Active clinical trials for "Osteoarthritis, Knee"

The purpose of this study is to determine whether liposomal bupivacaine is effective in the management of pain following total joint arthroplasty, as compared to standard of care analgesia.

The purpose of this study is to evaluate the immediate effects of a knee brace with a new mechanism on the pain and medial knee loading during gait among medial knee osteoarthritis patients. The effects of this new brace is compared to a stabilizing brace and a typical valgus knee brace. The investigators recruited 24 knee osteoarthritis and they have to wear each of the three braces during three months. A fifteen days wash-out period is given after each three months. Biomechanical evaluation is carried out before and after each three months. This evaluation consisted of three questionnaires (KOOS, WOMAC and Medical Outcome Score Short Form-36 (MOS-SF36)), a motion analysis with an optoelectronic system, then a 6-min walk test. During motion analysis, ten gait trials are executed without brace and ten with the brace.

The overall goal of this study is to develop regenerative cell therapy for use in patients with osteoarthritis (OA). The primary objective of this proposal is to conduct a pilot study that assesses the safety and feasibility of using concentrated bone marrow aspirate containing MSC to treat patients with painful knee OA.

We are exploring a unique weight-training program for men and women 55 years or older with knee osteoarthritis (OA) that emphasizes high-speed movements. We believe that the speed at which muscles move may be more important to the improvement of muscle performance, function and pain than how strong the muscles are. We are comparing high-speed power training with traditional strength training to determine which method has the greatest effects on muscle strength, muscle power, speed of movement, functional performance and pain. We believe that high-speed training will improve these measures to a greater extent than simply training for increased muscle strength.

Heat therapy is frequently prescribed to patients with symptomatic knee osteoarthritis (OA). Deep hyperthermia via localized microwave diathermy is effective in several musculoskeletal painful conditions. However, the efficacy of superficial heating is controversial. Furthermore, no clinical trials have yet directly compared the effects of these treatment modalities in knee OA. Hence, the purpose of the present study is to compare the effects of deep and superficial hyperthermia, induced via microwave diathermy and hot packs, respectively, on pain and function in patients with symptomatic knee OA.

Previous studies have indicated that patient expectations, beliefs and preferences may have an impact on treatment outcomes. The KIVIS study was primarily designed to compare two effective treatments for knee osteoarthritis (tidal irrigation (medical washout of the knee) or intra-articular corticosteroid injection). At study entry any preference expressed by the patient for each of the treatment interventions was recorded. This study assessed the effects of two treatments given at a single time-point and hence the effects of patient preference could be assessed independently of any compliance issues.

The purpose of the Staying Active with Arthritis (STAR) research study is to determine if a 6-month program will improve leg exercise, fitness walking, and clinical outcomes (function, blood pressure, leg strength, pain, fatigue, and health-related quality of life) in older adults with osteoarthritis of the knee and high blood pressure.

A Pilot study Randomized and Double-blinded Placebo controlled In 2 parallel group (JOINS 200mg:Placebo = 1:1) Overall 24 months treatment (JOINS:Placebo comparison up to 12 months, Additional follow-up assessment up to 24 months) Provide rescue medicine throughout whole clinical trial period.

The purpose of this study is to determine the comparative safety and efficacy of intra-articular injection of hyaluronic acid, obtained from two different sources, in the treatment of osteoarthritic pain of the knee.

Background and purpose: In the early phase after a total knee replacement (TKA), patients experience a decrease in leg muscle strength with up to about 80%. This considerable loss of muscle strength is related to reduced functional performance at this point in time. As the loss of muscle strength and functional performance is most pronounced early after TKA, rehabilitation including strength training initiated early after TKA seems a logical choice. However, tradition and fear of symptom exacerbation, such as increased knee joint swelling, knee pain and slow recovery of knee joint range of motion, have typically precluded strength training early after TKA. Hypothesis: Our hypothesis is that the effect of early rehabilitation including strength training will be greater than rehabilitation without strength training. If the hypothesis is confirmed, strength training early after TKA could be implemented directly into clinical rehabilitation practice. Participants and methods: Seventy participants with a unilateral TKA, between the age of 18 to 80 years, who understand and speak Danish, have given informed consent, will be included in this study.The study is a single-blinded randomized controlled study, where the participants receive supervised 1) rehabilitation with or 2) rehabilitation without strength training in 7 weeks. All components of the rehabilitation program (balance-, and mobility training etc.) are the same in both groups except the strength training exercises. Instead of the strength training exercises, the group without strength training spend more time on warm-up exercises, mobility- and balance exercises. The rehabilitation program lasts 1 hour per session, and will be performed twice per week. The participants perform a test battery 4 times from before to 6 months after the TKA. The test battery assesses the participants' walking ability, leg strength, knee pain, knee joint swelling- and range of motion, and self-reported function and quality of life. Ethical issues: From a pilot study conducted in the beginning of 2010, the investigators found, that strength training initiated early after TKA seems feasible, and does not increase knee joint swelling and knee pain. None of the financial supporters, or any of the authors, have any potential conflicts of interest with regard to the study.
