44, female - please recommend a treatment to remove cellulite around & above knee & tighten the skin (Photos)

I'm an active 44 year old female. I am trying to find the best treatment for my cellulitis legs and to tighten. I don't want liposuction but another treatment. There are so many options and I get confused on which one is the best for me. I am 5'11 and weigh 140 pounds but my legs have pockets of fat and I hate wearing shorts. Please help!
