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 he 4-point principle to couteract knee instability which often causes osteoarthritis
- safeguards against hyperextension and offers limitation of flexion and extension
Features
- exact and effective valgus or varus pressure close exertedto 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 ad 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
