Can liposuction of the upper thigh and knee area help with primary Osteoarthritis of the knees?

Thanks for your questions. Congratulations on the weight loss so far.  Liposuction is for cosmetic contouring via fat cell removal, but is not for weight loss and therefore would not help your lower extremity symptoms.  Initially during the healing process, liposuction would actually make your swelling worse.  If you continue to have lower extremity edema, you should be evaluated for possible other causes (ie, venous insufficiency).  Best of luck with your continued work towards your goals.

Sorry to hear that your osteoarthritis is being complicated by diabetes, weight gain, and neuropathy.    Liposuction actually removes very little weight and would not improve your symptoms.   Additionally, liposuction may make the edema of your legs worse.  You may want to see if your primary care physician can do a work up for lymphemema or venous reflux to help explain the leg swelling.
