Summary

Double-bundle anterior cruciate ligament (ACL) reconstruction using a double-incision technique improves knee stability and reduces pivot shift compared to single-bundle methods. This approach enhances patient outcomes for ACL injuries.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Biomechanical Engineering

Background:

  • Anterior cruciate ligament (ACL) injuries are common, affecting knee stability and function.
  • Replicating the native ACL's dual bundles (anteromedial and posterolateral) is crucial for optimal reconstruction.
  • Current techniques aim to restore knee stability and patient satisfaction after ACL tears.

Purpose of the Study:

  • To compare the clinical and functional outcomes of single-bundle versus double-bundle ACL reconstruction techniques.
  • To evaluate the efficacy of single-incision transtibial and double-incision outside-in techniques for double-bundle ACL reconstruction.
  • To assess improvements in knee stability and reduction of residual pivot shift.

Main Methods:

  • Prospective study of 75 patients with isolated ACL lesions, divided into three groups (n=25 each).

Arthroscopic Excision of Posterior Cruciate Ligament Cysts Using a Double Posteromedial Approach

Published on: October 20, 2023

  • Group I: Single-bundle, single-incision transtibial ACL reconstruction.
  • Groups II & III: Double-bundle reconstruction using single-incision transtibial or double-incision outside-in techniques, respectively.
  • Evaluations included subjective IKDC, KOOS, objective IKDC, and KT-1000 measurements at minimum 2-year follow-up.

    • Main Results:

    • KT-1000 side-to-side difference was 2.4 mm (Group I), 1.6 mm (Group II), and 1.4 mm (Group III).
    • The double-bundle, double-incision outside-in technique (Group III) showed improved anteroposterior stability.
    • Fewer patients in Group III experienced a positive pivot shift compared to Group I.

    Conclusions:

    • Double-bundle ACL reconstruction, particularly the double-incision outside-in technique, offers superior anteroposterior stability.
    • This technique effectively reduces residual pivot shift, enhancing functional outcomes after ACL reconstruction.
    • The double-incision outside-in method may provide a more anatomical and functional restoration of the ACL.
