Active clinical trials for "Osteoarthritis"

The primary objective of this study is to determine the levels of proteins and/or cellular components of the synovial fluid that are indicative of microenvironment phenotypes of the osteoarthritic knee compared to unilateral unaffected joints pre-injection to 6 weeks post-Regenexx® SD treatment.

The purpose of this study is to evaluate efficacy and safety of SI000413 in patients with knee osteoarthritis by orally administration and to determine optimal dose.

The purpose of this study is to obtain patient oriented and clinically oriented physical function outcomes both pre-operatively and post-operatively in patients receiving a total knee arthroplasty.

This study is intended to gather medium (0-5 years) and long-term (6-10 years) information regarding the performance and safety of the commercially available Ceramax™ Ceramic on Ceramic Total Hip System. This is a two-phased study consisting of a clinical follow-up phase and a clinical outcomes phase. In Phase One (0-5 years), diagnostic, demographic and operative information will be gathered for each subject enrolled in this study. In addition, Harris Hip Evaluations, subjective evaluations and radiographs will be completed annually. In Phase Two (6 - 10 years), a subjective outcomes questionnaire and a SF-12 Health Survey will be mailed to subjects annually.

This study is aimed to determine the efficacy and the safety of the tourniquet reinflation after early tourniquet release in total knee arthroplasty, compared to the method of early deflation without reinflation. The investigators hypothesized that the reinflation after early release of the tourniquet would be effective in terms of improved visualization of the surgical field and decreased operation time and blood loss, whereas it would increase tourniquet-related complication due to longer tourniquet-use time.

Patients who present rhizarthrosis diagnostic will be randomized to be treated with chondroitin sulfate or placebo during 24 weeks to study the effect of the treatment with objective and subjective indicators of pain and sensibility.

Postoperative pain following total hip arthroplasty (THA) (1) is often considered moderate to severe and can therefore influence the postoperative course of event and result in delayed postoperative mobilization and prolonged hospitalization. It is therefore necessary to find the most optimal method for alleviation of pain for these patients. Traditionally, this has been managed by epidural analgesia, continuous peripheral nerve blocks, parental- or spinal opioids. Recently, Drs Kerr and Kohan at the Joint Orthopaedic Centre in Sydney, Australia developed a local infiltration analgesia (LIA) technique. The technique was introduced in Scandinavia during 2001 and has been shown to be efficacious during knee surgery. The LIA technique is based on a systemic infiltration of a mixture of a long-acting local anaesthetic (ropivacaine), a non steroidal anti-inflammatory drug (ketorolac), and epinephrine into the tissue around the surgical field to achieve satisfactory pain control with little physiological disturbance. A catheter is left from the skin and into the joint cavity, allowing repeated injection on the morning after surgery (10). Effective pain relief with early mobilization and reduced hospital stay has been reported following total knee arthroplasty and, recently, following unicompartmental knee arthroplasty. The aim of this study is to assess whether LIA technique is equi-efficacious to intrathecal morphine, the standard of care in our hospital.

The investigators will try to find any efficacy of platelet rich plasma injection for the treatment of osteoarthritis (OA) in the subtalar joint. Autologous platelet-secreted growth factors (GFs) may have therapeutic effects in OA capsular joints via multiple mechanisms. The investigators aim is to examine the effect of a platelet-derived preparation rich in growth factors(PRGFs) in OA of the subtalar joint, using parameters of pain, function, quality of life and safety.

Temporomandibular disorder (TMD) is the major cause of nondental pain in orofacial area. Laser therapy can be considered as one of the most popular methods of pain relief in TMD patients. The special features of laser light such as coherence, monochromaticity, and collimation can result in the ability of laser light to modify cellular metabolism, increase tissue repair and reduce edema and inflammation. The effectiveness of low level laser therapy in reducing the signs and symptoms of temporomandibular joint disorders has been investigated in a few studies. But, in most of the previous studies the etiology of TMD has not been considered in patient selection. Furthermore, there are some controversies in the results of these studies. According to our data, there is no study evaluating the effects of low level laser therapy on patients having TMJ osteoarthritis. The aim of this study is to evaluate the effectiveness of low level laser therapy in improving osteoarthritis of temporomandibular joint and also to evaluate the long term effects of laser therapy on the morphology of the joint.

Study is prospective and multi-center. Study will include 100 to 200 patients across up to 20 sites.The study sites will be located in the United States.The study objective is to evaluate the safety and performance of the ConforMIS iUni® Unicompartmental Knee Resurfacing Device in patients with single compartment osteoarthritis.
