The Knee Therapy Blanket can reduce pain and soft tissue swelling as a result of surgery or trauma. It offers increased insulation to the user's knee for optimal temperature distribution and comfort. The attached straps give a more snug fit to ensure precise placement of the therapy blanket. This non-sterile version comes large in size. It is to be used with the JetStream Hot and Cold Therapy Unit (sold separately) for effective hot and cold therapy treatment.
