Active clinical trials for "Osteoarthritis, Knee"

The purpose of this study is to elucidate whether patients operated with THA and TKA can benefit from treatment with chlorzoxazone.

Primary Objective: To assess the safety and tolerability of ascending single intraarticular doses of GZ389988 in patients with painful osteoarthritis (OA) of the knee. Secondary Objectives: To assess the pharmacokinetic (PK) parameters of ascending single intraarticular doses of GZ389988 in patients with painful OA of the knee. To obtain preliminary pharmacodynamic evaluation of ascending single intraarticular doses of GZ389988 in patients with painful OA of the knee.

In this project, investigators aim to investigate the effects of action observation therapy on pain, fear of movement, functional level and brain hemodynamics in patients with knee osteoarthritis. The study is unique in that this method, which has already been used for post-surgical or motor healing, aims at long-term administration for the first time with chronic pain and objective visualization of the results. This study will create a new perspective to understand the physiology of pain, which has attracted much interest in the literature in recent years, and will shed light on the studies that can be done in this regard. Participants' joint range of motion in the initial assessments will be measured by electro-goniometer, muscle strength assessment by JTech hand dynamometer at appropriate evaluation positions. In assessing pain, pain levels at rest and during activity will be questioned using Visual Analog Scale. Fear of movement of individuals will be assessed via Tampa Kinesiophobia Scale and functional levels will be assessed via Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Timed Up and Go Test. Functional near infrared spectroscopy (fNIRS) will be used for evaluation of brain hemodynamics. The first group, will receive exercises with action observation therapy; and the second group will receive only exercises. The exercise programme will be administered under physiotherapist supervision for three days a week for six weeks. The evaluations will be repeated at the beginning of the study and at the end of the sixth week. Data obtained from the study will be analyzed using appropriate statistical methods.

This study evaluates postoperative numerical pain score and systemic opioid requirement within 48 hours for unilateral total knee arthroplasty. Comparing among 3 groups of intrathecal morphine; 0,50, 100 ug with multimodal analgesia.

Total knee replacement (TKR) is the treatment of choice for patients suffering from long standing severe pain, functional limitation and instability caused by osteoarthritis (OA) of the knee joint's surfaces. Long standing arthritic joint surfaces, more often lead to pain and swelling and other physical factors that may contribute to knee joint instability. This instability causes a feeling of 'unsteadiness' whilst walking and may also contribute to falls. In view of the latter, it is important for this issue of 'unsteadiness' to be addressed. TKR helps to remove the cause of pain and swelling, but exercises are crucial to counteract the joint' instability and any feeling of 'unsteadiness' before and after surgery. However, research hasn't yet identified the optimum approach for delivering exercises that will help in patients' rehabilitation. Current studies have tried to incorporate rehabilitation programmes to improve this issue, but required a delivery of 6-8 weeks of exercises which has resulted in a logistical burden in view of the long duration. We have scientifically developed a new programme of exercise for the muscles of the knee that can be delivered during a single week prior to surgery. The pre-surgery exercise-programme (P-SEC), potentially offers similar effectiveness for improving the feeling of 'unsteadiness' and muscle' fitness as programmes that last much longer. Therefore, the purpose of this research study is to test the effectiveness of this new, short approach to exercising in patients who are waiting for a TKR surgery.

The aim of this study is to improve the referral rates to physiotherapy of patients with knee osteoarthritis. The intervention consists of one academic detailing visit directed to general practitioners (GPs)

Osteoarthritis of the knee is a very prevalent disease. However, there are few therapeutic options for its patients. Platelet-rich plasma is a treatment option for chronic pain. If proven to be effective in its intra-articular use, Platelet-rich plasma may help in the treatment of these patients. Goal: Primary objective: To compare effectiveness in improving pain and function and the medium-term tolerance (12 weeks) of intra-articular injection of Platelet-rich plasma versus intraarticular injection of triamcinolone hexacetonide in patients with symptomatic primary knee osteoarthritis. Secondary objective: To compare the medium-term effectiveness of intra-articular injection of Platelet-rich plasma versus intra-articular injection of triamcinolone hexacetonide to improve synovial hypertrophy and quality of life in these patients. Methods: A prospective randomized controlled double-blind study with three groups (each with n = 33) of patients with symptomatic osteoarthritis of knees who will receive intra-articular infiltration in a single moment. Patients will be allocated to one of three groups: 1) Platelet-rich plasma group: patients who will receive plasma; 2) triamcinolone hexacetonide Group: patients who will receive 40mg of triamcinolone hexacetonide; And 3) Isotonic saline solution group: patients who will receive isotonic saline solution. The patients will be evaluated by "blind" evaluators in 4 assessment times up to 12 weeks of follow-up through clinical assessment instruments (rest and movement pain, joint edema, goniometry, clinical improvement scale, quality of life questionnaire as the SF36), functional (Womac questionnaire, M. Lequesne Functional Knee Index, 6 min walk test, Time up and go test), and ultrasound test (quantitative and semiquantitative measurement of synovial hypertrophy and semiquantitative Power Doppler). Statistics: The following statistical tests will be used according to the need: Student's t test, Mann-whitney, Pearson's chi-square test and ANOVA for repeated measures. A statistical significance of 5% will be considered.

The purpose of this study is to evaluate the efficacy of intra-articular injections of combined hyaluronic acid and platelet-rich plasma in knee degenerative joint disease in improving joint function and reducing pain.

Knee and hip osteoarthritis (OA) is the most common cause of disability in the U.S. and affects more than 60% of adults over 65 years. As the burden of knee and hip OA increases among aging adults, more patients are deciding to have joint replacement surgery. However, no clear guidelines exist for patients to determine if or when to undergo total joint replacement (TJR). The investigators plan to develop a web-based system that will provide individualized patient OA Care Plans that will help patients make informed decisions about how to treat their arthritis. The investigators will be using this system with patients to see if they find it useful. The investigators believe that the OA Care plan will improve the process and quality of OA treatment decisions and the quality of OA care.

This study consists of a randomized, double-blind, placebo-controlled crossover trial with open label extension evaluating a topical natural health cream containing ß-caryophyllene alone and in combination with 0.025% capsicum oleoresin against placebo. At the end of the randomized controlled phase of the trial all participants will be given open-label combination cream to be administered over the subsequent 3 weeks. Primary Endpoint: Evaluation of improvement in pain interference as measured by the BPI in individuals who are experiencing pain due to osteoarthritis of the knee. Secondary Endpoints: Secondary endpoints are: Confirmation of safety of the topical cream when used daily over 10 weeks. Further evaluation will include overall patient satisfaction with the products tested.
