Risk of chronic opioid use after simultaneous versus staged bilateral knee arthroplasty.
Several studies have identified excess risk associated with undergoing simultaneous (compared with unilateral or staged) bilateral total knee arthroplasty (BTKA). However, few have addressed subsequent chronic opioid use. Given the substantial morbidity and mortality associated with prolonged opioid use, we evaluated the incidence of postoperative chronic opioid use following simultaneous versus staged BTKA, based on the different timing strategies of staged procedures. ⋯ Although patients undergoing staged BTKA <6 months apart were prescribed greater quantities of opioids on discharge, there was no significant difference in the odds of postoperative chronic opioid use compared with simultaneous BTKA. The timing of BTKA procedures does not appear to influence the likelihood of postoperative chronic opioid dependence.
