What most people call a knee sprain is actually a slight tear. A knee brace can minimize the risk of further injury, but it will not make the pain go away. My guess is whatever they can do to dumb down the physical strain on the knee, they will do, and I would expect him to perform only as many times as necessary prior to the Tony nominations, and then take a break for a week or so. His knee will not get better, however, until he can take some extended time off. He will probably wearing the knee brace for as long as he is in the show. My only medical bona fides come from having sprained a knee many years ago. I remember the initial pain (I thought I had torn my leg in half), the tenderness lasting for weeks, and how the brace gave me the confidence to start moving around more naturally after just a week or so. With a brace, he should be able to function without doing further damage to the knee, but it is going to hurt....a lot. Despite his upbeat social media posts, do not think for a minute that what he is doing is not gutsy as hell. He's in Kerri Strug territory.
