Last October 2012 I had a left total knee replacement then 5 months of physical therapy. The old gel packs I had at the time worked, but slid off my knee and got wet when they got warm. While visiting my brother and family in April 2013, I borrowed their Express Ice knee wrap (their twin daughters play softball) and really liked it so when I got home, I purchased one. Now I use it after recreating when my knee requires icing. The wrap stays on snugly and remains cold for a long time providing relief to swelling. Great product!
