Elferink, Amber (author)Moving through immersive virtual reality (VR) is commonly achieved by physically walking in the real room or using other techniques like an omnidirectional treadmill or walk-in-place. Roomscale walking is most similar to normal walking but is limited by physical space. However, other techniques can cause user experience issues such as VR...master thesis 2024

(author), Toksvig-Larsen, Sören (author)Aims The objective of this study was to compare the two-year migration and clinical outcomes of a new cementless hydroxyapatite (HA)-coated titanium acetabular shell with its previous version, which shared the same geometrical design but a different manufacturing process for applying the titanium surface. Methods Overall, 87 patients...journal article 2024

Klok, J.W.A. (author), Groenewegen, Jessica (author), Temmerman, Olivier (author), Van Straten, Niels (author), van Straten, Bart (author), Dankelman, J. (author), Horeman, T. (author)Objective: Cemented total hip arthroplasty (THA) demonstrates superior survival rates compared to uncemented procedures. Nevertheless, most younger patients opt for uncemented THA, as removing well-fixed bone cement in the femur during revisions is complex, particularly the distal cement plug. This removal procedure often increases the risk...journal article 2024

(author), Weinans, Harrie (author), Agricola, Rintje (author)Purpose Hip osteoarthritis (OA) is a major cause of pain and disability worldwide. Lack of effective therapies may reflect poor knowledge on its aetiology and risk factors, and result in the management of end-stage hip OA with costly joint replacement.

Nikita Gopakumar, Nikita (author)Hip replacement surgery, also termed total hip arthroplasty, is a surgical intervention intended to substitute a deteriorated or dysfunctional hip joint with an artificial prosthesis. This procedure is commonly indicated for individuals experiencing severe hip discomfort resulting from conditions like osteoarthritis, rheumatoid arthritis, hip...master thesis 2023

Mol, Tessa (author)Achieving appropriate soft tissue tension around the hip joint is an important factor for achieving hip stability after Total Hip Arthroplasty (THA). Hip instability leads to dislocations, pain, and is a common reason for early revision surgery. The current soft tissue tension assessments available during surgery rely on experience, and...master thesis 2023

Groenewegen, Jessica (author)Distal cement plug removal in total hip arthroplasty revision is a time-consuming and technically challenging procedure. There is a risk of perforating the femur while drilling in the cement plug. This risk increases when the orientation of the prosthesis tip is excentric. The aim of this study was to design a reusable drill guide that...master thesis 2023

A previously developed and internally validated clinical prediction model shows promise in identifying patients at risk of 90-day and 2-year mortality. Validation in an independent cohort is required to assess the generalizability;...journal article 2023

Barends, Jessica (author)Introduction: Revision total hip arthroplasty (THA) can be challenging in patients with severe acetabular bone defects and there is no consensus on the preferred reconstruction technique in this population. The aim of this study is to determine the biomechanical differences between Trabecular Metal Acetabular Revision System (TMARS) and Custom...master thesis 2022

(author)The success of total hip arthroplasty depends on the experience of the surgeon, and one of the ways the surgeon currently determines the final implant insertion depth is to listen to the change in audible pitch of the hammering sound. We investigated the use of vibration emissions as a novel method for insertion quality assessment. A non...journal article 2022

(author)Background: In hip arthroplasties, surgeons rely on their experience to assess the stability and balance of hip tissues when fitting the implant to their patients. During the operation, surgeons use a modular, temporary set of implants to feel the tension in the surrounding soft tissues and adjust the implant configuration. This process is...journal article 2022

Rietveld, Maxine (author)Trendelenburg gait is an abnormal gait that causes the pelvis to tilt downward during walking. The pelvis tilts downward above the unsupported leg, which is in the swing phase. Untreated, abnormal walking patterns can create the users to learn compensational movements and behaviours. As well as causing balancing issues when walking, it can also...master thesis 2021

(author), Weinans, Harrie (author), de Gast, Arthur (author), Dorr, Lawrence D. (author)Background: Anterior and posterior pelvic tilt appears to play a role in total hip arthroplasty (THA) stability. When changing from the standing to the sitting position, the pelvis typically rotates posteriorly while the hips flex and this affects the femoro-acetabular positions. This case-control study compares changes in 3-D acetabular cup...journal article 2021
