How long does a joint replacement last?

Modern joint replacements are designed to function for many years, but no implant can be guaranteed to last for a specific lifetime. Current patient guidance notes that many hip replacements last at least 15 years, while knee replacements can last 20 years or more. Some implants continue to work well for considerably longer, while others may require revision earlier.

How long a replacement lasts depends on several factors, including the joint involved, implant design, quality of the bone, age, body weight, activity level, previous surgery, and whether complications such as infection occur. Very high-impact activity can place additional stress on some joint replacements, which is why surgeons usually recommend appropriate long-term exercise rather than repeated high-impact loading.

Regular follow-up is useful even when the joint feels good. If an implant wears, loosens, becomes infected, or is damaged after an injury, revision surgery may be needed. Patients should discuss expected implant lifespan and suitable activities with their surgeon because recommendations vary by joint and individual circumstances.

Patients should discuss the answer in the context of their own symptoms and medical history, because the same condition can behave differently in different people. A proper examination helps confirm the diagnosis, identify factors that may change treatment, and set realistic expectations about pain relief, movement, recovery, and return to normal activity.
