159lbs, will a BBL help with my knee problems? (Photo)

Dear Honest640966,
based on your photos, you look like a good candidate for a BBL. Liposuction of your abdomen, back and flanks should give you more curves and hourglass shape and fat transfer to buttocks should give you more projection. I would suggest you to consult a board-certified plastic surgeon because only after a thorough examination you will get more information and recommendations.

Hello Honest640966! Please be aware that if you've had knee pain for long-term - it's a sign that something is wrong and needs attention. It could be something serious or not; but you will need a professional (certified and licensed) physical therapist to determine this.

Relocation of your body's fat will not increase knee stability.

If there isn't any pain and it's purely weakness that's your concern; please do research on knee stability exercises and stretches, popular/common weak-knee-associated muscle imbalances, and proper/functional body mechanics. Many people live their entire lives with muscle imbalances and this affects their daily lives; simple changes of being more conscious of how you move and use your body can go a very long way. Our daily posture, how we sleep, walk, lift anything, bend, and all other daily movements (or non-movement with sedentary lifestyle) will have a direct affect on our muscles and bone structure. It will take time and effort to gain strength back but it will pay dividends for the rest of your life!

If there's any pain (especially while preforming any specific movements) contact a PT right away! Thank you!
