secondary osteoarthritis

Secondary osteoarthritis occurs when joint changes result from a prior abnormality in the joint's structure or alignment. This is distinct from primary osteoarthritis, where no specific cause can be identified.1

Common causes of secondary osteoarthritis include congenital hip dysplasia, where the hip joint doesn't fit together properly, often due to how infants are positioned. Other contributing factors can be injuries that lead to chronic irritation or permanent joint deformity, repetitive microtrauma from activities like using pneumatic drills or certain sports, and even hormonal imbalances.12

While osteoarthritis itself is a progressive deterioration of joint cartilage and surrounding tissues, secondary osteoarthritis specifically arises as a consequence of these pre-existing conditions. Treatment often involves pain management, physical therapy, and sometimes surgery, depending on the severity and location of the affected joint.12
