Abstract

Study design Systematic review with meta-analysis.

Objectives To evaluate the effects of enhanced recovery after surgery (ERAS) on the postoperative recovery of patients who underwent total hip arthroplasty (THA) or total knee arthroplasty (TKA).

Methods The PubMed, Embase, Cochrane and ISI Web of Science databases were searched to identify literature including randomised controlled trials (RCTs), cohort studies and case–control studies through 2 May 2018. The analysed outcomes were mortality rate, transfusion rate, range of motion (ROM), 30-day readmission rate, postoperative complication rate and in-hospital length of stay (LOS).

Results A total of 25 studies involving 16 699 patients met the inclusion criteria and were included in the meta-analysis. Compared with conventional care, ERAS was associated with a significant decrease in mortality rate (relative risk (RR) 0.48, 95% CI 0.27 to 0.85), transfusion rate (RR 0.43, 95% CI 0.37 to 0.51), complication rate (RR 0.74, 95% CI 0.62 to 0.87) and LOS (mean difference (MD) −2.03, 95% CI −2.64 to −1.42) among all included trials. However, no significant difference was found in ROM (MD 7.53, 95% CI −2.16 to 17.23) and 30-day readmission rate (RR 0.86, 95% CI 0.56 to 1.30). There was no significant difference in complications of TKA (RR 0.84, 95% CI 0.34 to 2.06) and transfusion rate in RCTs (RR 0.66, 95% CI 0.15 to 2.88) between the ERAS group and the control group.

Conclusions This meta-analysis showed that ERAS significantly reduced the mortality rate, transfusion rate, incidence of complications and LOS of patients undergoing TKA or THA. However, ERAS did not show a significant impact on ROM and 30-day readmission rate. Complications after hip replacement are less than those of knee replacement, and the young patients recover better.
