Seventy-five of 150 consecutive patients who underwent total knee arthroplasty had routine physiotherapy and seventy-five had continuous passive motion of the lower limb that had been operated on as well as routine physiotherapy. A pulmonary embolus did not develop in any patient, but about 40 per cent had thrombosis in the veins of the calf, whether passive motion had been administered or not. Radiographically, the deep-vein thrombosis was seen to extend into or proximal to the popliteal vessel in 5 per cent of the patients in each group. Sex, age, obesity, or a history of hypertension or diabetes did not influence the incidence of venous thrombosis, but there was a higher incidence in patients in whom cement was used for fixation of the total knee components, irrespective of the use of continuous passive motion of the limb.
150例接受全膝关节置换术的连续患者中，75例接受常规物理治疗，75例在接受常规物理治疗的同时，对手术侧下肢进行持续被动运动。所有患者均未发生肺栓塞，但无论是否进行被动运动，约40%的患者小腿静脉出现血栓形成。影像学检查显示，每组5%的患者深静脉血栓延伸至腘血管或其近端。性别、年龄、肥胖、高血压或糖尿病病史均不影响静脉血栓形成的发生率，但无论是否使用肢体持续被动运动，使用骨水泥固定全膝关节组件的患者静脉血栓形成发生率较高。
