If you're recovering from knee surgery or dealing with knee pain, this large cold therapy pad can make a huge difference in your comfort and recovery. Measuring 14x15 inches, it's big enough to cover your entire knee area for effective cold therapy. It comes with three independent elastic straps (each 3x27 inches) that keep the pad securely in place without you having to hold it. There's also a non-woven liner included for hygiene and comfort. The pad has a transparent polyether PTU front and heat-insulating sponge cloth back to keep the cold where it belongs. It uses a standard 1/4 inch hose barb connector that works with most cold therapy machines (just double-check your machine's compatibility). Whether you're dealing with post-surgery swelling, arthritis flare-ups, sports injuries, or general inflammation, regular cold therapy can really help reduce pain and speed up healing. The large size makes it much more effective than those small ice packs, and the straps mean you can actually move around a bit while using it. Much more comfortable than holding a bag of frozen peas on your knee!
