Abstract
Disclosed herein are joint implants with sensors and methods for assembling joint implants with sensors. A knee implant according to the present disclosure can include a femoral implant configured to be coupled to a femur and a tibial implant configured to be coupled to a tibia. The tibial implant can include a tibial insert disposed between the femoral implant and a tibial baseplate of the tibial implant. The tibial insert can include at least one sensor and a battery disposed within a void of the tibial insert, and a detachable case configured to seal an opening of the void. The detachable case can be configured to seal the opening of the void by engaging one or more projections with one or more corresponding recesses of the tibial insert.
