Sure! My orthopedic surgeon recommended 2 types: ones that circulate ice water, and ones that circulate ice water and can do compression at the same time. For the first type, there were a few options that you can find for purchase on Amazon. The ice water circulation + compression type machine, which is the one I used, is the GRPRO 2.1 from Game Ready and you lease the machine by the week.

The GRPRO is a bit more expensive (around $150/wk), but the results are worth it. I had minimal swelling overall, and any swelling after doing my exercises is resolved with a couple cycles on the GRPRO. The part that wraps around your knee is also larger than the ice water-only machines, covering mid-thigh to mid-calf, and provides better, more even/consistent icing.

Hope that helps!
