I did it in the trial, unfortunately I was given placebo or it didn't work for me
An hour each way travel and then at the clinic for up to 3 or 4 hours was hard work
Ended up having both knees replaced. I did contact PR via email 3 or 4 times asking for the PPS. He never even bothered to reply.
Was a bloody awful experience all round.
I appreciate that you might get 12 months relief or more, and if DMOAD who knows
I am over 4 months since having both replaced and it has been quite a journey to be honest but I am still better off than I was before the surgery and getting better and better all the time. This should last at least 25 years so glad I went through with it.
