I had jaw feminisation surgery with Cardenas a few years ago. I DO NOT RECOMMEND HIM. He did a very poor job, and now I need correction surgery but I would not risk myself to get surgery with him again, and he also wanted full price for corrective surgery, which he was also very reluctant to do! So I know you are asking about hip surgery, but if me and several others on here and other websites have complained about his poor performance related to FFS, you may think twice about considering his services. So you are welcome to PM me about my experience with him if you wish. BTW, a few months later I had orchi and t-shave with another surgeon in the same city and I am 100% satisfied with his work, but I really don't know if he does the hip implant thing, since this happened a few years ago and I have not contacted him since.
