Does a knee brace help with knee pain?

Yes, it will help prevent further damage.  You need to wear it and use it for as long as it takes to get better.

Does it also help with arthritis?
user
No.  It does not help with arthritis.  It will help to prevent further damage to your knee from osteoarthritis.  It is not clear to me whether it will help you recover from osteoarthritis.

Can you wear it all day?
