Cold therapy units, frequently used after knee arthroplasty, deliver consistent, controlled cooling to the surgical site. These devices typically consist of a cooler unit, connecting tubes, and a pad or cuff that wraps around the knee. A pump circulates chilled water through the pad, reducing pain and swelling.
Post-operative inflammation and pain management are critical for successful joint replacement recovery. Controlled cold application minimizes swelling, reduces discomfort, and can improve range of motion. Historically, managing post-surgical inflammation relied on less precise methods like ice packs. Modern cold therapy units offer a significant advancement, providing consistent temperature control and reducing the risk of tissue damage from excessive cold.
