How Long Do Joint Implants Last, and When Do They Need to Be Replaced?

Hip and knee replacements are built to last, but they are not permanent. If you have one now or are thinking about surgery, it helps to know what to expect in the long run. 

Dr. Alexander S. McLawhorn, an experienced orthopedic surgeon in New York City and Stamford, Connecticut, is nationally recognized for his work in robot-assisted hip replacement. He also serves as Director of Research and Innovation at the Hospital for Special Surgery. His work focuses on helping patients get the most out of their joint replacements, not just during recovery, but for years to come.

How Long Do Joint Replacements Typically Last?

Most modern joint implants last 15 to 20 years, though some can function well beyond that. Longevity depends on several factors, including the type of implant used, as well as your activity level, weight, and health. Dr. McLawhorn uses implants made from advanced materials engineered to resist wear, which may support longer-lasting results.

It is worth noting that hip and knee implants may have slightly different durability timelines. In general, hip replacements tend to last a bit longer than knees. If you are younger and more active, there may be a higher chance of needing a revision procedure at some point. 

When Do You Need to Replace a Joint Implant?

Most joint implants don’t need to be replaced unless they start to fail. Some signs that your implant may be wearing out include new or worsening pain, stiffness, instability, or limited range of motion. In some cases, Dr. McLawhorn can spot any issues during routine follow-up imaging before you even have symptoms.

If revision surgery becomes necessary, it involves removing the original implant and replacing it with a new one. Dr. McLawhorn has extensive experience in initial and revision joint replacements using modern technology.
