title: Arthroscopic excision of heterotopic calcification in a chronic rectus femoris origin injury: a case report.
abstract: Rectus femoris origin injuries in adult athletes are uncommon. In the acute phase, conservative treatment seems to have a favourable outcome, with surgical repair reserved for unsuccessful cases only. However, a group of patients may develop chronic pain and disability after recovery  from the acute phase due to heterotopic calcification occurring at the site of injury. Open and arthroscopic excision of such calcifications has been described in the literature although arthroscopic excision of large calcified lesions in the rectus femoris has not been reported previously.  A relevant case is presented and discussed.
