The Functional 4-Point Knee Brace is a rigid functional orthosis designed to provide high-level stability for ligament injury and complex knee instability.
Its lightweight aluminium-alloy frame uses a four-point support principle to reinforce the knee while maintaining a relatively low-profile anatomical fit around the thigh and lower leg.
Flat polycentric hinges on either side of the joint allow knee movement to be controlled using the supplied settings. Extension can be limited at 0°, 10°, 20°, 30° or 40°, while flexion can be limited at 45°, 60°, 75° or 90°. The knee can also be immobilised at selected positions where this forms part of a rehabilitation programme.
An adjustable foam strap system secures the frame above and below the knee and allows the fit to be adapted around the leg. Removable anti-slip interior padding provides a soft interface between the rigid frame and the skin and can be removed for cleaning.
The brace may be suitable for ACL, PCL, MCL or LCL instability, combined ligament instability, complex knee instability and selected pre- or post-operative rehabilitation.
It may also be considered where structured ligament support is required during selected sporting activity, provided the injury and stage of rehabilitation are appropriate for return to activity.
Separate Left and Right versions are available.
Where the brace is being used following surgery, significant ligament injury or where range-of-motion restriction is required, hinge settings should follow the advice of the treating healthcare professional.
