The unilateral joint system

Benefits at a glance

Comfortable to wear

Instead of two knee and ankle joints respectively, just one of each can be used up to a body weight of 110 kg. This depends on your individual physical condition in each case. This makes the orthosis especially lightweight, slim and comfortable to wear.

Lightweight and stable

A special titanium alloy gives you a noticeable advantage in terms of weight, with no loss of stability.

Always the right size

The joint system is available in different sizes, including size versions especially for children.


The unilateral joint system consists of a locked knee joint with wedge lock and a multifunction ankle joint. While the knee joint is permanently locked, it can be unlocked using a lock lever or pull-release cable, for example when you want to sit down. The joint engages automatically when you get up and is therefore locked again.

The ankle joint has a foot lifting effect and makes it possible for your O&P professional to adjust the joint to your individual needs thanks to its various combination options as well as the continuously variable limitation of the range of motion up to a maximum of 20°.
