Distal Femoral Osteotomy and Medial Patellofemoral Ligament Reconstruction for Patellar Dislocation in Hereditary Multiple Exostoses: A Case Report.

CASE: A 44-year-old man with hereditary multiple exostoses (HME) presented with recurrent patellar dislocation of the left knee. Radiographs revealed valgus deformity and trochlear dysplasia. The patient underwent lateral opening-wedge distal femoral osteotomy with medial patellofemoral ligament reconstruction using FiberTape and knotless SwiveLock anchors. Postoperatively, patellar tracking normalized with no recurrence.

CONCLUSIONS

This case highlights the need to address bony alignment and medial soft-tissue insufficiency concurrently in complex patellofemoral instability, particularly in HME, to achieve stable outcomes.
