Loughborough University is renowned for its strong emphasis on engineering and technology, which perfectly aligns with my research on finite element analysis of ankle fusion surgery. The University’s focus on interdisciplinary research has provided me with the opportunity to collaborate with experts in biomechanics, engineering and orthopaedics to create innovative approaches to improving surgical outcomes.
Additionally, the University offers a variety of engaging activities that have complemented my academic journey. For example, this year I participated in the No Bell Prize competition and achieved second place in the 3-Minute Thesis competition. These experiences have significantly enhanced my research work and helped me refine my ability to communicate complex ideas effectively.
My PhD project aims to understand the biomechanical changes within the body following ankle fusion surgery using finite element analysis. This understanding will guide improvements to the surgical procedure, optimise post-operative recovery, and minimise patient suffering. Moreover, a comprehensive finite element model of the foot and ankle can be used to simulate a wide range of scenarios, from common to extreme, providing foundational guidance for injury prevention and the optimisation of treatment strategies.
Ankle fusion surgery is considered the best solution for treating severe ankle conditions but the procedure can sometimes fail or result in non-healing.*
Although many researchers focus on understanding the biomechanical changes within the ankle joint, this area of study remains challenging due to the inability to directly experiment on living subjects. Some studies use cadaver ankles to simulate surgery, but due to limitations in sensor technology, this method has inherent constraints and potential inaccuracies.
By using finite element models of the foot and ankle that are created and validated from CT or MRI scans, we can simulate various surgical techniques and investigate changes in biomechanical parameters under different load conditions, such as walking, running, and jumping. These valuable insights provide an opportunity to distinguish between beneficial and adverse biomechanical changes.
Finite element models also allow us to fine-tune surgical techniques to identify optimal approaches without relying heavily on cadaver samples. We hope to further improve ankle fusion surgery through this method, providing theoretical support for post-operative recovery and alleviating patient suffering.
My advice for anyone considering undertaking a PhD, keep your curiosity alive and maintain a spirit of exploration for the unknown world.
