Short-Term Outcomes After Derotational Femoral Osteotomy to Correct Abnormal Tibiofemoral Rotation in Patients With Recurrent Patellar Dislocations and Severe Rotational Malalignment

This study established that combined DFO and MPFL reconstruction yielded superior clinical outcomes relative to MPFL reconstruction performed with or without tibial tubercle osteotomy in patients with RPDs and excessive tibiofemoral rotation (>12°). Importantly, this therapeutic advantage was maintained even in patients exhibiting femoral anteversion ≤30°. Furthermore, DFO resulted in a mean reduction of 5° in tibiofemoral rotation at the final follow-up, in contrast to the control group, which showed no significant change.
