Mechanical Design Optimisation of a Tibial Insert for use in Instrumented Total Knee Replacement

This PhD research has presented guidelines on how to design, manufacture, and test a smart knee implant. The aim of this PhD research was to investigate how to modify a conventional tibial insert design to incorporate sensors and electronic components whilst ensuring patient safety. Several manufacturing methods were developed to address manufacturing and assembling challenges. Computational and experimental studies were carried out to analyse the structural strength, wear performance, and safety of a modified tibial insert. Additional experimental studies were performed to illustrate the feasibility and practical applications for making measurements with embedded sensors. Previous studies on instrumented tibial inserts did not address manufacturing limitations nor safety concerns.
