Low mobility solutions

The Terion K2 provides an ideal mechanical solution in conjunction with the Prosedo.


The 3R31 Prosedo knee joint allows low mobility amputees to regain their ability to stand and walk short distances. The joint provides targeted support for sitting down with the added benefits of security and comfort. When you disengage the lock, a high resistance is initiated.

  • Who can use the Terion K2 prosthetic foot?

    The Terion K2 is a prosthetic foot for people with low to moderate mobility (MOBIS 1 ‒ 2) who would like to maintain their mobility in everyday life. It supports the user with a high level of safety and adequate dynamic response. Thanks to its low weight, the Terion K2 is very comfortable and offers perceptible wearer comfort for getting around in everyday life, both at home and in the vicinity.

  • In what ways does the Terion K2 differ from conventional prosthetic feet?

    Unlike conventional prosthetic feet like the SACH and Dynamic feet, the Terion K2 features a combination of carbon fibre glass with a foam heel. This enables dampening and comfortable heel characteristics without having to forgo extended forefoot dynamics.

  • Can the Terion K2 prosthetic foot be used as part of an above-knee prosthesis?

    Yes! The Terion K2 is suitable for all amputation levels meeting the structural height requirements. It works with the Prosedo mechanical knee joint and the Kenevo microprocessor-controlled knee joints.

  • Do I need a new prosthesis to use the Terion K2?

    No, the Terion K2 can be integrated into new as well as existing modular prosthesis systems without any problem, provided sufficient structural height is available. The built-in adapter serves to securely connect the prosthetic foot.

  • Do I need to wear special shoes with the Terion K2?

    No, the Terion K2 is delivered with a footshell that is based on the shape of a natural foot, and works with most commercial footwear. The split toe of the footshell also allows you to wear sandals and flip flops.

  • Are Terion K2 prosthetic feet waterproof?
