Is any elbow replacement good.?

Yes it is good: If it done for the right diagnosis and in the right hands.

Yes and no: You never want to get a joint replacement if you don't have to, because it's never as good as the real thing. However, if your elbow is painful and arthritic, total elbow arthroplasty (tea) is a good option. Tea is also used when the joint is destroyed due to trauma and cannot be reconstructed.
