Finite element analysis of the knee joint: a computational tool to analyze the combined behavior after treatment of torn ligaments and menisci in the human knee joint.

Article Synopsis
- Finite element analysis (FEA) is crucial in orthopaedics for simulating and analyzing surgical procedures, revealing that removing over 20% of the meniscus significantly raises shear stress in cartilage and heightens knee joint degeneration risk.
- Meniscal root repair can enhance meniscal biomechanics and lower osteoarthritis risk, even with non-ideal repairs, while FEA helps to study the biomechanics of knee ligaments, showing that certain graft techniques closely mimic native knee function.
- Incorporating lateral augmentation techniques can enhance stability in ACL and PCL repairs, and there is a need for future studies to integrate patient-specific anatomical and mechanical data for better experimental models.
The aim of this study is to compare the diagnostic performance of magnetic resonance imaging (MRI) against computed tomography (CT) in various aspects of local staging in colon cancer patients. This study was a prospective single arm diagnostic accuracy study. All consecutive adult patients with confirmed colon cancer that met the current criteria for surgical resection were considered as eligible.

Materials And Methods: A systematic literature search was conducted in Embase, Medline and Web of Science, for studies evaluating ADC values and ADCratio for PCa diagnosis, using the same patient cohorts and using histopathological references as ground truth. Pooled sensitivities, specificities, summary ROC curves and AUCs were calculated from constructed contingency data tables.
Purpose: The anatomy education literature suggests blended-learning approaches as more effective. We performed a literature review to answer the question if virtual dissection tables can play a significant role as supplements to traditional cadaver-based anatomy education methods.
Methods: PubMed, SCOPUS, ERIC and Cochrane databases were searched for articles with purpose to explore the outcomes of the use of virtual dissection tables in conjunction with cadaver-based anatomy education.
