Plié 3

The FREEDOM Plié 3 knee is the world’s most reactive electronic knee; it responds 10 to 20 times quicker than the other microprocessor-controlled knees. It’s also water-resistant.

Its stumble and fall protection system lets users instinctively move at their own pace in any direction…even if it’s taking small short steps or turning round in confined spaces.

The FREEDOM Plié 3 knee is suitable for:

  • People with moderate activity levels who need a responsive custom-made knee capable of stopping them from stumbling when engaging in a variety of activities
  • Active or even very active people looking for a knee which lets them walk and run
  • At a range of speeds over uneven surfaces.
  • People whose hip has sufficient muscle strength in flexion and extension
  • Occasionally exposed to water

Based on many years of experience and on analysis of feedback from patients and professionals, the third version of the Plié has been further improved:

FREEDOM Plié 3 has more rugged internal components tested to ensure compliance with our rigorous standards for improved durability.

  • An improved flexion resistance bevel designed for durability

The new, intuitive software displays specific instructions to guide the prosthetist through the set-up process. The system features built-in gait and speed analysis to demonstrate variable cadence capacity to payors and referral sources

  • Controlled valve
  • 8 MHz microprocessor that reacts within 10 milliseconds
  • New bearings and electronic components for an even smoother gait
