Hip Replacement Age Guidelines: When Is It Appropriate?

There is no absolute age limit for total hip arthroplasty (THA). The decision balances symptom severity, functional impairment, joint damage, and overall health—not chronological age alone.

Typical Age Distribution

• Most common: 50–80 years old
• Average age: ~65 years (US national data)
• Increasing trend: More patients <50 and >85 as implant durability and anesthesia safety improve.

Younger Patients (<50)

• Indications: Congenital dysplasia, post-traumatic arthritis, avascular necrosis, inflammatory arthritis.
• Concerns: Higher activity → higher wear/revision risk; implant longevity (15–25+ years modern bearings).
• Solutions: Ceramic-on-ceramic, ceramic-on-highly-crosslinked-polyethylene, large heads; activity modification counseling.

Older Patients (>85)

• Indications: Fracture (often hemiarthroplasty), severe osteoarthritis with functional dependence.
• Assessment: Frailty index, cognition, cardiopulmonary reserve, social support, goals of care.
• Outcomes: Excellent pain relief and mobility restoration in selected non-frail elders.

Decision Framework

1. Failed non-operative management (PT, NSAIDs, injections, assistive devices).
2. Radiographic evidence of end-stage arthritis (joint space loss, osteophytes, subchondral sclerosis).
3. Symptoms disproportionate to imaging? Consider referred pain (spine, SI joint).
4. Shared decision-making: patient goals, life expectancy, risk tolerance, support system.

Age is a factor, not a barrier. A healthy 75-year-old may be a better candidate than a frail 55-year-old.
