| Objective: To compare the effectiveness of early continuous passive motion on rehabilitation of the patients after total knee Arthroplasty(TKA).Methods: The study was a prospective, single-blind and randomized clinical trial. 78 patients were recruited in this study, who received TKA at changzheng hospital between February and October 2006 and agreed to participate in it. On admission, patients were randomly assigned to one of the following two groups:(1)Control group , in which patients received conventional physical therapy alone; (2)Experimental group, in which patients had conventional physical therapy and additional CPM for 2 30- minutes daily. The experimental group started the CPM on the first postoperative day and lasted 14 days. The starting range was 0 to 40 degrees, and the range of movement increased about 5 to 10 degrees daily. Patients practised CPM 2 times a day; with each time 30 minutes and frequency of 2 minutes per cycle. The rehabilitative protocol for the control group was based on the postoperative TKA rehabilitation regime of the Orthopedics department of changzheng hospital. And knee ROM, knee function, knee pain degree and ability of daily life of all patients were measured at interval time.Results: Compared with the control group, the experimental group has better knee ROM and knee function. And there were no significant differences between the two groups in pain scores and tumidness of knees. On discharge day, Katz index of ADL of the experimental group was significantly lower than that of the control group.Conclusion: CPM applications play a positive role in promoting early recuperation of postoperative TKA patients, and could effectively improve patients'knee ROM, knee function and the activity ability of daily life within 26 weeks after operation. In addition, CPM applications in early rehabilitation phase do not increase or decrease pain and tumidness of postoperative TKA patients. |
