The meniscus is a rubber-like, crescent moon-shaped cartilage cushion that sits between the leg and thigh bone. Each knee has two menisci: one on the inside of the knee joint and one on the outside. In recent years, more children have been diagnosed with tears to this area (meniscal tears); however, according to a literature review published in the November 2009 issue of the Journal of the American Academy of Orthopaedic Surgeons (JAAOS), prospects for a full recovery are high. http://www.physorg.com/news176400523.html Medicine & Health Mon, 02 Nov 2009 19:40:01 EST news176400523 Jojanneke Jukes of the University of Twente, The Netherlands, has succeeded in growing bone tissue with the help of embryonic stem cells for the first time. http://www.physorg.com/news175447422.html Medicine & Health Thu, 22 Oct 2009 16:40:02 EST news175447422 (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 A recent United States Army study found that excessive bone growth, also known as heterotopic ossificiation (HO), affects up to 70 percent of soldiers who are severely wounded during combat. A much smaller percentage of the civilian population also suffers from HO following trauma or invasive surgery. The excessive bone forms within muscles and other tissues causing severe pain, reduced mobility and even local paralysis if untreated. http://www.physorg.com/news172924973.html Medicine & Health Wed, 23 Sep 2009 12:00:05 EST news172924973 An existing osteoporosis drug is the first ever found to prevent cartilage loss from osteoarthritis following injury to a joint, and may also regenerate some cartilage that has been lost to osteoarthritis, according to an early study presented today at the annual meeting of the American Society for Bone and Mineral Research in Denver.
