    What is the KT 1000 arthrometer?

    KT 1000

    KT 1000

    During the 1970's, USA's orthopaedic community was the first to witness the arrival of the now famous and appreciated KT-1000 arthrometer. This device quickly became the reference in its field of work as it allowed for the first time an objective assessment of the anterior cruciate ligament (ACL) without having to perform an invasive surgery.

    Following the good reception of this medical device and computer technology being more and more present around its wide community of users, the company eventually created a new computerized version of the device: the KT-2000.

    During the decades following their creation, both devices maintained an excellent reputation and were worldwidely sold but like any piece of technology nowadays, time passes and production cessed since 2012.

    DYNEELAX & GNRB : The new KT-1000/KT-2000

    GNRB arthrometer

    GNRB arthrometer

    In 2007, Genourob's founders Dr Henri Robert and Mr Stéphane Nouveau had the idea of creating a new and innovating arthrometer destined to assess knee laxity. Unlike any other medical device already present on the market, the device they had imagined would be completely automated to assure great precision while assessing the ligamentous structures of the knee. Therefore was created the GNRB, the world's first automated arthrometer for anterior cruciate ligament (ACL) assessment.

    The technique used by the GNRB resembles a lot the one applied by the KT-1000/KT-2000 as it automates the drawer test to evaluate knee laxity. Consequently, the GNRB was often compared to the KT-1000 and seen as its follow up but the additional parameters present on the newer GNRB made its assessment technique much more precise and reproducible.

    Dyneelax vs KT1000

    Further-more, as of 2020 an even more accurate arthrometer has been released, the DYNEELAX. This arthrometer lets the user perform tibial translation and tibial rotation on the knee with a single device to assess knee stability. This is indeed a real step forward in the field of knee arthrometry as before 2 separate products were required. Reproducibility & accuracy are hence increased but most importantly, a complete knee ligament check-up may be performed in a short duration of time.

    Use Pre-surgery Pre-Surgery and Post-surgery Pre-Surgery and Post-surgery

    The post surgical use is perhaps the biggest asset of the GNRB & DYNEELAX in this chart as it is possible to assess the ACL graft not long after the surgery. This is indeed a characteristic that was not available with the KT-1000 because the risk of applying high stress on the graft is too high, risk that is not present while running a test with a GNRB and DYNEELAX as the forces applied on the tibia a controlled.
