| Objective: To study the effects of home tele-rehabilitation guidance on function of knee in patients after total knee arthroplasty (TKA). Methods: A total of 120 elderly patients who received a unilateral TKA were enrolled in this study. The participants were randomized into the control group and the rehabilitation group, both of which had finished rehabilitation while in hospital. The patients in the control group self-exercised after discharge, and those in the rehabilitation group received the home tele-rehabilitation guidance after discharge. WOMAC questionnaire score and ROM before and after the treatment were recorded respectively. Results: After treatment of 1, 3, 6, 9 and 12 weeks, the WOMAC scores of two groups were obviously decreased as compared with those of before (pain, dysfunction, stiff) (P<0.05), active and passive ROM scores of both groups increased obviously (P<0.05), and after treatment of 6, 9 and 12 weeks, WOMAC scores and active and passive ROM scores in rehabilitation group changed more than those in control group (P<0.05). Conclusion: Rehabilitation in hospital and home tele-rehabilitation guidance could significantly improve the patient's function of knee after TKA. |
