Congratulations on such a weight loss. Good job. It is difficult to answer your question accurately without a physical examination nor pictures. However, based on your history, I do not think liposuction alone will fix your problems. I believe that your skin has been stretched out too much from weighing 22 stones. When you lost 8 stones, your skin tried to shrink around the fat that was lost from your inner thighs. However, your skin has only so much you elastic qualities. I do not believe by just removing excess thigh fat that your thigh skin will shrink wrap around your new thighs and you will wind up with smooth, smaller thinner thighs. Regardless of the expertise of your plastic surgeon, the type of liposuction machine used, and the type and length of compression used will significantly change the fact that you will probably need a medial thigh lift later.
With that said, it still may be worthwhile doing liposuction. Some reconstructive plastic surgeons perform liposuction several months ahead of a medial thigh lift anyway. This allows for debulking of fat and may lead to a better medial thigh lift final result.
If I were you, I would do the leg liposuction and see what everything looks like. Everyone is different and your results may be "acceptable" for you. However, based on your history, I believe your best results would be with a inner or medial thigh lift at a later date. Congratulations on your weight loss and good luck with your reconstructive plastic surgery.
