CDS Knee Brace Extension

Dynamic spring-loaded knee orthosis

CDS® Knee Brace Extension

Indications

  • Joint contractures:

- After surgery
- After conservative treatment of capsular ligament injuries
- Before and after joint replacement
- In arthrosis and chronic polyarthritis
- After burns
- After strokes
- After spinal cord injuries
- Paralysis (discrete palsy of peripheral origin)
- After cranio-cerebral trauma (CCT)

  • To prevent new contractures after arthrolysis
  • Rupture of a muscle fibre of quadriceps femoris
  • Patella tendon rupture
  • Extension deficit from weakness of quadriceps
  • Conservative and postoperative indications, where active extension of the knee is contraindicated

Features

  • Therapy in extension
  • New! Smaller hinge with established features:

- Individual adjustment of the spring tension
- Spring tension can be switched on and off without tools and without varying the set spring tension
- Infinitely variable adjustment of the redression range between -15° and +30°

  • New! Optimized shell - and strapsystem

- High wearing comfort thanks to air-permeable, light aluminium shell elements
- High flexibility thanks to adjustable shell elements

Mode of Operation

The CDS® Knee Brace Extension functions according to the CDS®-principle and has been designed to treat an extension deficit of the knee. The brace applies a dynamic low load prolonged stretch to stimulate growth in the contracted tissue. The adjustable redression range protects the tissue from painful overstretching and allows for individual extension until -15°.
