How Can I Correct my Skinny Legs?

At the risk of being stripped of my plastic surgeon credentials, I would spend the money on a trainer at the gym. Neither implants or fat grafting will likely give you the results you seek. A workout regimen focusing on your legs will give you better definition and more bulk.

Very good question.As you mentioned the two available options are implants & fat grafting. I have used both options. The implant option is a simple straight forward answer for a patient with unilateral leg atrophy.The muscle in the back of the leg was deficient and this was an ideal answer.Fat grafting works better for a circumferential correction (all around the leg); it requires more work, but it works well.

There is no good way to correct skinny legs except with exercise and muscle building.  Fat grafting and implants are not necessarily an ideal solution.
