Cold therapy units, specifically designed for use after knee arthroplasty, circulate chilled water through a pad placed around the surgical site. This pad conforms to the knee’s contours, delivering consistent, targeted cold therapy. An example includes systems utilizing a motorized pump and cooler to maintain a specific temperature for extended periods.
Post-surgical application of cryotherapy reduces pain and swelling by constricting blood vessels and minimizing inflammation. This, in turn, can improve range of motion, facilitate faster recovery, and contribute to a more comfortable rehabilitation process. Historically, managing post-operative discomfort relied on less effective methods, such as basic ice packs. Modern cold therapy units offer a significant advancement by providing controlled, continuous cooling, essential for optimal healing after this common procedure.
