The physiotherapist will get you up on the first or second day after surgery, and will teach you some home exercises after total knee replacement and to put on the right amount of weight on your operated leg.

During waking hours you should “pedal” your feet up and down every five minutes or so, the entire time you are in the hospital, to help prevent blood clots from forming.

The pedaling exercise, the pumps and the stockings all help to prevent blood clots from forming in your legs.

After the surgery (usually on the second day) the leg is placed in a CPM (Continuous Passive Motion) machine (if there was preoperative stiffness) which will gradually exercise your knee. This machine will help you regain your knee movement. The amount of movement that the machine goes through will be gradually increased over the course of your hospitialization. You will be taught how to increase the amount of bending by adjusting the controls on the CPM.

By the time you leave the hospital we like you to have at least 90 degrees of knee motion and good control of muscles about your knee.

You can go home when you are able to get in and out of bed by yourself, and go to the bathroom by yourself. Some patients reach this goal within five days, others take as long as ten days.

You will need crutches or a walker to help with walking for about six weeks after surgery.

A toilet seat extension will be needed so that you do not sit too low on the toilet. If you live in a two-story house, it is recommended that you move a bed downstairs and convalesce there, rather than risk using stairs. You will also need a thermometer and a shower stool.
