BACKGROUND: Early rehabilitation training can improve the knee function to maximal extent after total knee arthroplasty (TKA). OBJECTIVE: To acknowledge the difference between controlled active motion and continuous passive motion effects on function rehabilitation after TKA. METHODS: 226 patients who underwent unilateral TKA were divided randomly into controlled active motion group and continuous passive motion group. Patient's general condition, range of motion (ROM), visual analogue scale (VAS) score, knee society score (KSS) function score were recorded at 1.5, 3, 6 months postoperatively. RESULTS AND CONCLUSION: At 3 months postoperatively, the KSS score in the controlled active motion group was superior to that in the continuous passive motion group; at 6 months postoperatively, there was no significant difference in the KSS score between the two groups. At 1.5 and 3 months after TKA, the ROM in the controlled active motion group was better than that in the continuous passive motion group; while, at 6 months, no significant difference was shown between the two groups. Controlled active motion can promote the function rehabilitation after TKA.
