Anterior Opening-Wedge Proximal Tibial Osteotomy for Symptomatic Genu Recurvatum and Osteochondral Autograft Transfer for Osteochondral Defect.

Acute knee hyperextension injuries are more frequently sustained during athletic trauma and can cause symptomatic pain, soft-tissue laxity of the knee, malalignment, and ligament strain. Decreased posterior tibial slope is correlated with a higher degree of knee hyperextension, and although not the only cause, it can contribute to symptomatic genu recurvatum. In the context of acute knee hyperextension, chondral lesions may occur secondarily but are more often caused by limb malalignment and overuse. In the setting of symptomatic genu recurvatum and an osteochondral defect, it is vital to restore the native joint biomechanics. We describe the use of anterior opening-wedge proximal tibial osteotomy to correct symptomatic genu recurvatum and osteochondral autograft transfer to repair a full-thickness chondral defect. Past studies have shown long-term successful functional outcomes for both anterior opening-wedge proximal tibial osteotomy and osteochondral autograft transfer procedures, with most patients returning to their preinjury activity levels.
