Instabilités du genou

Knee instability is a subjective symptom that encompasses many anatomo-clinical situations. Patient's declarations, clinical examination, and x-ray pictures allow, most of the time, establishing precise diagnosis. More sophisticated investigations may be necessary secondarily, in the pre-operating context. When analysing the symptoms and for the determination of the lesion diagnosis, the practitioner has to put the instability in clinical context (patient questioning, clinical and paraclinical examination). The main diagnostic contexts that will be considered in the present chapter are those instabilities of ligament and meniscus origin and those of patellofemoral origin.
