A week ago, Betty came home from the hospital after a total knee replacement. She's been walking around the house on her walker and has been working with nurses, ocupational therapists and physical therapists here at home. Part of her therapy is to use a CPM (Continuous Passive Motion) machine. We have affectionately named it The Iron Maiden as each time she gets comfortable, we get to increase the setting. She's using the cpm two hours at a time and is looking forward to the time that she no longer will need to use it.
Notice the ice pack on her knee. It's an inexpensive icepack you can buy at any grocery store. We've never gotten so much mileage out of one bag of frozen peas.
