Case in brief

A 44-year-old man with hereditary multiple exostoses presented with recurrent dislocation of the left patella. Imaging showed valgus deformity and trochlear dysplasia. He underwent a combined surgical approach involving lateral opening-wedge distal femoral osteotomy and medial patellofemoral ligament reconstruction. Post-surgery, the patient's patellar tracking improved, and there was no recurrence of dislocation.

Diagnostic / clinical pearl

In cases of complex patellofemoral instability, especially in hereditary multiple exostoses, addressing both bony alignment and soft-tissue insufficiency is crucial for successful outcomes.
