Posterolateral Complex Reconstruction With Distal Femoral Varus Opening-Wedge Osteotomy for Unstable Neglected Multiligamentous Knee Injury With Valgus Malalignment

We presented a case of a 25-year-old woman with early posttraumatic degenerative change to the articular cartilage accompanied with valgus malalignment despite receiving anterior cruciate ligament reconstruction after a multiligamentous injury sustained 2 years earlier. Rapid deteriorating valgus malalignment may result from chronic instability and intra-articular bone loss. Simultaneous distal femoral varus osteotomy and posterolateral complex reconstruction were performed during a single surgery. Six months after the surgery, the patient could walk briskly and climb stairs without any discomfort. Salvage procedures and biological reconstruction could be the primary choice for young patients to recover their knee function while avoiding joint replacement.
