protect.4 OA

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

Indications

conservative treatment of advanced unilateral osteoarthritis or complex ligamentous instability, particularly in combination with 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

4-point rigid knee orthosis for control of anterior and posterior tibial translation. Protection, stabilisation, pain relief and restoration of mobility by:
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 which often causes osteoarthritis
safeguards against hyperextension and offers limitation of flexion and extension

Features

exact and effective valgus or varus pressure exerted close to the knee joint
wide, well cushioned frame padding for the 3-point pressure relief system
malleable frame design to reduce torsional forces
ultraflat, very light weight and non protruding frame and hinge construction
pressure relief of the medial or lateral hinge compartment by the 3-point principle which off-loads the knee into a varus or valgus position
stabilisation of the knee by the 4-point system to counteract knee instability which often causes osteoarthritis
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
