Knee model developed using new technology

Limbs & Things has always embraced new technology, and with advances in synthetic soft tissue materials the R&D team have re-developed a number of key products to incorporate this new technology. The latest edition, the new Knee for Aspiration and Injection, embraces state-of-the-art silicones and gels to provide an anatomically accurate representation of an adult right knee, both in terms of surface feel and underlying structures of ligaments, bone, muscle and fat.

Therapeutic procedures such as arthrocentesis and joint injections, can be practised in a safe environment away from the patient allowing for repeated needle insertion on both the lateral and medial sides of the knee. A key advancement in this product is that an echolucent material has been used to enable the use of ultrasound-guidance, as well as the more traditional blind technique.

“The development of the product demanded an innovative combination of materials, to ensure lifelike feel and the ability to ultrasound. The internal structure is anatomically accurate and is robust enough to withstand an impressively high volume of injections over several sites.”

Performing knee aspirations and injections are fundamental skills required for undergraduate and postgraduate medical study, and initial reactions in the field when demonstrating the model have been extremely positive, focusing on the improved anatomy and greater functionality.

During development the model was evaluated by professionals around the world, including Charles Wakeley (Bristol Royal Infirmary) and Andrew Grainger (Leeds Teaching Hospitals).

The Knee Trainer is available to buy via the Limbs & Things Website or directly with the offices in UK, US and Australia.
