The number of patients requiring a total knee arthroplasty (TKA) is increasing and postoperative care is an important factor for the recovery of knee function. It is discussed controversially, if the benefits of controlled active motion (CAM) therapies are comparable to continuous passive motion (CPM) therapies.
Comparison of postoperative outcomes using a device in CAM and CPM settings, in addition to standard physiotherapeutical exercises immediately after TKA.
TKA patients were randomized to either CAM or CPM therapy performed with an identical device (ARTROMOT® ACTIVE-K, Ormed GmbH). All patients received an additional physiotherapeutic program. Pain, knee associated problems (KOOS), active range of motion (ROM), and adverse events were documented before surgery, during the stationary stay and after an outpatient period.
We included 50 patients (70 ± 8 years). During the postoperative period, KOOS scales improved significantly in both groups, but the CAM group showed a significantly better improvement of pain and quality of life scale. Furthermore, postoperative course of pain intensity and knee flexion was significantly better in the CAM group.
CAM and CPM lead to significant improvements after TKA, but CAM shows better results in terms of flexion, pain and quality of life.
需要进行全膝关节置换术（TKA）的患者数量正在增加，术后护理是膝关节功能恢复的重要因素。对于控制主动运动（CAM）疗法的益处是否与持续被动运动（CPM）疗法相当，存在争议。
除了TKA术后立即进行标准物理治疗锻炼外，比较在CAM和CPM环境中使用一种设备的术后结果。
TKA患者被随机分为接受使用相同设备（ARTROMOT® ACTIVE-K，Ormed GmbH）进行的CAM或CPM治疗。所有患者均接受额外的物理治疗方案。在手术前、住院期间和门诊期后记录疼痛、膝关节相关问题（KOOS）、主动活动范围（ROM）和不良事件。
我们纳入了50名患者（70±8岁）。在术后期间，两组的KOOS量表均有显著改善，但CAM组在疼痛和生活质量量表方面的改善明显更好。此外，CAM组术后疼痛强度和膝关节屈曲的进程明显更好。
TKA术后CAM和CPM均能带来显著改善，但CAM在屈曲、疼痛和生活质量方面显示出更好的结果。
