Heterotopic ossification in portal sites following hip arthroscopy

Heterotopic ossification (HO) is a well-known condition that usually occurs after head trauma, burns and open surgical procedures, most commonly around the hip and elbow joints. It is a well-documented complication occurring after open hip surgery; however, there exists limited information regarding its prevalence and clinical importance following hip arthroscopy. We report a case of symptomatic HO formation in portal sites following arthroscopic rim decompression, femoroplasty and labral debridement that was successfully treated with arthroscopic removal.
