Introduction: The traditional CPM rehabilitation mode and the new CMB rehabilitation mode were analyzed and compared in detail, in order to improve the methods of postoperative functional rehabilitation of orthopedic TKA patients.

Materials and methods: A total of 194 patients who underwent TKA in our hospital from October 2019 to June 2021 were divided into control group (CPM training) and experimental group (CMB training) according to different training methods of preoperative education. ADL score, HSS score, and NRS score were performed at 1, 3, 5 and 7 days after operation, and the measured value of knee joint range of motion, muscle strength and muscle bundle diameter were recorded, and the postoperative adverse reactions of patients were counted.

Results: The ADL score and HSS knee function score of patients in hospital for 7 days showed that the activities of daily living and knee rehabilitation scale scores of patients in the experimental group were higher than those in the control group at different times from 1 to 7 days after operation, and the scores of patients in the experimental group were significantly higher than those in the control group at 5 and 7 days after operation. The average NRS scores of patients in the experimental group were significantly lower than those in the control group 3-7 days after operation. The ROM of knee joint activity of patients in the experimental group was higher than that in the control group within 7 days after operation. The ROM score of average knee joint activity of patients in the experimental group was significantly higher than that in the control group at 5 and 7 days after operation. The muscle strength test values of the experimental group were higher than those of the control group, but the difference was not significant. There was no significant difference in the number of four complications between the two groups. The total incidence of the control group was higher than that of the experimental group, but the degree of difference did not constitute statistical significance.

Conclusion: The training method of CMB can provide some help for the rehabilitation of patients after knee replacement, and has a certain reference value for their postoperative functional recovery. The new training mode and rehabilitation equipment are worth promoting.
