My DD has now had injured both knees, MCL tear last season on left and sprained right this season. Rehabbed and recovered from both, but looking for future prevention in addition to the docs recommended stretching routine before games. I was looking at knee compression sleeves she could wear under pants during games and wanted to see if anyone else was using these at catcher, and what kind. It looks like they would have the tendency to slide down and bunch up around knee.
