Abstract
We have utilized arthroscopic arthroplasty of the hip joint (arthroscopic partial resection of the acetabular edge) for the treatment of advanced osteoarthritis of hip joint.
We have utilized arthroscopic Arthroplasty to widen the joint space and tried to improve the outcome of joint preserving operation. We have treated advanced osteoarthritis of nine hip joints of eight patients (age from 41 to 56, averaged 44.3 years old) by arthroscopic arthroplasty in the past six years. The patient was put on the surgical traction table in the supine position. Arthroscope was inserted into the hip joint from antero-medial approach under fluoroscopic control and the acetabular edge was shaved until bleeding from subchondral bone was seen. In eight joints of seven patients, additional surgical procedures were applied later.
Acetabular edge resection alone might resulted in the lateral-proximal displacement of the femoral head and to acquire good result in the long term, some additional procedure should be considered. However, in one case of this series showed good roof osteophyte formation after arthroscopic arthroplasty with improved JOA score. This might be a result of improved blood supply at the edge of acetablum. We believe that arthroscopic arthroplasty for advanced osteoarthritis in combination with other procedures may avoid total hip arthroplasty.
