An affordable and durable prosthetic paediatric knee

Project Status: 

The CSIR is developing a low-cost prosthetic device to improve the lives of paediatric amputees. While numerous prosthetic knee options are available for adults in low-resource areas, the options for children in these contexts, are limited.

Current paediatric prosthetic solutions are mainly aimed at children living in first-world environments. Lower-cost options imported from other low-resource countries are still unaffordable to many amputees in South Africa, and are of inadequate design and made of non-durable materials.

The CSIR prototype uses durable materials that offer a long-lasting, safe and low-cost solution to young amputees. In addition, a motion-detection device is attached to the paediatric knee to monitor the leg movement of amputees over time. This allows healthcare practitioners to monitor the general health of amputees.

In addition, the device is able to measure the pressure inside an amputee’s prosthetic socket to detect areas of high pressure. Early detection is vital for the prevention of pressure sores, preventing further possible amputation. Work is currently being done to qualify the device as an ISO 13485-certified product through international auditors.
