Knee

Our purpose was to develop a fully instrumented tibial component of a total knee prosthesis (Fig. 1) containing multichannel transducers (load cells), a microtransmitter, and an antenna. Three complex technologies were incorporated into a prosthesis capable of measuring in vivo tibiofemoral compressive forces to transmit “real-time” data. The geometry was modified to accommodate the transducer and electronic technologies (Fig. 2).
