How Long Does a Knee Replacement Last?

Knee pain can wear you down, especially when it keeps you from doing the things you love. For many people, knee replacement surgery becomes a real option when pain relief and mobility just aren’t improving with conservative treatments. One of the most common questions we hear at Specialty Orthopaedics is, “How long does a knee replacement last?”

Our board-certified orthopaedic surgeons in Harrison, New York, have been treating complex joint conditions for years. Knee care is led by Dr. Steven Zelicof, a joint reconstruction and arthritis specialist and expert in primary and revision knee replacement surgery. 

We understand the decision to have surgery isn’t always easy. Let’s take a closer look at what you can expect from a knee replacement over time.

The Typical Lifespan of Modern Knee Replacements

Thanks to advances in materials and surgical techniques, most knee replacements last between 15 and 20 years, and often longer. Many people find their artificial knee continues to function well beyond that window, especially if they’re in good health and take care of their joint after surgery.

The durability of your knee replacement depends on several factors, including the type of implant used, how well it’s placed, and how your body responds to it over time. Some patients who had knee replacements 20 or 30 years ago still have their original implants today.

What Makes a Knee Replacement Last Longer?

You personally play a big role in how long your knee replacement lasts. Things like your activity level, weight, general health, and commitment to physical therapy can all influence how your joint holds up. High-impact activities like running may shorten the lifespan, but we usually encourage walking, biking, and swimming once you’ve recovered.

Surgical technique also matters. Dr. Zelicof offers advanced options like Mako robotic-assisted joint replacement, which helps improve precision and alignment. Better positioning can mean less wear and better long-term results.
