What is Coxarthrosis (Hip Osteoarthritis)?

Pathology of Hip Osteoarthritis (Coxarthrosis)

Coxarthrosis is degenerative joint disease of the hip involving gradual breakdown of articular cartilage covering the femoral head and acetabulum. As cartilage thins, subchondral bone sclerosis, joint space narrowing, and peripheral osteophytes develop.

Primary Clinical Manifestations

• Deep groin pain radiating down the anterior thigh to the knee
• Stiffness upon initiating walking after rest and morning limitation
• Difficulty with hip rotation required to put on shoes and socks
• Progressive limp (antalgic gait) and reduction in walking endurance

Management and Total Hip Arthroplasty

Early stages benefit from weight management, low-impact exercise, and intra-articular therapies. When end-stage cartilage loss occurs, total hip replacement delivers long-term pain relief and restores functional mobility.

Frequently Asked Questions

Why does hip arthritis pain often present in the knee?

Referred pain from the hip commonly travels along the obturator and femoral nerve pathways, leading patients to perceive primary discomfort around the knee.

What is the lifespan of modern hip implants?

With advanced ceramic-on-crosslinked-polyethylene bearings, total hip prostheses routinely function successfully for 20 to 25+ years.
