Ice Packs for Knee Injuries Reusable, Gel Ice Wraps with Cold Compression for Injury and Post-Surgery, Plush Cover and Hands-Free Application, A Set of Two

Q: I'm having knee replacement surgery. How long will this stay cold? Is it recommended to buy additional packs?

This thing is lucky if it stays cold for 15 minutes. I have a similar one for the shoulder that I now have to strap around my knee that stays cold much longer. I put both in the freezer overnight and the shoulder pack, which is much thinner stays cold five times longer. I don't know how other people are getting anything more than 15 minutes out of this.

Q: Does the ice back reach the back of the knee also ? Because I usually ice both

I suppose it depends on how large your knee or leg is. My knee circumference going through the middle of my kneecap around is 16 inches and it does NOT go fully around. There is about a 3 to 4 inch gap in the back. I usually just rotate it and ice the back after or I put a small ice pack and strap it with the black straps attached to this ice pack. I do really like this ice pack though.

Q: Does this cool just the top of the knee or all around the back also?

Please note that we have launched a new and larger version of the Knee Ice Wrap which could wrap around the entire knee for most people. For more details, please search B09CPZS7J4 or REVIX XL Knee Ice Wrap on Amazon.

Q: What sizes are the knee ice packs? Do these fit all sizes?

This would fit all sizes because the bands are velcro and can be made tighter or looser as needed. My boyfriend has thanked me several times for getting this for him.
