IHN, Inc

IHN, Inc. manufactures the 3x10=0 Full Extension Knee Device, a specialized rehabilitation appliance designed for patients lacking passive knee extension following ACL reconstruction, total knee replacement, knee surgery, or trauma. The device uses a foam cushion and adjustable straps to gradually restore full knee extension through safe, prophylactic rehabilitation. Available in two configurations—standard and ankle-supporting versions—the 3x10=0 offers improved patient compliance compared to alternative day/night extension devices and can address long-standing extension deficits by extending application time. The device is simple to use, minimizing patient burden while supporting both knee and ankle stability to prevent thigh, leg, or foot rotation.
