Active clinical trials for "Osteoarthritis"

This long-term outcomes study is designed to collect safety and efficacy data on designated, commercially available, hip arthroplasty products.

The purpose of this study is to determine if patients with chronic painful knee osteoarthritis experience meaningful and long-term improvement in pain, function, and analgesic use after ultrasound-guided pulsed radiofrequency of the genicular nerves following a double diagnostic genicular nerve blocks.

The primary aim of the study is to investigate the effects of supervised exercise therapy and education on the immediate response to using a soft knee brace in patients with knee osteoarthritis (OA).

This study examines carpometacarpal osteoarthritis (CMC OA) and aims to elucidate the biomechanical, neuromuscular, and somatosensory mechanisms that contribute to CMC OA symptoms by using orthopaedic biomechanics and quantitative pain testing. Completion of this study will provide a comprehensive dataset describing how movement strategies (muscle activity and joint posture) as well as experimental and clinical pain differ between individuals with CMC OA and age-matched controls.

Osteoarthritis (OA) knee is chronic, slowly progressive, degenerative disease of joint which affects articular cartilage and accompanied by pain, swelling and loss of function . OA is often considered as the serious joint disease as it has negative impact on quality of life among elderly population, it is the major cause for the reduced mobility. At cental level, due to imbalance in endogenous pain modulation there is reduce capacity of brain to inhibit the pain. Therefore, dysregulation in the central modulation of pain further leads to maladaptive changes in the brain structure. Transcranial direct current stimulation is a non-invasive method to modulate the brain structure by using a week direct current applied through the scalp in painless way. Multi-session for prolonged time can induce neuroplastic changes in the brain. The aim of the study is to demonstrate the effectiveness of tDCS in reducing the pain among patients with chronic knee OA and to modulate the plastic changes in brain structure. A total of 80 patients with KOA will be recruited by the convenience sampling to participate in this two group pretest-posttest, double blinded randomized clinical study. After the demographics, recruited 80 patients with KOA will be randomly divided into two groups, transcranial direct current stimulation (tDCS) group and conventional physiotherapy (CPT) group with by block randomization. Patients with KOA in tDCS group will be provided with Active tDCS and conventional physiotherapy and CPT group will receive structured exercises protocol. Pre-post changes in the outcome measures will be documented at baseline and end of 8-week post intervention. Each session will last for approximately 30 minutes duration.

A prospective, multi-centre, non-comparative, post-market clinical follow-up study to evaluate the survivorship, safety and performance of the Freedom® Total Knee System in the treatment of approximately 450 subjects who in the surgeon's opinion require a primary total knee replacement due to severe knee joint pain and loss of mobility due to osteoarthritis, rheumatoid arthritis or post-traumatic arthritis at upto 15 centers in the United Kingdom (UK). The primary objective of this study is to obtain implant survivorship and clinical outcomes data for commercially available Freedom® Total Knee System used in total knee replacement. Subjects must meet all the study inclusion / exclusion criteria before enrolment in the study. Subjects will be requested to attend out-patients clinic for clinical follow-up (CFU) or approached for telephonic follow-up (TFU) post-operatively as mentioned below. Clinical & Telephonic Follow-up details: 6-8 weeks ± 1week (Clinical follow-up) 1 year ± 1 month (Clinical follow-up) 3 years ± 6 months (Clinical follow-up) 5 years ± 6 month (Clinical follow-up (optional) / Telephonic follow-up) 10 years± 6 month (Clinical follow-up (optional) / Telephonic follow-up)

Total hip and knee replacements (TJR) for osteoarthritis are common orthopaedic procedures performed in Canada. Waits for these procedures are already common and lengthy, and the COVID-19 pandemic has resulted in the further of delay of thousands of scheduled TJRs. Longer wait times for TJR can be associated with increased pain and functional disability, and up to 80% of patients awaiting TJR use opioids for pain management. Further, pre-operative pain, functional disability and opioid use has been linked to worse recovery and continued opioid abuse post-operatively. Interestingly, some clinical studies have shown that not all patients experience a deterioration in symptoms while on the waitlist for TJR, and a longer wait time is not always associated with poor post-operative outcomes. However, there is insufficient evidence surrounding the relationships between wait time, patient characteristics, and outcomes both prior to and following hip or knee replacement. The Investigators aim to establish a large prospective cohort of patients with osteoarthritis waiting for TJR with key research questions and the overarching objectives of identifying which patients deteriorate while on the waitlist, and how wait time affects patient-important outcomes following surgery. The study will enroll 3008 patients awaiting TJR at 10 Centres from across Canada. All participating site investigators are fellowship trained Orthopaedic surgeons, working in acute care facilities with active research programs and dedicated research staff. The study will follow the patients from their waitlist enrolment up to two years post-operatively. During this time, the research team will collect pain, function, opioid use, and quality of life measures at regular intervals. In addition, an economic analysis will be conducted to determine the impact of length of time on a waitlist on patient and healthcare system costs. The data will highlight the consequences of long waits for patients undergoing TJR, information that will improve patient care and provide insight for refining wait list policies.

Prospective Multi-Center Registry on study subjects with implanted devices marketed and legally commercialized in the USA by FX Shoulder Solutions.

This study investigates the safety and combined effect of Turmeric, Black Seeds, Flaxseed, and Medicago Sativa for relieving symptoms of knee osteoarthritis compared to the placebo group.

The biological study involves the collection of samples from male and female patients (intraoperative waste tissue, blood and synovial fluid), suffering from mild and moderate-severe OA, who undergo endo or arthro-prosthesis surgery, or arthroplasty, for the identification and characterization of a panel of "gender-specific" miRNAs. MicroRNAs will be extracted from the samples (chondrocytes, synoviocytes, osteoblasts and plasma) and will be molecularly characterized in order to identify a panel of miRNAs differently expressed according to the gender and severity of OA. The lymphocyte and phenotypically and functionally characterized populations will be isolated from the corpuscular component and the synovial fluid, in order to evaluate a possible gender-specific difference in the progression of OA-dependent inflammation.
