    KT-1000 / KT-2000 / GNRB COMPARISON

    This article shows the main differences between the KT-1000, KT-2000, GNRB and DYNEELAX arthrometers: Four medical devices designed to assess knee ACL laxity

    KT 2000

    KT 2000

    The DYNEELAX is the most recent arthrometer released on the market (2020). It shares similar characteristics with the KT 1000, KT 2000 but is more precise while assessing knee laxity as it provides an objective evaluation of knee stability resulting from the automated anterior drawer test it performs. In addition, the DYNEELAX also offer rotation instability analysis.

    Reproducibility of the tests is also an attribute of this device as several parameters incorporated in this tool enable medical practitioners to use the device in the pre / post surgery phases of the patient's medical management.

    Pre-Surgery and Post-surgery

    After carefully analyzing this tables chart, we can deduce that the post surgical use of the GNRB and DYNEELAX may represent the biggest asset of these arthrometers as it is possible to follow the state of the ACL graft.

    This characteristic makes this device essential during ACL rehab as it practically guarantees the clinician that knee stability will be attained at some point since personnalized rehabilitation becomes possible for each unique patient.
