title: Periarticular heterotopic ossification: a complication of arthroscopic anterior cruciate ligament reconstruction using a two-incision technique.
abstract: Extra-articular heterotopic bone formation was recognized as a postoperative complication of arthroscopic anterior cruciate ligament reconstructions in four knees around the femoral drill hole. Although laxity of the reconstructed anterior cruciate ligament was not observed in these patients, local pain, swelling, and deformity at the site of heterotopic ossification required surgical intervention. The ectopic bone can be successfully excised with restoration of function. The incidence rate of this complication is less than 1%.
