Abstract:Objective To investigate the analgesic effect of adductor canal block and femoral nerve block after total knee arthroplasty. Methods To analyze the clinical data of 80 total knee replacement patients admitted to Changhai Hospital, Naval Medical University from February 2016 to October 2016, there were 40 patients in adductor duct block group and 40 patients in femoral nerve block group. The rest pain digital score scale (NRS), active pain NRS and quadriceps femoris muscle strength of the two groups of total knee arthroplasty patients at different time points after surgery were observed, and the knee range of motion of total knee arthroplasty patients of the two groups at different time points after surgery were observed. Results There was no significant difference in NRS score of resting pain and NRS score of active pain between the two groups at different time points after total knee replacement (P > 0.05). The muscle strength grades of quadriceps femoris in the adductor duct block group were higher than that in the femoral nerve block group at 2, 4, 8, 12, 24 and 48 h after surgery. The NRS score of resting pain and NRS score of active pain in the two groups decreased gradually with time extension, and the differences were statistically significant (P < 0.05). There was no statistically significant difference in quadriceps femoris muscle strength grading between the two groups 72 h after surgery (P > 0.05). The quadriceps femoris muscle strength grading increased gradually with the extension of time in both groups, and the difference was statistically significant (P < 0.05). The ranges of motion of the knee joint in the adductor duct group 24, 48 and 72 h after surgery were higher than those in the femoral nerve block group, and the differences were statistically significant (P < 0.05). Conclusion Adductor canal block and femoral nerve block have the same analgesic effect after total knee arthroplasty, but adductor canal block patients are superior to femoral nerve block in postoperative muscle strength grade of quadriceps femoris and range of motion of knee joint.
