Arthrogryposis, suspect congenital absence of ACL


US – Hyperextension of the knees with anterior translation of the tibias relative to the femora.


Arthrogryposis multiplex congenita is merely a descriptive term referring to multiple contractures noted at birth related to decreased intrauterine fetal movement. Normal joint development is dependent upon movement. The earlier in gestation that movement is limited, the more severe the contractures.

Males and females are equally affected. Myopathy (muscular dystrophy, mitochondrial disease, abnormal muscle), nerve dysfunction (neurologic syndromes, anterior horn spinal cord dysfunction, myelomeningocele,cnetral or peripheral nerve dysfunction), connective tissue disease, mechanical constriction (oligohydramnios, uterine fibroids, amniotic bands, trauma and multiple gestations), maternal factors (diabetes mellitus, hyperthermia, infection, drug use) contribute to development of arthrogryposis.

Clubfeet, hip dysplasia, and hyperextensibility are commonly associated with arthrogryposis. Dimples are often seen over the affected joints. Muscle mass is diminished. Scoliosis often develops. Arthrogryposis responds well if therapy is initiated before 12 months of age.
