What is another term for hyperextension of the knee?
Hyperextension of the knee, also known as “genu recurvatum” occurs when the leg excessively straightens at the knee joint, putting stress on the knee structures and the back of the knee joint.
What contributes to genu recurvatum?
Causes of genu recurvatum included physeal arrest; soft tissue laxity; and complications related to fractures, such as prolonged immobilization and malalignment.
What muscles are weak in 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 hyperextension of the knee?
A hyperextended knee occurs when the knee is bent backward, often as a result of landing wrong after a jump. A hyperextended knee can damage ligaments, cartilage and other stabilizing structures in the knee.
Is genu recurvatum bad?
Genu recurvatum is undesirable because it is unsightly and may be associated with chronic knee pain. However, the cause–effect relationship between genu recurvatum and knee pain has been questioned. Various splints mechanically block knee hyper-extension (see Figure 6.21).
Why is genu recurvatum bad?
If this is repeated often over many years it produces genu recurvatum (a knee hyper-extension deformity). Genu recurvatum is undesirable because it is unsightly and may be associated with chronic knee pain.
Is Genu Recurvatum bad?
What causes a knee to hyperextend?
A hyperextended knee is a type of injury to the knee caused by the knee bending too far backward. This painful injury is often easy for a doctor to spot and treat. A hyperextended knee often occurs after high-impact events, such as landing hard after a jump or stopping short when running.
How rare is genu recurvatum?
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.
How many degrees of hyperextension does genu recurvatum cause?
As 5-10 degrees of hyperextension is considered as physiological and hyperextension more than that is pathological. In genu recurvatum, the knee bends backward or goes into a hyperextended position, i.e., past 5-10 degrees of normal knee extended position, as you can see in the above diagram.
What does it mean to have genu recurvatum?
Genu recurvatum is also known as “hyperextension of the knee,” “knee hyperextension,” and “back knees.” It is a deformity in which the knee bends backward, i.e., in a hyperextended position. It may be congenital or acquired. In this deformity, excessive extension (hyperextension) occurs in the tibiofemoral joint.
Can a genu recurvatum cause knee pain?
This deformity or condition is more common in women than in men and people with familial or genetic ligamentous laxity. The hyperextension which has occurred may be mild, moderate, or severe. The development of this genu recurvatum may cause knee pain and even lead to knee osteoarthritis.
Can a ACL tear be caused by genu recurvatum?
But in genu recurvatum, the tibia travels too far forward on your femur, the knee goes in a hyperextended position, so there is an increased risk of getting an ACL tear. Quadriceps contracture is of two types congenital and post-injection contracture in infants.
