- Abstract: Objective To investigate the application value of arthroscopic three-approach combined with elliptical tunnel technique in anterior cruciate ligament(ACL)reconstruction.Methods A prospective analysis was conducted on 104 patients with ACL injury admitted to our hospital.They were randomly divided into the observation group and the control group according to a random number table method,with 52 cases in each group.All patients in both groups underwent ACL reconstruction.The patients in the observation group were treated with the arthroscopic three-approach combined with elliptical tunnel technique,while the patients in the control group were treated with the traditional anteromedial approach and elliptical tunnel technique.The surgical related indicators,parameters of postoperative bone tunnel positioning,postoperative graft maturation,knee stability(Lachman test),Lysholm score of knee function,and complications of patients were compared between the two groups.Results The time of getting out of bed with crutches,time of walking without crutches and recovery time of patients in the observation group were shorter than those in the control group(P<0.05).The A/B value of patients in the observation group was greater than that in the control group,and the a/c and α were smaller than those in the control group(P<0.05).The signal/noise quotient(SNQ)of the proximal,middle,and distal grafts 6 and 12 months after surgery of patients in the observation group were lower than those in the control group(P<0.05).At 6 months postoperatively,the knee stability of patients in the observation group was better than that in the control group,and the Lysholm score of knee function was higher than that in the control group(P<0.05).There was no significant difference in the incidence of postoperative complications between the two groups(P>0.05).Conclusion Arthroscopic three-approach combined with elliptical tunnel technique can improve the morphology of bone tunnel,promote graft maturation,shorten postoperative recovery process,and improve knee function in ACL reconstruction,with high safety.
