The aim of this research was to prove the functionality of a smart tibial sensor for use during total knee replacements. The accuracy of such device provides surgeons with an objective tool for load balancing in the knee, where currently the joint is balanced based on the surgeon’s ‘feel’ of a balanced knee. Literature surrounding the kinematics and tibiofemoral joint forces through the flexion arc coupled with qualitative feedback from an orthopedic surgeon provided a basis for proving the functionality of the smart-sensor. Two full body cadavers underwent a cruciate-retaining total knee replacement using Zimmer’s Persona Knee System. Varying thicknesses adjusted the height of the tibial smart-sensor between 10 mm to 13 mm in increments of 1 mm. The contact points and loads were observed through the flexion arc (0°, 45°, and 90°). The results found similar results between the literature surrounding both the compartmental forces and contact points throughout the range of motion. Moreover, qualitative feedback determined that the smart-sensor was robust and durable throughout its use in both cadavers demonstrating its potential as a reusable device. Minor adjustments to the graphical user interface would improve the ease of use for the surgical team. This sensor demonstrated the functionality of the smart-sensor through cadaveric testing in predicating both the load and location throughout a range of motion. Continued development of this sensor would provide surgeons with an accurate and robust tool for intraoperative joint balancing which could extend to all joints in the body.
