Preoperative opioid medication use negatively affect health related quality of life after total knee arthroplasty

Our results demonstrated that TKA patients with preoperative opioid use had significantly lower VAS scores and trends of lower UCLA and EQ-5D scores postoperatively compared to non-opioid patients, suggesting the use of opioid medications prior to TKA negatively affects patient reported outcomes following surgery. The current findings provide useful clinical information that can be used in counseling patients prior to undergoing TKA.
