If you have osteoarthritis of the kneecap and the cartilage at the back of it has deteriorated, then of course it's beneficial to have it replaced with a patellar button.
Some surgeons (like mine) insert a patellar button routinely when they do a TKR, so they don't have to go back later and do it. Others say that it's unnecessary in most cases, so they don't do it. I don't think there's any right or wrong approach.
Having a patellar button inserted is a much less serious operation than having the original TKR.
