Active clinical trials for "Osteoarthritis, Knee"

This is a prospective, multicenter, observational study with a planned follow-up period of 10 years to confirm the safety and performance of the GEMINI SL Fixed Bearing PS knee prosthesis in longterm follow-up under routine conditions. Primary outcome of the study is the 10-year survival rate of the GEMINI SL Fixed Bearing PS knee prosthesis with revision for any reason as the endpoint.

Osteoarthritis (OA) is the main cause of pain and disability in elderly. For knee OA, a total knee replacement (TKR) is an effective surgical treatment, and the majority of patients report substantial pain relief and functional improvement following surgery. However, 20-40% of patients undergoing TKR are dissatisfied with postsurgical outcome. Even after revision, some patients keep complaining of persisting pain. In this study, the investigators will examine putative prognostic factors on the basis of the biopsychosocial model. Besides several psychological factors (measured with questionnaires), the investigators will assess structural impairments (such as radiographic severity of OA), functional impairments (muscle weakness and proprioceptive deficits), anesthetic procedures, immediate postoperative pain management, metabolic factors (body composition and hemoglobin A1c), inflammatory factors (C-Reactive Protein) and the investigators also will examine the role of altered central pain processing (CPP) (primary and secondary mechanical hyperalgesia, mechanical temporal summation, thermal primary and secondary hyperalgesia, endogenous pain modulation). With a longitudinal study design, this study will explore which factors are predictive of poor outcome in knee OA patients after TKR. Moreover, the interrelationship between CPP, structural, functional, metabolic, inflammatory and psychological factors, and the clinical expression of knee OA (pain, symptoms, physical performance and quality of life) will be investigated. Further research on the role of the aforementioned putative prognostic factors on postsurgical outcome could contribute to better management of these patients, since these factors may be particularly important for patient-tailored treatment.

Evaluation of a new navigation system in computer-assisted total knee arthroplasty.

Objective: Identifying the dose of EVI-01 with the best clinical response, balancing the efficacy, safety, and tolerability of the investigational product. Study design: Interventional, dose-finding, three arms, randomized (1:1:1), parallel assignment, double-blind, controlled by an active comparator.

Osteoarthritis (OA) is a chronic degenerative joint disease characterized macroscopically by progressive damage of articular cartilage, joint space narrowing, subchondral bone remodelling, joint marginal osteophyte formation and synovitis. It is also characterized by a decrease of the concentration and molecular weight of the hyaluronic acid in the synovial fluid which ultimately leads to poor viscoelastic properties of synovial fluid and induction of proinflammatory pathways. The intra-articular injection of viscosupplementation gel (mainly exogenous hyaluronic acid) represents one of the most used therapeutic strategies to treat osteoarthritis symptoms. Several studies on knee Osteoarthritis, have shown that one or more weekly injection of viscosupplementation gel significantly relieves articular pain and ameliorates mobility and joint function for at least 6 months and more. Repeated courses of intra-articular injections are an effective and safe treatment for knee osteoarthritis symptoms. Based on studies conducted on intra-articular viscosupplementation gels, the most common side effects expected are local transient and short-lived adverse events such as pain, swelling and arthralgia in the site of administration, which are fully reversible in the days following the injection. Furthermore, such local effects may occur in a minority of cases and are usually treated conservatively with ice, non-steroidal anti-inflammatory drugs, and relative rest.

By recruiting knee osteoarthritis patients and treating them with melatonin, this study aims to determine the efficacy and safety of melatonin in alleviating pain in this patient population.

It is known that the global socioeconomic burden of individuals with knee osteoarthritis (OA) is on a constantly rising curve. In addition, it is predicted that this burden will increase with the increase in the aging rate of countries. While the evidence level of exercise in the treatment of individuals with knee OA is at A level, a standard exercise program has still not been established for these individuals. One of the most important elements in establishing a standard exercise protocol can be realized by understanding how exercise provides positive effects in these individuals. Today, the gold standard practice used in examining the effectiveness of treatments such as exercise is the follow-up of biomarkers. However, for this purpose, biological fluids (blood, urine, synovial fluid) samples are not taken from individuals with knee OA during routine health controls. Existing laboratory detection methods, especially ELISA analysis, are very detailed, time-consuming and expensive, among the reasons why they cannot be included in routine clinical practice. This situation makes it difficult to examine which biomarkers the exercise programs applied in individuals with knee OA have an effect on and to establish a standard exercise protocol. Therefore, the number of randomized controlled studies examining this issue is very few in the literature, and this number is much less in Turkey. The researchers aimed to create a standard home-based exercise program by examining the effects of the holistic exercise approach for all lower extremity muscles, which the researchers created considering the EMG studies in the literature for individuals with knee OA and the age group to be included in the study, both at the physical (pain, functional status, quality of life) and biochemical level (inflammatory biomarkers that have not been examined together before and whose relationship with OA has been newly discovered).

The purpose of this study would be to investigate: The effect of using percussion massage gun on Hamstring flexibility in patients with knee osteoarthritis. The effect of using percussion massage gun on pain in patients with knee osteoarthritis. The effect of using percussion massage gun on ROM in patients with knee osteoarthritis. The effect of using percussion massage gun on knee function in patients with knee osteoarthritis.

The aim of this study is to determine the effectiveness of the program integrated with pain science education for people with painful knee osteoarthritis (OA). Another purpose of the study is to evaluate whether the program integrated with pain science education is more effective than the program integrated with biomedical education.

The goal of this observational study is to gain insight in the natural course of pro-inflammatory factors and hemarthrosis in patients older than 18 with a recent knee trauma. The main question[s] it aims to answer are: What is the natural course of pro-inflammatory factors and hemarthrosis in knee trauma? What are the effects of inflammation and hemarthrosis on the anti-inflammatory potential of ASC's in order to better determine eligible patients and circumstances for ASC's therapy? Participants will: undergo blood withdrawal undergo knee arthrocentesis for synovial fluid sample collection physical examination fill out a questionnaire on knee complaints
