BREG Polar Care Kodiak Cold Therapy System "The Breg Polar Care Kodiak Cold Therapy System is the most convenient and versatile offering in Breg's Polar Care line." Patients are required to bring to the hospital by orthopaedic surgeons for postoperative knee replacement surgery, at least in Vancouver and Victoria. I have had both knees replaced so certainly don't need it any longer.... unless things go wrong with my shoulders! :-)
