Telemetric Implants Provide “Inside” Look at Impact of Shoes

Amber Blake

What if something as simple as selecting the right footwear could improve the prognosis for individuals with knee osteoarthritis (OA)? Two members of the Orthopaedic Research Society (ORS)—Prof. Georg Bergmann and Prof. Georg Duda of the Julius Wolff Institut, Charité–Universitätsmedizin, in Berlin—are trying to determine whether picking the right shoe can make the difference between comfort and worsening joint pain.

Their ‘Loading and Movement’ team wants to learn what effect different footwear has on knee joint loading. The team has developed special instrumented implants for the hip, shoulder, knee, and spine. These implants are based on total joint replacement implants currently in wide clinical use. The implants have been modified to include sensors and a telemetry system. To date they have implanted nearly 50 patients with these devices.
