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.

Comparison of anterior laxity measurement between pathologic and healthy knees.
Collect and compare differential values of anterior laxity between pathologic and healthy knee obtained by four different laximeters (Telos, KT-1000, GnrB and Rolimeter)
Time frame: 18 months
Sensivity and specificity of each instrument
Determine sensivity and specificity of each instrument test to highlight a cruciate ligament rupture and find the better test. Evaluations are using the 4 following devices: Telos ©, KT-1000 ©, Rolimeter, and GnrB.
Time frame: 18 months
Correlation between the f4 laximeters results
Estimate if correlation between two results increase discriminating capacity in comparison with the reference.
Time frame: 18 months
Value of the ratio : pathologic (anterior knee laxity) versus healthy knee
Compare ratio pathologic versus healthy knee obtained with each instrument to determine a possible harmonization of measurements
Time frame: 18 months
