Sixty-three patients undergoing total knee arthroplasty were randomized to receive either a surgeon-performed continuous adductor canal block (cACB; n=29) or an anesthesiologist-performed cACB (n=30). The primary outcome of interest was pain during movement at 24 hours postoperatively, measured using the visual analog scale (VAS). Secondary outcomes included pain at rest, morphine consumption, quadriceps strength, knee range of motion, time up and go (TUG) tests, and patient satisfaction. Outcomes were assessed up to 48 hours postoperatively. Overall, the results of the study revealed that there were no significant differences in VAS during movement or other functional outcomes between the groups. The study concluded that surgeon-performed cACB is a feasible and effective alternative to anesthesiologist-performed cACB in TKA patients.
