Arthroscopic fixation of osteochondritis dissecans. Outpatient treatment for condylar defects.

According to a 1990 study, 88% of the patients assessed their postoperative result as excellent or good after two years of follow up. One disadvantage to this repair is the need for a second arthroscopy for compression screw removal; however, this allows the surgeon an opportunity to assess healing. Surgeons are continuing to advance arthroscopic surgery by using supplemental bone grafts, with or without compression screw fixation. Arthroscopic compression screw fixation of osteochondritis dissecans is a progressive alternative for patients who may otherwise have been candidates for an open-knee arthrotomy.
