My doctors has suggested a knee replacement, but I think I can go without it for a few years.   Any thoughts?

Whether knee replacement is necessary depends on your medical history, level of knee pain, physical condition and other factors. It is best to discuss the matter with your doctor to get a more accurate idea of the best option for your health needs.
