Functional Highlights

• 
  Geometry: Long 4-Bar Polycentric Design.
• 
  Swing Phase: Pneumatic control system.
• 
  Alignment: A-P and M-L shifts (5mm).
• 
  Range: High flexion angle (155°).

The PN-200 series features a sophisticated Long 4-Bar Polycentric architecture, offering superior stability during the stance phase and shortening the leg length during the swing phase for better clearance. Equipped with a pneumatic cylinder and internal extension assist, it ensures a smooth gait cycle. The proximal adapter allows for precise Anterior-Posterior and Medial-Lateral shifts of 5mm, giving prosthetists exceptional alignment control.

The 4-bar linkage system moves the instantaneous center of rotation to optimize stability at heel strike. This design is particularly beneficial for K2-K3 users requiring confidence on varied terrain.

Unique to this model is the integrated slide adjustment capability. Prosthetists can shift the alignment 5mm in Anterior-Posterior and Medial-Lateral directions without additional components.
