Abstract:Objective To evaluate the efficacy of modified Le-maire anterolateral tenodesis combined with single-bundle reconstruction in patients with anterior cruciate ligament (ACL) injuries accompanied by high axial shift.Methods A total of 108 patients with ACL injuries accompanied by high axial shift, admitted to the 983rd Hospital of the Joint Logistics Support Force of the Chinese People's Liberation Army between October 2020 and March 2023, were included in the study. Patients were divided into two groups based on the surgical approach: 54 patients who underwent modified Le-maire anterolateral tenodesis combined with single-bundle reconstruction were included in the combined group, while 54 patients who underwent single-bundle reconstruction alone were included in the simple reconstruction group. Knee stability (knee axial shift test, KT-2000 side-to-side difference), knee function [Lysholm Knee Score, International Knee Documentation Committee (IKDC) subjective score], return to sport at the final follow-up (return to pre-injury activity level, time to return to sport, Tegner score), and incidence of complications were compared between the two groups.Results At the final follow-up, the combined group had a lower grade on the axial shift test than the simple reconstruction group (P < 0.05); the combined group also had a lower KT-2000 side-to-side difference at the final follow-up than the simple reconstruction group (P < 0.05). At the final follow-up, both the Lysholm Knee Score and the IKDC subjective score were higher in the combined group than in the simple reconstruction group (P < 0.05). At the final follow-up, the proportion of patients in the combined group who had returned to their pre-injury level of activity and their Tegner score were both higher than those in the simple reconstruction group, and the time to return to sport was shorter than in the simple reconstruction group (P < 0.05). There was no statistically significant difference in the overall incidence of complications between the combined group and the simple reconstruction group (P > 0.05).Conclusion Compared with isolated reconstruction, modified Le-maire anterolateral tenodesis combined with single-bundle reconstruction yields better outcomes for patients with ACL injuries accompanied by significant axial shift. This approach effectively restores knee stability and function, enables earlier and better return to sport, and does not increase the risk of postoperative complications.
