That`s GREAT!
I had a neighbor a block away that could barely walk with a walker 4 weeks post Op.
I guy I used to work with had both knees done. His left leg was turned out great, but his right knee bothered him for a year. The DR. that did the operation just told him keep up with the exercise and pain meds.
He went to a different Ortho surgeon and after X rays he was told he had two Left knees installed!
He sued the Dr. that did the surgery, and must have won big, because he retired early!
