Abstract

Background: Nonsteroidal anti-inflammatory drugs are commonly utilized to reduce the risk of developing heterotopic ossification (HO) after hip arthroscopy. However, it is not known which regimen is optimal.

Purpose: The purpose of this study is to determine the rate of HO formation after hip arthroscopy in response to different NSAID protocols.

Methods: Consecutive cases of a single fellowship-trained surgeon at a tertiary referral center were retrospectively reviewed. Patients received a regimen of two medications, starting with four days of either Ketorolac or Indomethacin and ending with either Celecoxib, Meloxicam, Diclofenac, or Naproxen. Two reviewers assessed HO on postoperative radiographs.

Results: 323 cases were included for retrospective review. 48 (15 %) were found to develop HO after hip arthroscopy. Patients who also underwent labral repair (p = 0.046) and those with larger corrections in alpha angle (p = 0.048) were found to have higher rates of HO. Multivariate regression found that receiving Meloxicam as a second medication was found to have a significantly higher risk of HO than Celecoxib (OR 4.72, p = 0.035). Male gender (OR 2.36, p = 0.013), was also found to be associated with a higher likelihood of HO formation according to the model.

Conclusion: While taking Meloxicam as the second NSAID was associated with a significantly higher rate of HO than Celecoxib, no one regimen was found to be superior. Additionally, male gender was found to be a significant predictor of HO development.
