Orthosis for the correction and stabilisation of the knee joint
• The aluminum frame is anatomically contoured and can subsequently be reshaped as required.
• The long version can readily be converted to the standard length by removing the extension shells.
• The shell pads are equipped with a breathable, nonslip, skin-friendly coating.
• The monocentric joints are aligned with Nietert’s compromise pivot axis and permit restriction of extension and flexion in 10° intervals.
• Condylar pads of differing thickness can be used to compensate for knee swelling of varying severity.
• An optional popliteal strap is used to stabilize the knee in the event of posterior instability or genu recurvatum.
Mode of action
• The Varus / valgus adjustment relieves the relevant knee compartment
and / or the collateral ligament according to the 3-point principle.
• The knee orthosis is based on the known 4-point-Principle and thus counteracts the anterior drawer phenomenon.
• The frame construction stabilizes the knee joint against varus / valgus forces; the long version has a longer lever arm.
• The popliteal strap takes the strain off the orthosis hinges by preventing hyperextension.
• The dorsal pressure exerted by the popliteal strap counteracts the posterior drawer phenomenon.
• Possible constraining forces exerted by the orthosis on the knee are minimized through adaptation of the frame to the monocentric hinges.
Support for the affected compartment in cases of
varus / valgus osteoarthritis of the knee
Rupture of the anterior and / or posterior cruciate ligament (ACL / PCL)
Severe and / or complex instability (traumatic, degenerative;
e. g. “unhappy triad”)
Collateral ligament injury
To restrict the range of movement of the knee
(e. g. after meniscal suturing or meniscal implantation)
Genu recurvatum (with cross-strap)
Complex ligament reconstructions
Fractures located close to joints, implant surgery and protection
(conservative and post-operative)
