Peak Knee Contact Forces Pre-to-post High Tibial Osteotomy and the Relationship to Peak External Knee Adduction Moments
Description
In this presentation, Jake Bowd discusses preliminary findings from his PhD research focusing on knee osteoarthritis and high tibial osteotomy (HTO). He introduces the topic by highlighting the prevalence of knee osteoarthritis in England and the risk factors associated with varus deformities. The main aim of his study is to determine if high tibial osteotomy can change knee contact forces and analyze the relationship between external knee adduction moments and simulated medial knee contact forces both before and after the surgery.
Bowd describes the computational modeling techniques employed in his research, utilizing the concurrent optimization of muscle activation and kinematics (COMAK) to simulate tibiofemoral contact forces during dynamic tasks. He explains the methodology involving three-dimensional gait analysis on patients undergoing HTO, with a focus on analyzing changes in knee contact forces post-surgery.
The results indicate a significant reduction in total contact force and medial contact forces post-surgery, while no changes in external knee adduction moments were observed. Bowd emphasizes the strong correlation between the external knee adduction moment and medial knee contact force both pre- and post-surgery.
Following the presentation, discussions ensue regarding the relationship between tibial osteotomy correction angle and peak knee contact forces, as well as validation of the SIMM model used for simulations. In conclusion, Bowd expresses gratitude for the opportunity to present his findings and opens the floor for questions.
