Filter by:Randomized study comparing surgical and economic parameter of Total Knee Arthroplasty performed using two different specific surgical techniques.
The purpose of this study is to determine the feasibility and preliminary efficacy of two weeks of self Transcranial Direct Current Stimulation (tDCS) for pain in older patients with knee osteoarthritis (OA).
This study is a randomized controlled clinical trial using a blind evaluator. Fifty-one volunteers were selected from 50 years to 70 years, obeying the following criteria: diagnosis of knee OA grade II and III through the radiographic classification of Kellgreen and Lawrence 1955, Body mass index (BMI) less than 40 kg / m², volunteers should have had knee pain for at least six months. All are from the Rehabilitation Sector of Santa Casa de Misericórdia de São Paulo (ISCMSP). The subjects were evaluated through a questionnaire developed by the authors of the study (Annex I), the Visual Analogue Scale (EVA) (Annex II), then applied to the Lower Extremity Functional Scale LEFS (Appendix III) and the Activities of daily living scale ADLs (Annex IV). In addition, the evaluation of muscular strength was through dynamometry using the Lafayete dynamometer model 01163, which was performed by a blind evaluator regarding the group that will belong to each candidate. The muscles tested were: quadriceps, ischiostibial and gluteus maximus. The randomization was through 60 brown envelopes divided into A, B, C and D, designating the randomness of the sample. In addition to the initial evaluation, an evaluation was performed at the end of the tenth session and after 3 months of treatment. The volunteers underwent a five-week treatment program, totaling 10 sessions, divided into four groups, group A - Intervention (INT) underwent knee and hip muscle strengthening exercises and electromagnetic field therapy with (Meditea - ARG) using the coplanar technique, group B - Exercises (EXE) carried out exercises to strengthen the hip and knee muscles in the C - Placebo group (PLA). hip and knee and electromagnetic field therapy with the Magnetron® coplanar technique, but with the device switched off and group D - Apparatus (APA) only use electromagnetic field therapy with the magnetron® coplanar technique. In the present study, there were no significant differences between groups regarding pain, function and muscle strength. However, group A obtained better results in the evaluated criteria, tending that the combination PEMF and exercises, is an indicated treatment for OA knee.
Pilot, open non-controlled trial to assess the feasibility of implementing objective parameters as primary endpoints in a clinical trial with patients affected by knee osteoarthritis.
High Tibial Osteotomy (HTO) is an alternative to knee replacement in suitable patients with early knee osteoarthritis (OA), it is particularly suited to patients with single compart disease who otherwise would be suitable for unicompartmental knee replacement (UKR). OA of the knee is very common and increasing driven by the ageing of the population. The current limitations of HTO are related to the difficulty of achieving the desired correction due to a challenging surgical technique and soft tissue irritation due to the use of generic stabilisation plates. This study will examine the safety equivalence of a new patient specific HTO process which has patient specific 3D printed plates, i.e. personalised HTO plates, with the existing most commonly used HTO procedure using the Tomofix generic HTO plate. Importantly this study will be undertaken as a Virtual Trial, existing anonymised 3D imaging data will be used to create the virtual patient cohort. This cohort will receive both procedures, which for this type of procedure is only possible in a virtual scenario. The main question to be addressed is: "Is the personalised HTO procedure as safe as the most commonly used existing generic HTO procedure?". In this context safety concerns the mechanical loads placed upon the tibia and the support plate. The interventions will all be made on computer models, the 3D imaging data will be used to create the intact (un-operated) models of the subject tibias. Each model will then be virtually operated upon, with both the personalised and generic HTO procedures. The models will then be loaded with physiological loads experienced during function and the mechanical states compared.
To determine if the use of patient-specific custom cutting blocks for implantation of total knee components results in improved limb alignment and component positioning compared to regular instrumentation.
This study will examine the effect of exercise on the turnover of collagen in articular cartilage and the content of cytokines in the synovial fluid from human adults with osteoarthritis.
The investigators believe that amniotic tissue allografts may be an effective modality to treat osteoarthritis (OA) of the knee. One important mechanism of action may be stimulation of the synovial cells to increase production of endogenous hyaluronic acid (HA). A second mechanism may be the increase in the anabolic factors and a decrease in degenerative factors in the joint. The Investigators propose to quantify the concentration of HA and selected anabolic and degradative factors in synovial fluid aspirate pre and post implantation. While the treatment provided is designed to provide pain relief for symptoms, the purpose of this study is to learn more information about the impact of amniotic tissue allografts on inflammatory markers and growth factors in the knee joint.
Osteoarthritis (OA) is the leading cause of disability worldwide and affects more than 4.4 million people in Canada (13% of Canadians). OA symptoms include joint pain, stiffness, range of motion loss, and inflammation, resulting in a significant decrease in quality of life. Current evidence-based guidelines for OA management recommend weight loss, patient education, exercise therapy, bracing, viscosupplementation, and anti-inflammatory/pain medications prior to joint replacement surgery. Unfortunately, current practice trends are not consistent with these guidelines and focus largely on joint replacement. Recently, research from a group in Denmark has shown a reduction in the progression of knee OA symptoms, joint related painkiller use, individuals on sick leave, and higher physical activity levels 12 months after a combined patient education and standardized group exercise therapy program (GLA:D®). Based on the Danish success, the GLA:D® program has been made available in Canada. To date it is unclear if the GLA:DTM Canada program will result in outcomes similar to those seen in Denmark, or how the GLA:DTM program compares to existing individualized OA care programs (i.e. JointEffort). This research will answer the following three questions; 1. Is the GLA:DTM standardized education and exercise program associated with improvements in functional mobility, quality of life, pain management, and inflammatory biomarkers in knee OA patients in Calgary, Alberta? 2. Is the JointEffort individualized exercise and education program associated with improved functional mobility, quality of life, pain management, and inflammatory biomarkers in knee OA patients in Calgary, Alberta? 3. Do the improvements in functional mobility, quality of life, pain management, and inflammatory biomarkers in knee OA patients differ between those enrolled in the GLA:DTM and the JointEffort education and exercise programs?
Patients who received a total knee endoprosthesis BPK-S Integration between 2011 and 2013 will be invited to participate in this PMCF study provided sufficient source data documentation is available regarding preoperative, intraoperative and early postoperative follow-up assessments. Only patients providing written informed consent prior to any study data collection can take part in the study. Preoperative, intraoperative and early postoperative data (3 months, 1 year and 2 years after implantation) will be collected retrospectively. Additional long-term follow-up of one visit (year 7 after implantation) will be documented prospectively. Only parameters assessed in clinical standard care for follow-up (implant control) visits will be collected for this PMCF study. Radiological assessment of the implanted prosthesis will only be conducted if medically indicated according to the investigator. No additional study related assessment will be performed. Only anonymized data will be used in this observational study to protect patient privacy. No personally identifiable information will be collected.
