Does anyone have a hinged knee replacement?

Does anyone have a hinged knee replacement? If so I'd like to hear about your experience. How was the surgery and recovery? How does it feel? How is it walk and climb stairs with?

I had my knee replaced 4 years ago and I've dislocated it three times. With the latest dislocation occurring last June. My doctors are telling me that a hinged knee replacement is my best solution and they scare me to death.

Anything you can tell me about will be greatly appreciated!
