Combined femoral and sciatic nerve block vs combined femoral and periarticular infiltration in total knee arthroplasty: a randomized controlled trial.

This study tests the null hypothesis that there is no difference between sciatic nerve block (SNB) and periarticular anesthetic infiltration (PI) as adjuncts to femoral nerve blockade (FNB) in total knee arthroplasty in terms of postoperative opioid requirements. Fifty-two patients undergoing total knee arthroplasty were randomized to receive either (a) combined FNB-SNB or (b) combined FNB-PI. Average morphine consumption in the first 24 (20 vs 23 mg) and 48 hours (26 vs 33 mg) showed no significant difference.
