Randomized controlled trials (RCTs) comparing patients receiving iPACK plus SACB with patients receiving SACB after TKA were included. The included studies were assessed by two reviewers according to the Cochrane risk of bias criteria. Meta\u2010analysis was performed with STATA 13.0 software, the risk ratios (RR) and mean differences (MD) were used to compare dichotomous and continuous variables. The primary outcome was ambulation pain and secondary outcomes were rest pain, opioid consumption, function ability, clinical outcomes, and complications.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Seven RCTs (304 knees in iPACK + SACB group; 305 knees in SACB group) were included. The follow\u2010up periods ranged from 2\u2009days to 3\u2009months. Pooled data indicated lower pain scores at ambulation (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001) for iPACK + SACB. When comparing the pain scores of subgroups analyzed at specific periods, lower scores in subgroups within 12\u00a0h (at rest and ambulation) and after 48\u00a0h (at ambulation) were observed in the iPACK + SACB group. Analysis demonstrated greater reduction in morphine consumption (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.007) in the iPACK + SACB group. The iPACK + SACB group is also superior to the SACB group regarding function ability, which included range of motion (ROM) (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.001), time up to go (TUG) test (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.030), and ambulation distance (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001).
