I used the O2 knee support after an arthroscopic knee surgery. It made me very comfortable to know that I had an easy way to apply the cold therapy that the doctor required.
I have a brace that I use for arthritis of the knee and I had been icing my knee at night. What a difference it was to add compression with the ice!! The O2 support is easier to use than an ice bag.
The O2 helped me after my shoulder surgery. The support felt best after I pumped it up.
