Filter by:To analyze the relationship between composition of synovial fluid and its lubrication properties
Osteoarthritis (OA) is one of the most common diseases affecting the joints, usually those that are weight bearing such as the knees. OA is considered to be a disease of the cartilage in the joints even though it involves the whole joint, including the bone and synovium (thin lining of the joints which produces synovial fluid). With time, more and more of the cartilage is destroyed by the disease with inflammation commonly occurring. AS902330 is expected to increase the production and development of specific bone cells: chondrocytes and osteoblasts (cells that produce and maintain bone and cartilage). This is expected to lead to repair and regeneration of the cartilage, and a narrowing of the space width between the knee joints in a selected region of the knee.The purpose of this study is to see how safe treatment with AS902330 is, and to evaluate its effect on the knee cartilage. In addition, the study will also measure the effects of AS902330 in the blood.
Knee Osteoarthritis (OA) accounts for a significant proportion of mobility limitations and is one of the most disabling problems facing the growing population of older adults. The purpose of this research is to reduce disablement of older adults with symptomatic knee osteoarthritis.
The purpose of this study is to investigate the efficacy and safety of autologous transplantation of Bone Marrow Mesenchymal stem cells (MSCs) mixed with collagen I scaffold in patient with Knee cartilage defects and osteoarthritis

Barbed sutures offer several potential advantages in layered wound closure of hip and knee replacement surgeries. It use is gaining increased acceptance across many of the other surgical disciplines at this time. The purpose of this study is to evaluate the use of Quill as part of our layered closure compared to using our traditional sutures. The study timeline begins at the time of the surgical procedure and continues through the routine follow-up of total joint replacements at 2, 6, and 12 weeks, and will conclude at the six month post-operative office visit. Primary Objectives: - To evaluate the safety and efficacy of wound closure in primary hip and knee replacements using a bidirectional barbed suture (knotless) compared to a traditional layered (vicryl) wound closure. Secondary Objectives: - Establish the all around (intra-operative and post-operative) cost-savings potential in using a knotless wound closure compared to that of a layered vicryl closure (our standard suture protocol). - Assess the overall cosmesis of the wound/scar as well as perceived presence of subcutaneous surgical knots, when using the knotless wound closure versus our traditional layered suture closure.
Physiotherapy plays an important part in rehabilitation after total knee arthroplasty. Even if this is a common practice, few studies have been performed on this issue. The prime aim of this study is to examine the effects of an ambulatory individualized task-oriented exercise program compared with current ambulatory physiotherapy(usual care)on activity performance and self efficacy beliefs in the time span 6 weeks to 3 months after total knee arthroplasty with a follow-up at twelve months. HO:Task oriented physiotherapy has better effect than usual care on activity performance and self-efficacy beliefs in the time span 6 weeks to 3 months after total knee replacement.
The purpose of this research is to determine if post-operative cognition will be better if the general anesthesia for surgery is done with an inhaled (gas through a breathing tube) or intravenous (medicine injected in the IV) general anesthetic technique.
Project summary: Background: Computer navigation in knee replacement surgery is increasingly being used around the world, but the documentation of its usefulness is lacking. In order to critically evaluate this new surgical method, we want to perform a prospective, randomised clinical trial. Goal: We evaluate the need for these highly advanced techniques in knee replacement surgery, and the cost-effectiveness. Long term outcome for the patients will be predicted by using the radiostereometric analysis (RSA). Also, data from the Norwegian arthroplasty register will indicate any difference in long term survival of the implant. If there are any differences in the functional outcome or complication rate, between the two groups, this will be detected in this trial. Method: Patients age 50 through 85 years old, with gonarthritis, in need of knee replacement, are included in the trial. Radiostereometric analysis (RSA), CT-scans, X-rays, clinical evaluation score systems and laboratory measures are used in the evaluation process. A cost-effective analysis is performed based on data from Norwegian life tables, data from SINTEF and from the Norwegian arthroplasty register. Data from the Norwegian arthroplasty register will be statistically analysed separately for all knee replacements done with computer navigation in Norway in the last 5 years. Four Norwegian hospitals will collaborate in this trial (Haukeland university hospital, Haugesund hospital, Haugesund sanitetsforenings hospital for rheumatic diseases and Lovisenberg diakonale hospital) and patients are recruited from all four hospitals. Scientific impact/challenges: This trial will probably have great impact since good evidence supporting the use of computer navigation in knee surgery is lacking. It is important for the patient to be confident that he/she receives the best treatment, and it is important for the health care providers and funding authorities to have clear evidence when choosing between two different treatment techniques, in order for the patient to benefit.
Specific Aims: 1) To examine differences between AA and white patients with knee OA in willingness to consider knee joint replacement. 2) To examine the relationship between socio-cultural factors and patient willingness to consider joint replacement. 3) To examine how demographic, socio-cultural, and clinical factors mediate the relationship between race and patient willingness. 4) To examine the relationship between patient willingness and referral to orthopedic care for knee OA (secondary aim). Experimental design/Methodology: A cross-sectional survey study design will be used to examine socio-cultural and clinical factors that may vary by race/ethnicity and may be determinants of willingness to consider joint replacement as a treatment option. Patients with symptomatic and radiographic knee OA from the primary care clinics will be surveyed. Only individuals with knee OA of sufficient severity that would be considered candidates for joint replacement will be included. Analytic strategies include ordinal logistic regression, path analysis, and regression trees. Subject population: The study sample will consist of approximately 133 African American and 419 white patients with OA of the knee in a primary care setting.
