Hello, is it from, trying to think of the name, my friend had both done, might of been arterial sclerosis? he had some ups and downs but he is getting about real well now with a cane some days and some days he gets about without a cane. he had a rough go but is doing good now the rehab did take time and he is a few years younger so he had it when he was 39 or 40? he too had to drop some weight also to get it done, I know he got something from doc at that time i a
have no idea what, but it worked,

I hope some more folks can help shed some light on this, I hope if you choose replacement it works out well, I've also talked to others, older than myself, over the years that had it and most were hesitant, but glad after wards
