Particle-Based Simulation of Bone to Optimize Implant Fixation Features for Fracture Minimisation

Description

In this presentation, Jennifer introduces herself and discusses her affiliations with Aztec and Lifespans. She presents findings related to cementless unicompartmental knee arthroplasty (UKA), highlighting the potential benefits of a fully additively manufactured UKA designed to improve fixation while minimizing the risk of bone fracture. Jennifer explains the risks associated with cementless implants, particularly for patients needing smaller implant sizes.



To optimize fixation features and reduce bone fracture risk, the team utilized particle simulation software to simulate bone behavior during the implantation of various implant designs in a proximal tibia. Multiple design variables were tested to assess their impact on bone damage, revealing that short keels, small diameters, and large peg taper angles significantly reduced fracture risks. The presentation concludes with the acknowledgment of the limitations of their study and emphasizes the effectiveness of particle-based simulations as a tool in implant design and development, opening the floor for questions.
