Abstract: Objective: To explore the effect of health intervention based on health ecology theory on rehabilitation of patients with Total Knee Arthroplasty. Methods: Totally 72 patients were randomly divided into control group and observation group. At discharge and after discharge, the control group received health intervention according to the routine of Total Knee Arthroplasty, while the observation group received health intervention based on health ecology theory. HSS scale and SF-36 scale were used to evaluate the knee joint function and quality of life of patients in both groups at discharge, 3 months and 6 months after discharge. Results: HSS scale scores and SF-36 scores of the two groups showed no statistical difference at discharge (P>0.05). The scores of HSS scale and SF-36 scale in the observation group were higher than those in the control group at 3 months and 6 months after discharge, and the difference was statistically significant respectively (P﹤0.05). Conclusion: Health behavior intervention program based on health ecology theory can effectively improve the joint function and quality of life of patients with Total Knee Arthroplasty.
