Active clinical trials for "Osteoarthritis"

The total knee arthroplasty (TKA) is a well established option for the treatment of osteoarthritis in this joint. Nevertheless, there are still some concerns related to the peri-operative management of elderly patients, highlighting the complications related to medical comorbidity and bleeding produced by surgery. One of the proposed methods to decrease postoperative bleeding, which has been accumulating favorable evidence, is the use of tranexamic acid (TA). Several studies (including prospective randomized trials with placebo group) showed excellent results with TA intravenous administration during TKA, reducing the amount of bleeding, the drop in hemoglobin and the need for blood transfusion. Another alternative to minimize bleeding is the use of topical hemostatic agent Floseal®, composed of thrombin and bovine gelatin. This substance has presented significant benefits on bleeding control in several areas of medicine, including orthopedic surgery, but no action has yet been established in TKA. The main objective is to evaluate the amount of bleeding, the drop in hemoglobin and the need for blood transfusion after TKA, comparing the use of TA, Floseal® and a control group. The secondary objective is to evaluate the rate of adverse events in the studied groups.

M.M.A.TECH Ltd. product is an Acetabular Liner Family produced of an advanced polyimide - MP-1™. M.M.A.TECH Ltd. produces the Liners according to EN ISO 13485:2012 approved manufacturing process and supplies them to the customer. The aim of this study is to evaluate, in the frame of PMCF, the safety and performance of using AL-X MP1 Polyimide Acetabular liners in Total Hip Replacement surgery by clinical following up of patients for a period of 2 years .

Introduction; reception must be understood as the offered attention within the relationship between a healthcare worker and the patient, including attitudes of inclusion, hearing, valorization of complains and identification of needs, being these individual collective. As a part of this process, communication is a primary and indispensable toll through which the healthcare team and the patient interchange information. Objective: to evaluate the influence of perception of patients suffering of knee osteoarthritis over fear, catastrophizing of pain and effectiveness, related to intra-articular injection od corticosteroids. Material and method: it will be performed a prospective, controlled and randomized study eith a blind evaluator on patients with symptomatic knee osteoarthritis submitted to joint injection. A hundred patients suffering of symptomatic knee osteoarthritis coming from the outpatient area of Rheumatology Division of Federal University of Sao Paulo (UNIFESP) will be evaluated, 50 belonging to the intervention group (reception) and 50 to a control group.

The purpose of the study is to investigate fixation to bone and the clinical results following shoulder resurfacing arthroplasty. The study will compare results between an implant made of Cobalt-Chrome(CoCr) and an implant made in pyrocarbon.

This study aims to evaluate various methods of measuring pain relief in subjects who have chronic OA of the knee. After a 1 week of wash-out from existing therapy, subjects will be treated in a blinded fashion for 1 week with either naproxen (3 days at 250 mg twice a day followed by 4 days at 500 mg twice a day) or placebo. After the first week of treatment, subjects will have another week of wash-out followed by a second period of 1 week of the alternate treatment. Subjects will not be allowed to use oral non-steroidal anti-inflammatory drugs (NSAIDs) or other oral analgesics, or topical medications on their target knees during the study. Acetaminophen will be allowed as a rescue medication.

The purpose of this study is to verify the efficacy and safety of acupuncture treatments (Individualized, Standardized acupuncture) for patients with knee osteoarthritis (OA).

It remains unknown if a concomitant arthroscopic knee debridement would increase the benefits of surgery (quality of life and functional ability) for young active patients with medial compartment OA of the knee and varus alignmen. This additional procedure has a low incidence of morbidity and would potentially allow for treatment of meniscal tears and articular damage, as well as joint lavage to remove debris and inflammatory factors. A trial is needed to determine whether HTO with concomitant knee arthroscopy will result in better overall outcomes for this patient group.The objective is to compare the quality of life, functional status, pain, and swelling of patients who undergo an HTO with or without a concomitant knee joint arthroscopy to address additional joint pathology

251 consecutive patients with knee arthrosis were randomized to one of three interventions: Four weekly injections of 2 ml isotonic saline (placebo), 2 ml sodium hyaluronate (hyaluronan) or 20 ml isotonic saline (excessive saline). They all suffered from clinically and radiologically verified arthrosis of the knee with daily pain that did not respond to treatment with analgetics. Results were evaluated at weeks 1,2,3,4,8,12,16 and 26. Biochemical markers for bone and cartilage degradation were measured in urine/blood.

Other research studies have shown that the levels of metals in the blood are slightly increased after patients receive a total hip replacement. We want to learn whether these elevated levels are associated with any adverse effects. We hope this study will help us identify which type of patients have elevated levels of metal in their blood.

To determine whether platelet-rich-plasma (PRP) or HA (hyaluronic acid)injection into synovitis in osteoarthritis(OA) knee can achieve improvement in knee function and reduce synovitis.
