Active clinical trials for "Osteoarthritis, Knee"

Osteoarthritis (OA) is a progressive disease characterized by degeneration of the joint cartilage, which is involved in the immune system leading to proinflammatory cytokine and metalloproteinase release. Knee osteoarthritis is the most common form. The healing is very slow and the damage is not fully recovered, so the degeneration process continues and no treatment modalities completely remove this process. Various methods are used in the treatment of OA and total joint replacement is performed in the patients with OA recently. Ten patients with Kellgren-Lawrence grade II-III knee OA who had been applied for knee pain and received conservative treatment for 6 months and had no benefit will be taken to study. Patients will be assessed 7 (V1-7) times during the study. Clinical, immunologic and radiological treatment effectiveness and clinical improvement will be evaluated at the beginning of the treatment and in all follow-up patients participating in the study.

Health care professionals are dedicated to the ongoing evaluation of the peri-operative experience, and always striving to improve patient satisfaction. There are extensive protocols and communication strategies to optimize pre-operative education, intra-operative comfort and safety, and post-operative pain control, but most strategies are carried out by the treating team. The idea of using mindfulness to empower patients to be active participants in reducing pain and anxiety has already been successful in a number of medical settings. Multiple studies have demonstrated the effectiveness of mindfulness based stress reduction and mindfulness based cognitive therapy, a modification to treat depression. Mindfulness has been shown to reduce catastrophizing, depression and disability, all of which are of concern with respect to long-term success after arthroplasty. There is limited evidence to demonstrate the usefulness of mindfulness as a peri-operative intervention. Although there is evidence that a brief mindfulness meditation session can impact experimental pain scores and anxiety, there is no current literature that has evaluated the impact of such a session as part of the peri-operative teaching protocol with respect to pain and anxiety. Our objective is to assess the capability of a short-term mindfulness intervention (serving as a compliment to the pre-operative pathway for total joint arthroplasty) to reduce peri-operative pain that can be integrated with the existing arthroplasty pathway. In addition, we explore the utility of using such a tool to reframe patients' expectation of the peri-operative period as evidence by its impact on anxiety and post-operative patient satisfaction. Thirty-two participants will be recruited and randomly assigned to either control or treatment groups. The control group will receive standard care associated with total joint arthroplasty. The treatment group will receive a 45-60 minute mindfulness meditation teaching session administered by a credentialed mindfulness instructor and affiliated with the University of Calgary Psychosocial Oncology Mindfulness Program in addition to standard care for arthroplasty surgery. The treatment group will be assigned "homework" recordings of body scan exercises and asked to listen to the recording daily for the two-week period prior to surgery. Patients will be asked to listen to their body scan meditation immediately prior to entering the operating room and daily each post-operative day while in hospital. Longitudinal assessments encompassing the preoperative, peri-operative and post-operative periods will be acquired using validated pain scores and anxiety outcomes scores including the Numerical Rating Scale (NRS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the short-form State-Trait Anxiety Inventory.

As demand for knee joint arthroplasties surge, improving long term patients' satisfaction and implant survivorship has become of utmost importance, as patients seek not only to alleviate their condition, but also return to their usual daily activities and sports. Implant type and design plays an important role in this, with many modern designs seeking to replicate the native knee's kinematics and alignment through mimicry of native knee biomechanics in its femoral components, tibial components, and polyethylene bearing inserts. The Zimmer-Biomet Persona® Total Knee Cruciate-Retaining Femoral Component (CR Femur), used in conjunction with the kinematic alignment surgical technique, has been shown to produce better functional outcomes and improved patient satisfaction following total knee arthroplasty. More recently, Zimmer-Biomet introduced the Medial Congruent Bearing (MC Bearing) design to be used with the CR Femur; the design facilitates greater stability through increased anterior lip height compared to the original Cruciate Retaining Bearing (CR Bearing), thus allowing for greater anterior constraint and subluxation resistance that aids in activities requiring deeper flexion or full extension. However, the evidence that this will lead to better patient satisfaction and function is scarce, and requires further study to prove that the MC Bearing is a better insert choice to recommend to both surgeons and patients alike. 120 patients from Singapore General Hospital seeking primary total knee replacement surgery will be recruited for this study, and randomised in a 1:1 ratio to receive either the CR Bearing or the MC Bearing alongside the Zimmer-Biomet CR Femur implant. They will be followed up for two years post-operatively, and their outcomes recorded at specific milestones to be analysed for the impact of insert design on knee function, patient satisfaction and quality of life post-surgery.

Mesenchymal stem cells (MSC) are stromal cells that have the ability to self-renew and also exhibit multilineage differentiation. MSCs can be isolated from a variety of tissues, such as umbilical cord, bone marrow, and adipose tissue. The multipotent properties of MSCs make them a promising option for the treatment of osteoarthritis (OA). Bone marrow mesenchymal stem cells (BM-MSC) and adipose derived mesenchymal stem cells (AD-MSC) have been used separately to treat OA. The aim of the present study will be to compare in a randomized non blind controlled clinical trial 3 types of intra-articular injections containing MSC populations obtained from two clinically relevant sources: BM-MSC, AD-MSC and a combination of both BM-MSC and AD-MSC.

Radiofrequency ablation of the genicular nerves using ultrasound is safe and effective for treating intractable knee osteoarthritis pain by using either monopolar or bipolar radiofrequency ablation. This technique is based on anatomical studies demonstrating that genicular nerves are accompanied by genicular arteries. Ultrasound-guided RF genicular ablation yielded both significant reductions in knee pain and improvements in functional capacity.

The aim of this study is to compare the efficacy of transcutaneous electrical nerve stimulation (TENS), interferential currents (IFCs) and sham devices in improving central sensitization (CS) findings, including pressure pain thresholds, pain catastrophizing, depression, and kinesiophobia in patients with knee osteoarthritis (OA).

This is a randomized controlled trial comparing the short-term and medium-term effect of self-administered and knee health education for relieving knee pain in middle-aged and older adults with knee osteoarthritis.

The purpose of this study is to evaluate the effect of TENS at the knee pain.

Osteoarthritis (OA) of the knees is the most common degenerative disorder seen in a rehabilitation outpatient clinic. It is characterized by structural changes in the articular cartilage and the surrounding tissues. The understanding of its pathophysiology is still unclear. Knee OA patients are often troubled with knee pain and functional disturbance. Several studies have shown that the earlier the injection of autologous platelet rich plasma (PRP) to treat early stages of knee OA, the better the treatment outcome. However, there are controversies as to whether PRP injections can also be effective in treating patients with moderate to severe degrees of knee OA. Synovial fluid (SF) is in contact with the primary tissues affected by OA (cartilage and synovium). Identifying the SF biomarkers can provide us with crucial information in monitoring the PRP treatment response. PRP is blood plasma that is rich in autologous platelets. Platelet releases growth factors and cytokines that can stimulate the healing of soft tissue structures. However, the amount of platelets in human blood is not concentrated. Purification and centrifugation procedures are needed to concentrate these platelets. The human knee cartilage is contained inside the knee joint and has scarce blood supply. When the cartilage is injured, growth factors can hardly reach this area to repair the cartilage. Therefore, many studies have suggested early usage of PRP in treating knee OA. Some studies have stated that the effect of PRP in treating knee OA is superior to that of hyaluronic acid (HA). Recent studies have recommended the application of high frequency PRP injections (ex/ intra-articular (IA) PRP injections on a weekly basis) in treating patients with more severe degrees of knee OA. Prolotherapy using hyperosmolar dextrose solution has been shown to have some positive effectiveness in treating patients with knee OA. Higher percentage, such as > 12.5% of dextrose water, may stimulate cartilage repair. Lower percentage, such as 5% dextrose water, has been documented to play an essential role in anti-inflammation, and pain reduction.

This study is designed to determine the effect of a cycling training program which modulates frontal and sagittal plane knee joint loading with graded increases of Q-Factor and cycling workrate in persons with symptomatic knee osteoarthritis.
