Abstract: Objective To investigate the effects of enhanced recovery after surgery(ERAS) on postoperative recovery following total knee arthroplasty(TKA) by comparing postoperative functional results. Methods Depending on whether the ERAS regimen was used, a total of 1 881 inpatients who were diagnosed with knee osteoarthritis at Beijing Chaoyang Hospital, Capital Medical University, from January 1, 2010 to December 31, 2021, were divided into an ERAS group and a control group. Basic information, knee range of motion, American Knee Society Score(KSS), the Western Ontario and McMaster Universities(WOMAC) osteoarthritis score were withdrawn before and one month after surgery. Additionally, the satisfaction was recorded one month after surgery. Results After the implementation of ERAS program, the hospitalization duration and hospitalization cost in ERAS group were significantly lower than those in the control group (P<0.01). At one month after surgery, patients in the ERAS group had significantly greater postoperative satisfaction than patients in the control group and significantly better KSS clinical and functional scores and knee range of motion than patients in the control group(P<0.05). At one month following surgery, there was no apparent change in the WOMAC scores between the two groups (P>0.05).Conclusion Better postoperative function and satisfaction can be attained with TKA using the ERAS protocol, while the hospital duration and cost are decreased.
