When functionality, affordability and aesthetics merge

Polycentric Knee

High-quality standards

Our products are CE-marked and ensure high technical performance, durability and adaptability to local conditions and diversified needs.

Customizable to everyone

The Circleg One is modular and therefore adjustable individually to each user, with both above- and below-knee amputations. The foot and knee components are customizable with the use of a few tools, simplifying the adjustment and alignment process for P&O specialists, and drastically reducing the working time.


Creating value locally

The Circleg One is designed and engineered with circularity in mind to eliminate waste, re-circulate materials, and regenerate nature. We manufacture our products in Kenya to improve the long waiting times, inefficient and costly procurements and logistical challenges of our customers. Local production and assembly further improve the maintenance and repair of used parts, thus increasing the longevity of our prosthetics and reducing costs for our beneficiaries.

Closing the loop

The Circleg One is designed to be fully recyclable. With each cycle, we’re using fewer virgin materials and protecting the earth’s resources.


When the old prosthetic parts are returned, we grind them, melt them down and reuse 100% of the material.


The prosthetic components are manufactured with simple and on-site available production methods.


The assembled components are distributed to local hospitals, NGO’s, health centers and prosthetic workshops in the region.

Fitting & Adjustment

The Circleg components are individually adapted to the users by P&O specialists in the respective health centers.

Use & Repair

The Circleg One is now ready for use. Thanks to its modularity, individual parts can be easily maintained, repaired and replaced.


Broken parts are collected and returned to the material cycle in order to produce new Circleg components.


Co-creation for the win

We designed and engineered the circleg prosthesis in close collaboration with acclaimed experts, academia and industry partners. But more importantly, with amputees and P&O specialists in both, Switzerland and the East African region. This interdisciplinary collaboration has allowed us to create a product that complies with the standards outlined by the EU MDR while fulfilling the needs of both users, P&O specialists and amputees.
