  • Title: [The knee arthrometer KT-1000: value of instrumental measurement in diagnosis of complex anterior knee instability].

    Abstract:
    Clinical examination is the most accurate means of determining cruciate ligament integrity in the initial evaluation. In the case of a rupture of the anterior cruciate ligament the Lachman test has a high diagnostic accuracy, especially if the end point is absent. The Knee Arthrometer KT-1000 is a useful tool, as it is easy and fast to handle by an experienced examiner. Supplementary to noninvasive diagnostical methods it improves the confidence in clinical diagnosis. However, the importance of instrumental measurement should not be overrated even though reproducible results can be obtained. To compare the results of different studies the design has to be very similar. Although the examination conditions in this study were very homogeneous, a systematic mistake was produced. The average value of tibial displacement was significantly higher for the left knee. Data, obtained retrospectively in clinical practice, should not be used to scientifically document the results of therapeutic procedures.
