I had mosaicplasty (Cartilage / Bone Transplant - Cadaver to the Talus) a year ago. I can say I am surprised that I am still having hard times, long distance walk (more than 5 blocks) and prolong standing (more than 10 min) and my ankle which I consider an entity these days, will pound out of control. I seen my OS a few weeks ago for my 1 yr follow up and I expected him to have some miracle solution and he told me "it is what it is" and this is the best I can expect and I guess I can live with it but it surely is not what I expected and my friends, hubby etc,. can't understand why I am still in pain and why I judge any activity to if its worth the pain I'll pay.
Now at least I know that this is all I can expect and I guess I can live with it, I just expected to be where I was at prior to the latest injury and I am nowhere near it. It has taken nearly a year for it to even remotely begin to behave, so hang in there. If it doesn't get better call your Doc and if they aren't concerned go elsewhere.
I wish you the best. Hang in there!
