Oops. The aforementioned "vice clamp" would be something that helps one get a firm grip on ones addictions, perhaps. A rather secure coffee mug holder, for example. I think I really meant vise.
On the related subject of the bruise(s) my physical therapist says they show up downstream from the trauma site...that I could even end up with bruises on my foot from having knee surgery. Sure enough, there are some. Physical therapy felt pretty good. We took off the brace and I tried to let gravity bend my leg to 90 degrees dangling off the edge of a table. Felt sort of good to bend, and sort of not. All my pre-surgery biking definitely paid off. The PT and the assistants commented on how good my quadricep strength is considering we're four days after surgery. I can unlock the brace for sitting around so that I can get more bending practice, but it has to be locked at zero (straight) to walk on it.
