Realigning the knee joint

In a high tibial osteotomy the upper tibia bone is cut almost through and the bone wedged (usually an opening wedge) and fixed in place with a plate and screws until the bone heals in the new position. This is done to correct the forces going through the joint, frequently in patients with bow-leg (varus) deformity.
