Intra-articular correction of extra-articular tibial deformities with total knee arthroplasty

摘要

INTRODUCTIONExtra-articular leg deformities may occur in the femur or tibia from mal-unions from previous trauma or metabolic bone disease. Secondary osteoarthritis at the knee occurs due to loss of mechanical alignment of the limb. At surgery for total knee arthroplasty, mechanical alignment can be restored intra-articularly with appropriate bone cuts and soft tissue balancing.
