Knee injection day

John, my 74 year old brother had his knees replaced one at a time because he didn’t want to be a complete invalid during his healing time. His recovery on the second knee went quicker because he knew the pain threshold of the rehab effort from the first one. The first one was when he was 73 and the second one was done 9 months later. He used crutches to get around until he could walk on the leg that had the operation.
