Neglected Rotatory Knee Dislocation Treated with the Taylor Spatial Frame

This case is about a young woman with a neglected rotatory knee dislocationRotatory knee dislocation associated with fixed malrotation of the tibia with respect to the femur, valgus instability, lateral patellar dislocation, and knee stiffness. Correction of the rotational deformity was carried out both acutely after lysis of adhesions and gradually with the use of a Taylor Spatial Frame (TSF). However, patellar dislocation persisted which necessitated a tibial tubercle osteotomy and transfer, which resulted in excellent patellar alignment and tracking. Residual knee stiffness was subsequently managed by quadricepsplasty. At 8 years postoperatively, the patient had a very good knee range of motion (0–90° flexion), no instability, and normal patellar tracking.
