Knee replacement surgery can bring much-needed relief to people living with knee pain. If you’re thinking about surgery, you may be wondering how long the results will last.
The good news is that most people enjoy many years of improved movement and less pain after knee replacement. Today’s knee implants are built to last longer than ever before.
What can I expect after surgery?
Knee replacement surgery is designed to restore movement and help reduce joint pain caused by arthritis, injury or other conditions. During the procedure, a surgeon removes damaged bone and cartilage from your knee and replaces it with parts made from metal and plastic.
After recovery, most people find it easier to walk, exercise and enjoy daily activities again. But how long your new knee lasts may depend on a few different factors.
What is the average lifespan of a knee replacement?
Most total knee replacements last between 15 and 20 years. Some new implants may last up to 30 years or longer with good care. Recent studies have found that today’s replacements have addressed many of the issues that led to early revision knee surgeries.
If you are younger or more active, your replacement knee joint may wear out faster over time. But that doesn’t mean you should wait too long to have surgery. Living with pain and limited movement can affect your overall health and quality of life.
Can a knee replacement wear out?
Yes. Over time, the parts in your new knee can loosen or wear down, especially with frequent use or if under extra stress. When this happens, you may need another surgery, called a revision, to replace the worn parts.
Signs that your knee replacement may need attention include:
- Pain that comes back or gets worse
- Swelling or stiffness that limits movement
- Clicking or grinding in the joint
Let your doctor know if you notice any of these changes.
What affects how long it lasts?
Several things can affect how long your knee replacement will last, including:
- Your age and activity level
High-impact activities like running or jumping may wear the new joint down faster. If you want your knee implant to last longer, it’s best to try and stick with low-impact exercises. - Your weight
Carrying extra weight puts more stress on your knee joint, which can speed up wear and tear. - Surgical technique
An experienced orthopedic surgeon can help place the new joint correctly, which improves long-term results. - Follow-up care
Regular check-ups with your doctor help catch problems early.

You can help your knee replacement last longer by:
- Staying at a healthy weight
- Following your physical therapy plan after surgery
- Choosing low-impact exercises like walking, biking or swimming
- Going to regular check-ups with your orthopedic doctor
The answer
Most people enjoy 15 to 20 years of better movement and less pain after knee replacement surgery. In many cases, it lasts even longer. Taking good care of your joint and working closely with your care team can help you get the best results.
