36 patients scheduled to undergo revision total knee arthroplasty were randomly assigned to adductor canal block with ropivacaine or placebo. The purpose of this study was to evaluate whether an adductor canal block reduced postoperative pain to a significant degree. The primary outcome of interest was VAS pain during knee flexion at 4 hours postoperatively. Results indicated a significantly greater reduction in pain at 4 hours postoperatively in the adductor canal block group than the placebo group. However, due to a large dropout rate, the findings from this trial alone cannot support the use of adductor canal block for the management of postoperative pain after revision total knee arthroplasty.
