Quadricep Weakness

Depending on the severity of instability due to quad weakness, the patient will benefit from the Icarus Ascender knee brace or Hercules KAFO. Both devices provide unique assistance that supports extension and prevents buckling of the knee. It directly assists the quadricep while the muscle heals, allowing the patient to continue their activities. For more severe cases of instability due to quad damage, the patient may benefit from the additional knee and ankle support provided by the Hercules KAFO, which provides up to 60 lbs of extension assist, and can use a Tension Lock system to lock the patient’s knee at extension. These devices reduce fall risk and may support healing by unloading the quadricep.
