'Heel slides' are a simple early exercise to maintain some active range of movement. They can be done in bed even while the knee is still painful, as long as the surgeon allows it and the knee is not in an immobiliser. Pop something slippy under the heel (like the tea tray pictured here) to make the slides easier.
|Lie on your back with one leg bent and the other extended.|
|Concentrating on the heel of the painful knee, slowly slide the heel up towards the other.|
|Rest with both knees bent for a second and then slowly relax back down to the starting position. Alternate legs. Repeat 5 to 10 times.|
