Postoperative analgesic efficacy of fascia iliaca block versus periarticular injection for total knee arthroplasty

The efficiency and safety of fascia iliaca block for pain control after total joint arthroplasty

“…All of the RCTs [10–14] reported a clear inclusion and exclusion criteria and suggest a methodology of randomization, all of them demonstrated that randomization sequence was generated by computer. Three of them [10,12,13] reported allocate concealment was achieved by sealed envelopes. Double blinding was provided in 2 RCTs [10,14] .…”

“…Four studies [10–13] reported VAS scores at 12 hours following TJA. Statistical heterogeneity was observed in present meta-analysis (χ2 = 9.46, df = 3, I 2  = 68.3%, P  = .024); therefore, a random-effects model was applied.…”

“…Morphine consumption at postoperative 12 hours was presented in 4 studies [10–13] following TJA. There was no significant heterogeneity (χ2 = 4.52, df = 3, I 2  = 33.6%, P  = .210) and a fixed-effects model was used.…”

“…Three studies [10,11,13] reported the length of hospital stays between groups. No significant heterogeneity was identified in the pooled results; therefore, a fixed-effects model was used (χ2 = 1.19, df = 2, I 2  = 0%, P  = .551).…”

“…[10–13] No significant heterogeneity among these studies was found; therefore, a fixed-effects model was used (χ2 = 4.64, df = 3, I 2  = 35.3%, P  = .201). There was significant difference between the 2 groups in the incidence of nausea and vomiting (RD = –0.139, 95% CI: –0.243 to –0.034, P  = .009; Fig.…”
