Hip osteoarthritis is a degenerative condition characterized by the progressive wear of the hip joint cartilage. It may be primary (with no apparent cause) or secondary to trauma, congenital dysplasia, arthritis, or metabolic disorders such as diabetes and gout.

The main symptoms include hip pain (often radiating to the groin or knee), joint stiffness, and reduced mobility, particularly during daily activities such as walking or climbing stairs.

Diagnosis is based on medical history, physical examination, and confirmed by X-rays, showing joint space narrowing, osteophytes, and joint deformities. In early stages, conservative treatments are used: medications, physical therapy, and injections. In advanced cases, the most effective solution is hip joint replacement surgery.

Without treatment, hip osteoarthritis can lead to functional disability, chronic pain, and severe stiffness.
