    The arthroscopic Lachman test aids surgeons in identifying anterior cruciate ligament deficiency using standard arthroscopic views. This technique is valuable for confirming anterior laxity elimination after ligament reconstruction surgery.

    Area of Science:

    • Orthopedic Surgery
    • Sports Medicine
    • Arthroscopy

    Background:

    • Anterior cruciate ligament (ACL) deficiency is a common knee injury.
    • Accurate diagnosis is crucial for appropriate treatment and patient outcomes.
    • Standard clinical tests can sometimes yield false-negative results due to patient guarding or concurrent injuries.

    Purpose of the Study:

    • To describe the arthroscopic Lachman test as a method for diagnosing ACL deficiency.
    • To highlight the utility of the arthroscopic Lachman test in challenging diagnostic scenarios.
    • To evaluate its role in assessing the success of ACL reconstruction.

    Main Methods:

    • Utilizes familiar anatomic references during arthroscopic evaluation.
    • Performs a modified Lachman maneuver within the arthroscopic setting.

  • Assesses anterior tibial translation relative to the femur.

    • Main Results:

    • The arthroscopic Lachman test effectively identifies ACL deficiency.
    • It is particularly useful when physical examination is limited by guarding or meniscal pathology.
    • Post-reconstruction, it helps confirm the resolution of abnormal anterior laxity.

    Conclusions:

    • The arthroscopic Lachman test is a valuable adjunct for diagnosing ACL deficiency.
    • It enhances diagnostic accuracy in cases with suspected false-negative physical exams.
    • It serves as an effective tool for post-operative assessment of ACL reconstruction outcomes.
