Please advise anyone who has had joint replacement surgery.

My father originally had knee problems.

It's not a disease with any particular reason; she just works too much and uses her knees a lot, so her cartilage has worn out completely, and now the bones are almost touching each other.

So, I also received the procedure once.

The improvement was temporary, and since a month ago, she has been in so much pain that she can hardly leave the house, and even going to the kitchen at home is difficult for her.

How many years is the lifespan of a joint replacement, and is it possible to have a second surgery?
