RISAn Optimized Image Matching Method for Determining In-Vivo TKA Kinematics with a Dual-Orthogonal Fluoroscopic Imaging System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study presents an optimized matching algorithm for a dual-orthogonal fluoroscopic image system used to determine six degrees-of-freedom total knee arthroplasty (TKA) kinematics in-vivo. The ...
Variability of a Three-Dimensional Finite Element Model Constructed Using Magnetic Resonance Images of a Knee for Joint Contact Stress Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Magnetic resonance (MR) imaging has been widely used to evaluate the thickness and volume of articular cartilage both in vivo and in vitro. While morphological information on the cartilage can ...
Determination of Optimal Graft Lengths for Posterior Cruciate Ligament Reconstruction—A Theoretical Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Various graft materials have been used in posterior cruciate ligament (PCL) reconstruction. However, it is unclear if these grafts can reproduce the structural behavior of the PCL. This paper ...
Relationship Between Three-Dimensional Geometry of the Trochlear Groove and In Vivo Patellar Tracking During Weight-Bearing Knee Flexion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is widely recognized that the tracking of patella is strongly influenced by the geometry of the trochlear groove. Nonetheless, quantitative baseline data regarding correlation between the ...
Estimation of In Vivo ACL Force Changes in Response to Increased Weightbearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Accurate knowledge of in vivo anterior cruciate ligament (ACL) forces is instrumental for understanding normal ACL function and improving surgical ACL reconstruction techniques. The objective of ...
The Coupled Motion of the Femur and Patella During In Vivo Weightbearing Knee Flexion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The movement of the knee joint consists of a coupled motion between the tibiofemoral and patellofemoral articulations. This study measured the six degrees-of-freedom kinematics of the tibia, ...
