On my current knee replacement the doctor used a different type of bandage on the wound. This piece was long and seemed to be made of a heavy duty plastic or leather. The part that actually touched the wound, was heavily padded. And the outside had some type of heavy-duty adhesive the would easily re-adhere when you pulled it off and put it back on. I have been trying to find one of these online but have had no luck. Has anyone heard of this product and if so, do you know who makes it?
