OBJECTIVE: To determine the effect of rehabilitation education on pain, knee stiffness and performance difficulty in patients undergoing knee replacement surgery. METHOD(S): This randomized clinical trial study was performed on 96 patients undergoing knee replacement surgery, who were randomly divided into two groups: the control group and the intervention group, with 48 patients in each group. In the intervention group, the patients received educational intervention in four stages (one day before surgery, 24 h and 48 h later, upon discharge from the hospital. In the control group, only the routine of the hospital was performed. Questionnaires were completed before and 6 weeks after the intervention. RESULT(S): The mean scores of pain, knee stiffness and performance difficulty were significantly decreased in the intervention group (p = 0.01). Compared to the control group, the intervention group had a better outcome of the illness, including pain, knee stiffness and performance difficulty (p = 0.001). CONCLUSION(S): Rehabilitation education could be a suitable way to improve the surgical outcomes of patients undergoing total knee replacement.
