Oh Gosh * Phobes* that sounds awful. I hope you get it sorted out soon.
I have had both knees done 2 years ago (five months between each one). Luckily , I am thrilled with the result. I have also lost just over 3 stone in weight, with some more to go, which of course helps. I feel and look 10 years younger. The best bit is being without the pain.
