DEVELOPMENT OF A CONGRUENCE-BASED MUSCULOSKELETAL MODEL OF THE KNEE IN ANTERIOR CRUCIATE LIGAMENT INJURED ADOLESCENTS

Anterior cruciate ligament (ACL) injury rates are rising in adolescent populations [1]. In order to better understand how an individual’s joint morphology dictates their motion patterns, researchers have developed patient-specific musculoskeletal models using medical images of the tibiofemoral joint (TFJ) to study ACL injuries [2]. In particular, congruence-based modelling optimizes the configuration of the tibiofemoral joint to reduce pressure during movement [3], mimicking the mechanotransduction properties of articular cartilage [4]. However, these models have predominantly been constructed using adult knees, and it is unclear if patient-specific models can be developed for a growing population. Therefore, the purpose of this research is to build a patient-specific knee model for modelling passive knee joint motion during adolescence.
