Hi there!

I would use the 37008 - Strap Above Knee Garment

Webpage: http://www.healingenhancements.com/straptorso-aboveknee37008.aspx

It will cover all of the areas you mentioned and the zipper is located in the center, away from the outer thigh area.  The suspenders ensure that the garment will not roll down either.

If you have any other questions, just let me know.
