Editorial Commentary: Be Careful With Preoperative Injections Prior to Hip Arthroscopy—Use a Three-Month Threshold to Reduce Infection Risk

A large private insurer and Medicare in the United States was queried to evaluate the risk of postarthroscopic hip infection in patients who had preoperative injections.
