Upper support

The upper support is a contoured structure that fits around the thigh (quadriceps region). It features lateral slots for securely attaching straps to fasten the brace to the upper leg.
This component stabilizes the upper part of the rehabilitative knee brace, ensuring proper alignment and anchoring on the thigh. It helps distribute the forces evenly across the quadriceps, enhancing the knee's support during movement or rehabilitation exercises.
The support is positioned on the thigh above the knee. Straps are threaded through the lateral slots and tightened to secure the brace. It works in conjunction with the lower support to provide comprehensive stability.


Lower Support

The lower support is designed to contour around the calf region below the knee. It also includes lateral slots to facilitate strap attachment and secure fastening.
Purpose: This component provides stability and support to the lower portion of the knee brace, ensuring proper fixation around the calf. It aids in maintaining the knee's alignment during motion and helps manage any stress transferred from the knee joint.
Usage: The support is placed on the calf, below the knee. Straps are inserted through the slots, then adjusted and tightened to hold the brace firmly. It complements the upper support to provide a secure fit and overall stability for the knee brace.


Brace Hinge

The ratchet hinge is a mechanical component designed to allow controlled angular movement of the knee brace. It consists of interlocking teeth that engage to permit unidirectional or limited bidirectional movement. The hinge can be adjusted to restrict or allow movement at specific angles, providing stability and controlled mobility to the knee joint.
The ratchet hinge is essential for providing adjustable support and controlled articulation in a rehabilitative knee brace. It ensures proper stabilization of the knee during recovery while allowing the gradual restoration of movement, which is critical for regaining full functionality after injury or surgery.
The hinge is positioned on the lateral and medial sides of the knee brace, aligned with the natural axis of the knee joint.
It is adjusted to set the desired range of motion, depending on the patient’s rehabilitation stage.
During weight-bearing activities, the hinge locks at a pre-set angle to support and prevent hyperextension or undue stress on the knee. As rehabilitation progresses, the range of motion can be incrementally increased by adjusting the hinge, facilitating a gradual transition to unrestricted knee movement.
