Hi - i agree with the above...I am thinking the L/S.

I have had some patients who had definite knee swelling but we couldn't find anything wrong with the knee...found stuff wrong in the back though...Anyway, treated the back and the dysfunctions we found and within a few days the swelling subsided The superomedial knee pain can be a Saphenous nerve irritation.

Otherwise just make sure all things in the back, pelvis, hip, knees and ankles are all ok.

Cheers!
