Wildöer, David (author)To better understand and predict osteoarthritis, researchers are developing so-called coupled modelling workflows. Coupled workflows convert data from gait analysis studies to subject-specific tissue mechanical response estimations through the use of musculoskeletal and finite element models. The tissue mechanical response inside the joint is...master thesis 2022

Gevers, Imke (author)Background: Radiostereometric analysis (RSA) is a technique to assess early migration, which has a predictive value for early failure of unicompartmental knee arthroplasty (UKA). To successfully analyze the RSA images it is important to have a sufficient amount of visiblemarkers with an acceptable three-dimensional distribution.<br/>Objective:...master thesis 2022

Schijf, Menno (author)Introduction - Arthritis is a condition causing pain, deformations and loss of motion in human joints. The surgical instruments used to place a specific unconstrained prosthesis that is used to treat an arthritic joint are difficult to use. The objective for this thesis is to improve the current placement procedure by carrying out an analysis on...master thesis 2022

Waterval, N.F.J. (author), Brehm, M. A. (author), Harlaar, J. (author), Nollet, F. (author)Background: In individuals with unilateral plantar flexor weakness, the second peak of the vertical ground reaction force (GRF) is decreased. This leads to a higher ground reaction force, e.g. impact, of the contralateral leg, potentially explaining quadriceps muscle and/or knee joint pain. Energy cost optimized dorsal leaf ankle-foot...journal article 2022

An integrated in silico-in vitro approach for identifying therapeutic targets against osteoarthritisLesage, Raphaëlle (author), Ferrao Blanco, Mauricio N. (author), Narcisi, Roberto (author), Welting, Tim (author), van Osch, G.J.V.M. (author), Geris, Liesbet (author)Background: Without the availability of disease-modifying drugs, there is an unmet therapeutic need for osteoarthritic patients. During osteoarthritis, the homeostasis of articular chondrocytes is dysregulated and a phenotypical transition called hypertrophy occurs, leading to cartilage degeneration. Targeting this phenotypic transition has...journal article 2022

Harlaar, J. (author), Macri, E.M. (author), Wesseling, M.G.H. (author)Osteoarthritis (OA) has a complex, heterogeneous and only partly understood etiology. There is a definite role of joint cartilage pathomechanics in originating and progressing of the disease. Although it is still not identified precisely enough to design or select targeted treatments, the progress of this year's research demonstrates that...review 2022

(author), Hall, Michelle (author), Dekker, Joost (author), Lems, Willem F. (author), Harlaar, J. (author), van der Esch, Martin (author)Background: Muscle weakness is characteristic of knee osteoarthritis. Muscle steadiness may be an important adjunct to knee muscle strength in improving physical function in knee osteoarthritis. However, the role of muscle steadiness is uncertain. Aims: To determine the associations of knee extensor muscle steadiness with maximal voluntary...journal article 2022

Van Steen, Elien (author)During the course of this thesis, the design of a knee brace that improves the quality of life for people with arthritis in the knee, is being researched. The knee joint is covered with articular cartilage which protects the bones from being damaged. Arthritis of the knee is a pathology where this cartilage is damaged potentially even to the...master thesis 2021

(author), van der Esch, Martin (author)Background: Patients with knee osteoarthritis can adapt their gait to unload the most painful knee joint in order to try to reduce pain and improve physical function. However, these gait adaptations can cause higher loads on the contralateral joints. The aim of the study was to investigate the interlimb differences in knee and hip frontal...journal article 2021

Ferrao Blanco, Mauricio N. (author), Bastiaansen-Jenniskens, Yvonne M. (author), Chambers, Mark G. (author), Pitsillides, Andrew A. (author), Narcisi, Roberto (author), van Osch, G.J.V.M. (author)Objective: In osteoarthritis, chondrocytes tend to acquire a hypertrophic phenotype, which contributes to the modification of the extracellular matrix, resulting in permanent cartilage changes. In mouse chondrocytes, pro-inflammatory macrophages and pro-inflammatory cytokines have been shown to stimulate hypertrophy via the activation of the...journal article 2021

Schrijvers, Jim C. (author), van den Noort, Josien C. (author), van der Esch, Martin (author), Harlaar, J. (author)Knee joint instability is frequently reported by patients with knee osteoarthritis (KOA). Objective metrics to assess knee joint instability are lacking, making it difficult to target therapies aiming to improve stability. Therefore, the aim of this study was to compare responses in neuromechanics to perturbations during gait in patients with...journal article 2021

Wouda, Frank J. (author), Jaspar, Stephan L.J.O. (author), Harlaar, J. (author), van Beijnum, Bert Jan F. (author), Veltink, Peter H. (author)Background: The foot progression angle is an important measure used to help patients reduce their knee adduction moment. Current measurement systems are either lab-bounded or do not function in all environments (e.g., magnetically distorted). This work proposes a novel approach to estimate foot progression angle using a single foot-worn...journal article 2021

(author), Visser, Jetze (author), Brommer, Harold (author)To prevent the progression of posttraumatic osteoarthritis, assessment of cartilage composition is critical for effective treatment planning. Posttraumatic changes include proteoglycan (PG) loss and elevated water content. Quantitative dual-energy computed tomography (QDECT) provides a means to diagnose these changes. Here, we determine the...journal article 2021
