Comparison of local infiltration of analgesia and sciatic nerve block in addition to femoral nerve block for total knee arthroplasty.
We conducted a prospective randomized controlled trial to test the null hypothesis that there is no difference between sciatic nerve block (SNB) and local infiltration of analgesia (LIA) regarding postoperative analgesia after total knee arthroplasty (TKA), when administrated in addition to femoral nerve block (FNB). Forty-six patients scheduled for TKA were randomized into two groups: concomitant administration of FNB and SNB or FNB and LIA. Average pain scores during the first 21days after surgery were similar in the two groups and remained at low level. There was no significant difference in the need for adjuvant analgesics, patient satisfaction level, the time to achieve rehabilitation goals, and length of hospital stay. The LIA offers a potentially safer alternative to SNB as an adjunct to FNB.
