Preoperative opioid use and outcomes after reverse shoulder arthroplasty

Abstract

The potential adverse effect of preoperative opioid use on outcomes after reverse shoulder arthroplasty (RSA) has not been investigated. The purpose of this study was to evaluate outcomes after RSA in patients with a history of preoperative opioid use and compare them with a control group without a history of preoperative opioid use. Sixty-eight RSAs performed for rotator cuff tear arthropathy (CTA) with a minimum of 2years of follow-up were identified in a prospective shoulder arthroplasty registry. Thirty-two patients with a history of preoperative opioid use for shoulder pain were compared with a control group of 36 patients who did not use opioids preoperatively. Shoulder function scores and range of motion measurements were assessed preoperatively and at the final follow-up. No differences were noted between the 2 groups in age, gender, duration of follow-up, depression, smoking, chronic back pain, diabetes, heart disease, or body mass index. Preoperative opioid use was associated with significantly lower preoperative shoulder function scores. Both groups significantly improved on all shoulder function scores and for range of motion measurements from the preoperative to the final follow-up assessment; however, the nonopioid group had significantly better outcomes. The magnitude of change between the groups from preoperatively to the final follow-up was nearly identical. Improvements can be expected in patients with a history of preoperative opioid use; however, patients with preoperative opioid use have a lower preoperative baseline and should not expect to reach the same peak outcome scores after RSA as patients without a history of preoperative opioid use.
