Simultaneous tibial osteotomy and total knee arthroplasty in posttraumatic and obese patient: a case report

Deforming osteoarthritis of the knee joint alters the mechanical axis of the lower limb. This, combined with extra articular deformity of the tibia or femur leads to serious dysfunction of the limb and great disability for the patient. These rare cases present great challenge for the orthopedic surgeon. Most of the cases with mild to moderate deformities can be successfully managed by adjusting intra articular resections, but in those with severe extra articular deformity, an extra articular correctional osteotomy may be required in order to achieve good flexion-extension balance of the knee. We report a case of total knee replacement performed together with correctional osteotomy of the tibia due to extra articular deformity of about 20 degree varus.
