Meta analysis of efficacy and safety of non-steroidal anti-inflammatory drugs in preventing heterotopic ossification after hip arthroscopy

Abstract

Objective To evaluate the efficacy and safety of non-steroidal anti-inflammatory drugs (NSAIDs) in preventing heterotopic ossification after hip arthroscopy. Methods Literature search was conducted in PubMed, Embase, Cochrane Library, CNKI and Wanfang data with time range from January 1973 to November 2017. Clinical case control articles on NSAIDs in preventing heterotopic ossification after hip arthroscopy were screened based on the inclusion and exclusion criteria. Meta analysis was done using RevMan 5.3 software to investigate the incidence of complications such as heterotopic ossification and gastrointestinal bleeding after hip arthroscopy in patients taking NSAIDs orally. Results Six articles were included in the study, with a total of 754 cases and 536 controls. NSAIDs reduced the incidence of heterotopic ossification after hip arthroscopy (RR=0.09, 95%CI 0.03-0.27, P 0.05). Conclusion NSAIDs can effectively reduce the incidence of heterotopic ossification after hip arthroscopy and does not increase the incidence of postoperative gastrointestinal complications. Therefore, it is effective and safe to use NSAIDs to prevent the occurrence of heterotopic ossification after hip arthroscopy.
