Novel Robotic Control Methods That Account for System Compliance Decrease the Errors in Ligament Tensions Computed Using the Superposition Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Superposition testing is a method to quantify in situ ligament tension by measuring the change in joint loads before and after ligament sectioning. Despite its widespread use, the traditional robot control method ...
An Apparatus for Measuring Combined Shear-Tensile Loading in Fibrous Tissues Ex Vivo
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Soft tissues such as tendon and ligament undergo a combination of shear and tensile loading in vivo due to their boundary conditions at muscle and/or bone. Current experimental protocols are limited to pure tensile loading, ...
Characterization and Correction of Errors in Computing Contact Location Between Curved Articular Surfaces: Application to Total Knee Arthroplasty
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In total knee arthroplasty (TKA), one common metric used to evaluate innovations in component designs, methods of component alignment, and surgical techniques aimed at decreasing the high rate of patient-reported dissatisfaction ...
An Improved Tibial Force Sensor to Compute Contact Forces and Contact Locations In Vitro After Total Knee Arthroplasty
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Contact force imbalance and contact kinematics (i.e., motion of the contact location in each compartment during flexion) of the tibiofemoral joint are both important predictors of a patient's outcome following total knee ...
