Abstract： Objective To comparatively analyze the effect of continuous adductor canal block (ACB) and femoral nerve block (FNB) analgesia on pain and early functional training after total knee arthroplasty (TKA). Methods A total of 76 patients undergoing TKA were divided into ACB group and FNB group by the random number table method. The numeric rating scale (NRS) and early functional training associated indicators in resting and active state were compared between the two groups at different time points, and adverse reactions during analgesia were statistically analyzed. Results At 2h, 6h, 12h, 24h and 48h after surgery, the NRS scores in resting and active state showed no significant differences between the two groups (P<0.05), and quadriceps femoris muscle strength of the affected limbs of the ACB group was significantly lower than that before surgery (P<0.05). 24h, 48h and 72h after surgery, the knee range of motion of the affected limb was significantly smaller than that before surgery (P<0.05). The quadriceps femoris muscle strength and knee range of motion of the affected limbs were better in the ACB group than the FNB group at different time points after surgery (P<0.05). Conclusion The analgesic effects and adverse reactions of continuous ACB and FNB are similar after TKA but the effect of continuous ACB on quadriceps femoris muscle strength is significantly less, and the knee range of motion is significant greater, which is good for the early functional training.
