My husband has total knee replacements in both knees.
They help you get up 3 or 4 hours after the recovery room. Sometimes it is the next day.They have physical therapy come down to help you and just do a little bearing on that leg for a few minutes. Then you sit in a chair or get back in bed.
The therapist will bring in a CPM machine, put it on your bed, strap your leg in it and it slowly raises your leg up and down to help gain strength and keep blood clots away. The next day or two the therapist will help you walk with a walker.
Them you go home, the machine is delivered to you and you will need someone to help you, and cook and those things for you, and when the doctor says, you need someone to help you to get in and out of the shower. You put your leg in the machine, pull the straps and velcro them. You have to use the machine for two hours three times a day. You can get around to the bathroom and back on your walker. Your doctor will tell you the rest of his instructions.
You do not learn to walk again! You only need help from a therapist for one to two days and when you get home you walk in with your walker and even up steps into your house. You still have your balance and all. The only difference is you will find out how much or little weight to put on the leg. YOU CAN WALK ON YOUR OWN THAT DAY AND AFTER!!!!!!!
Discharge Your hospital stay may last from 3 to 7 days, depending on how well you heal after surgery. Before you go home, you will need to meet several goals: Get in and out of bed by yourself Bend your knee approximately 90° or show good progress in bending your knee. Extend (straighten) your knee fully. Walk with crutches or a walker on a level surface and to climb up and down 2 or 3 stairs. Do the prescribed home exercises.
