145 patients scheduled for total knee arthroplasty were randomized to a perioperative regimen consisting of either spinal anaesthesia combined with continuous adductor canal block, general anaesthesia combined with continuous adductor canal block, or combined spinal-epidural anaesthesia. Patients were primarily assessed for walking distance during postoperative physical therapy. Both groups which received the adductor canal block demonstrated significantly higher ambulation distances compared to the combined spinal-epidural anaesthesia group. In addition, the spinal anaesthesia plus adductor canal block group demonstrated a significant analgesic benefit relative to the combined spinal-epidural anaesthesia group.
