Abstract:
Objective To compare the clinical results of navigation-assisted single-bundle and double-bundle technique in anterior cruciate ligament (ACL) reconstruction.Methods A retrospective cohort study was designed and 57 patients with ACL injury in one knee were recruited for navigation-assisted ACL reconstruction.Twenty-nine patients were assigned to single-bundle reconstruction group and 28 to doublebundle reconstruction group.Preoperatively,there is no significant difference in International Knee Documentation Committee (IKDC) knee scores,KT-1000 and pivot-shift test results between two groups.Results The average follow-up periods were 47.1 months for single-bundle group and 36.2 months for double-bundle group.Stability result of the KT-1000 measurement was improved from (7.7±2.1) mm preoperatively to (1.6±5.1) mm at the last follow-up for single-bundle group,and from (7.9±3.7) mm to (2.2±3.0) mm for doublebundle group.KT-1000 measurements and pivot-shift tests at final follow-up failed to reveal any significant intergroup differences (P＞0.05).The IKDC grades in the single-bundle group were significantly better than those in double-bundle group (P＜0.05) at final follow-up.Second-look arthroscopies were performed in 10 patients in single-bundle group and 28 patients in double-bundle group.For 10 patients in single-bundle group,the arthroscopy showed the implants were continued with good tension.For double-bundle group,the arthroscopic findings revealed that posterolateral (PL) bundle was visible with good tension in 28.6％ of patients,PL bundle was visible but loose in 53.6％ and PL bundle was invisible in the other 17.8％ patients.Conclusion The navigation-assisted single-bundle and double-bundle ACL reconstruction produces are similar in terms of postoperative stability of knee.However,compared with double-bundle technique,the single-bundle technique can obtain better IKDC grades.
