Active clinical trials for "Osteoarthritis, Knee"

It was well known that total knee arthroplasty could improve the previously impaired proprioception in degenerative osteoarthritis. Most current researches have been focused on the change of the proprioception. However, the evaluation of the proprioception is based on the surrogated end. Double or single limb standing balance is considered functional scale. It is very important view for the prevention of slipping down injury in evidence-based approaches for knee osteoarthritis. Unfortunately, few study have been performed for figuring proprioceptive change after surgery out. Considering the similarity between the proprioception and the standing balance and reported positive result in proprioception after total knee arthroplasty, the investigators supposed that total knee arthroplasty might give an influence on the recovery of single limb standing balance.

The purpose of this study is to evaluate 99mTc - EC20 imaging (FolateScan), a Nuclear Medicine imaging technology that enables localization of activated macrophages in the joints of participants with knee osteoarthritis (OA). Twenty five participants with symptomatic unilateral or bilateral knee OA will undergo a one-time evaluation of the knee as follows: knee radiography, FolateScan of the knees and whole body, musculoskeletal exam, questionnaires, sampling of blood, urine and synovial fluid for analysis of inflammatory markers. Data analysis will be cross-sectional and include a comparison of the location and intensity of EC20 uptake with the following: radiographic knee OA severity, clinical measures of disease severity, cytokine expression, and synovial fluid cell count.

Retrospective collection of data, aimed at a better knowledge of the use of Synvisc® among the patients with knee osteoarthritis (OA) since at least three years.

The purpose of this study is to determine if Bone Marrow Concentrate may be successful in the treatment of osteoarthritis. Bone Marrow Concentrate is known to contain a community of cells that has been shown to have "regenerative" properties. This study is designed to evaluate the short-term clinical and x-ray outcomes of injections for hip and knee osteoarthritis. Inclusion Criteria: Subjects must be scheduled for an autologous bone marrow hip or knee injection Subjects must have a diagnosis of hip or knee osteoarthritis Subjects must be between the ages of 18 and 85 Subjects must be willing and able to sign Informed Consent Subjects must be willing and able to return for scheduled follow-up evaluations Exclusion Criteria: Subjects who have had any type of visco-supplementation in the treated joint within the last three months prior to enrollment Subjects for whom baseline data is not available

Total knee replacement (TKR) is an established treatment for knee osteoarthritis and leads to a satisfactory outcome in over 75% of patients. The pain and function after TKR can be dependent on the accuracy of initial implantation, as deviation of more than 3 degrees from the normal alignment of the limb can lead to abnormal stresses on the implant and accelerated failure. Patient specific cutting blocks may result in a more individualised implant placement, improved pain and function following surgery, and a long-lasting implant. This trial is designed to investigate if there is any benefit to bespoke instrumentation in terms of pain and function to the patient, and an economic benefit to the NHS.

Osteoarthritis (OA) is one of the most common forms of degenerative joint disease and a major cause of pain and disability affecting the aging population. It is a significant burden in terms of cost as well as the health of society and individuals. Here in our study we will try to evaluate a novel therapeutic method by using topical copper-albumin complexes cream in treatment of osteoarthritis. Then all the biochemical changes will be measured beside the evaluation of topical copper-albumin complexes cream effectiveness in relieving symptoms of the OA.

Hypothesis: The spa therapy treatment could improve health-related quality of life (HRQOL) in subjects with knee and/or hip osteoarthritis, and patients with rheumatoid arthritis. Main objective: Analyze if HRQOL in patients with knee and/or hip osteoarthritis, and patients with rheumatoid arthritis is modified by spa therapy treatment in the spa of Fitero (Spain). Design: Prospective observational study Participants: Fitero's spa users aged between 45-80 years old, diagnosed with knee and/or hip osteoarthritis, and also with rheumatoid arthritis. At least 40 patients of each type will be included in the study. Participants must be receiving a treatment of at least ten days. Main Variable: The scores obtained in the Euroqol5Dimensions-5Levels questionnaire (EQ-5D-5L) (for all subjects), the Western Ontario MacMaster Universities Osteoarthritis Index (WOMAC) questionnaire, for subjects with knee and/or hip osteoarthritis, and the Health Assessment Questionnaire (HAQ), for subjects with rheumatoid arthritis. Other variables: sociodemographic, anthropometric, clinics, and related with spa treatment. Follow-up duration: 9 months.

Type of study : Superiority study, comparative, randomized, double-blind (patient and evaluator will be blind from the randomization group), multicenter, prospective inclusion. Two groups of patients will be compared: a group of patients whose tibial sections will be performed using extramedullary mechanical sighting and a group whose tibial sections will be performed using gyroscopic and accelerometric navigation (I-Assist) will be randomized. Randomization will be performed with a 1/1 ratio per block. Population : Patients requiring 1st line total knee replacement for gonarthrosis with a Hip knee angle (HKA) between 170° and 183° who have agreed to participate in the study. Patients who have already undergone surgery on the same knee (uni-compartmental prosthesis, total knee replacement, tibial or femoral osteotomy for re-alignment, with the exception of arthroscopy) or who have vicious calls will not be included in the study. The number of subjects required was calculated using NQUERY 4.0 software for the main endpoint data, with the following assumptions: 51% of patients reaching the tibial cut target angles for the "extramedullary mechanical aiming" technique and 68% of patients reaching the tibial cut target angles for the I-Assist gyroscopic and accelerometric navigation technique. With an alpha risk of 5%, a power of 90%, and bilateral test, the number was estimated at 174 per group. Taking into account a percentage of included patients for whom total knee arthroplasty will not be performed of 10%, it is planned to include a total of 382 patients. Main judgment criteria : Achievement of the target tibial slope of 3°+/-2° and the target tibial varus/valgus at +/-2°. The tibial slope is defined by the angle (in degrees) between the mechanical axis of the tibia in profile and the tangent to the tibial cut. The varus/valgus tibial is the angle formed between the mechanical axis of the front tibia and the tangent to the tibial cut. Investigation plan : Proposal to participate in the research to any eligible patient at the time of a preoperative consultation with the orthopaedic surgeon. If the patient agrees to participate in the research (signature of the informed consent form), a randomization will be performed to determine the group of bone cutting technique. The patient will be blind to the result of randomization. The clinical follow-up of the patient will not be modified by the study, with as usual: A 6-week consultation with interrogation, clinical and radiographic examination (Face and profil x-rays, axial patella views) A 3-month consultation with interrogation, clinical and radiographic examination (Face and profil x-rays, axial patella views, telemetry of the lower limbs in charge and full profile leg x-rays). Measurements of the radiographic judgement criteria will be performed by two orthopaedic surgeons and a blind radiologist of the cutting technique used. The tibial slope will be analyzed on the entire leg radiograph in profile at 3 months. Coronal alignment will be studied on telemetry of the front lower limbs loaded at 3 months. Joint amplitudes and patient satisfaction will be assessed at 3 months postoperatively with the New IKS score, by a blind surgeon of the surgical technique used. Statistical analysis plan : Comparison of the characteristics of the 2 groups Analysis of the main endpoint: comparison of the percentage of patients with the target tibial slope achieved in both groups by Chi2 test or an accurate Fisher test, depending on the application conditions. Analysis of secondary judgment criteria by Student, Wilconxon, Chi2 or exact Fisher tests, depending on the application conditions.

Osteoarthritis is a common degenerative disorder of the articular cartilage . Risk factors include genetics, female sex, past trauma, advancing age, and obesity. The diagnosis is based on a history of joint pain worsened by movement, which can lead to disability in activities of daily living . Diagnosis of knee osteoarthritis can be confirmed based on clinical and/or radiological features. The potential of a progressive disease can be prevented or decreased by earlier recognition and correction of associated factors. Obesity and alignment especially varus malalignment are recognized factors of a progressive disease. High tibial osteotomy (HTO) is a widely performed procedure, and good results can be achieved with appropriate patient selection and precise surgical technique. It is reported to be an effective treatment for varus knee osteoarthritis (OA) by redistributing the load line within the knee joint . With an HTO, the surgeon aims to change the coronal alignment of the leg in order to shift the center of force passing axially through the knee from the arthritic region of the knee towards the unaffected side. The amount of alignment correction to be performed is calculated before surgery based on the extent of knee arthrosis and on the alignment of the patient's lower limbs on long-leg weight bearing radiographs . Our study is focused on effectiveness of open wedge High tibial osteotomy on clinical and radiographic outcomes of patients with medial knee osteoarthritis.

Pain is the dominant symptom of knee osteoarthritis and recent evidence suggests factors outside of local joint pathology, such as pain sensitization, can contribute significantly to the pain experience. It is unknown how pain sensitization influences outcomes from commonly employed interventions such as physiotherapy. The aims of this study are, firstly to identify people with knee OA who display signs and symptoms associated with pain sensitization using clinical tools and quantitative sensory testing. Secondly, we will investigate if indications of pain sensitization at baseline are associated with poor outcome following physiotherapy. Methods and analysis: This is a multi-centre prospective cohort study with 140 participants. Eligible patients with moderate/severe symptomatic knee osteoarthritis will be identified at hospital outpatient clinics. A baseline assessment will provide a comprehensive description of the somatosensory characteristics of each participant by means of clinical examination, quantitative sensory testing and validated questionnaires measuring pain and functional capacity. Participants will then undergo physiotherapy treatment, in line with current clinical guidelines. Follow-up post physiotherapy treatment (estimated to be at 3 months) will assess pain, disability (sub-scales of Western Ontario and McMasters University Score Osteoarthritis Index) and participants' global rating of change. These primary outcome measures will dichotomise participants into treatment 'responders' and 'non-responders' according to the Osteoarthritis Research Society International (OARSI) treatment responder criteria. For data analysis results from pressure pain thresholds, temporal summation and conditioned pain modulation will create a composite score of pain sensitization. Logistic regression will explore the relationship between response to physiotherapy and pain sensitization at baseline while accounting for various cofounders.
