Active clinical trials for "Osteoarthritis"

The purpose of the study is to evaluate the effectiveness of a device that delivers cold and intermittent compression as compared to ice and compressive wraps on patients who have undergone knee replacement.

Osteoarthritis disables approximately 10% of people who are 60 years or older and compromises the quality of life of more than 20 million Americans every year. Osteoarthritis is caused by the breakdown of cartilage that lines the bones at your joints from daily wear and tear and results in pain and restricted function. Total hip arthroplasty (THA) or total hip replacement, is currently one of the most successful and cost-effective treatments used to eliminate pain and restore function in those suffering from osteoarthritis. There are multiple ways to perform a THA. The main difference between each type is the point of incision in relation to a muscle on the outer surface of your hip bone: gluteus medius. The incision performed can be anterior (in front of the muscle), anterolateral (in front and to the side of the muscle), or posterior (from the back). Each of these approaches has its own advantages and disadvantages, but there is no evidence available that makes one better than the other. The purpose of this study is to determine which of the three approaches to THA is the most effective. The main outcome that will determine the most effective approach is the functional ability of the patients included in this study at 52 weeks. The investigators will also compare whether the patient's: length of hospital stay, use of assistive devices, need for revision surgery, ability to return to work, ability to relieve pain, complication rate, and quality of life. The investigators hypothesize that the anterior approach will be the most effective approach in reducing the rate of post-operative complications after THA.

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).

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.

Using magnetic resonance imaging (MRI), laboratory analyses and patient reported outcomes, the overall aim of this study is to investigate structural injuries and biochemical alterations in the acutely injured knee and to relate these findings to clinical outcomes at various time points.

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

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.

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.

Total knee arthroplasty (TKA) has a high success rate for addressing pain and improving function. However, in instances where incorrect positioning and malignment of the TKA components are observed, patients can experience a range of negative postoperative outcomes such as loss of thickness of polyethylene tibial bearings, eccentric loading, implant loosening, and eventual early revision. To avoid these complications, achieving a postoperative alignment within the range of 0°±3° of the mechanical axis is recommended. Manual intramedullary/extramedullary guides are not thought to be capable of consistently achieving axes in this range, and though computer-assisted navigation has shown superior results in comparison with conventional instrumentation, it is also limited by increased surgical times and no clear superiority in improving short-term clinical outcomes. Thus, there has been in a push in the orthopaedic community to create more precise technologies to aid in the reconstruction of the knee's mechanical axis. Patient-specific instrumentation (PSI), which uses anatomical data obtained primarily from pre-operative axial computed tomography (CT) or magnetic resonance imaging (MRI) to create disposable cutting jigs individualized to the patient's unique anatomy, was created with this goal. This study aims to compare the clinical results of conventional and patient-specific instruments in total knee arthroplasty.
