Knee replacement surgery is a treatment for severe knee arthritis. Most patients understand that knee replacements can wear out over time, but exactly how long is a knee replacement supposed to last?
Knee replacements eventually wear out. Unfortunately, an artificial knee is not as durable as your own knee. Because the knee replacement implants are made of metal and plastic, over time, these materials begin to wear, just like the rubber on your car tires. While knee replacements are designed to last a long time, they will not last forever.
