Active clinical trials for "Osteoarthritis, Knee"

This study evaluates the safety of resiniferatoxin in patients with moderate to severe knee pain due to osteoarthritis.

This study aimed to analyze the effect of platelet-rich plasma (PRP) on knee osteoarthritis. Eligible patients will undertake arthroscopic knee surgery plus intraoperative PRP and also receive second look surgery and intraoperative biopsy.

This is a study to evaluate the Clinical Performance and Safety of a single intra-articular (i.a.) injection of hyaluronic acid product (as HL-01) in the treatment of pain due to osteoarthritis (OA) of the knee.

This trial is a Phase IIa, Randomized, Double blinded, Placebo controlled, Dose finding Study to investigate the safety and efficacy of TLC599 in subjects with osteoarthritis of the knee.

The aim of this study was to assess a novel approach to treating severe knee osteoarthritis by targeting synovialmembrane, superficial articular cartilage, synovial fluid, and subchondral bone by combining intra-articular injections and intraosseous infiltrations of platelet rich plasma.This study explored a new strategy consisting of intraosseous infiltrations of platelet rich plasma into the subchondral bone in combination with the conventional intra-articular injection in order to tackle several knee joint tissues simultaneously.

Objectives: To test the feasibility of the study design and clinical effects of self-administered acupressure on relieving knee osteoarthritis (OA) pain. Hypothesis: self-administered acupressure would have a superior beneficial effect compared to health education control group in terms of pain relief in patients with knee osteoarthritis across the 6-week study period. Design and subjects: A pilot randomized controlled trial. 36 subjects with knee OA will be recruited; 18 per group. All eligible subjects will be randomized to either self-administered acupressure or health education control group in 1:1 ratio. Interventions: Subjects in the self-acupressure group will attend two 1.5 hours training sessions to learn self-acupressure and will practice self-acupressure every morning and night for 6 weeks; subjects in the education control group will receive two 1.5 hours training sessions to learn the health information related to knee OA. Main outcome measures: The primary outcome measure is the numerical rating scale for knee pain. Other measures include Western Ontario and McMaster University Osteoarthritis Index, knees' range of motion (ROM), and SF-6D. Acceptability of the self-acupressure training course will also be evaluated. Data Analysis: Differences in the questionnaire scores and ROM will be examined using a mixed-effects model. Both completer and intention-to-treat analyses will be conducted. Effect sizes will be computed by dividing the difference in means by the pooled standard deviation.

Osteoarthritis of the knee (KOA) is the most common cause of disability in older adults. Osteoarthritis involves a loss of cartilage, which acts like a cushion between the bones as well as changes in the bones of joints. Once the joint cartilage is gone, the body does not produce new cartilage. Joint damage can contribute to pain. Currently, treatment for pain associated with knee osteoarthritis includes exercise. However, exercise at a medium- to high-intensity level can be problematic for people with knee pain. Because exercise is a common treatment for knee pain but many people experience pain during exercise, researchers hope to find a safer and more effective exercise method to strengthen the muscles around the knee. Both aerobic exercise and resistance exercise are recommended for the treatment of people with knee pain. However, pain can be a barrier to participating in exercise at a moderate or vigorous intensity. Electrical stimulation of muscles holds potential to allow effective exercise to be completed at tolerable intensities. Transcutaneous electrical nerve stimulation (TENS) is the use of very low electric currents produced by a device to stimulate the nerves, to treat pain. Neuromuscular electrical stimulation (NMES) uses low electrical current to cause muscles to contract. By doing this study, the investigators hope to learn if a hybrid training system (HTS), using a combination of NMES and walking, is effective in strengthening muscles in people with knee pain, aching or stiffness. In this pilot study, the investigators will use walking with TENS as conventional exercise. Randomized controlled trial will be conducted to compare the effect of walking augmented by HTS with walking without HTS. The investigators will evaluate the relative advantages of training that combines HTS with conventional walking exercise on the improvement of muscle strength, physical function, and pain relief in obese women with frequent knee symptoms. Study Hypotheses: Compared with walking with sensory TENS, walking with HTS will: 1 increase quadriceps muscle strength. 2 decrease knee pain. Exploratory Hypotheses: 3 improve physical function. 4 increase PPT (improve central sensitization). 5 improve self-reported quality of life.

This phase III clinical study will be conducted in Brazilian research sites. It will be included in the study 314 participants diagnosed with primary knee OA according to the classification criteria of the ACR. After a washout period, the participants will be randomized to receive the combination of glucosamine sulfate + chondroitin sulfate of bovine origin of Eurofarma Laboratorios S.A. (N= 157) or the combination of glucosamine sulfate + chondroitin sulfate of Zodiac Pharmaceuticals S.A. Condroflex ® (N = 157). The treatment period of the study will be of 24 weeks. Each participant will perform seven visits to the research site. The main evaluations will be the improve of pain in the target knee by questionnaire Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and quality of life by SF-12 questionnaire.

The purpose of this study is to verify the effect of cryotherapy in pain control, function and quality of life in individuals with knee osteoarthritis.

Whole body vibration (WBV) acutely improves quadriceps strength, and may improve long-term outcomes in individuals with anterior cruciate ligament reconstruction (ACLR). However, it is unclear if WBV influences athletic tasks such as running. The purpose of this study is to evaluate the influence of WBV on running biomechanics in individuals with ACLR.
