How Long Does a Hip Replacement Last?

Living with persistent hip pain and struggling to move the way you used to? The idea of a hip replacement might feel both hopeful and daunting. If you’re going to undergo a serious surgery and considerable rehab, you want to know that it will deliver long-lasting relief, not just a temporary fix. 

That’s why, for many people, one of the first questions they ask is: How long does a hip replacement last?

This guide walks through the expected lifespan of your hip implant, what influences the outcome, and how to give your new joint the best chance to last longer.

Hip Replacement & Longevity

Hip replacement surgery is a commonly performed procedure in modern medicine, and one of the most reliable ways to relieve chronic hip pain. It replaces the damaged joint with an artificial implant to restore mobility, reduce pain, and improve your quality of life.

The Average Lifespan of a Hip Replacement

Thanks to advances in surgical techniques and implant materials, the average lifespan of a hip replacement is longer than ever before. According to the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR), approximately 95% of joint replacements last at least 20 years. With careful post-op care, most patients can expect long-lasting results, with revision surgery (a replacement of the prosthesis) only needed in a small number of cases.

Understanding Revision Surgery

Sometimes, a hip implant may wear out, loosen, or develop issues requiring revision surgery. This involves removing and replacing part or all of the original implant. Common reasons include infection, instability, dislocation or mechanical wear and tear over time. 

Revision surgeries are relatively uncommon. For most patients, their first hip replacement is also their only one. That said, your age, activity level, and overall health can influence whether a revision might be needed down the line.

Signs a Hip Replacement May Need Revision

Hip implants usually last for decades, but it’s still important to watch for any warning signs that something’s changed. These might include

• Ongoing or worsening hip pain

• A feeling that your hip is unstable or shifting

• Stiffness, reduced range of motion, or difficulty walking or standing

• Signs of infection (redness, swelling, or fever)

• A noticeable change in leg length or joint posture

What Affects How Long a Hip Replacement Lasts?

Every patient is different, and several factors impact how long a hip replacement lasts. Knowing these can help you and your hip replacement surgeon make personalised choices to maximise outcomes.

Your Age and Activity Level

Younger, more active patients tend to put more stress on their implants over time. This doesn’t mean younger people can’t have great results, it just means they might require revision later in life. In contrast, older adults often see longer-lasting results due to lower-impact activity levels.

According to the AOANJRR, the average hip replacement age in Australia is 68, but the number of people requiring hip replacements is steadily increasing in both younger and older age brackets.

Reason for Surgery

Patients receiving hip replacements due to osteoarthritis generally have better long-term outcomes. If you’re undergoing surgery due to a fracture, rheumatoid arthritis (a chronic autoimmune disease affecting joints), or avascular necrosis (bone tissue death due to insufficient blood supply), it can affect how well the implant functions over time.

Implant Type and Surgical Technique

Modern implants, including dual mobility systems and next-generation materials, are designed to improve durability and reduce wear. Factors such as computer-assisted placement and careful surgical technique help reduce complications and speed up recovery. Use of the anterior approach has a higher rate of surgical complications, including nerve injury, fracture, and early loosening that requires major revision.

Health and Lifestyle Factors

Body weight, general health, and commitment to hip replacement management, such as physiotherapy, wound care, and exercise, all play a major role in implant success. Higher BMI and chronic conditions like diabetes may slightly increase the risk of complications or early revision. And while staying active is important, choosing low-impact exercise over high-impact sport can protect your implant long term.

Maximising Implant Longevity

While implant design and surgical skill matter, your actions post-surgery make a difference too. Here’s how to support your new joint:

• Stick to your rehab plan. Regular physiotherapy and home exercises build strength and support your new joint.

• Keep your weight in a healthy range. Less pressure on your hips means less wear on your implant.

• Choose joint-friendly movement and low-impact sports. Walking, swimming, cycling, and gentle strength training are great options.

• Stay connected with your care team. Ongoing check-ups with your surgeon help catch issues early.
