Sciatic nerve block provide superior analgesia for popliteal pain after total knee arthroplasty

Is sciatic nerve block advantageous when combined with femoral nerve block for postoperative analgesia following total knee arthroplasty? a meta-analysis

“…Five trials that compared SNB with various analgesic modalities, but lacked an appropriate FNB control group, were also excluded. 15,18,20,22,23 A single relevant RCT comparing single-shot FNB to single-shot FNB ? SNB was identified in the trial registries (clinical trials registry NCT02135120, relevant sample size = 30), but it was still in the recruitment phase with no available outcome results.…”

“…14 Recently, however, nine RCTs have been separately published, with seemingly mixed results. [15][16][17][18][19][20][21][22][23] In this updated meta-analysis, we aimed to quantify the analgesic effects of adding proximal single-shot or continuous SNB to single-shot or continuous FNB in the absence of LIA on analgesic consumption and pain scores during the first 48 hr postoperatively in adult patients undergoing unilateral TKA.…”
