Objective To investigate the impact of adductor canal block(ACB)in combination with popliteal plexus block(PPB)on patients undergoing arthroscopic anterior cruciate ligament reconstruction(ACLR).Methods Patients who underwent primary unilateral ACLR treatment at our hospital between March 2022 and November 2023 were recruited as the research subjects.They were randomly allocated into the ACB group(n=43 cases)and the combined PPB group(n=47 cases)using a coin-toss method.Patients in the ACB group received ACB,while those in the combined PPB group received ACB in conjunction with PPB.The pain intensity,analgesic effect,adverse reactions,and postoperative status following ACLR were compared between the two groups.Results The Visual Analogue Scale(VAS)scores of the combined PPB group were significantly lower than those of the ACB group at 4 hours,8 hours,12 hours,24 hours,and 48 hours post ACLR(P<0.05).Repeated measures analysis of variance of VAS scores in the resting and active exercise states of ACLR patients in the two groups revealed that the group effect had F-values of 162.052/142.173 and P-values of 0.000/0.000,the time effect had F-values of 74.223/65.515 and P-values of 0.000/0.000,and the interaction effect had an f-value of 4.707/.The cumulative dose of sufentanil,the frequency of postoperative analgesia,and the proportion of posterior knee pain in the combined PPB group were all lower than those in the ACB group(P<0.05).There was no significant difference in adverse reactions between the ACB group and the combined PPB group(P>0.05).The hospitalization duration and the time to achieve active straight leg raise in the combined PPB group were shorter than those in the ACB group,while the analgesic satisfac-tion score was higher than that in the ACB group(P<0.05).Conclusion The combination of ACB and PPB in ACLR can effectively alleviate postoperative pain,reduce the requirements for sufentanil and analgesic interven-tions,enhance patient satisfaction,shorten the hospitalization period and the time to achieve active straight leg raise,and promote early patient recovery without increasing the risk of adverse reactions.
