I Have Joint Pain in my Knees Following my Lipo, Full Torso Male, 7 Weeks Ago. Is This Normal?

Swelling goes south with gravity and you will experience some swelling in your legs, knees, ankles, before the fluid is absorbed. At 6 months you should notice this will be resolved.

Joint pain is a bit unsual. Most patients just have soreness fromt he procedure more in the subcutaneous level or at the muscle level.  An exam is probably important to figure out if you had previous joint problems before, etc..  Speak with your surgeon or go in for a visit.
