Active clinical trials for "Osteoarthritis"

The purpose of this study is to determine whether the nutritional supplement ARTRONAT improves the quality of life of patients with osteoarthritis.

This postmarketing study was conducted to describe prescribing patterns for etoricoxib (ARCOXIA®) in General Practice and describe the incidence of selected adverse events recorded in the United Kingdom (UK) Medicines and Health Care Products Regulatory Agency (MHRA) General Practice Research Database (GPRD).

This is a follow-up study looking at the and long-term results of two methods of preparing the thigh bone to receive an implant during hip replacement surgery. For one group of patients in the original study, the surgeon used a cutting tool called a broach and a special hammer on patients who had standard hip replacement operations. For the other patients, the surgeon used a surgical robot which was equipped with a cutting tool, like a drill, to prepare the thigh bone. The purpose of this study is to collect additional information confirming that the surgical robot is safe and effective when used as recommended. Only patients who were enrolled in the original clinical trials are eligible for this study.

New anticoagulants are being introduced to replace warfarin. These drugs do not require monitoring and are safer. There is currently no recommended way to reverse these drugs rapidly in the event of undue bleeding or need for emergency surgery. This is a lab study to look at ways to reverse the drugs rapidly

Impact of loss of weight on knee arthrosis has not been thoroughly studied. The primary goal of this study is to compare the MRI parameters (aspect of cartilage and oedema of spongious sub-chondral bone) before and one year after bariatric surgery. Knee MRI is not currently part of the investigations preceding bariatric surgery.

Osteoarthritis is by far the most common joint condition and the single largest cause of disability in the older population. The investigators still have a poor understanding of the nature of osteoarthritis and factors that influence its development and progression. Identification of biochemical markers that relate to cartilage loss, bony overgrowth and other features that occur with osteoarthritis will advance our understanding. Over the last 5 years analytical methods have developed to measure a range of different biomarkers. This pilot study will use these analytical methods to measure biomarker levels in joint fluid, urine and blood of 50 participants with Osteoarthritis (OA) and 50 healthy volunteers. This study will provide novel pilot data on the changes in the composition of the synovial fluid, urine and blood in patients with OA. Apart from being a key target site for OA, the knee is a suitable joint for study because of its accessibility to clinical assessment, joint aspiration and imaging.

This is a prospective, non-randomized, consecutive series, multicenter clinical study that will include patients who will have total hip replacement with the R3 Acetabular System.

This prospective study will evaluate the Bigliani/Flatow prosthesis. The aims of this study are to establish the safety, effectiveness, and value of the prosthetic system, and to collect information from expert shoulder surgeons as to features of the implants, instruments, and techniques which may be further improved. In this study, the investigators hypothesize that this prosthetic device will significantly improve long-term patient-based outcomes, functional status and quality of life.

The purpose of this study is to demonstrate the performance and reliability of Tornier "Dual Mobility Cup" used during primary total hip replacement or hip replacement revision surgery at least 24 months post-insertion.

A better understanding of knee joint kinematics is important to explain the premature polyethylene wear failures within total knee arthroplasties (TKAs) and to help design a prosthesis that most closely approximates the normal knee. Specifically, posterior stabilizing (PS) knees have been found to be associated with lower amounts of posterior femoral rollback, higher occurrence of reverse axial rotation and increased amount of condylar lift-off. The DePuy Synthes Joint Reconstruction's Attune PS fixed bearing (FB) knee system has incorporated subtle changes in its design to address restoration of kinematics that more closely resemble those of a normal knee. To understand if this design is able to effectively restore kinematics in the implanted knee, further in vivo analysis is necessary. This pilot study will analyze 5 subjects with the Attune PS FB 3 months post-operatively using the University of Tennessee's mobile fluoroscopy unit while performing three daily activities, level walking, ramp down and deep knee bend. Since this is a pilot study, there is no hypothesis.
