Clinical Outcomes of Combined Anterior Cruciate Ligament Reconstruction and Lateral Extra-articular Tenodesis Using the Coker-Arnold Technique: A Retrospective Case Series of 328 Patients With a 72-Month Follow-up.

The American journal of sports medicine·2026

Revision anterior cruciate ligament (ACL) reconstruction using contralateral doubled semitendinosus and gracilis tendon (DGST) grafts is a viable surgical option. This study found favorable patient outcomes and stability following this technique.

Area of Science:

  • Orthopedic surgery
  • Sports medicine
  • Biomechanical research

Background:

  • Primary anterior cruciate ligament (ACL) reconstructions are increasing, leading to a rise in revision surgeries.
  • Evaluating graft options for revision ACL reconstruction is crucial for restoring knee function.

Purpose of the Study:

  • To assess the efficacy of using contralateral doubled semitendinosus and gracilis tendon (DGST) grafts for revision ACL reconstruction.
  • To determine the functional and clinical outcomes of revision ACL reconstruction with hamstring tendons.

Main Methods:

  • A cohort of twelve patients undergoing revision ACL reconstruction with hamstring tendons was evaluated.
  • Follow-up included subjective assessments (Tegner, Lysholm, IKDC 2000 scores), objective physical examinations (Lachman, pivot shift tests), and KT-1000 arthrometric evaluation.

  • Radiographic examination was performed to assess for osteoarthritis.

    • Main Results:

    • Patients reported high functional scores: median Tegner 5.5, mean Lysholm 95, and mean IKDC 2000 95.4.
    • Objective testing showed good knee stability, with most patients having negative Lachman and minimal pivot shift and KT-1000 side-to-side differences.
    • Twenty-five percent of patients showed early signs of osteoarthritis.

    Conclusions:

    • Contralateral doubled semitendinosus and gracilis tendon (DGST) grafts are a suitable option for revision ACL reconstruction.
    • This technique demonstrates positive functional outcomes and knee stability in patients with failed primary ACL reconstruction.
