Osteoarthritis (OA), a highly prevalent disease, raised aggregate annual medical care expenditures in the U.S. by $185.5 billion according to researchers from Stony Brook University. Insurers footed $149.4 billion of the total medical spend and out-of-pocket (OOP) expenditures were $36.1 billion (2007 dollars). Results of the cost analysis study are published in the December issue of Arthritis & Rheumatism, a journal of the American College of Rheumatology. http://www.physorg.com/news178780955.html Medicine & Health Mon, 30 Nov 2009 05:23:06 EST news178780955 (PhysOrg.com) -- Researchers at the University of Toronto and the Hospital for Sick Children (SickKids) have found a pharmacological approach to treating the disease. The study is published in the November 15 advance online edition of Nature Medicine. http://www.physorg.com/news177671799.html Medicine & Health Tue, 17 Nov 2009 09:40:02 EST news177671799 Adults who had experienced physical abuse as children have 56 per cent higher odds of osteoarthritis compared to those who have not been abused, according to a new study by University of Toronto researchers. http://www.physorg.com/news176387584.html Medicine & Health Mon, 02 Nov 2009 12:50:06 EST news176387584 Researchers from Tufts University School of Medicine have determined that patients over 65 years of age with knee osteoarthritis (OA) who engage in regular Tai Chi exercise improve physical function and experience less pain. Tai Chi (Chuan) is a traditional style of Chinese martial arts that features slow, rhythmic movements to induce mental relaxation and enhance balance, strength, flexibility, and self-efficacy. Full findings of the study are published in the November issue of Arthritis Care & Research, a journal of the American College of Rheumatology. http://www.physorg.com/news176014700.html Medicine & Health Thu, 29 Oct 2009 06:30:01 EST news176014700 (PhysOrg.com) -- Damaged knee joints might one day be repaired with cartilage grown from stem cells in a laboratory, based on research by Professor Kyriacos Athanasiou, chair of the UC Davis Department of Biomedical Engineering and his colleagues. http://www.physorg.com/news175278162.html Medicine & Health Tue, 20 Oct 2009 17:40:01 EST news175278162 (PhysOrg.com) -- Here`s another good reason to lose even a moderate amount of weight: it could reduce your risk of developing osteoarthritis in your knees. http://www.physorg.com/news175195027.html Medicine & Health Mon, 19 Oct 2009 19:50:01 EST news175195027 Copper bracelets and magnetic wrist straps are ineffective in relieving arthritis pain, according to a new study led by a University of York academic. http://www.physorg.com/news174914289.html Medicine & Health Fri, 16 Oct 2009 12:18:44 EST news174914289 Despite twenty years of research on the use of electrostimulation techniques (TENS) for treatment of osteoarthritis in the knee, researchers still cannot say whether it reduces pain or physical disability.

While the study was in mice, the model closely mimics human osteoarthritis that develops following knee injuries, according to the study authors. http://www.physorg.com/news171987169.html Medicine & Health Sat, 12 Sep 2009 15:40:02 EST news171987169 A new study by researchers at the University of Iowa Hospitals and Clinics found that thigh muscle strength does not predict the occurrence of knee osteoarthritis (OA) uncovered in x-rays, but does predict incidence of painful or stiff knee OA. Women with the strongest quadriceps muscles appeared to be protected against the development of knee OA symptoms. Details of this study appear in the September issue of Arthritis Care & Research, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology. http://www.physorg.com/news170584634.html Medicine & Health Thu, 27 Aug 2009 10:00:01 EST news170584634 A study in the Aug. 15 issue of the Journal of Clinical Sleep Medicine shows that the use of cognitive behavioral therapy for insomnia (CBT-I) is an effective treatment for older patients with osteoarthritis and comorbid insomnia. http://www.physorg.com/news169644658.html Medicine & Health Sun, 16 Aug 2009 13:00:02 EST news169644658 (AP) -- Lucy the Labradoodle scoots along the ground to grab a bone. http://www.physorg.com/news169103016.html Medicine & Health Mon, 10 Aug 2009 06:04:13 EST news169103016 Osteoarthritis (OA), the most common joint disorder throughout the world and a leading cause of disability, is characterized by pain, impaired joint mobility, reduction of muscular strength and loss of joint function. Unlike most other common diseases, little is known about its origins, and factors predicting a severe disease course have not been identified. A new study, the first to establish a laboratory marker for the risk of severe OA, found that vascular cell adhesion molecule 1 (VCAM-1), was a strong predictor of hip and knee joint replacement due to severe OA. The study was published in the August issue of Arthritis & Rheumatism. http://www.physorg.com/news168153938.html Medicine & Health Thu, 30 Jul 2009 06:26:22 EST news168153938 A combination of biochemical and MRI markers will allow improved measurement of osteoarthritis (OA) progression.

The procedure appears to be cost-effective across all patient risk groups, and appeared more costly and less effective in low-volume centers than in high-volume centers. http://www.physorg.com/news164906963.html Medicine & Health Mon, 22 Jun 2009 18:30:02 EST news164906963 Osteoarthritis is commonly diagnosed in the late and irreversible stages, when treatment can only be expected to decrease pain and slow progression of disease. Because osteoarthritis is a widespread problem in dogs, horses and humans, doctors and veterinarians need a precise way to diagnose the disease early and accurately. Now, University of Missouri researchers are investigating potential biomarkers in dogs for early diagnosis of osteoarthritis, which could help identify patients at increased risk of developing osteoarthritis. http://www.physorg.com/news163862114.html Biology Wed, 10 Jun 2009 14:15:36 EST news163862114 Approximately one in four practicing clinicians appear to be aware of two major federally funded clinical trials of alternative therapies, and many do not express confidence in their ability to interpret research results, according to a report in the April 13 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. http://www.physorg.com/news158861206.html Medicine & Health Mon, 13 Apr 2009 17:07:16 EST news158861206 Rush University Medical Center is testing a new procedure for regenerating damaged articular cartilage in the knee joint to relieve the pain of osteoarthritis.
