Abstract

Objective: To study the effect of continuous passive motion(CPM) after total knee replacement(TKR). Methods Ninteen patinents (24 knees) with TKR were randomly divided into 2 groups. The CPM group consisted of 11 patients (14 knees) and the non-CPM group consisted of 8 patients (10 knees). The patients of CPM group began CPM on the third postoperative day. The patients of non-CPM group had an identical treatment except CPM. Results After 2 weeks, the average degree of the knee active flexion in CPM group was 94.62 degrees which was more than that in non-CPM group. All patients could tolerate CPM and wound healing was not affected. Conclusion Knee flexion was increased significantly by CPM after TKR.
