Abstract
Background: We sought to determine whether regional nerve block, cryotherapy variant, or patient-specific factors predict postoperative opioid requirements and pain control following hip arthroscopy. Methods: 104 patients underwent hip arthroscopy with (n = 31) or without (n = 73) regional block and received cryotherapy with a universal pad [joint non-specific; no compression (n = 60)] or circumferential hip/groin wrap with intermittent compression (n = 44). Outcomes included total opioid prescription amounts, requests for refills, and unplanned clinical encounters for postoperative pain within 45 days of surgery. Multivariate modeling was used to determine the effect of perioperative regional nerve block and type of cryotherapy device on outcomes after adjusting for patient demographics, previous opioid use, mental health disorder history, and surgery length. Results: The average amount of 5 mg oxycodone pill equivalents prescribed within 45 days of surgery was 40.5 (SD 14.8); 36% requested refills, 20% presented to another physician, and 21% called the surgeon's office due to pain. Neither the hip-specific cryotherapy pad nor regional block was predictive of opioid amounts prescribed, refill requests, or unplanned clinical encounters due to pain. Refill requests within 45 days were more common with baseline opioid use (p < 0.001), increased age (p = 0.007), and mental health disorder history (p = 0.008). Total opioid amounts prescribed within 45 days were higher with workers compensation (p = 0.03), a larger initial opioid prescription (p < 0.001), baseline opioid use (p < 0.001), history of mental health disorder (p = 0.02), and increased age (p = 0.02). Together, these variables explained 61% of the variance in opioid amounts prescribed. Conclusion: Patient factors are strong predictors of postoperative opioid requirements after hip arthroscopy. Postoperative opioid prescription amounts, opioid refill requests, and pain-related calls or office visits were not affected by use of a perioperative regional nerve block or type of cryotherapy delivery system. Level of evidence: III, retrospective cohort study.
