Effect of Continuous Passive Motion Training on the Range of Motion of Knee Joint after Operation of Knee Fractures

Objective: To investigate the effect of continuous passive motion(CPM) training on the knee joint range of motion after operation of knee fractures. Methods: Forty seven cases of knee joint fractures were divided into 4 groups randomly. After all patients were subjected to conventional physical therapy, the patients in Gl, G2 and G3 groups received continuous passive motion training on the first,second and third week postoperatively for 4 weeks respectively. Results: On the sixth week after treatment, the postoperative knee joint range of motion in G0, G1, G2 and G3 groups was (64±5)°, (89 ±7)°, (73 ±4)° and (68 ±3)° respectively. There was significant difference among the 4 groups. Conclusion: Early applied CPM training can quickly promote the rehabilitation of knee function.
