Active clinical trials for "Osteoarthritis, Knee"

The main purpose of this study is to evaluate the efficacy of the study drug known as duloxetine in participants with chronic osteoarthritis (OA) and knee pain in Japan.

Although total knee replacement (TKR) improves pain in numerous patients, it does not resolve many of the substantial functional limitations and physical inactivity that existed for a long time prior to the surgery. Exercise is an intervention that could improve these long-term limitations. To promote these improvements, exercise should be implemented at later stage post TKR when patients can tolerate doses of exercise sufficiently high to promote substantial changes. To date, we just don't have enough good research to tell us which type of exercise works best for which patients and under which circumstances at later stage post TKR. This research study will provide evidence for recommended interventions during the later stage post TKR. The specific research questions are: (1) How do group exercise in the community and individual exercise in rehabilitation clinic compare with usual medical care on physical function and activity outcomes? (2) Who are the patients most likely to respond to each exercise intervention? (3) Are the approaches safe?

Although few studies have showed beneficial effect of platelet rich plasma (PRP) for osteoarthritis of knee (OA knee), only one study applied randomized, control method and none of them has the objective measurements such as balance test or muscle strength which were reported as decrease in patients with OA knees. We assess the analgesic effect and the extent of improved muscle strength and balance after PRP in patients with OA knee.

Autologous adipose-derived stromal vascular fraction (SVF) was used to treat 10 osteoarthritic knees of grade II or III (K-L scale) under IRB-approved protocol in a feasibility and safety study. The adipose-derived SVF was obtained through disaggregation of lipoaspirate and resuspension of the SVF in 3 ml of Lactated Ringer's Solution, with a mean of 48 million nucleated SVF cells and a mean viability of 78%, injected per knee. Cell suspension was injected into the intra-articular space using ultrasound guidance. At 12 weeks post-op all 10 knees showed decreased pain and increased mobility, both statistically significant (α = .01). Nine of ten knees reported either maximum possible or very significant decrease in pain. No infections, acute pain flares, or other adverse events were reported. Patient ages ranged from 52 - 69 years with a mean of 59 years.

To evaluate the effectiveness of the method Proprioceptive Neuromuscular Facilitation (PNF) as physical therapy approach to the reduction of pain and improvement in functional performance and quality of life in women with knee osteoarthritis.

Assessment of the effect of spa treatment on the functional severity of arthrosis. Official title: Evolution of clinical state of patients with rheumatic disease on lower limbs or rachis, 6 months after spa treatment. Primary outcome measure: Measuring the effect of spa treatment on functional severity of arthrosis Proportion of patients with a WOMAC score augmented by 9 or more, 6 months after enrollment (minimal clinically important difference) Secondary outcome measures Quantitative evaluation of pain Comparison of mean Visual Analogue Scale (VAS) pain scale between enrollment and 6 months after Quantitative evaluation of WOMAC Comparison of mean WOMAC between enrollment and 6 months after Impact of spa treatment on the patient's metabolism Height and Weight (BMI calculation) Blood pressure Heart rate Quality of life 36-Item Short Form (SF36) at enrollment, 3 months and 6 months EuroQol 5 Dimensions (EQ5D) questionnaire at enrollment, 3 months and 6 months Opinion of doctor and patient Semi-quantitative scale collected at enrollment, 3 months and 6 months Treatment follow-up Self-evaluation of pain Self-evaluation of pain with VAS pain scale every 6 week

Physical exercise is a widely recommended treatment modality for osteoarthritis, which can be performed through a supervised group exercise or a home exercise program. However, up to now only little research has been conducted on the home exercise program in Brazil. The objective of this study is to compare the efficacy between supervised group exercise and home exercise program in people with knee osteoarthritis. Methods: The study population consists of 46 men and woman with knee osteoarthritis aged between 40 and 65. The patients should be clinically diagnosed with knee osteoarthritis and classified in Kelgreen-Laurence grades I, II and III. Primary outcomes are the Westerm Ontário and McMaster Universities (WOMAC), Lower Extremity Functional Scale (LEFS), Pain Catastrophizing Scale (PCS), Tampa Scale for Kinesiophobia, 40-meter walk test, isometric strength of hip (abduction and adduction) and knee (flexion and extension) and postural control. The patients are randomized into 2 groups, with one group receiving 12 sessions of supervised group exercise and the other group following an exercise program at home. The program lasts 6 weeks with both groups receiving the same exercise protocol consisting of stretching, isometric and isotonic exercises for major muscle groups in both lower extremities. The Mann-Whitney U test is used to examine the Anthropometric variables. The ANOVA is used to compare outcomes before and after treatment. A value of p< 0.05 is considered to be statistically signifcant.

Purpose: To evaluate embolization as a treatment for OA related knee pain versus placebo to demonstrate the actual effect of embolization on pain and disability. Participants: There will be 21 subjects enrolled over the age 40 with knee pain secondary to arthritis. Procedures (methods): This will be a single-blinded randomized-controlled study of GAE versus placebo in a small population with knee pain secondary to arthritis to determine safety and efficacy. Clinical procedures and evaluations will consist of a preoperative screening assessment to determine if the potential study subject meets the inclusion and exclusion criteria, enrollment, surgical procedure for geniculate artery embolization, and follow-up visits at 24 hours, 2 weeks, 1, 3, 6, & 12 months. An MRI may be performed after the 1-month visit.

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.

Injuries to the meniscus are common in sport. A meniscectomy is often performed to manage symptoms associated with the meniscal injury. Following a meniscectomy individuals are highly likely to develop knee osteoarthritis (OA). Footwear interventions have demonstrated biomechanical changes during walking and running, in healthy and individuals with osteoarthritis. With the increased risk of developing OA associated with meniscectomy patients, understanding biomechanical changes with footwear when compared to healthy individuals, may provide a conservative approach to delaying or minimising the development of (OA). There is no current literature assessing the effect footwear has post meniscectomy, so this is a very novel approach and can yield important results for the management of future risks. Current evidence supports the use of footwear interventions aiming to minimise OA progression in older adults during walking. Yet, meniscectomy patients who have sustained an injury during sport are likely to continue to participate in sport following treatment in their usual footwear. Further evidence is required to better understand the effect of footwear interventions during dynamic movements often performed in sport. Previous studies have assessed customised footwear interventions, however these interventions are not representative of commercially available interventions that could be widely used by the general population. Therefore assessing commercially available footwear will give a more realistic approach to conservative treatment for meniscectomy patients. This project aims to examine biomechanical differences between commercially available footwear conditions in healthy individuals and individuals who have had a meniscal injury. Three-dimensional kinetic and kinematic measures will be assessed during five tasks (walking, running, 90 degrees side cut, single leg landing, and small knee bend squat), for different footwear conditions.
