Osteoarthritis, which affects at least 20 percent of adults in the United States, leads to deterioration of cartilage, the rubbery tissue that prevents bones from rubbing together. By studying the molecular properties of cartilage, MIT engineers have now discovered how the earliest stages of arthritis make the tissue more susceptible to damage from physical activities such as running or jumping. http://medicalxpress.com/news/2013-04-earliest-stages-arthritis-high-impact-worsen.html Arthritis & Rheumatism Wed, 17 Apr 2013 15:02:16 EST news285429716 (HealthDay)—Across much of the United States, the winter months are a fun time filled with falling flakes and holiday cheer.

While previous research has focused on biomechanical differences as the main source of these problems, a new study suggests another distinction that could play a role: changes across the menstrual cycle in nerves that control muscle activity. The finding may eventually lead to new ways to prevent knee problems in female athletes. http://medicalxpress.com/news/2012-10-nerve-muscle-vary-menstrual-higher.html Medical research Thu, 11 Oct 2012 07:53:50 EST news269160824 (HealthDay) -- Sports-related kidney injuries occur significantly less frequently than other injuries in high school athletes, according to a study published online June 18 in Pediatrics. http://medicalxpress.com/news/2012-06-sports-related-kidney-injuries-rare-high.html Pediatrics Mon, 18 Jun 2012 13:40:01 EST news259243629 Women are more prone to knee injuries than men, and the findings of a new study suggest this may involve more than just differences in muscular and skeletal structure – it shows that males and females also differ in the way they transmit the nerve impulses that control muscle force. http://medicalxpress.com/news/2012-04-knee-injuries-women-linked-motion.html Diseases, Conditions, Syndromes Tue, 17 Apr 2012 12:13:52 EST news253883626 A cartilage gel being developed by tissue engineers and biochemists at the University of Sydney could bring increased mobility to people living with debilitating sports injuries. http://medicalxpress.com/news/2012-03-cartilage-gel-injuries-sporting-chance.html Medical research Thu, 08 Mar 2012 05:59:30 EST news250408763 Kids treated more than 150 days after an Anterior Cruciate Ligament (ACL) injury have higher rates of other knee injuries, including medial meniscal tears, say researchers presenting at the American Orthopaedic Society for Sports Medicine's (AOSSM) Specialty Day in San Francisco, CA. http://medicalxpress.com/news/2012-02-acl-reconstruction-kids-higher-knee.html Other Sat, 11 Feb 2012 09:28:10 EST news248174873 Primary Anterior Cruciate Ligament (ACL) reconstruction improves quality of life and sports functionality for athletes, according to research presented today at the American Orthopaedic Society for Sports Medicine's Specialty Day in San Francisco, CA. http://medicalxpress.com/news/2012-02-acl-knee-treatments.html Other Sat, 11 Feb 2012 09:26:19 EST news248174772 When William Murphy works with some of the most powerful tools in biology, he thinks about making tools that can fit together.
