What Size SBD Sleeves Should I Get?

My knees fall right in between the medium/large size for a “tight fit”. What would be more beneficial, medium or large? I’m not really looking for any “assistance” from them, just something there to give me a bit more stability and long term health for my knees.

I like the tight fit. At first the sleeves were difficult to put on but it’s easy if you fold them before slipping them on or flipping them inside out first. There should be YouTube videos showing how to put them on without difficulty.
