M21.1: Varus deformity, not elsewhere classified

Varus deformity, not elsewhere classified, refers to a medical condition where certain joints, often in the legs, become misaligned and deviate inward, causing the affected area to look bowed or "knock-kneed". This condition can result from a myriad of factors like abnormal bone development, certain injuries, or diseases that affect bone integrity. The common symptom associated with the varus deformity is the visual abnormality, where the affected joints deviate inward when compared to a normal, straight alignment. Moreover, people suffering from this condition may experience discomfort or pain while moving the afflicted limb. Over time, if the condition progresses untreated, it can potentially lead to difficulty in the normal range of motion, excessive pressure on the inner parts of the joints, and even potential arthritis. Varus deformity primarily affects the musculoskeletal system of the body.
