Functional Knee Orthosis for Stabilization of the Knee Joint

Indications

• Conservative
– Functional treatment of cruciate and lateral ligament injuries
– Severe and/or complex instabilities
– Support for the affected compartment in varus/valgus arthritis

• Postoperative MOS Genu short
– After ligament surgery / ligament reconstruction
– Meniscal suture and meniscal implantation

• Postoperative Mos Genu is long
-After Tibial Osteotomy (Tibia)
– After complex reconstruction of ligaments
– For fractures near the joint, implant surgery and protection in individual cases

• MOS-Genu short / long (with waist belt)
– Genu recurvatum

Features

• The aluminum frame has an anatomical design and can be reshaped if desired.
• Designed as a long version, the frame construction can easily be converted to standard length by removing the extension clips.
• The clip bumpers are made of breathable, sweat-proof, non-slip, skin-friendly material and are used safely with orthosis Velcro ties.
• Monocentric joints are adjusted with the Nietert compromise pivot axis, allowing extension and flexion to be restricted in 10° intervals.
• Condylar tampons of different thicknesses can be used to compensate for varying degrees of knee joint swelling.
• In cases of posterior instability or genu recurvatum, an optional popliteal band is used to stabilize the knee.

Mode of Action

• The knee orthosis is based on the 4-point principle and eliminates the effect of the anterior pull phenomenon.
• Varus/valgus adjustment provides targeted relief in the knee compartment and lateral ligament by adapting the patient to a different leg axis.
• The orthosis design allows the knee to be stabilized against varus/valgus forces. The long version has a longer arm.
• The popliteal band eliminates stress on the orthosis hinges by preventing hyperextension.
• Dorsal pressure exerted by the popliteal band counteracts the effect of the posterior puller phenomenon.
• Possible straining forces applied to the knee joint by the orthosis are minimized by adapting the orthosis to monocentric hinges.
