The Rigid Functional Knee Brace is a four-point functional knee orthosis designed to provide structured support for knee ligament instability, rehabilitation and controlled movement.
Its anatomically contoured rigid frame provides medial and lateral support around the knee while allowing functional knee movement. It may be used where additional stability is required following injuries involving the ACL, PCL, MCL or LCL, or during rehabilitation from an unstable knee.
Adjustable tool-less hinges incorporate interchangeable plug-in wedges that allow flexion and extension to be restricted where controlled range of motion is required. Where a particular movement range has been prescribed following injury or surgery, the hinge settings should follow the instructions provided by the treating healthcare professional.
Adjustable padded straps secure the brace around the thigh and calf, while a removable padded lining provides a soft interface against the leg. Anti-slip silicone detailing is designed to help reduce movement of the brace during wear.
Its relatively low-profile construction may allow it to be worn beneath suitable loose-fitting clothing. Separate Left and Right versions are available in sizes Small to X Large.
The brace may also be considered during a structured return to sport or activity following ligament injury where additional knee stability has been recommended. It should not be used to return to activity before the knee is ready.
Latex free.
