Active clinical trials for "Osteoarthritis"

This study aims to investigate the shoulder function of patients with osteoarthritis or a fracture of the upper extremity after surgery with the Global Unite shoulder system. The majority of fractures of the humerus are non-surgically treated, but for the complex cases where the fracture is irreparable (1), the treatment choice is a shoulder prosthesis called a hemiarthroplasty. Hemiarthroplasty has been associated to less pain and more quality of life , (2,3) but no difference in range of motion is reported when compared to non-surgically treatment of complex humeral fractures. (2,3,4) One of the important steps in surgery of a fractured humerus is the fixation of the bone fragments in an anatomically correct position as previous studies have shown that complications related to the fixation and healing of bone fragments occurred in 11 % of patients treated with a hemiarthroplasty . The Global Unite hemiarthroplasty introduces a new feature, which allows the surgeon to more closely attach the bone fragments. Patients with osteoarthritis and fractures of the humerus will be included from two hospitals, Herlev and Køge University Hospital. A total of 88 patients, 44 osteoarthritis and 44 fracture patients, are included. The patients will be followed two years after surgery and will be seen a total of four times postoperatively, where the function of the shoulder will be examined by questionnaires concerning shoulder function and quality of life, by a motion examination and by x-ray. The outcome of these examinations will be compared to the functional outcome of patients that have received different shoulder prostheses for the same diagnoses at Herlev and Køge University Hospital. The patients will undergo two radiographic scans after surgery, to determine whether or not bone fragments remain in an anatomically correct position in the patients with a fracture of the proximal humerus. A special focus will be on the function of the shoulder in patients with bone fragments that are not in an anatomically correct position. Furthermore, complications and the need of reoperation were registered during the two-year follow-up period. The aims of this study is to Determine the function of the shoulder in patients receiving the Global Unite prosthesis due to either osteoarthritis or fracture of the humerus. To compare these results with results from patients previously treated with a different prosthesis designs To determine the influence of the fixation of bone fragments in the postoperative function in fracture patients.

The objective of this prospective study is to determine (1) the time course of patient-relevant functional outcome evaluated by the Knee injury and Osteoarthritis Outcome Score (KOOS) and (2) the time course of range of motion (ROM) the first four years following TKR using the LCS rotating platform prosthesis. Improvement of patient self-reported pain and daily function during the study period, are of particular interest.

The purpose of this study is to describe the 3D joint biomechanics of the lower extremities of patients having had a total hip replacement or hip resurfacing surgery as compared to a healthy age and weight matched control group during level walking, stair ascent and descent, and entering and exiting the front seat of a car.

The purpose of this study is to evaluate reverse total shoulder arthroplasty patients preoperative objective measurements and operative objective measurements to determine if there is any effect to postoperative outcomes. Patients who were 18 years old or greater at the time of surgery were followed clinically and radiographically to determine best practice and optimal treatment and technique, risk and rate of complication, and postoperative outcomes.

Osteoarthritis is an evolving joint disease caused by degeneration of bones and cartilage, with significant personal and social impact. Osteoarthritis of the knee is the most common type of osteoarthritis, affecting up to 19% of adults (aged 45 and over) according to recent studies. The costs associated with the management of osteoarthritis involve not only direct treatment strategies (clinical evaluations, drugs, prostheses, surgery), but also significant indirect costs (loss of productivity) The severity of knee osteoarthriris symptoms and the types of interventions are highly variable. There are surgical and nonsurgical treatment strategies. The replacement of the knee joint by a total prosthesis is a surgical choice for severe knee osteoarthritis which currently represents the basic treatment. However, a large proportion of patients with knee osteoarthritis can not or do not wish to have surgery, either because of the unavailability of the choice of surgery, or the disability and post-operative pain that can be caused by surgery. Since surgery is not always the preferred or available treatment for people with knee osteoarthritis, it has been shown that acting on modifiable risk factors (severe obesity) can significantly reduce the pain and disability but it is not always sufficient. Other effective therapeutic osteoarthritis strategies include biomechanical interventions, intra-articular injections like corticosteroids ; anti-inflammatory and analgesic drugs, exercise, patient education and bodybuilding. There is also an innovative strategy that is under development and consists of the use of nanostructured and functionalized implants for bone and cartilage regeneration. The objective of this study is to carry out a medico-economic study centered on knee osteoarthritis management strategies. At a time when the decisions of management of pathologies must be based on the efficiency of the possible therapies, and given the high prevalence of knee osteoarthritis, it appears crucial to carry out this type of study in order to 'bring elements to public health decision makers. In addition, there is a demand for medico-economic assessment of osteoarthritis management strategies emerging in the literature. To carry out this study, we plan to carry out an extensive review of the literature on relevant non-surgical strategies for patients with moderate and severe knee osteoarthritis and for whom total knee replacement was feasible. This will aim to extract data to develop a modeling (Markov models) of knee osteoarthritis management by different therapeutic strategies. At this stage, the cost and quality of life data for the models will be searched in order to be linked to the strategy cost within a medico-economic evaluation. If the literature proves to be insufficient, the use of the data of the University Hospitals of Strasbourg (retrospective study), the realization of an epidemiological study (prospective study) will be a possible in order to make the model.

Osteoarthritis (OA) is the most common joint disease in the world and induces major physical, psychological, societal and economic burdens. The management of osteoarthritis is complex. Viscosupplementation by local injection in the arthritic knee is a validated therapy used after failure of conventional analgesic treatments and non-pharmacological modalities. The size effect of this treatment is modest between 0.3 and 0.6. We do not currently have any predictive criteria for the effectiveness of this treatment. The procedure tested in this research is the characterization of synovial fluid (SF) by an in vitro Raman microspectroscopy technique. The results obtained will make it possible to compare the effectiveness of visco-supplementation with hyaluronic acid from the Hyalgan© trade according to classic criteria in the literature.

This study will attempt to draw relationships between the soft-tissue related complications contributing to early TKA revision and the loading and positional patterns from intraoperative tibial trial sensors. The data from the sensors may enable the surgeon to address such soft-tissue abnormalities that may otherwise be unknown during traditional total knee revision procedures. The utilization of sensors should in theory, help diagnose the potential causes attributing to soft-tissue imbalance and may lead to a decreased need for an all component revision. Furthermore, the economic implications from converting a total revision to a partial revision could have a profound effect to the patient and healthcare provider such as decreased rehabilitation regimes and opportunity for cost savings. Eligible revision patients who agree to participate will be followed for a period of 12 months following the revision procedure. Patient reported outcomes measures (PROM) such as the 2011 Knee Society Score (KSS) and the Veterans Rand 12-Item Health Survey (VR-12) will be collected at baseline (pre-operatively) and at 6 weeks, 6 months and 12 months post-procedure. All outcomes will be scored to observe changes from baseline at 12-months. Cost-analyses of sensor-assisted revision TKA will be performed to include OR costs, facility and physician fees, as well as payments to post-acute collaborators such as SNFs, rehab hospitals, PT and home care providers. A quantitative analysis of commercial payer claims / usage data (e.g., CMS Medpar data) will be used to examine costs associated with traditional revision TKA procedures.

Glucosamine is an important part of the treatment strategy for osteoarthritis, but its effectiveness is still controversial. To explain the efficacy differences of glucosamine, in this study the investigators detect the concentration of glucosamine in the plasma and synovial fluid, some effect indexes such as inflammatory markers and gene polymorphism of glucosamine transporters. On the one hand, the investigators compare the plasma peak and gluten glucosamine concentration and the concentration in synovial fluid among participants to observe the individual differences of glucosamine exposure in vivo. On the other hand, the investigators investigate the correlation between drug concentrations, effect index and gene polymorphism. The hypothesis is that glucosamine exposure in vivo has individual differences and gene polymorphism can explain this differences.

This is a substudy to a randomised trial investigating the effect of liraglutide on body weight and pain in overweight or obese patients with knee osteoarthritis (NCT02905864). In the parent trial, patients will be subjected to an 8-week diet intervention phase including a low-calorie diet and dietetic counseling, after which patients will be randomised to receive either liraglutide 3 mg or liraglutide 3 mg placebo as an add-on to dietetic guidance on re-introducing regular foods and a focus on continued motivation to engage in a healthy lifestyle. This substudy aims to investigate any changes in the thickness of Adventitia, Extra-media (EMT) and veia jugularis assessed by ultrasound in relation to an initial 8-week weight loss intervention. Change will be assessed by grey-scale ultrasound, the area measured will be from the anterior wall of arteria carotis interna to the jugular vein including the wall of the vein, subsequent the thickness of the artery will be subtracted to measure the thickness of the of Adventitia, Extra-media (EMT) and veia jugularis interna compelx.
