Analgesic efficacy of local infiltration anaesthesia versus femoral nerve block in alleviating postoperative wound pain following total knee arthroplasty: A systematic review and meta-analysis.

研究概要

Eight randomized controlled trials including a total of 454 patients undergoing total knee arthroplasty were included in this systematic review and meta-analysis comparing local infiltration anaesthesia (LIA) versus femoral nerve block (FNB). Pooled outcomes of interest included pain scores at rest and during movement, opioid consumption, and patient satisfaction. The results indicated no significant difference in resting and movement-related pain scores between LIA and FNB groups. However, LIA was associated with significantly lower opioid consumption. The main findings suggest that while both LIA and FNB are effective for pain control, LIA offers the added benefit of reducing opioid use, making it a preferable choice for postoperative analgesia in knee replacement surgeries.
