Product description


AS-KX-04 is very comfortable short brace to patellar lateral dislocation treatment. The brace is made of unique airy materials. The patellar support is provided by soft lateral pelotte, equipped with two independent circumferential straps attaching above and under the knee. Additionally, adjustable silicone pelotte sets patella properly.

While knee flexion or extension the circumferential straps cooperate with silicone pelotte and set patella properly what decreases knee pain.

Frontal part of the brace is made of perforated, non-elastic ActivePren™ which compress knee joint.


ActivePren™ is an active 3-layered fabric made of elastic jersey layer and perforated neoprene foam. This lamination is very soft and high elastic. Foam’s perforation improves the air circulation and maintains great skin’s condition. The skin can breathe freely and its required temperature is maintained because of AirSupply System. This material is not knitte, what prevents skin against the skin abrasions in the compression zones. Our braces, made of ActivePren are the most durable and provide the best stabilization in the market. WATERPROOF MATERIAL.

Back part is made of openwork elastic material called ProSix™, which is very thin what facilitates knee flexion during performance (e.g. in sport).


ProSix™ is an innovative fabric 3D, elastic in all directions and fitting to the limb precisely. External layer is 3D material providing excellent stabilization. There is duothermic spacer foam providing high air permeability and compression inside. The skin has contact with cotton that is breathable and soft. ProSix™ is friendly and neutral for the skin and has Oeko-Tex Standard 100 certificate.

Clasps made of AirDistance III™ material.


AirDistance III™ is breathable durable lamination. Consists of 3 layers: external self-gripping polyamide, comfort foam inside and internal polyamide 3D fabric. This spacer fabric 3D provides high air permeability and minimal water and moisture absorption. Waterproof material.

To stabilize knee joint precisely we use additionally two spiral lateral stays.

Setting up

Setting up


Our orthopedic spiral boning is a thin wire, coiled into a spring and flattened. We use boning of various widths and wire thicknesses, which determines the strength of their stabilization. Each spiral boning has two specially profiled fittings to prevent damage of the orthosis. They are galvanically protected against corrosion by the galvanizing process, so they are resistant to water, moisture and sweat. Products equipped with bonings can be washed without removing them from the orthosis. They work in every direction, perfectly adjusting to the user's body and have a shape memory function, thanks to which they always return to their original profile. This function causes the spiral boning in the orthosis to stabilize the swollen limb immediately after the injury and after the swelling has come off.
