Cold therapy units, specifically designed for the knee joint, offer a localized method of pain relief and inflammation reduction. These devices typically circulate chilled water through a pad applied directly to the affected area. An example of this technology is a system utilizing a reservoir, pump, and flexible cuff to deliver consistent cold to the knee. This focused application minimizes potential side effects from systemic cooling while maximizing therapeutic benefits.
Controlling post-operative or post-injury swelling and discomfort are key factors in the recovery process. Cold application can constrict blood vessels, minimizing fluid buildup in the joint and reducing pain signals. Historically, cold packs or ice have been used; however, these methods can be cumbersome and inconsistent in temperature delivery. Dedicated cold therapy systems provide more controlled and extended cooling, often with adjustable temperature settings to customize treatment and improve patient comfort during recovery.
