Discussion

Background

Osteoarthritis is a group of conditions encompassing a primary abnormality of joints lined by hyaline cartilage and also reflecting a common final pathway of degenerative changes and attempted repair. It represents the most common arthropathy, its prevalence increasing with age.

Clinical Findings

Patients are typically middle-aged or older. There may be a history of trauma to the joint, especially in those patients presenting at an early age. The increasing prevalence of obesity is associated with an increasing incidence of osteoarthritis, particularly in the lower extremities. A history of other predisposing conditions may be elicited, for example, prior avascular necrosis of the femoral head, acromegaly, Wilson’s disease, intra-articular hemorrhage, and chronic neurologic conditions.

Erosive osteoarthritis is characterized by an abrupt onset of painful joints, with morning stiffness and occasional throbbing paresthesias of the fingertips.

Complications

·Joint pain

·Loss of joint function

·Bone necrosis

·Joint ankylosis
