same with the CPM (continuous passive motion) machine.
It's amazing to me how different protocols are from surgeon to surgeon. I was happy to pay any amount (practically), but my doc was "meh" on the GameReady and saw no need for the passive motion machine. Protocols are SO different that when I called the on-call ortho doc the weekend after my surgery, he wasn't able to answer the "day after operation" question I had because protocols vary!
Paying $75/day is kind of insane. Cold is cold. I'm sure an expensive recirc/cooler might be more consistently colder with no work. The ice/water method if using the cheap gravity system, you just empty and refill after 10 min. Or less. There's your compression release.
I have both the old cryocuff and the new one. The new one is a very small change to the existing system. The cooler needs to be a couple of feet above your knee, which in practice I found to be the biggest challenge. It squeezes and releases every few seconds, which both compressed the joint and forced the water back through the ice to bring in colder water. Obviously, you end up having to reload the ice in the cooler pretty regularly because it's being exposed to water that's gotten warmer. I will don't think there's any difference in the price between the squeeze system and the old one, but it would definitely be worth a couple hundred to me to get the compression effect. I have no idea of its efficacy per se, but it made my knee feel a lot better.
I never used the GameReady, so I can't speak to the differences. But if you were to injure yourself, I would definitely endorse getting the newer version of the Cryocuff cooler, even if you already have the old style.
