Cayenne Medical, Inc., a privately held sports medicine company based in Scottsdale, announced the commercial launch of its CrossFix™ System for the repair of meniscal tears at the American Orthopaedic Society for Sports Medicine (AOSSM) annual meeting in Keystone, Colorado last week. The CrossFix™ system offers surgeons the benefits of both open suturing and arthroscopic meniscal repair. The technology replicates results from "gold standard" open suturing techniques but through a faster and less invasive all-inside method. Unlike traditional all-inside meniscal repair devices, the CrossFix™ system leaves no plastic implants behind, thereby reducing risk of injury over time.
Researchers at Rush University Medical Center are testing a novel regimen of hip-muscle exercises to decrease the load on the knee joints in patients with osteoarthritis. The goal is not only to relieve pain but also, possibly, to halt progression of the disease. "Each time you take a step, a load, or force, is placed on the knee joints. How much load depends not just on your weight, but also on the way you walk and the alignment of your leg, " said Laura Thorp, PhD, assistant professor of anatomy and cell biology at Rush Medical College and principal investigator for the study. "If we can appropriately alter the gait patterns of patients with osteoarthritis, we can minimize the load and relieve pain.
In the July 15th cover story of G and D, a research team led by Dr. Eric Olson at the UT Southwestern Medical Center at Dallas reports that the class I histone deacetylase 8 (HDAC8) enzyme regulates gene expression in the developing vertebrate skull. HDAC8 overexpression is associated with a poor prognosis in human neuroblastoma patients. "As there are many different isoforms of histone deacetylases, it is crucial to understand the specific function of each -- with the putative goal of targeting a specific subset for a specific disease process, " explains Dr. Mike Haberland, lead author on the study. Dr. Olson's team explored the role of HDAC8 in verterbrate skull morphogenesis, using a strain of knockout mice specifically lacking HDAC8 in cranial neural crest cells.
While total knee surgery is a common procedure with a high success rate in the US, getting a second opinion is still recommended. Each surgeon has had a specific training and education, and more experience with certain procedures over others. Some surgeons embrace new technologies and methods while others are more traditional in their practice. Furthermore, you want to feel comfortable with your surgeon. Taking the additional steps to research, interview, and visit more than one doctor can pay off in the long run. Here are three scenarios that illustrate why getting a second opinion for a total knee replacement can save you time, money, and medical complications.
Risks Of Delaying Anterior Cruciate Ligament Reconstruction In Young Athletes May Be Too High, Study Shows
More and more children are participating and getting hurt playing sports each year. A new study presented at the American Orthopaedic Society for Sports Medicine's (AOSSM) Annual Meeting in Keystone, Colorado, (July 9-12) details the benefits and risks of repairing a torn anterior cruciate ligament (ACL) in young athletes under the age of 14. "The risk of inducing a growth disturbance with early reconstruction of a torn ACL must be balanced against the risk of further knee damage by delaying treatment until closer to skeletal maturity. Our study measured the independent risk factors for and relative risk of meniscal and chondral injuries in pediatric ACL patients, " said author, Theodore J.
WHAT: Food prices rose by 5.5 percent in the past year and are expected to increase up to an additional 4 percent in 2009. Americans are seeking to get the most out of their dollar, and since together, dairy foods provide a unique package of nine essential nutrients, they are a nutritional bang for the buck. In a supplement to the current issue of the Journal of the American College of Nutrition (JACN), several prominent nutrition researchers weigh in on an updated review of the health benefits of consuming dairy foods. This supplement further contributes to the well-established evidence that consuming the recommended servings of dairy foods each day is a convenient and affordable way to get several key nutrients that many Americans do not consume enough.
