Artificial joints are designed to last for many years. In general, most modern hip and knee replacements last 15 to 25 years, and many continue working well even longer. In fact, studies show that about 90% of modern joint replacements still function well after 15 to 20 years.
How long a joint replacement lasts depends on several factors, including your activity level, weight, overall health, implant type, and how well you care for your new joint after surgery.
At Iowa Specialty Orthopedics, our orthopedic experts help patients understand what to expect before and after joint replacement surgery so they can protect their long-term mobility and quality of life.

What Affects How Long a Joint Replacement Lasts?
Every patient is different, and artificial joint lifespan can vary from person to person.
Several important factors can affect how long an artificial joint lasts, including:
- Activity level
- Body weight
- Implant materials
- Surgical technique
- Bone health
- Overall medical health
- Recovery and physical therapy
- Infection or injury risks
Modern implants are stronger and more durable than ever before, but daily wear and tear still affects artificial joints over time.
Does Activity Level Matter?
Yes. High-impact activities place more stress on artificial joints and can cause implants to wear down faster.
Activities that may increase wear include:
- Running
- Jumping
- Heavy lifting
- Contact sports
Staying active is important, but protecting your artificial joint helps extend its lifespan. Low-impact exercises are usually safer and better for long-term joint health.
Does Weight Affect Artificial Joint Lifespan?
Yes. Excess body weight increases pressure on hip and knee replacements, which can speed up wear and loosening over time.
Even small improvements in weight and fitness can make a difference in joint health.
Are Modern Joint Replacements Better Than Older Ones?
In many cases, yes. Modern joint replacement materials and surgical techniques have improved significantly over the years.
Better surgical precision and earlier physical therapy also help improve long-term outcomes for many patients.
How Long Do Hip Replacements Last?
Hip replacements are one of the most successful procedures in orthopedic medicine.
Research shows:
- About 90% of hip replacements last at least 15 years
- Around 70% last 20 years
- Many continue functioning beyond 25 years
Modern hip replacement surgery can provide significant pain relief, improved movement, and better quality of life for many patients.
How Long Do Knee Replacements Last?
Knee replacements also have excellent long-term success rates.
Studies show:
- About 93% of knee replacements last 15 years
- Around 90% last 20 years
- More than 80% may still function after 25 years
Many patients return to walking, travel, hobbies, and daily activities with much less pain after knee replacement surgery.
What Can Cause an Artificial Joint to Fail Early?
Although most joint replacements last many years, some may fail sooner because of complications or excessive wear.
Common reasons for early joint failure include:
- Implant loosening
- Infection
- Joint instability
- Bone fractures near the implant
- Falls or injuries
- Excessive wear on plastic components
Patients should contact an orthopedic specialist if they notice persistent pain, swelling, stiffness, instability, or changes in joint function.
Can Artificial Joints Be Replaced Again?
Yes. If an implant wears out or fails, revision surgery may help repair or replace the artificial joint.
Revision surgery is more complex than the original joint replacement, but it can help restore mobility, reduce pain, and improve quality of life for the right patients.
Many patients successfully undergo hip revision or knee revision surgery years after their first joint replacement.
How Can You Make an Artificial Joint Last Longer?
There are several ways to help protect your artificial joint and extend its lifespan.
Helpful habits include:
- Stay active with low-impact exercise
- Maintain a healthy weight
- Attend regular orthopedic check-ups
- Follow physical therapy recommendations
- Avoid falls and joint injuries
- Prevent infections when possible
Routine follow-up visits and imaging can help detect small problems early before they become more serious.
