My 83-year-old father recently injured his knee. He came home from rehab on Tuesday. He can ambulate short distances with the walker but will need someone with him to assist. He will also need help with toileting. We will need help with driving his car to his doctor's appointments from time to time. He is very sweet, oriented, and appreciative of any help and assistance. He has a desire to return to his prior state of health before the knee injury.
