Polycentric                                          

• with integrated extension assist

• suitable for max. 100 kg body weight

Recommendation:

• for trans-femoral amputees

• with moderate functional levels

• medium stance phase stability

• medium swing phase control

• suitable also for hip disarticulation amputees

• not suitable for amputees with higher functional levels

Description:

Upper and lower joint section is connected with linkage bars. The stance phase stability is

achieved with the polycentric kinematic ( adjustment of the instant center of rotation by

adjustment of the stop). The stepless adjustment of the axis friction and of the extension

assist spring controls the swing phase.

Technical Data:

• Knee flexion range: approx. 120°

• Height (knee center - upper edge): 37 mm
