosus graft, and medialization of the patellar tendon with tibial tuberosity osteotomy. The patient's recovery was uneventful, and she resumed routine activities comfortably after six months of follow-up. Discussion highlights the pathophysiology of habitual patellar dislocation, emphasizing the importance of addressing both lateral retinaculum shortening and medial stabilization. Overall, a combined surgical approach targeting these factors tends to yield favorable outcomes in managing habitual patellar dislocation cases.
