I tell my patients getting a new joint is a lot like buying a brand new car. The better you treat it, the longer it’ll last. The worst results of joint replacement surgery is in patients who abuse their joints. The worst results are in young, active patients. If you treat the joint well, it should last a long time. Prior studies have shown that 95% of joints done twenty years ago are still in at twenty years. Today we are doing joints in younger and younger patients, and we hope, with newer materials, that they will last even longer.
