of rotation) in the proximal and posterior directions. Stance phase flexion takes place against the
resistance of an elastomer spring. Stance phase extension is dampened by hydraulics.
Flexion and extension during the swing phase is controlled by two continuously variable hydraulic
valves.
An integrated extension assist supports the swing phase.
The vacuum pump in the prosthetic knee joint is part of a vacuum system that improves the con­
nection between the prosthesis and residual limb. An ischial containment prosthetic socket and
other components are needed as well.

1.2 Combination possibilities

INFORMATION
In a prosthesis, all prosthetic components have to meet the patient's requirements regarding the
amputation level, body weight, activity level, environmental conditions and field of application.
INFORMATION
Ottobock recommends using the product only in combination with socket systems that distribute
the vacuum over the largest possible area. The seal of the prosthetic socket should begin as
close underneath the socket entry section as possible. This ensures optimum control of residual
limb volume fluctuations.
Ottobock recommends the following socket system:
ProSeal Ring (452A1=*) with a textile-free liner (e.g. 6Y81 ProSeal Liner) and the 2R119
