title: Osteonecrosis of the knee following laser-assisted arthroscopic surgery: a report of six cases.
abstract: We report six cases where significant postoperative pain persisted in individuals following arthroscopic surgery augmented with the use of lasers. Subsequent magnetic resonance images showed lesions with signal changes compatible with the diagnosis of osteonecrosis in areas directly addressed with laser energy.
