I have two friends that have had both knees done at the same time and
are both in their mid to late 60's...an intense option to be sure with much
rehab required...both are happy with results and one maintains their bike
and boarding joys as one is able to hike like they used to...:)
and another...
Joey, who is now 71 and Bikes, Surfs, Skis and Carves all with dakine Style
he had before...a mentor for us all :)
My Sister who is now 69 had this done 12 years ago and went from being a total invalid to
once again walkin round the block :)
From what I have seen...I would not hesitate myself if and when required.
