What does Recurvatum mean?
(rē-kŭr-vā′tŭm) Backward bowing. At the knee, it is called genu recurvatum; at the elbow, it is called cubital recurvatum.
What causes genu recurvatum?
Genu recurvatum is a term that is used when one hyperextends their knee. Knee hyperextension can be caused by several causes. These include muscle weakness, especially of the muscles in the top of the thigh (quadriceps), it can be due to injury, or it can occur due to the shape of one’s bones at their knee.
What is genu recurvatum?
Genu recurvatum describes the malalignment or deformity of the knee joint with extension beyond neutral (i.e. hyperextension).
Why do some people’s knees bend backwards?
Hyperextension of the knees happens because some people have loose ligaments and tendons around the knee joint. Often these people have looseness globally. They also may have pelvic misalignment like anterior pelvic tilt, posterior pelvic tilt or hyperextension of the the hip joint (or sway back).
How much knee hyperextension is normal?
A certain degree of hyperextension is normal, with studies citing a mean of 5 degrees of hyperextension in males and 6 degrees in females. Simply restoring knee range of motion to an arbitrary 0 degrees is not advantageous.
Is Genu Recurvatum rare?
Genu recurvatum loosely translates as “backward-bending knee.” It is also known as congenital dislocation of the knee (CDK) or congenital dislocation of the patella (CDP), and sometimes as congenital hyperextension. CDK is a rare condition with an incidence rate of approximately 1 per 100,000 live births.
Is genu recurvatum normal?
The normal range of motion (ROM) of the knee joint is from 0 to 135 degrees in an adult. Full knee extension should be no more than 10 degrees. In genu recurvatum, normal extension is increased….

Is Genu Recurvatum genetic?
Congenital genu recurvatum (CGR) is an extremely rare condition observed at birth. It is associated with, among other malformations, genetic entities such as the Larsen syndrome. When CGR is isolated, orthopedic treatment will usually lead to a good functional prognosis.
What is the external rotation Recurvatum test?
The external rotation recurvatum test is the first test performed to evaluate a patient with potential posterolateral rotatory instability. In this test, the examiner determines if there is an increased amount of knee hyperextension compared to the contralateral side.
Quelle est la meilleure orthèse de genou?
Dans les formes plus sévères, une orthèse de genou peut être la solution la mieux adaptée pour traiter le genu recurvatum . Cette orthèse permet de contrôler l’amplitude articulaire de genou dans les mouvements de flexion et d’extension.
Comment se traiter une arthrose du genou?
Il est très fréquent. Le traitement consiste en l’association d’exercices musculaires, en particulier la marche sur la pointe des pieds, de la vitaminothérapie et des rayons ultraviolets. La déformation peut persister à l’âge adulte et être à l’origine d’une arthrose du genou.
Est-ce que l’arthrose du genou persisté depuis l’enfance?
À l’âge adulte, il arrive que l’arthrose du genou soit causée par un genou recurvatum ayant persisté depuis l’enfance. Comme la déformation provoque un déplacement des forces et des points de pression dans l’articulation, des douleurs et des raideurs sont ressenties, dues à la détérioration des cartilages.
