    The automated dynamic laximetry for a new approach in the examination of the ligament function

    The LDA® allows measurement and calculation of new parameters to enable sometimes complex radiological examinations of the knee ligament function.

    The LDA® test is an indispensable complement to medical imaging in the exploration of the ACL. It allows a dynamic vision for the registration of ligament resistance curves.

    The GNRB Radio is specially designed for a rational use in a radiology practice

    Simple and fast to use, comfortable for the patient (laying on the radiology table), the LDA® test is performed within minutes during the radiological examination.

    The GNRB Radio features a 5 seconds lock function of the tibial translation, in the up position, allowing to operate an XRay image.

    In addition to the technical innovations the GNRB Radio offers an integrated biofeedback system (option) to detect hamstrings muscle contractions, avoiding false-negatives.

    A patented method of measurement

    The Lachmann’s test is fully automated with the GNRB Radio.

    The fixation parameters of ankle and tibia are saved. The LDA® software synthesis and compares the measures taken at both knees immediately by measuring the slopes of the ligament resistance curves of the ACL (Innovation Genourob)

    Shown example: Preoperative control
    Δ 134 = 6 mm, Δ P2 = 2
    Complete Rupture
    Objectification of a clinical Lachmann-test


    The GNRBs are the only automated dynamic laximeters, where test results can be integrated into the patient data-management system
    of the radiology practice.
    The result of the LDA® test is immediately printed and joins the radiological examination in the file of the patient. Export in different formats is possible.
