Filter by:Over the last few years, it has been suggested that Knee Ostheoarthritis (KOA) incidence and progression could potentially be related to skeletal muscle characteristics. In particular, weakness of the quadriceps muscle would be a key determinant of KOA. However the mechanisms underpinning the influence of skeletal muscle in the pathophysiology of ostheoarthritis (OA) are poorly understood. Crosstalk between skeletal muscle and structures around and in the joint is of interest. In physical deconditioning and aging, it has been reported that skeletal muscle can be replaced by adipose tissue. Several factors involved in the development of OA but also of adipose tissue may be involved in these muscular changes. Of interest, in patients with KOA, quadriceps weakness is an ubiquitous clinical finding. Infiltration of adipose tissue in skeletal muscle has been shown to affect muscle strength and mobility and be linked to cartilage volume loss and the occurrence/progression of KOA. The main objective of this study is to compare the characteristics of the Hoffa tissus and the intamuscular fat (IMF) tissus in the quadriceps muscle in patients with gonarthrosis requiring total knee prosthesis. This is a single-centre study based on a collection of surgical waste and is categorized as Research Not Involving Human subjects.
Osteoarthritis (OA) is the most prevalent form of arthritis. Its pathogenesis remains poorly understood. Though historically regarded as a disease of mechanical degeneration, it is now appreciated that inflammation plays an important role in OA pathogenesis
The purpose of this study is to compare the effectiveness of percutaneous electrotherapy treatment with transcutaneous and placebo.
This project aims to evaluate the effects of an evidence-based training program in combination with an antiinflammatory dietetic intervention on quality of life for patients with knee osteoarthritis
Rationale: Osteoarthritis (OA) is mainly characterized by cartilage degeneration. In knee OA, measuring the distance between the tibia and femur, known as the joint space width (JSW), is an often-used method to quantify the progression of the disease or the effectiveness of treatments, because it is an indirect measure of cartilage degeneration. However, JSW is often measured while the patient is standing (weight-bearing) with slightly flexed knees, with a flexion angle of around 7-10 degrees, while direct cartilage thickness measurements are usually performed while the patient is lying down (non-weight-bearing) with an extended leg [1]. Because of this difference in positioning, it is difficult to compare different JSW and cartilage thickness measures, as it is not clear what happens with the JSW distribution in the joint when a patient changes position between weight-bearing/non-weight-bearing and flexion/extension. In this study, we aim to identify the changes that occur in the knee of OA patients under the influence of weight-bearing and/or flexion, to enable comparing joint space measures from different positions. In this research we want to use MRI as a three-dimensional imaging technique because there is no radiation involved.. Objective: To evaluate how the 3D knee joint space distribution in knee OA patients changes under the influence of weight-bearing (upright) and flexion MRI scanning. Study design: Explorative cross-sectional study. Study population: 21 patients with symptomatic knee osteoarthritis (Kellgren-Lawrence grade 2 or 3) are included from the orthopaedics department of Medisch Spectrum Twente in Enschede. Main study parameters/endpoints: The primary study parameter is the change in medial joint space width between the different positions (weight-bearing/non-weight-bearing and flexion/extension).
This study aims to determine if baseline measures of psychology and pain sensitivity can predict changes in physical function at 1 year in patients with knee osteoarthritis.
The goal of this study is to establish the efficacy of an intervention of dietary weight loss, exercise, and weight-loss maintenance for knee Osteoarthritis (OA) prevention in adult females aged ≥ 50 years with obesity and no or infrequent knee pain. The primary aim is to compare the effects of a dietary weight loss, exercise, and weight-loss maintenance to an attention control group in preventing the development of structural Magnetic Resonance Imaging (MRI) knee OA. Secondary aims will determine the intervention effects on pain, mobility, health-related quality of life, knee joint compressive forces, inflammatory measures, weight loss, exercise self-efficacy, and cost-effectiveness of this intervention.
Knee arthroplasty is a successful surgical treatment for end-stage osteoarthritis. Most patients are satisfied with the result, however, 10% of the patients have remained dissatisfied over the last decades despite the advantages of the surgical procedure. Previous studies suggest that rehabilitation needs to be individualized and that some patients request additional support. Patient empowerment is a patient-centered strategy to increase, amongst other, patient engagement, participation, and motivation. Patient empowerment can be defined as a "process that helps people gain control over their own lives and increases their capacity to act on issues that they themselves define as important". One way of increasing patient empowerment is through motivational interviewing. Motivational interviewing is an evidence-based approach in which patients are supported to identify behavior changes toward their own individual goals. The aim of this study is to investigate if motivational interviewing could increase satisfaction in patients undergoing knee arthroplasty. Furthermore, we want to examine role MI in this patient group with interviews of both MI-practitioners and patients as well as detailed investigations about the MI sessions.
As the United Kingdom's National Health Service (NHS) waiting list soars above seven million people, with treatment wait times over two years, older people with chronic conditions face worsening symptoms, increased use of medications, more complicated surgeries with slower recovery, reduced quality of life, and loss of independence. As part of its plans to tackle this crisis, the NHS promotes exercise as a "miracle cure" for arresting the progress of disease and helping disease management and recovery. However, current plans promoting individual, home-based exercise, as well as on-site hospital-based programs of delivery, have met with only limited success, and face problems of decreased space, capacity, clinician time, as well as lack of knowledge and expertise with regard to effective behavior change. We have developed a community-based group exercise programme for older people with hip osteoarthritis. This community-based group exercise programme has successfully helped those with hip osteoarthritis (3.5 million over 45s in the UK) reduce pain and need for medication, as well as avoiding surgery, and has formed part of an NIHR trial examining the use of exercise and education versus standard physiotherapy care for the treatment of hip osteoarthritis. In order to better understand the mechanisms of action of this programme, the present study will examine, via focus groups interviews, the experiences of participants who have undertaken the exercise and education programme. The data generated from the focus groups will help to elucidate what "works" within the programme and will help inform future development of resources to support health professionals in providing exercise rehabilitation for older people with chronic conditions.
The aim of this feasibility trial is to investigate the feasibility of a trial intervention for a population of patients after total knee replacement for osteoarthritis. This study follows a hybrid type 1 design where the primary focus is on the feasibility of the intervention, and the secondary focus is on gaining a better understanding of context and acceptability. The main questions it aims to answer are: - Recruitment (Process/Resources): Are patients willing to engage, and stay, in the trial (estimated by inclusion-rate, participant retention, etc.) and what reasons do patients give for not wishing to enroll or later dropping out of the trial? (inquired face-to-face, during enrolment). - Harms (Scientific): Does the non-exercise intervention appear "safe" (i.e. not harmful) for the patients? (estimated by for instance: adverse events, reasons for dropouts and sense of security). - Trial procedure feasibility (Management/Scientific): How well does recruitment and trial procedures work at trial sites? (estimated through feedback from site personnel). - Participant (patient) experienced acceptability of their assigned intervention: An interview-based follow-up using the Theoretical Framework of Acceptability. Participants will be randomized to one of two interventions, at discharge from the hospital, following knee replacement, which are being tested for feasibility: 1. "Usual-care" - referral to municipal (free-of-charge) physiotherapy (commonly 6-8 weeks of therapeutic exercise). 2. "Return to everyday life" - no referral to municipal physiotherapy. Participants in both groups are encouraged to follow WHO guidelines of physical activity, to the degree that their post-surgical symptoms allow (within their orthopedic surgeon's recommendations/limitations). All participants are given a "symptom guide", meaning a folder containing information on what to expect, and when and what to react to, during their recovery after the knee-replacement. For clarity it should be mentioned, that the quantitative and qualitative data-outputs will be reported separately for improved clarity (the study is not a mixed methods design).
