Active clinical trials for "Osteoarthritis, Knee"

Hyaluronic acid (HA) is a major component of synovial fluid, to which it confers viscosity and elasticity. It has been shown that the rheological properties of the synovial fluid decrease in patients with osteoarthritis. Intra-articular injections of hyaluronic acid represents a commonly used therapeutic option to relieve osteoarthritic symptoms, by exerting a mechanical action on cartilaginous structures of the joints, thus leading to reduced pain and improved joint function. Platelet-rich Plasma is an autologous product prepared from the patient's own blood. Potential benefits of platelet-rich plasma for the treatment of cartilage defects have been suggested by many in vitro and animal studies. There are an increasing number of clinical studies assessing the benefits of platelet rich plasma in the treatment of osteoarthritis, showing that platelet rich plasma improves symptoms with no serious adverse events reported. On the basis of the above, HA and platelet-rich plasma have the potential to provide added benefits in osteoarthritis symptoms when combined, in particular in patients who have had previous intra-articular HA treatment but who are still experiencing pain. Preliminary evidence to this effect was presented at the 2014 Annual Congress of the French Rheumatology Society by a group of French investigators. Renevier and Marc enrolled patients who had not experienced adequate symptom relief from previous intra-articular HA treatment and treated them with HA plus platelet-rich plasma prepared using A-CP HA Kit. Of the 71 patients treated, approximately 90% were classified as responders based on the OMERACT-OARSI criteria. The A-CP HA Kit allows for the preparation of a homogenous solution of platelet-rich plasma and HA, intended to be injected intra-articularly for the treatment of pain in osteoarthritis. In patients who had previous intra-articular HA treatment but who are still experiencing pain, treatment with HA plus platelet rich plasma could provide a safe and reproducible option before surgery.

This is a two-phase multicenter, double-blind, randomized, prospective evaluation of intra-articular injection(s) comparing APS to intra-articular HA injection(s). The maximum study duration for each subject will be 62 months; 60 months from treatment to last follow-up, and two additional months if the maximum visit window is realized. A total of 246 patients will be enrolled. These patients will meet specific inclusion and exclusion criteria, but can be generally characterized as patients with painful unilateral knee OA who have been unable to achieve satisfactory pain relief with previous conservative OA treatment.

Osteoarthritis (OA) is one of the most common joint diseases that is considered a chronic degenerative disorder. There is no effective therapy available today. This prospective clinical trial is designed in an attempt to study the efficacy of mesenchymal stem cells with platelet rich plasma in knee osteoarthritis.

This is a multi-center, randomized, open-label, parallel-arm phase IV clinical study, for which a total of 300 patients with mild to moderate knee osteoarthritis will be enrolled. In the first 4 weeks (run-in period), the subjects will receive on-demand treatment with Diclofenac Sodium Sustained Release Tablets (DICL-SR) 75mg, quaque die（QD）. After the run-in period, the subjects, if their knee pain has not worsened to a level requiring surgical treatment, will be randomized to two groups in 1:1 ratio: one group receiving Artz® via intra-articular injection (once weekly, for 5 consecutive weeks) in combination with DICL-SR 75mg,quaque die（QD）, for 12 consecutive weeks on demand. The other group receiving DICL-SR 75mg alone,quaque die（QD）, for 12 consecutive weeks on demand. DICL-SR 75mg quaque die（QD） may be administered to the subjects of both groups on demand as long as they have a knee pain. If the knee pain has disappeared, this drug may be withdrawn. However, if the pain occurs again and requires treatment, oral administration of DICL-SR may be resumed. A subject is allowed to withdraw from this study prematurely if unable to tolerate the adverse effects. A total of 8 visits have been scheduled for this study, including Visit 1/screening period (Week -4), Visit 2/baseline (Week 0), Visit 3 (Week 1), Visit 4 (Week 2), Visit 5 (Week 3), Visit 6 (Week 4), Visit 7 (Week 8) and Visit 8 (Week 12). A total of 300 subjects will participate in this study at 6 to 8 centers in China, and patient enrollment is expected to take up to 12 months.

Knee osteoarthritis(OA), also known as degenerative arthritis, have affected a lot of people. Patients with severe osteoarthritis frequently develop one or more of the typically following symptoms: joint pain, stiffness, activity with joint friction noise, limited mobility, such as difficulty walking and climbing. Now there are many western medicine treatments including symptom relief and joint cartilage protective agents for OA, but the results have not yet satisfied. TCM treatment of osteoarthritis has remarkable curative effect and unique advantage.Tong-Luo-Qu-Tong Plaster is a common method to treat osteoarthritis of the knee for thousands of years in China. It lacked a large sample randomised, double-blind, parallel positive controlled, multicenter clinical trial, and the clinical evidence of Tong-Luo-Qu-Tong Plaster for Knee Osteoarthritis need to be further completed.

It is estimated that nearly 27 million US adults have osteoarthritis (OA) and suffer from pain . Pulsed Radio Frequency (PRF) is one method that has been successfully used in treatment of various etiologies of pain. However there are limited studies and research that prove its effectiveness in treating articular pain. The proposed study's primary aim is determining if PRF is an effective treatment for chronic osteoarthritic knee pain. This study hypothesizes that PRF has analgesic properties immediately after treatment and at least 3 months afterwards compared to control treatment with physical therapy. Additionally this research project addresses several other objectives including: Provide a controlled study to determine the effectiveness of PRF for intra-articular pain Determine how effective PRF is 1 month and 3 months after treatment for articular pain. Further scientific evidence on the overall effectiveness of PRF Provide evidence that PRF likely has other mechanism of action besides direct nerve stimulation of inhibitory pain pathways. Compare the effectiveness of PRF vs Physical Therapy in treating chronic knee osteoarthritis.

3VM1001 is a topical cream that may be useful for the treatment of chronic osteoarthritis of the knee. This proof of concept study is a randomized, placebo-controlled, double-blind study to compare treatment with 3VM1001 cream to an inactive cream placebo. Subjects will self-treat for 30 days.

The present study is designed to test the hypothesis that Intra-Articular Hyaluronic Acid (IAHA) is superior to placebo in slowing structural progression and on long term symptomatic effect in primary knee Osteoarthritis (OA) patients. The investigators will perform a multicenter double-blind, randomized, placebo-controlled, parallel group trial.

Safety & Efficacy of FloGraft (Micronized Human Amnion Chorion Membrane)® in Adults With Pain Due to Osteoarthritis of the Knee.

This multicenter clinical trial aims to investigate the exact effect of drainage use for osteoarthritis patients in total knee arthroplasty (TKA) on post-operative performance.
