Hi all. I just wanted to relate some good results. In May 2014 I had my left distal femur & knee joint removed and replaced with a metal implant. I've been working on my re-hab and muscle mass ever since. I now manage to walk 10 or more pain free kilometers per day, and have regained all my muscle mass - that I progressively lost over my 27 year fight with PVNS. I couldn't be happier now, given that at one point, Orthopaedic Surgeons were advising an above knee amputation. This is a real alternative that has given me back 95% of my former life freedoms.
I've uploaded an image showing my left & right knee, and how well the left one has now recovered.
Regards to all in knee pain world!
