Corrective Osteotomy

Corrective osteotomy is a surgical procedure used for treatment of deformities of the knee, namely, bowlegs (genu varum) and knock-knees (genu valgum). These deformities result in overloading and overuse of a compartment of the knee. This results in the early development of arthritis. Corrective osteotomy can be considered if the disease is not in the advanced stages, if the patient is relatively young, if the knee is otherwise healthy, and if all conservative options have been exhausted. In corrective osteotomy, a wedge of bone is removed from the tibia (shin bone) at a site determined during preoperative planning in order to correct the deformity and establish an anatomically correct leg axis. The surgery achieves good to excellent results in approximately 80 percent of cases.
