High Tibial Osteotomy
A High Tibial Osteotomy is an operation that involves cutting your tibia (shin) bone to realign the weight-bearing axis of the leg. The purpose is to take body weight off an arthritic part of the knee. HTO surgery can also be used in certain cases to treat instability of the knee. When the tibia bone is wedged open, the gap is filled with bone graft. This can come from your pelvis (autograft) or from the bone bank (allograft). Synthetic bone graft can also be used along with, or as an alternative to, the autograft or allograft.
