Abstract：Objective: To explore the application of chloroprocaine given for femoral nerve block and its effect on rehabilitation exercises after total knee arthroplasty. Methods: From September 2017 to December 2018, 60 patients who had unilateral knee surgery with symptoms of the contralateral knee joint were selected in the Second Affiliated Hospital & Yuying Children’s Hospital of Wenzhou Medical University. Patients were randomly divided into two groups receiving 1% chloroprocaine 0.2 mL/kg (group C) or 0.9% sodium chloride solution 0.2 mL/kg (group NS). All patients underwent femoral nerve catheterization before surgery, and began knee functional exercises 48 h after surgery, 3 times a day for a total of 4 days. Drugs were administered to block femoral nerve 10 min before training. The NRS scores, maximum range of motion (ROM) of the third exercise every day before and after administration were recorded, as well as the NRS scores, maximum ROM, the training satisfaction and AKS scores on day 7 after surgery. Results: In group NS, there was no significant difference in ROM and NRS scores before and after the third administration every day on day 3-6 after surgery (P>0.05), but in group C, the ROM after the third administration every day on day 3-6 after surgery increased significantly compared with those before administration (P<0.01), while the NRS scores decreased apparently (P<0.01). ROM of group C on day 6 before administration, ROM on day 7 and training satisfaction were all significantly better than that of group NS(P<0.01). There was no significant difference in NRS and AKS scores between two groups on day
7 after surgery (P>0.05). Conclusion: 1% chloropprocaine 0.2 mL/kg given for femoral nerve block can alleviate the pain caused by early rehabilitation exercises after total knee arthroplasty, and improve the postoperative range of joint motion as well as the training satisfaction of the patients.
