Cold therapy units, frequently utilized for post-operative or injury recovery, circulate chilled water through a pad applied to the affected joint. These devices offer a controlled and consistent method of delivering therapeutic cold to reduce pain and swelling. A typical unit comprises a reservoir for water and ice, a pump, and a connecting tube leading to a flexible pad designed to conform to the knee’s shape.
Controlling inflammation and pain is crucial following knee injuries or surgery. Cold application constricts blood vessels, minimizing swelling and reducing discomfort. Historically, basic ice packs or frozen peas served this purpose. Dedicated cold therapy units represent a significant advancement, providing sustained, even cooling over extended periods without the mess and inconvenience of frequently replacing melted ice. This consistent cooling promotes faster healing and improved patient comfort.
