...B. Pereles; E. Tan; K. Ong There is a need to measure contact pressures at the femoral component and tibia plate of a knee arthroplasty implant to determine the wear and tear of the polyethylene (PE) insert of the implant. Today, most pressure monitoring systems for knee arthroplasty implants...

Thomsen To determine the wear behavior of knee endoprostheses, implants are tested in knee simulators before being introduced to the market. Implants may undergo mechanical failure and wear debris is generated. The magnitude...

... polyethylene insert is placed between the two components. The wear and tear of the polyethylene insert is considered a threat to the long-term survival of many knee implants. We have designed a wireless, implantable strain sensor to study the stresses experienced by the polyethylene insert. The sensor, which...
