Like I said upthread, my experience with the medical profession on this subject was less than satisfactory. Around here, they know how to treat football players and maybe runners. OTOH, all the videos I use to learn to tape my knee came from PT's, so they are out there. But I'm pretty sure the number of orthos or PTs that know how seat height affects your knees is vanishingly small, and most wouldn't think of that at all.
