Draw & Doodle Simulation: A colorful strategy to prepare medical teams for electronic dance music festival emergencies.

Educational Challenge: Electronic dance music (EDM) festivals - crowded, loud, low-resource environments - pose unique challenges to event medical teams. Simulation can prepare teams to manage clinical presentations in this unconventional context. Without access to simulation infrastructure, a low-technological, low-fidelity simulation modality is warranted.

Biomechanical analysis of ligament modelling techniques in TKA knees during laxity tests using a virtual joint motion simulator.

Total knee arthroplasty (TKA) is an end-stage treatment for knee osteoarthritis that relieves pain and loss of mobility, but patient satisfaction and revision rates require improvement. One cause for TKA revision is joint instability, which may be due to improper ligament balancing. A better understanding of the relationship between prosthesis design, alignment, and ligament engagement is necessary to improve component designs and surgical techniques to achieve better outcomes.

Virtual Joint Motion Simulator Accurately Predicts Effects of Femoral Component Malalignment during TKA.

Component alignment accuracy during total knee arthroplasty (TKA) has been improving through the adoption of image-based navigation and robotic surgical systems. The biomechanical implications of resulting component alignment error, however, should be better characterized to better understand how sensitive surgical outcomes are to alignment error. Thus, means for analyzing the relationships between alignment, joint kinematics, and ligament mechanics for candidate prosthesis component design are necessary.

Posterior-stabilized total knee arthroplasty kinematics and joint laxity: A hybrid biomechanical study.

Background: Posterior-stabilized (PS)-total knee arthroplasty (TKA) arose as an alternative to cruciate-retaining (CR)-TKA in the 1970s. Since then, it has become a popularly utilized TKA design with outcomes comparable to CR-TKA. The post-cam mechanism is unique to PS-TKA as it substitutes the function of the posterior cruciate ligament (PCL).
