Finite Element Analysis of Effects of Gender-dependent 3d Knee Geometry and Joint Laxity on Acl Impingement against the Intercondylar Notch
نویسندگان
چکیده
Females demonstrated 2-9 times higher ACL injury rate, narrow notch width and higher joint laxity in multi-planar directions [1,2]. One of potential ACL injury mechanisms is ACL impingement against the lateral wall of the femoral intercondylar notch [3], expressed as elongated and deformed ACL geometry [3] and contact area and contact pressure between the ACL and the intercondylar notch [4]. However, it has remained unclear about the contribution of gender-dependent joint laxity and 3D knee geometry on the susceptibility of ACL impingement against the femoral intercondylar notch. The goal of this study was to investigate the effects of gender-dependent joint laxity and 3D geometry of the knee on ACL impingement against the femoral intercondylar notch using a validated knee finite element model [4].

Relationship between Femoral Intercondylar Notch Narrowing on Radiography and Anatomical and Histopathologic Integrity of Anterior Cruciate Ligament in Patients Undergoing Total Knee Replacement Surgery
Abstract Introduction: The presence of cruciate ligaments are very important for normal knee kinematics. Knee arthroplasty prostheses, in which these ligaments are maintained, have better kinematics. The aim of the present study was to investigate the association between femoral intercondylar notch narrowing in radiography and clinical and histopathologic integrity of anterior cruciate li...

OBJECTIVE A multifactorial combination of predictors may increase anterior cruciate ligament (ACL) injury risk in athletes. The objective of this twin study was to examine these risk factors to identify commonalities in risk factors that predisposed female fraternal twins to ACL injury. METHODS Female twins in high-risk sports were prospectively measured prior to an injury for neuromuscular c...
متن کاملA rationale for predicting graft impingement by the anterior cruciate intercondylar roof A magnetic resonance imaging study
This study was designed to analyze how anterior tibial tunnel placement can result in graft impingement by the intercondylar roof. The relationship of the ACL to the intercondylar roof was studied using magnetic resonance scans. An attempt was made to predict the amount of bone that may need to be removed from the intercondylar roof to prevent impingement on a 10 mm thick ACL graft. Magnetic re...
متن کاملInvestigating the Effect of Joint Geometry of the Gas Tungsten Arc Welding Process on the Residual Stress and Distortion using the Finite Element Method
Although a few models have been proposed for 3D simulation of different welding processes, 2D models are still more effective in design goals, thus more popular due to the short-time analysis. In this research, replacing "time" by the "third dimension of place", the gas tungsten arc welding process was simulated by the finite element method in two dimensions and in a short time with acceptable ...
