M.4^®s OA

4-point knee orthosis for control of anterior and posterior tibial translation.
3-point off-loader for varus or valgus pressure relief.

Indications

conservative treatment of complex ligament instability, particularly in conservative treatment of advanced unilateral osteoarthritis
post-operative pressure relief and compartmental protection after fractures of the tibial head, cartilage surgery, meniscus refixation, correction osteotomy
instability of the cruciate ligaments with pressure relief of the medial or lateral compartment
for functional pre- or post-operative care of knee instabilities

Mode of action

Protection, stabilisation, pain relief and restoration of mobility
pressure relief of the medial or lateral joint compartment by the 3-point principle which off-loads the affected compartment into a varus or valgus position
stabilisation of the knee joint by the 4-point principle to counteract knee instablity, a cause of osteoarthritis.
safeguards against hyperextension and offers limitation of flexion and extension

Features

'S' profile improves torsional stability whilst following natural alignment of femur and tibia
hinges proximal to knee joint allow precise off loading of the knee polycentric hinges
anatomically premoulded frame
strong, low profile, light weight frame and hinge construction
numbered straps ensure a simple fastening sequence
air condyle pads with skin-grip system
excellent comfort with new soft-grip padding material
extension limitation at: 0º, 10º, 20º, 30º, 45º
flexion limitation at: 0º, 10º, 20º, 30º, 45º, 60º, 75º, 90º, 120º
immobilisation at: 0º, 10º, 20º, 30º, 45º
under sleeve and knee protector available
