Final answer:
Genu recurvatum, an excessive hyperextension of the knee, has several causes including joint laxity, muscle weakness or imbalance, prior knee injury, abnormal bone structure or growth, and neuromuscular disorders.
Step-by-step explanation:
Genu Recurvatum: Major Causes
Genu Recurvatum is a deformity in the knee joint where the knee excessively hyperextends. This condition can be caused by various factors, and it is important to understand the major causes to effectively address and treat the condition.
Your Answer
There are several key causes of genu recurvatum, which include:
Joint laxity or hypermobility: This can be due to genetic predisposition or disorders such as Ehlers-Danlos syndrome.
Muscle weakness or imbalance: Specifically, weakness in the muscles that support and stabilize the knee like the quadriceps and hamstrings.
Prior knee injury: Injuries such as anterior cruciate ligament (ACL) tears can lead to instability and subsequent genu recurvatum.
Abnormal bone structure or growth: Conditions such as osteochondroma can cause abnormal growths on the bones, leading to hyperextension of the knee.
Neuromuscular disorders: Diseases such as cerebral palsy or polio can affect the control of muscles, potentially leading to genu recurvatum.
Understanding and addressing these underlying causes is essential for effective management and treatment of genu recurvatum.
