Cold therapy units, frequently employed after surgical procedures, deliver consistent, controlled cooling to specific body areas. For example, following a knee replacement, a device circulating chilled water through a pad wrapped around the joint can minimize swelling and discomfort.
The application of controlled cold to surgical sites offers several advantages. Reduced inflammation, pain management, and potential decrease in the need for pain medication are key benefits. This practice has evolved from basic ice pack application to sophisticated systems offering precise temperature regulation and targeted compression, improving patient comfort and recovery outcomes.
