I have some fat around my knees. Could a non surgical treatment really help? (photos)

Recently I was advised to do Exilis and/or Accent but I am afraid to give £2000 for something that might not help much. What would you suggest please? I would really appreciate an honest reply about effective solutions. I was also told that fat-freezing is not applicable in my case. I would rather avoid lipo but if i knew for sure that I could see a difference with surgery in London where I am based, I would consider it. It is an area that really upsets me regrading my apperance. Thank you in anticipation
