Q68.2: Congenital deformity of knee

Congenital deformity of the knee is a birth defect where the structure of a baby's knee is not formed correctly. This condition can be apparent at birth or diagnosed as a child grows and develops. The deformity could be related to the bones, muscles, or ligaments of the knee, leading to a variation in the knee's appearance and potentially affecting the knee's regular functioning. Common signs might include an unusual bend or shape of the knee, difficulty in moving the knee, or discomfort in walking or crawling. The severity and kind of deformity can vary significantly from person to person. Deformities might be caused by factors during pregnancy such as certain medications, infections, or nutritional deficiencies, but in many cases, the exact cause is unknown. This condition does not progress on its own, but may affect mobility and overall quality of life. Diagnosis is usually based on physical examination and imaging studies such as X-ray or MRI scans.
