Continuous passive motion (CPM) is commonly used as a postoperative rehabilitation treatment, along with physical therapy, for postoperative knee rehabilitation. However, the comparison between the two in terms of efficacy in postoperative knee replacement recovery is unclear.
To compare efficacy and safety of combined CPM versus physical therapy alone in postoperative rehabilitation after knee arthroplasty.
PubMed, Embase, and Web of Science databases were used to retrieve and access clinical studies on the efficacy of CPM compared with physical therapy. Review Manager software was used for study publication bias assessment and data analysis based on inclusion criteria.
A total of 6 articles covering 557 patients were included in the study. In terms of range of motion (ROM), passive knee flexion was similar between CPM and physical therapy (PT) (WMD, - 0.17; 95% CI, - 0.98-0.64; p = 0.68). At long-term follow-up, passive knee extension was similar between CPM and physical therapy (PT) (WMD, - 0.28; 95% CI, - 1.47 to - 0.92; I = 65%, p =0.65). In addition, CPM generates significantly higher in length of stay (WMD, 0.50; 95% CI, - 0.31 to 0.69; I = 3%, p < 0.001). CPM generates significantly higher treatment costs and incurs more care costs relative to physical therapy.
Compared to PT, combined with CPM failed to significantly improve ROM of the knees and patient's satisfaction. In addition, CPM treatment significantly increased the cost of hospitalization.
持续被动运动（CPM）通常与物理治疗一起作为术后康复治疗，用于膝关节置换术后康复。然而，CPM 在膝关节置换术后恢复方面的疗效与物理治疗的比较尚不清楚。
比较 CPM 联合治疗与单纯物理治疗在膝关节置换术后康复中的疗效和安全性。
使用 PubMed、Embase 和 Web of Science 数据库检索并获取关于 CPM 与物理治疗疗效比较的临床研究。根据纳入标准，使用 Review Manager 软件评估研究的发表偏倚并进行数据分析。
共有 6 篇文章涵盖 557 名患者纳入研究。在关节活动度（ROM）方面，CPM 与物理治疗（PT）的被动膝关节屈曲相似（WMD，-0.17；95%CI，-0.98 至 0.64；p = 0.68）。在长期随访中，CPM 与物理治疗（PT）的被动膝关节伸展相似（WMD，-0.28；95%CI，-1.47 至-0.92；I = 65%，p = 0.65）。此外，CPM 可显著延长住院时间（WMD，0.50；95%CI，-0.31 至 0.69；I = 3%，p < 0.001）。与物理治疗相比，CPM 治疗产生的治疗费用更高，护理费用也更高。
与 PT 相比，CPM 联合治疗并未显著改善膝关节 ROM 和患者满意度。此外，CPM 治疗显著增加了住院费用。
