protect.4 OA

Off-loading knee orthosis for control of anterior and posterior tibial translation and varus/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

  • 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
  • stabilisation of the knee joint by the 4-point principle to counteract instability which is often associated with osteoarthritis
  • prevents hyper-extension and offers limitation of flexion and extension

Features

  • precise and effective valgus or varus pressure exerted across the knee joint
  • wide, cushioned frame padding for the 3-point pressure relief system
  • malleable frame design to reduce torsional forces and ultra-flat, light weight frame and hinge construction
  • pressure relief of the medial or lateral compartment by the 3-point principle which off-loads the knee into a varus or valgus position
  • extension limitation at: 0°, 10°, 20°, 30°, 45°
  • flexion limitation at: 0°, 10°, 20°, 30°, 45°, 60°, 75°, 90°, 120°
  • immobilisation at: 0°, 10°, 20°, 30°, 45°
  • under sleeve and knee guard available on request
