We used one of these when my stepmom had her knee replaced & was reduced to crying non-stop in post-op PAIN & so BAD that she was refusing to DO the Post-Op PT regimen. She SLEPT for 4 hours within 20 minutes of using this thing with VERY cold water in the tank. We would SWEAR it cut her pain perception in HALF! Please consider it for anyone you LOVE who's had to undergo joint replacement! Terry H
