ENGLISH
OH7/KH7 KNEE
The OH7/KH7 Knee is a polycentric knee joint with a stable aluminium frame construction. It is suitable for users
in mobility classes 3 and 4. The OH7/KH7 Knee is approved for a maximum body weight of 136 kg.

INDICATIONS FOR USE

The OH7/KH7 Knee is designed for patients with transfemoral and knee disarticulation amputation.
CONTRAINDICATIONS FOR USE
N/A.
Control of the swing phase is actively supported by an integrated, high-performance hydraulic system. Flexion and
extension can be adjusted separately by three valves to meet the needs of the user. The stance phase is secured by
the polyaxial construction. This offers a high degree of safety when walking and enables prosthesis alignment
without shortening.
Proximal adaptation can be achieved in a number of ways
• OH7 Knee with a pyramid adapter
• OH7 Knee with an IKF adapter
• KH7 Knee with a loop adapter
• KH7 Knee with a 3-arm socket adapter (particularly suitable for interim sockets)
For all adaptation options, the knee joints are infinitely adjustable by up to 5 mm in the AP/ML directions and can
be rotated without limitation (exception: IKF-Adapter). In addition, the flexion/extension angle and/or the
adduction/abduction angle of the KH7 Knee versions with loop adapter, can be corrected by up to max. 10° by
using the adjusting discs supplied. All the alignment adjustments can be carried out during the fitting phase or at
any other later point in time.
The OH7/KH7 Knee version with IKF adapter emulates the anatomical angle of strike of about 5 - 11° without
deactivating the safe knee joint geometry. Using the IKF adapter reduces stress on the joint chain and gives the
user a secure and energy-saving gait. The adapter also makes walking on gradual slopes and uneven ground
considerably easier and safer. A number of different progressive buffers are available that can be varied individually
depending on the walking habits of the prosthesis user. The IKF adapter can be used for all mobility classes.
