Genu Arexa

Guarantees therapeutic success

An operation is usually unavoidable after a ligament injury in the knee, such as tearing of the anterior cruciate ligament. The Genu Arexa knee brace optimally supports each phase of the healing process after surgery but also during conservative treatment without an operation. It not only prevents undesirable movements, but also restores your safety and confidence in your own mobility. Furthermore, it permits a controlled transition from your first steps after the operation to full weight bearing. The knee brace can also be worn at night and during physiotherapy exercises.

Why do doctors, O&P professionals and patients rely on the Genu Arexa? Because it is easy to use: its self-adapting plastic shells perfectly mould themselves to the shape of the user’s leg the first time the brace is worn, and numbered straps make it simpler to put on and take off. Plus, it features a user-oriented, multiple award-winning design and can be easily adapted without any tools.

Knee support for cruciate ligament tears

How does a cruciate ligament tear occur?

The anterior cruciate ligament often tears during abrupt braking movements where the knee is flexed, curved slightly inward and simultaneously rotated outwards (valgus stress). This type of injury is particularly common when skiing and playing football. The posterior cruciate ligament, on the other hand, tears less frequently and mostly due to powerful external forces.

Therapy after a cruciate ligament tear

The Genu Arexa knee brace is a device for the conservative follow-up treatment of cruciate ligament injuries such as distensions, partial ruptures or ruptures. It is used for injuries to the anterior and the posterior cruciate ligaments as well as the medial and/or lateral collateral ligament. While it is intended primarily for functional follow-up treatment after ligament reconstructions, it is also used for the conservative therapy of chronic, complex instabilities of the knee joint.
