Modern plastics technology used in leg prosthetics creates the basis for the new 3R41 knee joint. The next generation of traditional locking knee joints offers additional advantages.



Above knee amputees with very low activity level requiring a particularly high degree of stability benefit from simple handling of the innovative release mechanism that can be initiated also under partial load condition.
Innovative locking mechanism
In full extension the innovative locking mechanism secures the joint automatically whereas engaging of the lock latch can be heard and felt. The joint is released either by pulling the cable or by pushing the lock latch (patella). Designing this knee joint special importance was attached to a balanced relation between release power and prosthesis load to offer even more safety during operation.
Modern plastics technology
Plastic materials make the joint particularly lightweight, wear-resistant and easy to maintain. In addition it is resistant against moisture and splash water offering the user increased flexibility.
Functional design
Modern design offers functional advantages. The anterior plastic cap avoids finger injuries as getting caught in the joint gap and protects the cosmetic foam cover.
Movable pyramid
The proximal adjustment pyramid can be moved in A/P-direction to allow adaptation of prosthetic alignment or compensation of hip flexion contracture.
