Abstract：【Objective】To compare the effects of ultrasound-guided continuous femoral nerve block (CFNB) and adductor canal block (CACB) in analgesia after total knee arthroplasty (TKA).【Methods】A total of 86 patients who underwent unilateral TKA were randomly and equally divided into two groups. Patients undergoing ultrasound-guided CFNB on operation side were included as the CFNB group while patients undergoing ultrasound-guided CACB were included as the CACB group.The postoperative analgesic effects were compared between the two groups.【Results】There was no significant difference in heart rate (HR), mean arterial pressure (MAP) and oxygen saturation (SpO2) between the two groups at all time points (P>0.05). The resting-state and motion-state VAS scores showed a firstly increasing and then decreasing trend (P>0.05). There was no significant difference in the above-mentioned indices at all time points (P>0.05). The quadriceps femoris strength of two groups showed a gradually increasing trend (P<0.05). At time points 2, 6, 12 and 24hrs after operation, the scores in CACB group were significantly higher than those in CFNB group (P<0.05). The knee joint activity of two groups showed a gradually increasing trend (P<0.05). On the 1st, 3rd and 7th days after operation, the knee joint activities of CACB group were significantly better than those of CFNB group (P<0.05). There was no significant difference between the two groups in the number of medication for patient-controlled analgesia and the use of pethidine (P>0.05). The incidence of adverse reactions of opioid agents in the two group did not show any significant difference (P>0.05).【Conclusion】After TKA, the analgesic effects of CACB and CFNB are similar. However, the effect of CACB on quadriceps femoris strength and knee joint activity is less, which is slightly more conducive to postoperative rehabilitation.
