Abstract: Objective To investigate the efficacy of muscle energy technology for ultra-early rehabilitation after surgery for tibial plateau fractures. Methods A retrospective analysis was conducted of the data of 24 patients undergoing tibial plateau fracture surgery in the Department of Orthopedics, Tongji Hospital Affiliated to Tongji University from 2020 to 2021. All patients underwent open reduction and internal fixation with steel plate, and functional rehabilitation exercise 3-4 d after surgery. The observation group （12 cases） was treated with muscle energy technique （MET） combined with continuous passive motion （CPM） training, and the control group （12 cases） was treated with CPM training alone. The length of hospitalization was generally 7-10 d. The VAS score and HSS knee score before and after treatment were compared between the two groups. Results After the treatment, the wounds of the patients in both groups healed well, the postoperative fixed position was good, and the physical condition was stable. There was no significant difference in VAS scores of the two groups before treatment （P>0.05）, and the observation group’s VAS score was lower than the control group’s after treatment （P<0.05）. There was no significant difference in HSS scores between the two groups before treatment （P>0.05）, while after treatment, the HSS score of the observation group was higher than that of the control group （P<0.05）. Conclusion MET has a significant effect on ultra-early functional recovery after tibial plateau fracture surgery, such as effectively reduced postoperative pain, improved knee mobility, and accelerated rehabilitation.
