Randomized Controlled Trial Comparative Study
Local Infiltration Analgesia Versus Continuous Femoral Nerve Block in Pain Relief After Total Knee Arthroplasty: A Randomized Controlled Trial.
Although both local infiltration analgesia (LIA) and continuous femoral nerve block (FNB) are common analgesic modalities for pain relief after total knee arthroplasty (TKA), we are aware of no parallel-group, randomized controlled trial that has solely compared the efficacy of LIA and continuous FNB. ⋯ LIA was associated with better pain relief with a comparable complications rate for patients undergoing TKA than FNB. We recommend LIA for pain relief after TKA.
