What does a genu recurvatum mean?
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 congenital genu recurvatum?
To the Editor: Congenital genu recurvatum is a rare entity in the newborn characterized by anterior hyperextension of the knee joint, prominence of femoral condyles in popliteal fossa, and increased transverse skin folds over the anterior surface of the knee.
What is the cause of genu recurvatum?
Causes of genu recurvatum included physeal arrest; soft tissue laxity; and complications related to fractures, such as prolonged immobilization and malalignment.
Can you be born with genu recurvatum?
Abstract. 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.
Is genu recurvatum serious?
Genu recurvatum is a deformity in the knee joint, so that the knee bends backwards. In this deformity, excessive extension occurs in the tibiofemoral joint. Genu recurvatum is also called knee hyperextension and back knee….

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.
What causes Banana Legs?
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 does genu recurvatum affect gait?
Genu recurvatum increases the stance phase duration and promotes gait asymmetry (Woolley, 2001; Bleyenheuft et al., 2010). From a practical point of view, retraining the gait pattern in patients with genu recurvatum is relatively complex because of diverse etiologies (Bleyenheuft et al., 2010).
Is genu recurvatum common?
Incidence. This condition is considered to be rare, with about 1 in 100,000 births being affected by the congenital form of genu recurvatum, although it’s a common feature in some disorders, such as in joint hypermobility, which affects 1 in 30 people.
What causes genu valgum?
Mistreated (or untreated) traumatic injuries cause physeal damage or overgrowth (for example), resulting in progressive and disabling clinical deformity. Likewise, untreated congenital anomalies, skeletal dysplasias, genetic disorders, metabolic conditions, and rheumatologic diseases may cause genu valgum.
What would you see on a patient with genu valgum?
What Is Knock Knees? Genu valgum (knock-knees) is a common lower leg abnormality that is usually seen in the toddler, preschool and early school age child. In genu valgum, the lower extremities turn inward, causing the appearance of the knees to be touching while the ankles remain apart.
What is genu valgum?
A person with knock knees (genu valgum) has a large gap between their feet when they’re standing with their knees together.
What is genu recurvatum (genu genu)?
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.
What causes genu recurvatum?
Causes of Genu Recurvatum. The injuries that resulted in genu recurvatum are usually caused by an unexpected impact to the extended knee following an injury to some structures of the knee or just the posterior aspect of the knee structures.
Can genu recurvatum cause knee pain?
The development of this genu recurvatum may cause knee pain and even lead to knee osteoarthritis. The normal active (by own) range of motion for knee extension is 0 degrees (fully straight), and passive knee extension up to 5 -10 degrees is considered normal.
What are the symptoms of genu recurvatum?
A person with genu recurvatum may have difficulty in performing activities that requires endurance. Other symptoms may include: The injuries that resulted in genu recurvatum are usually caused by an unexpected impact to the extended knee following an injury to some structures of the knee or just the posterior aspect of the knee structures.
