The unilateral joint system

Orthosis joints for leg muscle paralysis

Optimised, harmonised system

The unilateral joint system from Ottobock provides you with a modern, harmonised and integrated leg orthosis fitting in case of paresis or paralysis of the leg musculature. It consists of a knee joint and ankle joint.

Depending on your individual physical condition, the unilateral joint system makes it possible to use only one knee and ankle joint respectively. This makes the orthosis especially light and comfortable to wear.

The ankle joint has a foot lifting effect and can be individually adapted to your needs by your orthopaedic technician thanks to its numerous adjustment possibilities.

Your technician can also equip the knee joint with an additional switch, so that you can set it to an open position for a limited time, for example to train on a therapy bike.

Locking mechanism

The lock lever makes it quick and easy to release and lock the joint with only one hand. A pull-release cable for unlocking can be installed if required.

Temporary switch

Your orthopaedic technician can install the switch in the knee joint if required. When you set the knee joint to an open position for a limited time, you can for example ride a therapy bike.

Multifunction ankle joint

The ankle joint has a foot lifting effect and can be individually adapted to your needs thanks to its various adjustment possibilities.



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.

Functionality

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°.
