Purchased for my father 2 days out of TKR. Now at 4 weeks out and progressing extremely well he states that the book is execellent and right on with what he has been experiencing. Wishes he would have read it prior to surgery to better prepare himself both mentally and physically. He has specifically repeated the physical preparation as the muscle recovery and the pain expectations he had are the biggest issues.Per his recommendation this is an excellent book to properly prepare yourself.
