Finite Element Modeling of the Tibiofemoral Joint

This biomechanics study develops a subject-specific FE model of the tibiofemoral joint using CT, MRI, and dynamic stereo-radiography to capture anatomical and motion data. The model accurately simulates cartilage stress and ligament forces under realistic gait conditions, offering valuable insight into joint function and clinical biomechanics applications.

CARTILAGE STRESS DURING WALKING IN OBESE AND NORMAL WEIGHT ADULTS

"DEVELOPMENT OF A HUMAN KNEE JOINT FINITE ELEMENT MODEL TO INVESTIGATE CARTILAGE STRESS DURING WALKING IN OBESE AND NORMAL WEIGHT ADULTS" This study uses a finite element model of the human knee to compare cartilage stress between obese and normal-weight individuals during walking. Results show that although the distribution of stress is similar, obese individuals experience significantly higher cartilage contact pressures, highlighting a mechanical link to osteoarthritis risk.

Biventricular finite element modeling of the acorn CorCap cardiac support device on a failing heart

This biomechanics-focused paper explores how different configurations of the Acorn CorCap Cardiac Support Device affect stress distributions and pump performance in a dilated heart. Finite element simulations demonstrated that the device effectively reduces end-diastolic fiber stress but may compromise pump function unless properly optimized. The results provide biomechanical insights that are critical for surgical planning and device design.

A FINITE ELEMENT STUDY ON THE MEDIAL PATELLOFEMORAL LIGAMENT RECONSTRUCTION

Bharath Koya

This biomechanics-driven finite element study evaluates the effects of graft fixation angles on patellofemoral joint mechanics following MPFL reconstruction. The findings underscore how surgical choices impact patellar tracking, contact pressures, and graft strain, emphasizing the need for biomechanically informed reconstruction strategies.

Subject-Specific Finite Element Modeling of the Tibiofemoral Joint In Vivo

Robert Edward Carey

This study develops and verifies a subject-specific finite element model of the tibiofemoral joint by combining MRI geometry with in vivo kinematic and contact data. The validated model simulates cartilage and ligament biomechanics during walking, offering critical insights into joint loading, tissue stresses, and clinical applications in orthopedics.
