Unused G2 rehab knee brace (left leg - I think can use for either though). Post surgery rehab allows for increase or decrease of knee flexion. This is unused because the one I had was warrantied and by the time the replacement came my rehab was over. Low-profile ROM hinge can be locked at 0° to 100° Simply rotate and quick-lock flexion/extension settings ROM control in 10° increments:Flexion 0° to 120°, Extension 0° to 100° Telescoping design for tool-free length adjustment from 20.5" – 27.5"
