Osteoarthritis is the most common cause, however, other causes include post-traumatic arthritis, rheumatoid arthritis, rickets, and renal osteodystrophy. Regardless of etiology, the valgus malalignment can be corrected with careful analysis of the deformity and a systematic surgical approach.

What muscles causes valgus?

A common improper movement pattern observed during a squat is knee valgus (knees caving inward). This is typically the result of strong hip adductor muscles (located on the inner thigh) overpowering the weak hip abductors (gluteus minimus and gluteus medius).

What is a valgus deformity of the foot?

Hallux valgus deformity is a very common pathological condition which commonly produces painful disability.
