After a knee replacement, the scar tissue below the knee starts to heal abnormally and may adhere to the skin and kneecap, thus preventing your knee from moving properly.
You should begin performing scar massage only after your staples have been removed and your steri-strips have fallen off. Make sure that the incision is well healed.
Place thumb or two fingers at the top of the scar, directly over the incision. Press deeply to massage the underlying tissue and rub sideways across the scar (not up and down). Continue to massage (side to side) the entire length of the scar slowly, spending a few seconds at each area.
You can perform scar massage as often as you want. The more the better! If you notice that an area of the scar starts to drain fluid, stop doing the scar massage until the incision heals completely.
DO NOT USE LOTION BEFORE PERFORMING THE SCAR MASSAGE. You want there to be friction between your thumb and the scar so that you can break up the scar tissue.
