Abstract: A teletibial implant is provided for measuring forces between a femur having first and second condylar surfaces and a tibia when a joint is articulated. The implant includes a medial tibial insert engaging the first condylar surface and a lateral tibial insert engaging the second condylar surface. A transducer includes a medial plate coupled to the medial tibial insert, a lateral plate coupled to the lateral tibial insert, and a bottom plate supporting the medial and lateral plates. The medial and lateral plates receive forces from the medial and lateral inserts, respectively. The bottom plate also has a plurality of spaced apart force sensors for measuring forces exerted on the medial and lateral plates.
