Local Infiltration Anesthesia Provides No Added Benefit in Primary Total Hip Arthroplasty
Local Infiltration Anesthesia in Total Hip Arthroplasty: A Randomized Controlled Trial.
Arthroplast Today . 2025 May 26:33:101692.One hundred eight patients with coxarthrosis scheduled for primary Total Hip Arthroplasty (THA) were randomized to receive Local Infiltration Anesthesia (LIA) (n=52) or no LIA (n=56). The primary outcome was postoperative pain (VAS) at 24 and 48 hours. Secondary outcomes included intraoperative blood loss, length of stay, Harris Hip Score (3 and 6 months), patient satisfaction (3 and 12 months), and complications. Follow-up extended to 12 months. Overall, the results of the study revealed no significant between-group differences in VAS at 24 hours or 48 hours, nor in blood loss, length of stay, functional recovery, or satisfaction. In short, LIA did not confer measurable clinical benefit after primary THA in this trial.
