The effects of mid-air adjustments on knee joint loading when landing from a jump
… of the most common injuries involving the knee joint is the Anterior Cruciate Ligament (ACL) tear. Female basketball and soccer players have about 3 times higher risk of ACL injury versus male athletes (Prodromos et al., 2007). Female athletes alter their motion pattern during the landing phase …

Quantitative Magnetic Resonance Imaging of Knee Articular Cartilage and Effusion-Synovitis: The Structural Response to Changes in Joint Loading
… condition that can affect all tissues within the joint. Methods to measure early changes in joint structures and the effect of interventions are required. The purpose of this thesis was to investigate aspects of quantitative magnetic resonance imaging (MRI) as outcome measures in knee OA studies. …

The effectiveness of a lateral wedge insole on knee pain, physical activity and joint loading in individuals with medial knee osteoarthritis
… of activity. Medial compartment of the knee joint is commonly affected, nearly 10 times more frequently, than lateral compartment by the disease. Knee loading (i.e. External Knee Adduction Moment (EKAM)) is higher in individuals with medial knee OA compared with healthy subjects. Lateral …

Quantitative Magnetic Resonance Imaging and Analysis of Articular Cartilage and Osteoarthritis
… recovery pattern of cartilage following acute joint loading could potentially present a more sensitive biomarker for defining cartilage health [1]. However, only a limited amount of studies have assessed both the immediate effect of joint loading on cartilage, as well as its post-loading …

Osteoarthritis Induced Glenoid Morphology and Bone Quality: An Evaluation of Augmented Glenoid Components
… augmented glenoid components underwent simulated joint loading using finite element analysis. Asymmetrically eroded glenoids were found to have denser bone (p

Assessment of knee extensor mechanism function and the manipulation of that function
… is believed to be related to changes ininternal joint loading as a result of alteration in the position and tracking of thepatellofemoral joint. One of the first challenges when assessing and treating thiscondition faced by the clinician is how to reliably and validly assess patella …

BIOMECHANICS OF THE DISTAL RADIOULNAR JOINT WITH A MALALIGNED DISTAL RADIUS
… biomechanics, specifically the kinematics and loading of the distal radial ulnar joint (DRUJ) before and after simulated distal radius malalignment would provide important new information to the treatment of these fractures. Furthermore, an investigation into the effect of soft- tissues would …

The Influence of Maximal and Submaximal Cyclic Concentric and Eccentric Exercise on Chondrocyte Death and Synovial Fluid Proteins in the Rabbit knee
Excessive joint loading has been associated with the onset and an increased rate of progression of osteoarthritis, but little is known about the effects of exercise loading on synovial fluid (SF) composition and chondrocytes viability. The purpose of this study was to load intact knee joints with …

Stress concentration around dowel bars in jointed rigid concrete pavements
… 3D Finite Element (3DFE) modeling of dowel jointed rigid pavement structures. Both straight and skewed joints were modeled using extremely fine meshing that allows accurate modeling of the friction and separation at dowel concrete interfaces. The model response was examined for the case of …

Development and Application of a BioRobotic Simulation of Stance Phase Gait to Study Foot and Ankle Kinematics
… a more complete parameter for characterizing joint motion. However, few studies have implemented this measurement to study normal, injured, or pathological foot-ankle biomechanics. Additionally, while load is suggested to play a major role in ankle biomechanics, including influences on …

Design and Prototype of an Active Knee Exoskeleton to Aid Farmers with Mobility Limitations
… because it reduces their physical strength, joint range of motion and is a source of joint pain, all culminating in the lack of ability to perform routine activities regularly and safely. One way to decrease the rate of injuries is by reducing the strength and joint loading required to …

Hip and Knee Biomechanics for Transtibial Amputees in Gait, Cycling, and Elliptical Training
… at increased risk of contralateral hip and knee joint osteoarthritis, likely due to abnormal biomechanics. Biomechanical challenges exist for transtibial amputees in gait and cycling; particularly, asymmetry in ground/pedal reaction forces and joint kinetics is well documented and …

Patient-Specific Musculoskeletal Modeling of Total Shoulder Arthroplasty
… debilitating pathologies of the glenohumeral joint such as osteoarthritis, humeral head fracture, and advancing rotator cuff tears. TSA replaces the articulation between the humeral head and the glenoid fossa, with the goals of relieving pain and restoring function. Two types of total shoulder …

Assessing Limb Symmetry using the Clinically Accessible loadsol®
… correlated with an increased fall risk, abnormal joint loading and decreased functional outcomes. Therefore, symmetry is focused on in the rehabilitation of many patient populations. Currently, load based symmetry is collected using expensive and immobile devices that are not clinically …

Biomechanical model of the shoulder joint
A biomechanical model of the glenohumeral joint has been developed to investigate muscle and joint loading during real life three-dimensional activities. Based on a rigid body mechanics approach, the model incorporates algorithms to correct for curved muscle paths and bone geometry, providing …

The Severity of Obesity and Knee Osteoarthritis: Effects on Strength and Gait
… of knee OA and their associations with abnormal joint loading, muscular weakness, knee pain, and function in older adults. METHODS: Baseline data from participants (n= 30) enrolled in the Fatty acids, Arthritis, and inflaMmation in the Elderly clinical trial were utilized for this study. Presence …

A Clearer Picture of Musculoskeletal Disorders of the Knee and Thumb Through the Lens of Image-Based Finite Element Analysis
… subchondral bone cysts (SBCs). The equine stifle joint provides a natural animal model for studying SBCs. Finite element models were used to examine three cyst sizes of approximately 0.03 cm3 (C1), 0.5 cm3 (C2), and 1 cm3 (C3) in the equine stifle joint. Fluid pressure was simulated by using a …
