Brief 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.

Detailed 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.
