Reason 1. It massages the part of your leg that never got "fixed": the thigh and calf around your new knee
Your surgeon replaced the joint. Nobody replaced the months of moving less. The muscles above and below the knee are the ones that feel heavy and tight by dinner.
The Comfort Ring straps right onto them and gives a gentle, steady massage while you sit still. Five levels, three modes.
Never on the knee. Never on the scar.
