Comparative Study of Anterior Tibial Translation Measurement by Four Laximeters in Anterior Cruciate Ligament Ruptures

Comparative Study of Anterior Tibial Translation Measurement by Four Different Laximeters in Anterior Cruciate Ligament Ruptures

Actually, there are several laximeters for measuring anterior tibial translational in case of anterior cruciate ligament rupture. The most commonly used are telos, KT-1000, GnrB and Rolimeter. Results of these instrumented tests, which expressed in differential (millimeters values), have a bad correlation between them and so are not comparable in current literature. The aim of this study was to compare results of these tests and establish a ratio (pathologic knee laxity/ healthy knee laxity) to reduce differences between each instrumented test.
