Early continous passive motion with accelerated recovery of knee joint function after operation of distal femur fracture

Objective To study the effect of early continous passive motion(CPM) on knee joint function after operation of distal femur fracture and explore a pratical and effective method to accelerate function recovery of knee joint.Methods Open reduction and internal fixation with anatomical distal femur plate were used in distal femur fracture in all patients.In group CPM,CPM machine was used to exercise the knee joint in 24 hours after operation and lasted 10～14 days,then let the patients to exercise their knee joints by active flexion and stretch.In non-CPM group,let the patients to exercise their knee joints by active and passive flexion and stretch without CPM machine.The function of knee joints were evaluated at ten days and six weeks after operation.Results The function of knee joints in group CPM were significantly better than in non-CPM group.Conclusion Early continous knee joint passive notion after operation of distal femur fracture can accerate the recover of knee joint function.
