Heterotopic Ossification in Hip Arthroscopy: an Updated Review

Adrian Z Kurz et al. Curr Rev Musculoskelet Med. 2019 Jun.

Abstract

Purpose of review: Heterotopic ossification (HO) in hip arthroscopy is a common post-operative complication. This review was undertaken to provide an update (2014 present) on the current literature regarding HO in hip arthroscopy.

Recent findings: Risk factors for HO post-hip arthroscopy include male gender, mixed impingement, picture, and the size of CAM resection. HO prophylaxis with NSAIDs has been proven to decrease the rate of HO post-hip arthroscopy; however, there is inherent risk to long-standing NSAIDs therapy. HO post-hip arthroscopy is not uncommon as a radiological finding, but symptomatic HO post-hip arthroscopy requiring revision surgery is a rare event, at < 1%. The outcomes for revision surgery for HO excision have fair outcomes. The hip arthroscopist should stratify their patients based on known risk factors, and determine whether NSAIDs prophylaxis is warranted.

Keywords: Complication; Heterotopic ossification; Hip arthroscopy; NSAIDs; Prophylaxis; Revision surgery.
