To determine the prevalence of preoperative opioid use in patients with femoroacetabular impingement (FAI) syndrome and to define how opioid use influences preoperative hip pain and function at a single center. Between February 2015 and September 2016, patients undergoing hip arthroscopy at a single Midwest institution for FAI syndrome were retrospectively reviewed. Patients undergoing arthroscopy for non-FAI conditions and those with undocumented preoperative opioid use were excluded. Baseline validated measures (Hip Disability and Osteoarthritis Outcome Score [HOOS] pain and physical function; University of California, Los Angeles, activity scores; Veterans RAND 12 Item Health Survey) of health were collected at the time of surgery. Articular cartilage status was documented at the time of surgery. Opioid use was extracted from the electronic medical record retrospectively, and patients were designated current users, past users, or nonusers. Analysis of variance and 2-tailed Student's t-tests were used to detect differences between groups according to preoperative opioid use, and significance was set to P < .05. During the study period 321 patients underwent arthroscopic hip surgery for FAI and met the inclusion criteria (75 were excluded). Preoperatively, 55 patients (17%) were current opioid users, 89 (28%) were past users (not within 3months of surgery), and 177 (55%) were opioid naive. Current opioid use was associated with significantly worse measures of joint and general health including HOOS-Pain (15.3 point difference, P < .001), HOOS-Physical Function (13.6 point difference, P < .001), University of California, LosAngeles, activity score (1.7 point difference, P < .001), and Veterans RAND 12 Item Health Survey mental component score (5.5 point difference, P < .001). Outerbridge cartilage grading and presence or length of labral tears were not worse in opioid users (P= .2-.61). Preoperative opioid use is common prior to arthroscopy for FAI and has detrimental impacts on hip pain and function. The present data also suggest cessation of opioid medication for 3months prior to surgery may have meaningful impacts on baseline measures of hip and general health. Level III, prognostic.
