RISJoint Coordinate System Using Functional Axes Achieves Clinically Meaningful Kinematics of the Tibiofemoral Joint as Compared to the International Society of Biomechanics Recommendation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Quantification of clinically meaningful tibiofemoral motions requires a joint coordinate system (JCS) with motions free from kinematic crosstalk errors. The objectives were to use a JCS with literature-backed functional ...
Agreement Between Two Methods for Computing the Anterior–Posterior Positions of Native Femoral Condyles Using Three-Dimensional Bone Models With and Without Articular Cartilage and Smoothing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Knowledge of anterior–posterior (AP) movement of the femoral condyles on the tibia in healthy knees serves to assess whether an artificial knee restores natural movement. Two methods for identifying AP positions and hence ...
Design and Accuracy Evaluation of a Depth Gauge-Referencing Guide System for Measuring Articular Cartilage Thickness on the Distal Femoral Condyles During Unrestricted Kinematically Aligned Total Knee Arthroplasty
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Regardless of pre-operative deformity, unrestricted kinematically aligned (unKA) total knee arthroplasty (TKA) seeks to restore the native femoral joint lines which requires that the thickness of articular cartilage be ...
Optimized Design of an Instrumented Spatial Linkage that Minimizes Errors in Locating the Rotational Axes of the Tibiofemoral Joint: A Computational Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An accurate method to locate of the flexionextension (FE) axis and longitudinal rotation (LR) axis of the tibiofemoral joint is required to accurately characterize tibiofemoral kinematics. A method was recently developed ...
Design, Calibration and Validation of a Novel 3D Printed Instrumented Spatial Linkage that Measures Changes in the Rotational Axes of the Tibiofemoral Joint
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An accurate axisfinding technique is required to measure any changes from normal caused by total knee arthroplasty in the flexion–extension (F–E) and longitudinal rotation (LR) axes of the tibiofemoral joint. In a ...
