Active clinical trials for "Osteoarthritis, Knee"

The purpose of this study is to determine 1) the effective dosage of intra-articular tranexamic acid injection for controlling blood loss and blood transfusion requirement in conventional total knee replacement, and 2) whether the blood loss reduction effect depended on the dose of tranexamic acid used.

To determine whether plai cream is effective in treating mild to moderate degrees of osteoarthritis of the knee in the elderly patient compared with placebo cream.

Background: In the early phase after a total knee replacement (TKA), patients experience multi-level weakness in the operated leg, which is caused primarily by reduced central (CNS) activation failure of the muscles - especially the knee extensors. This considerable loss of muscle strength relates to reduced functional performance. The investigators recently reported that early-commenced physiotherapy, including progressive strength training performed in machines, seems feasible after TKA. The question is, if neuromuscular activity of the muscles in the operated leg, elicited during strength training in machines, can be reached during strength training in more simple forms? Many clinicians are faced with the problem of not having strength training equipment at their institution, or having to prescribe simple strength training exercises for home-based training. Purpose and hypothesis: The purpose of this study is to determine which strength training exercises that activate the muscles in the operated leg the most after TKA. The hypothesis is that strength training exercises performed in machines is more effective compared to strength training performed in more simple forms (using elastic bands or own body weight, etc.). Participants and methods: Twenty participants with a unilateral TKA, operated between 4 to 8 weeks prior to the first investigation, will be included. The participants are investigated twice. During the first investigation, the absolute load (kilograms) corresponding to 10 Repetition Maximum (RM) (a load that can be lifted exactly 10 times) will be determined for all the exercises. At least 72 hours later, the participants will undergo an electromyographic analysis, which determines the neuromuscular activity of the thigh muscles in the operated leg. Ethical issues: From a pilot study, the investigators found that strength training exercises commenced early after TKA seems feasible as the exercises did not increase knee joint swelling or knee pain. None of the financial supporters, or any of the authors, have any potential conflicts of interest with regard to the study.

we tested the effect of adding the mobilization with movement to the traditional physical therapy program on pain, ROM and functional disability in patients with knee OA. study hypothesis: there will be no significant difference between traditional physical therapy program and the mobilization with movement plus the traditional physical therapy program on pain, ROM and functional disability in patients with knee OA

This is a randomized, double-blind study to compare the efficacy and safety of LAYLA tablet and Joins tablet in the treatment of osteoarthritis of the knee.

Osteoarthritis (OA) is a highly prevalent and disabling disease. It is estimated that by 2030 the prevalence of symptomatic OA could reach 30% of the population above 60 years. It is associated with significant morbidity being one of the most common causes of joint pain, functional disability and compromised quality of life. This randomised controlled trial will investigate the effect of low-level laser therapy (LLLT) and static stretching exercises, as monotherapy and in combination, on pain, quality of life, function, mobility, knee range of motion (KROM) and hamstring length in participants with knee OA. This study will involve 145 people aged 50-75 years with symptomatic radiographic knee OA and will consist of two types of treatments: Low-level laser therapy (LLLT) and stretching exercises. The patients will be randomly allocated to five study groups LLLT active+Stretch, LLLT placebo+Stretch, Stretch, LLLT and Control (with n=29 each). Treatment frequency will be three sessions/week for all active groups. LLLT will involve the use of a Galium-Arsenide laser (904nm, 40 milliwatts, 3 Joules/point, 27 Joules/knee) over 24 sessions for the monotherapy group and 9 sessions for the LLLT+Stretch groups. Stretching will consist of seven exercises completed over 24 sessions. The control group will receive a booklet. The primary outcome is pain measured by Visual Analogue Scale. Secondary outcomes included quality of life assessed by Western Ontario and McMaster Universities Arthritis Index (WOMAC), function by Lequesne Algofunctional Index, mobility by Timed Up and Go Test (TUG), KROM by goniometry of knee flexion and hamstring shortening by popliteal angle. The statistical method will follow the principles of per-protocol analysis.

Knee osteoarthritis (OA) is now recognized as a major health problem. It is the number one cause of lower extremity disability and has significant deleterious effects on quality of life. While there are numerous therapies available for knee OA, most have limited efficacy. Of particular concern, is the widespread use of nonsteroidal anti-inflammatory drugs (NSAIDs) for this disorder. Veterans, as a group, are at high risk for both gastrointestinal and cardiovascular NSAID-induced complications. In this study the investigators propose to examine whether replacing NSAIDs with cognitive behavioral therapy delivered by telephone is an effective strategy for Veterans with knee OA. Telephone-administered therapy is particularly appealing since Veterans with knee OA are more likely to have limited mobility. If successful, this program may result in significant cost-savings for both Veterans (decreased co-pays and transportation costs) and the VA (decreased hospitalizations due to NSAID induced toxicity).

This prospective single-center study will evaluate the safety and tolerability of a single dose of "APS(TM)" treated patients with OA of the knee who have failed conservative OA therapy. The study will also evaluate efficacy by assessing patient pain and functionality.

The rehabilitation protocols in knee osteoarthritis are often difficult to be applied in elderly patients because they are long lasting and need the constant participation of patients. To rapidly improve the motor performances of patients it is possible to use the mechanical vibration applied to individual muscles using a protocol called "repeated muscle vibration" (rMV). The purpose of this single-blind randomized placebo-controlled study is to evaluate the effectiveness of the repeated muscle vibration (rMV) in terms of increasing the ability of the patients affected by knee osteoarthritis, compared to an ineffective treatment, considered as a placebo. Each subject, randomly assigned to either the group 1 (study group) or placebo-treatment (group 2)is administered 3 daily applications of rMV of 10 minutes each, for 3 consecutive days. Between two successive applications it's observed a break of at least 15 seconds. The probe of the specific instrument (Cro ® System) is placed near the supero-medial margin of the patella, on both quadriceps. Patients in group 2 (control group) are subjected to a treatment with muscle released in which the probe of the same instrument is approached to the quadriceps, without making contact. The instrument in these conditions emits a buzz but not provokes muscle vibration. The primary outcome of the study is to determine the changing in patients' ability (as measured by WOMAC scale = Western Ontario and McMaster Universities Osteoarthritis Index) . The secondary outcomes of the study are the assessment of changing of patients' balance and risk of falling (as measured by the Tinetti scale) and assessment of changing of patients' quality of life (as measured by EQ-VAS= EuroQuality of Life-VAS scale).Outcome measures are administered at baseline (T0), at the end of the treatment protocol (T1), at 1 month (T2), 3 months (T3) after the end of treatment and 6 months (T4) after the end of the treatment.

Osteoarthritis (OA) is a progressive, chronic disease affecting more than 20 million Americans. There is no known cure for OA and management includes pain control and prevention of functional decline. Purpose: To investigate the immediate effects of a shock absorbing insole (SAI) placed in the shoe on knee pain, functional mobility and lower extremity biomechanics.
