Objective To investigate the effect of early rehabilitation care on the rehabilitation effect and quality of life in patients underwent total hip arthroplasty（THA）.Methods Sixty-four patients who underwent THA treatment in a hospital in Guangzhou from May 2017 to February 2020 were selected as subjects and assigned to a control group and a study group using the random number table method

with 32 subjects in each group.The patients in the control group received conventional orthopedic care

and the patients in the study group received early rehabilitation care after the conventional care

and participants in both groups received continuous care for 3 months.The Harris hip function score

modified Barthel index score

and the MOS item short from health survey（SF-36） score were compared between the two groups of patients before surgery and at 3 months of care.Results The Harris hip function score

Barthel index score

and SF-36 score of patients before surgery in 2 groups were compared

and the differences were not statistically significant（P>0.05）.At 3 months of care

the Harris hip function scores

Barthel index scores

and SF-36 scores of patients in the 2 groups were higher than those before surgery

and the study group had higher scores than the control group

with statistically significant differences（P<0.05）.Conclusion The early post-operative rehabilitation care for patients underwent THA can significantly improve their hip function

activity of daily life and quality of life.
