Who Is a Good Candidate for Hip Replacement?

Hip replacement can significantly improve pain and mobility when a damaged hip joint is no longer functioning well. But having hip arthritis or another hip condition does not automatically mean that you are a candidate for surgery.

A good candidate is generally someone whose hip problem is causing significant pain or functional limitation, whose symptoms have not improved enough with appropriate non-surgical treatment, and whose overall health allows the potential benefits of surgery to outweigh its risks.

If you are considering hip replacement surgery, understanding how candidacy is assessed can help you have a more informed discussion with your orthopaedic team.

What makes someone a good candidate for hip replacement?

There is no single checklist that automatically determines whether someone should undergo hip replacement. Doctors usually consider several factors together. A person may be considered a suitable candidate when:

• Hip pain is persistent or significantly limiting.
• Hip stiffness or reduced movement interferes with daily activities.
• Walking, climbing stairs, dressing or other routine activities have become difficult.
• The hip has significant structural damage.
• Appropriate non-surgical treatments have not provided sufficient relief.
• The symptoms are substantially affecting quality of life.
• The person is medically fit enough to undergo the procedure.
• The expected improvement in pain and function is considered to outweigh the potential risks of surgery.

1. Your hip problem is causing significant symptoms

One of the most important considerations is how much the hip condition is affecting you. Hip replacement may be considered when pain or stiffness makes everyday activities increasingly difficult. 

You may find it harder to walk, climb stairs, get into a car, rise from a chair, put on socks and shoes or sleep comfortably. The impact on daily life matters because the primary goals of replacement are to relieve pain and improve function.

2. Non-surgical treatment is no longer enough

Hip replacement is generally not the first treatment for hip osteoarthritis. Depending on the underlying condition, doctors may first recommend approaches such as therapeutic exercise, physiotherapy, weight management when appropriate, pain-relieving medicines or other measures to improve symptoms and function.

If these treatments have been tried appropriately but your pain and functional limitations remain substantial, replacement may become a reasonable option to discuss.

3. There is evidence of significant joint damage

Imaging can help determine the condition of the hip joint. X-rays may show changes such as narrowing of the joint space, loss of cartilage and other structural changes associated with advanced arthritis.

However, an abnormal X-ray alone does not make someone a candidate for hip replacement. The imaging findings need to correspond with the person's symptoms and functional limitations. Someone with substantial changes on an X-ray but little pain may not need surgery at that point.

4. Your symptoms are affecting your quality of life

Hip disease can gradually restrict more than physical movement. Some people stop exercising, reduce social activities, avoid travelling or become increasingly dependent on others because of pain and mobility problems.

When a hip condition begins to interfere substantially with independence and quality of life, this is an important factor in considering joint replacement.

Does age determine whether you are a good candidate?

No. There is no universal age requirement for hip replacement. Hip replacement can be considered in younger adults when severe joint disease causes significant pain and disability. Older adults may also be suitable candidates when they are experiencing substantial symptoms and are medically fit for surgery.

Age can influence surgical risk, recovery and the likelihood of needing further treatment later in life, but it is considered alongside overall health, mobility, joint condition and expected benefit rather than used as the only deciding factor.

Can someone with other medical conditions still have a hip replacement?

Yes, in many cases. Having another medical condition does not automatically rule out hip replacement. Conditions such as diabetes, high blood pressure, heart disease or lung disease may require careful assessment and optimization before surgery.

The surgical and anaesthesia teams consider how well these conditions are controlled and whether they increase the risks associated with the procedure.

Sometimes surgery may be delayed while a medical condition is treated or better controlled. This does not necessarily mean that hip replacement will never be possible.

What about obesity?

Body weight can be relevant when assessing suitability for hip replacement because higher body weight may increase the risk of certain surgical and postoperative complications.

However, weight is only one part of the assessment. The decision should take into account the person's overall health, mobility, severity of symptoms and individual surgical risk. When appropriate, improving fitness and managing weight before surgery may help reduce risks and support recovery.

What if you have had previous hip surgery?

Previous surgery does not automatically exclude someone from hip replacement. However, earlier procedures can affect the anatomy of the hip and may make the operation more complex. The surgeon may therefore need to review previous surgical records and imaging carefully before determining the most appropriate approach.

Can a younger person be a candidate for hip replacement?

Yes. Younger age alone is not a reason to exclude someone who has severe hip disease and substantial symptoms. Conditions such as advanced osteoarthritis, inflammatory arthritis, previous hip injury or other disorders can cause significant joint damage in younger adults.

However, because younger patients have more years of expected use ahead of them, the possibility of implant wear and future revision surgery may be part of the discussion.

What conditions commonly lead to hip replacement?

Hip replacement is most commonly associated with advanced osteoarthritis, but several conditions can damage the hip joint. Depending on the circumstances, replacement may be considered for:

• Advanced osteoarthritis.
• Inflammatory arthritis.
• Hip damage following certain injuries.
• Avascular necrosis of the femoral head.
• Some developmental or structural hip disorders.
• Other conditions that cause severe joint damage and persistent symptoms.

The underlying diagnosis helps determine whether replacement is appropriate and which type of procedure may be required.

The Bottom Line

A good candidate for hip replacement is not defined by age or an X-ray alone. The strongest consideration is usually the combination of significant symptoms, reduced function, structural joint damage and inadequate relief from appropriate non-surgical treatment.

Your overall health also matters. Medical conditions, weight, smoking, previous surgery and other factors can influence the risks of the operation and may sometimes need to be addressed before surgery.

Ultimately, candidacy is individualized. The right time for hip replacement is when the expected improvement in pain, mobility and quality of life is considered to outweigh the potential risks, based on your specific health and circumstances.
