Arthroscopic-assisted arthrodesis of the knee.

Arthrodesis of the knee is an accepted procedure to alleviate pain and deformity in posttraumatic degenerative arthritis, in patients who are not candidates for total joint arthroplasty. Most all of the accepted surgical methods involve an arthrotomy to remove bone and prepare the surfaces for fusion. We present an unusual case of posttraumatic arthritis of the knee in a young woman with a history of osteomyelitis. An arthrodesis was planned, but an arthrotomy was precluded. Arthroscopically assisted preparation of the fusion bed was performed for compression arthrodesis of the knee with an external fixator. A successful arthrodesis was obtained in 14 weeks.
