[Is synovectomy a sure treatment procedure for synovial osteochondromatosis?]

In recent literature synovectomy is recommended for treating osteochondromatosis. In the case of a 25-year-old woman with an affected knee joint, who was treated with synovectomy, the authors observed recurrence 5 years later. Ten years after the operation a severe osteoarthritis had developed. Our experience suggests that this method should not be overestimated. F. Kroh came in 1932 to the same conclusion.
