Department of Orthopaedic Surgery Faculty Papers

Anatomic aberrations of the femur and tibia secondary to trauma, congenital defects, and prior surgery present challenges for the reconstructive knee surgeon because of an altered mechanical axis and distorted anatomic landmarks. Five patients with arthritis of the knee and extra-articular femoral and/or tibial deformity, retained hardware, or intramedullary (IM) implants underwent total knee arthroplasty using a computer navigation system. The navigation system obviated the need for an IM guide, and the normal mechanical axis of the patients was restored. Extensive dissection for hardware removal or osteotomy was not necessary in these patients. In these 5 cases, a navigation system …
