Active clinical trials for "Osteoarthritis"

This study evaluates the effects of various types of ultrasound therapy: continuous, pulsed, sham ultrasound and ultrasound combined with electrotherapy in patients with hip osteoarthritis. Beside ultrasound therapy, patients received usual physiotherapy (balneotherapy, exercise and massage) either.

The objective of this study is to evaluate the efficacy and safety of Chondron (Autologus Chondrocyte) in patients with cartilage defects in their ankle for 18 months

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.

Previous study showed that Guli capsule could suppress the adjuvant multiple arthritis; have inhibitory effect on carrageenan gelatinous and formaldehyde foot swelling; improve the symptom of osteoporosis patients; and improve pain and limited joint activities of rheumatoid patients. To further verify the clinical effect of Guli capsule in the treatment of knee osteoarthritis, the investigators perform this multi-center clinical study.

Primary aim: evaluate efficacy of subcutaneous injection of etanercept for moderate and severe knee osteoarthritis. Second aim: investigate the potentiality of serum cytokines (TNF-α, Interleukin 1-α (IL1-α), IL1-β, matrix metalloproteinases1 (MMP1), MMP13) to predict the response of subcutaneous injection of etanercept for moderate and severe knee osteoarthritis.

In France, osteoarthritis affects about 10 million people and knee osteoarthritis represents 35% of cases. It is thought that more than 2.5 million people older than 65 years have knee osteoarthritis. Currently, osteoarthritis management is based on three major axes: Non-pharmacological means, such as patient education, loss of weight and physical activity General pharmacological treatments: mainly paracetamol and then schedule II and III painkillers as well as nonsteroidal anti-inflammatory agent. Intra-articular pharmacological treatments: Intra-articular injections of corticosteroids: they are recommended during hydarthrotic flare-ups Intra-articular injections of hyaluronic acid (HA) (viscosupplementation) in the absence of intra-articular effusion. However, their efficacy is questioned by most experts in the case of symptomatic knee osteoarthrosis. Sometimes, surgery is the only therapeutic option. However, besides the fact of exposing patients, who are sometimes frail, to several peri- and post-operative complications, the recovery rate (variable according to the prosthesis type and ranging from 5% to 25% at 9 years) in an ageing population justifies waiting as much as possible before surgery. Therefore, it is important to test new therapeutic options for symptomatic osteoarthrosis that will allow postponing the surgical treatment. The use of botulinum toxin (BoNT-A) could thus represents an interesting alternative. BoNT-A is habitually used by intra-muscular injection for its myorelaxant effect in the management of painful reactive periarticular muscle contractures. However, BoNT-A has also antalgic activity independently of the myorelaxant effect. This allows explaining in part the antalgic effect of intra-articular BoNT-A injection. In the literature, six randomized controlled studies (RCS) have compared BoNT-A and intra-articular injections of corticosteroids, hyaluronic acid, or placebo. Only two RCS concerned knee osteoarthritis and compared BoNT-A to corticosteroids and a placebo, respectively, with a significant antalgic effect only in the groups treated with BoNT-A. No study has compared yet the intra-articular injection of BoNT-A to the viscosupplementation by HA in knee osteoarthritis and this is the aim of this trial.

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.

The purpose of this study is to evaluate the time to total hip replacement in patients with hip osteoarthritis going through both a supervised exercise program and patient education compared to patients going through patient education only. The null hypothesis is: There are no differences in time to total hip replacement between patients with hip osteoarthritis who went through a 12 week supervised exercise program and patient education compared to patients who went through patient education only. Material and methods: 109 patients with both symptomatically and radiographically verified hip osteoarthritis were included in this randomized controlled trial between april 2005 and october 2007. They were randomized to either a 12 week supervised exercise program and patient education (n=55) or patient education only (n=54). Information on if and when total hip replacement is performed will be collected between April 1st and May 1st. Time since inclusion to follow-up will range from 3.5 to 6 years. Data will be collected directly from the study participants by telephone. The main outcome is time to total hip replacement. Status: This study is a prolongation of an on-going RCT (3a-2005-NAR) using clinical outcomes to evaluate the effect of supervised exercise and patient education. The study will be carried out: NAR-Department of Orthopedics, Ullevaal University Hospital.

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.

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.
