The degree of genu valgum can clinically be estimated by the Q angle, which is the angle formed by a line drawn from the anterior superior iliac spine through the center of the patella and a line drawn from the center of the patella to the center of the tibial tubercle. In women, the Q angle should be less than 22 degrees with the knee in ...
A valgus deformity is a condition in which the bone segment distal to a joint is angled outward, that is, angled laterally, away from the body's midline. [1] The opposite deformation, where the twist or angulation is directed medially, toward the center of the body, is called varus.
Generally, diseases outlined within the ICD-10 codes Q65-Q79 within Chapter XVII: Congenital malformations, deformations and chromosomal abnormalities should be included in this category. Wikimedia Commons has media related to Congenital diseases and disorders of musculoskeletal system .
It is correct for a knock-kneed deformity to be called both a varus deformity at the hip (coxa vara) and a valgus deformity at the knee (genu valgum); although the common terminology is to simply refer to it as a valgus knee. When the terminology refers to a bone rather than a joint, the distal segment of the bone is being described.
Coxa valga is a deformity of the hip where the angle formed between the head and neck of the femur and its shaft is increased, usually above 135 degrees.. The deformity may develop in children with neuromuscular disorders (i.e. cerebral palsy, spinal dysraphism, poliomyelitis), skeletal dysplasias, and juvenile idiopathic arthritis.
It is also used to correct a coxa vara, genu valgum, and genu varum. The operation is done under a general anaesthetic. [1] Osteotomy is one method to relieve pain of arthritis, especially of the hip and knee. It is being replaced by joint replacement in the older patient. [2] Due to the serious nature of this procedure, recovery may be extensive.
[7] People with genu valgum have larger than normal Q-angles causing the weight-bearing line to fall lateral to the centre of the knee causing overstretching of the MCL and stressing the lateral meniscus and cartilages.

Temporary hemiepiphysiodesis is widely used to treat angular or coronal plane deformities around the knee in children i.e. deformities occurring in the medial/lateral plane as genu varum/ genu valgum. Additionally, it has been used to treat sagittal plane deformities i.e. deformities arising the anterior/posterior plane.
