Active clinical trials for "Osteoarthritis, Knee"

This is a single center randomized observational study that evaluates the cost benefit ratio between the use of two types of instrumentation in TKA: standard instrumentation vs. VISIONAIRE™ Patient Matched Technology. This study does not involve treatment or investigational products, as all components are FDA approved and are commercially available.

The goals of this study are to develop and test an educational intervention to address patients' expectations of long-term outcomes of total knee arthroplasty.

The aim of this study was to investigate the relationship between central sensitization (CS) and poor response to conventional physical therapy in patients with knee osteoarthritis (OA) by evaluating clinical parameters of pain and functionality. 84 knee OA patients with knee pain for at least 3 months and 30 healthy controls were included in the study. Socio-demographic features of the participants such as age, sex, body mass index (BMI), and duration of symptoms were recorded. Structural damage was assessed by knee radiography. Knee pain and functional status were evaluated by visual analogue scale (VAS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) at baseline and immediately after the treatment. Additionally, the following measures were applied at baseline: Central Sensitization Inventory (CSI), Beck Depression Inventory (BDI), Insomnia Severity Index (ISI), Pain Catastrophization Scale (PCS), and PainDETECT Questionnaire (PD-Q). Pressure pain threshold (PPT) was measured with a digital algometer at the painful joint, near the joint area, and in a painless remote region. Patients with knee OA underwent a total of 15 sessions of conventional physical therapy program including hotpack, ultrasound (US), transcutaneous electrical nerve stimulation (TENS), and exercise 5 days a week, for 3 weeks. The control group had no treatment except for the PPT measurement to obtain the reference PPT values. After the treatment, the patients were divided into two groups as 'responders' and 'non-responders' according to their response to treatment. The relationship between the response to physical therapy and clinical parameters was evaluated.

This study aimed to evaluate the efficacy of genicular nerve alcohol neurolysis in the treatment of pain caused by chronic knee osteoarthritis. The investigators will evaluate the efficacy of genicular nerve alcohol neurolysis using the numeric rating scale (NRS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) through patients' medical records. NRS and WOMAC scores will be evaluated before, 1, and 3 months after the procedure.

Corticosteroid and viscosupplementation injections have been used for years to treat osteoarthritic pain in knees. Recent studies have varied in reporting the effectiveness with these injections. None have been found to analyze pain scores between the groups though. This study aims to evaluate the effectiveness of corticosteroid injection (a single injection of 1 cc of 40 mg kenalog: 4 cc 0.5% Naropin) and viscosupplementation injection (Euflexxa and Synvisc, both are 2 cc of the medication given in 3 injections over a 3 week period). This will be analyzed with a modified visual analog scale over a period of time. An initial VAS will be collected prior to the first injection in the clinic. With the viscosupplementation injections, a VAS will be collected prior to injections 2 and 3 as well. These VAS are logged in the patient's chart. For both types of injections, the participant will be called and a VAS will be recorded 6 weeks post injection and 3 month post injection. These VAS will NOT be logged in the participant's chart. All VAS will be collected/recorded by the principal investigator. Statistical analysis will be conducted with a paired t-test (p<0.05 with a confidence interval at 95%) from the pre-injection VAS and VAS subsequently.

the Purpose of this study was to evaluate the short term outcome of patient specific instrument (PSI) in cases of bilateral simultaneous total knee arthroplasty (TKA) for knee osteoarthritis with sever varus

The purpose of the study is to evaluate an algorithm to screen patients with suspected knee osteoarthritis referred to an orthopedic outpatient clinic by using radiographs and patient-reported symptoms. It will be investigated whether the algorithm is able to identify which patients that are deemed relevant to undergo an orthopedic assessment. This will be evaluated by estimating the sensitivity of the new algorithm compared to with the traditional clinical assessment of the patients.

Osteoarthritis (OA) is a degenerative joint disease in which there is an imbalance between the breakdown and repair of the joint tissue. Intraarticular hyaluronic acid (HA) injections are used for the management of knee OA. Currently, there is limited and inconclusive evidence supporting use of HA injections for management of knee OA. The primary objective of our study is to evaluate the effectiveness of HA injections in the management of knee OA. Investigators will evaluate if HA injections prevent or delay knee OA surgical interventions.

Hip and knee osteoarthritis is one of the leading causes of global disability. There is no cure for the disease, but research and guidelines recommends that patients with osteoarthritis, early after the diagnosis, receive individually adapted physical exercises, information about their disease and about self-management and, if needed, recommendations on weight loss as a core treatment to prevent disability and impairment in health. This core treatment improves symptoms in osteoarthritis by reducing pain and increasing function, and have the potential to delay replacement surgery. In Sweden, core treatment has since 2008, been standardized in a supported self-management programme and evaluation and follow-ups are registered in the National Quality Register BOA (Better management of patients with OsteoArthritis). The course of deterioration in pain and physical functioning among different individuals with osteoarthritis is currently difficult to predict. Factors such as socioeconomic status and comorbidity contribute to progression of the disease, but are not fully established. There is a need for early identification of individuals who have a good prognosis with slow disease development and those that should be recommended joint replacement surgery in the future. Overriding aim of the study is to increase knowledge about the population who has received education and supervised exercises as a core treatment for hip and knee osteoarthritis and been registered in the BOA Register and to identify factors that can predict long-term outcome for this population.

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.
