Dual-tray teletibial implant

A tibial implant for measuring forces between a femur having first and second condylar surfaces and a tibia when a joint is articulated, the implant comprising:

• a medial tibial insert engaging the first condylar surface;
• a lateral tibial insert engaging the second condylar surface;
• a transducer including:
• a medial plate coupled to the medial tibial insert and receiving forces from the medial tibial insert;
• a lateral plate coupled to the lateral tibial insert and receiving forces from the lateral tibial insert;
• and
• a bottom plate supporting the medial and lateral plates and having a plurality of spaced apart flexures deflectable for forces exerted on the medial and lateral plates, the flexures including separate flexures for each of the medial and lateral plates and a common flexure for both the medial and lateral plates.
