Active clinical trials for "Osteoarthritis"

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.

This is a methodological study designed to investigate a new model for testing pain agents in the treatment of patients with osteoarthritis (OA). This will be a double-blind, randomised, placebo controlled three-way cross-over study in patients with OA of the knee.

Objective: To assess the impact of intraarticular hyaluronic acid (HA) on clinical outcome and on volumetric and T2 relaxation based changes of articular cartilage in mild to moderate osteoarthritis (OA) of the knee joint. Methods: Patients with moderate OA of the knee [Kellgren-Lawrence II] were recruited for a 6-months prospective, randomized clinical trial evaluating the effect of HA on articular cartilage morphology and composition. Clinical examinations and MRI were performed at baseline, and after 6, 12 and 24 weeks. Cartilage volume, thickness and surface area were determined in cartilage plates and subregions were defined using proprietary software. MRI was performed on a 1.5 Tesla scanner; morphological evaluation was performed using 3D T1-w FLASH Waterexcitation (WE) sequences and T2 maps were calculated from a multiecho, spin-echo sequence.

Medial compartment osteoarthritis of the knee is commonly treated by a surgical intervention called 'high tibial osteotomy' (VTO). Although it has repeatedly been shown that pain improves following this procedure, it is unknown how cartilage quality is affected by the procedure. In this study, a recently developed MRI technique is used to evaluate changes in cartilage quality before and after the surgery. Changes in MRI signals are correlated to subjective improvements (score lists). 10 patients participate in this study. Approval has been granted by the Medical Ethical Committee of the University Medical Center Utrecht. All participants are required to give informed consent before participation.

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.

The purpose of this study is to develop a conjoint analysis-based questionnaire and decision aid for patients with osteoarthritis of the knee and to compare the responses of two groups of subjects, one receiving only printed information about knee osteoarthritis, the other participating in a computer-based adaptive conjoint analysis program.

The study hypothesis is that the relief of pain in patients with osteoarthritis in the hand can be detected by a form of brain scanning that detects which parts of the brain are activated when pain is felt.

The goal of this study was to clinically validate a new device for the objective outcome evaluation of adult patients undergoing shoulder surgery for glenohumeral osteoarthritis and rotator cuff disease, using the activities of daily living described in the Simple Shoulder Test (SST) as a reference. The study was set up as a clinical trial including patients over an observation period of one year and a control group of subjects. Clinical evaluations will be made at baseline, 3 months, 6 months and 1 year after surgery by two independent observers. Miniature sensors each containing three 3D gyroscopes and three 3D accelerometers will allow computing new kinematic scores. They will be compared to the regular SST, DASH, ASES and Constant scores.

The purpose of this study is to look at the outcomes of the GENESIS II Posterior Stabilized Total Knee Replacement.
