I bought an ice machine, but it was a pain to keep refilling it. I did great with gel ice packs...they stay cold a long time. I really thought I'd love the ice machine, but ended up preferring the ice packs. MY LTKR was 6 months ago. Feeling great. It still hurts some, but they say it takes a year. Hoping to get the other knee done in a few months. I was worried sick about the first one, but it really wasn't that bad. Having help for a few weeks is essential tho.
Glad you are doing well. My neighbor had both of his knees replaced (at different times) and is loaning me his ice machine. The hospital may supply one (we will see) but I am not going to purchase one.
