Advantages, Risks, and Limitations of Autologous Osteophyte Grafting in OW-HTO

Advantages

Harvesting and implantation of autologous osteophyte grafts are easy in OW-HTO.

Additional skin incision is unnecessary.

Bone-healing periods are shortened.

Knee extension is improved.

Risks and limitations

Bone fragments may be left inside the knee joint.

Hemarthrosis may be prolonged.

Small amounts of the harvested osteophytes may be prepared in early OA.

A prospective, randomized, comparative study should be carried out in the future.

OA, osteoarthritis; OW-HTO, open-wedge high tibial osteotomy.
