Comparison of Adductor Canal Block and Femoral Nerve Block for Postoperative Pain in Total Knee Arthroplasty

View Article: PubMed Central - PubMed

ABSTRACT

A total knee arthroplasty (TKA) has always been associated with moderate-to-severe pain. A systematic review of randomized controlled trials (RCTs) and non-RCTs was performed to evaluate the efficacy and safety of pain control of adductor canal block (ACB) and femoral nerve block (FNB) after TKA.

Relevant literatures about the ACB and FNB after TKA for reducing pain were searched from Medline (1996-January, 2015), Embase (1980-January, 2015), PubMed (1980-January, 2015), Web of Science (1980-January, 2015), and The Cochrane Central Register of Controlled Trials. High-quality RCTs and non-RCTs were picked to evaluate the visual analogue scale (VAS) and other outcome. This systematic review and meta-analysis were performed according to the PRISMA statement criteria. The software RevMan 5.30 was used for the meta-analysis.

Eight literatures fitted into the inclusion criteria. There were no significant differences in VAS score with rest or mobilization at 4, 24, and 48 h between ACB group and FNB group. There were also no significant differences in the strength of quadriceps and adductor, the length of hospital stay, and complications of vomiting and nausea.

Present meta-analysis indicated that ACB shows no superiority than FNB group. Both of them can reduce the pain score after TKA. As referred to which method to adopt, it is determined by the preference of the surgeons and anesthesiologists.

Mentions: The electronic databases including Medline, Embase, PubMed, CENTRAL (Cochrane Controlled Trials Register) Web of Science, and Google database were searched for relevant studies involving ACB and FNB in the management of pain relief after TKA in January 2015. The key words and its medical subject heading (Mesh) terms “adductor canal block” “femoral nerve block” “total knee arthroplaty” “total knee replacement” “TKA” “TKR” were combined with Boolean operators AND or OR. The search strategy was presented in Figure 1. Furthermore, the reference lists of all the full-text literatures were reviewed to identify any initially omitted studies and no restrictions on the language of the publication. And the duplicates were excluded by the software of Endnote X7.
