The suspensory mechanism of the posterior part of the lateral meniscus is an anatomically complex structure which allows its mobility, essential to the kinematics of the knee. Damage to this structure (either through knee trauma or congenital abnormalities) can result in an instability of the lateral meniscus that may lead to lateral knee pain, locking sensations or lack of rotational control of the knee. Currently, there are no reliable clinical or imaging tests to identify this pathology and the diagnosis of lateral meniscus instability is often delayed or missed
The authors of this study propose a novel method for a quick and easy arthroscopic screening test (called the aspiration test) to help surgeons to identify this instability of the lateral meniscus
The description of this test is important in order to improve its diagnosis and to allow for complete anatomical repair when indicated.
