So far I am very pleased with the purchase of my XL Hot Cold Therapy Reusable Knee Gel Ice Pack by Genie Enterprises.  It wraps around the circumference of my knee and the Velcro is very sturdy.  It is super cold too and holds the cold temperature very well.  It stayed in place very well when I had to walk-around with it on.
