Cold therapy devices designed for the knee typically consist of a cuff or wrap connected to a cooling unit. This unit circulates chilled water or a refrigerant through the wrap, maintaining a consistent, therapeutic temperature on the affected joint. These devices are commonly used following surgery or injury.
Controlled cold application reduces pain and swelling by constricting blood vessels and slowing nerve conduction. This localized cooling can minimize inflammation and tissue damage, facilitating faster recovery. Historically, managing post-operative or injury-related knee pain and swelling relied on less precise methods like ice packs or frozen peas. Modern cold therapy units offer a more controlled, comfortable, and efficient alternative.
