Chronic frontal instability   [read the french version]

Author :   Docteur Anne Thiescé

These instabilities can be painless but they lead to falls and collapsing, thus, prescribing the cessation of dancing.

They can be painful, accompanied by a transient jamming that can occur in any position.

These chronic instabilities can lead to a traumatic dislocation when X-rays show patellar or trochlear morphological anomalies and / or the misalignment of lower limbs such as a genu valgum or recurvatum and an external tibial hyper-rotation.

Treatment is based on a functional re-education combined with a proprioceptive re-education, for a minimum of 3 months.

This treatment can avoid acute luxation in the event of a bad jump landing or, even a minor trauma.
