Clinical Trial Summary

Anterior cruciate ligament (ACL) is a common pathology (37 000 operations in 2006, nearly 43 000 in 2012 in France) justifying more and more operating indications in younger and younger patients. 70-80% of ACL ruptures occur without contact, which makes it a major public health interest because of its frequency and accessibility in terms of prevention.

The place of isokinetic assessment is important pre and postoperatively so that it has become systematic.

Description:

The main risk factors for known ACL lesions are female gender, pivotal sports, neuromuscular deficits, proprioceptive, hormonal, morphological deficits ... Moreover, there is also an increase in the number of contralateral fractures in patients who had a ligamentoplasty. There are many articles on the ACL pathology but unequal on the potential risk factors. The only proven risk factor for contralateral rupture is the age of the first episode; the female sex also seems to be important in some studies but remains more controversial. However, many factors have been studied: the intensity of the sport, the sex, the operative technique of ligamentoplasty, the operating duration, the duration of recovery of the sports activity, the level of recovery (of this sporting activity ) ...

Isokinetics is used to measure the peak of strength of quadriceps and hamstrings, in concentric or eccentric, at slow and fast speed and to determine a hamstring / quadriceps ratio to highlight a deficit or imbalance.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Evaluation of relative hamstrings deficiency versus quadriceps expressed by a concentric hamstrings/quadriceps ratio	Isokineticism makes it possible to measure the peak of force of quadriceps and hamstrings. Concentric hamstrings/quadriceps ratio in isokinetic is calculated to detect a relative deficiency if it is below threshold values of 55% at 60 °/s slow speed, or 65% at 180 °/s fast speed.	At inclusion
Secondary	Investigating whether a lack of recruitment of hamstring at fast speed is a potential risk factor for ACL rupture, by evaluating hamstrings/quadriceps ratio in isokinetics.	The lack of recruitment of the hamstrings when increasing speed is defined as normal ratios of peaks of force at the two speeds in isokinetic, but with an increase of the ratio hamstrings/Quadriceps in concentric at fast speed lower than 10%, with reference to the value of the ratio hamstrings/Quadriceps at slow speed.
