Abstract
BACKGROUND: Total knee arthroplasty (TKA) is accompanied by moderate-to-severe postoperative pain. Postoperative pain will hamper functional recovery and lower patients' satisfaction with surgery. Recently, periarticular local infiltration analgesia (LIA) has been widely used in TKA. However, there is no definite answer as to the efficacy and safety of LIA compared with femoral nerve block (FNB). METHOD: Randomized controlled trials about relevant studies were searched from PubMed (1996 to July 2017), Embase (1980 to July 2017), and Cochrane Library (CENTRAL, July 2017). Ten studies which compared LIA with FNB methods were included in our meta-analysis. RESULTS: Ten studies containing 950 patients met the inclusion criteria. Our pooled data indicated that LIA was as effective as the FNB in terms of visual analog scale score for pain at 24 hours (P = .52), 48 hours (P = .36), and 72 hours (P = .27), and total morphine consumption (P = .27), range of motion (P = .45), knee society score (P = .51), complications (P = .81), and length of hospital stay (P = .75). CONCLUSIONS: Our current meta-analysis results demonstrated that there were no differences in efficacy between the FNB and LIA method.
