Unloader One– Knee Brace for Osteoarthritis Pain Relief The Unloader On is designed to relieve unicompartmental knee osteoarthritis pain and improve patient mobility. Using Össur’s patented 3-Point Leverage System, the brace combines a single hinge with dual Dynamic Force System™ (DFS) straps to unload the affected compartment, reducing pain and improving function. How Unloader Braces Work Unloader knee braces are designed to reduce pain from unicompartmental osteoarthritis by shifting pressure away from the affected side of the knee. Using a patented 3-Point Leverage System, the brace redistributes load across the joint to relieve discomfort and improve mobility. The thigh shell and calf shell provide two points of leverage. The Dynamic Force Strap (the diagonal strap above the knee) acts as the third point, “unloading” pressure from the painful compartment. This unloading effect can significantly reduce knee pain, making daily activities easier and more comfortable. Easy, On-the-Go Adjustability With the SmartDosing® dial powered by BOA® technology, you can fine-tune the level of unloading using just one hand. This on-the-fly adjustability helps you manage knee pain more effectively, whether at home, at work, or on the move.
