In plain words

What the trial is, and whether it could suit you

Rupture of the anterior cruciate ligament (ACL) is a frequent and disabling injury in pivot sports, leading to knee laxity and instability, reduced performance and an increased risk of early osteoarthritis. The risk is 2 to 8 times higher in women, linked to greater ligament laxity and a different quadriceps/hamstring muscle ratio post-puberty. To assess knee laxity and the degree of ligament damage, anterior tibial translation (of the tibia below the femur) is usually measured. This translation is symmetrical and varies between 3 and 10 mm depending on the individual (natural laxity). It is increased in cases of ACL damage. Measuring tibial rotation is also of interest in this context. Studies show that the ACL plays a crucial role in controlling internal and external tibial rotation, especially during low-flexion movements (between 10° and 30°). ACL rupture also significantly increas
