Objective:
To compare pericapsular nerve group block combined with lateral femoral cutaneous nerve block (PENG+LFCN) with fascia iliaca compartment block (FICB) for postoperative analgesia and functional recovery after hip surgery within Enhanced Recovery After Surgery (ERAS) pathways.
Methods:
PubMed, Embase, the Cochrane Library, CNKI, Wanfang Data, and CQVIP were searched through January 2026. Comparative studies of PENG+LFCN versus FICB in hip surgery were included. Data were pooled using a random-effects model, with assessment of bias, heterogeneity, and publication bias.
Results:
Sixteen studies were included. The PENG+LFCN group had significantly lower resting VAS (MD = -0.54; p < 0.00001) and dynamic VAS (MD = -0.98; p < 0.00001) scores. It also showed a lower incidence of postoperative muscle weakness (OR = 0.10; p = 0.0001), better preservation of quadriceps muscle strength, shorter time to first ambulation (MD = -9.22 h; p < 0.0001), and reduced length of stay (MD = -0.75 days; p < 0.00001). Additionally, morphine consumption (MD = -24.22 mg; p = 0.001) and PCA pump activations (MD = -2.46; p < 0.00001) were lower in the PENG+LFCN group.
Conclusion:
PENG+LFCN may be a more favorable regional analgesic strategy than FICB for hip surgery within ERAS pathways.
