Role of Osteotomy in Posterolateral Instability of the Knee.

Abstract

Injuries to the posterolateral corner (PLC) can be difficult injuries to successfully treat and are often associated with other injuries around the knee. Patients with varus malalignment can be even more difficult to manage when they have a PLC injury, resulting in double or triple varus and subsequent varus thrust during gait. A high tibial osteotomy (HTO) is a useful and necessary operation in patients with varus malalignment and a PLC injury, particularly in the chronic setting. The biomechanics, indications, surgical approach, and outcomes of HTO in the setting of PLC injury are reviewed in this article.
