@amytro. When cortisone stopped working for me, I got synvisc shots, and they did help a lot. I could have had the knee done six months after my liver transplant but I simply couldn’t face another surgery and recovery so I waited until a year after my transplant. At that point I was definitely more up to doing the exercises to ensure that the TKR was a success.
If you decide to try synvisc, you can have one shot, or a series of three, one a week. I chose the latter.
