Stem Cell Cartilage Offers Hope to Osteoarthritis Sufferers
Cartilage grown from stem cells in a laboratory may one day repair damaged knees, according to research from UC Davis Department of Biomedical Engineering. Lead author, Kyriacos Athanasiou and his team used adult stem cells from bone marrow and skin as well as human embryonic stem cells to grow cartilage tissue in the lab. Now they are experimenting with various chemical and mechanical stimuli to improve its... ( Read more about Stem Cell Cartilage Offers Hope to Osteoarthritis Sufferers )
Drug May Extend Life of Arthritic Knees and Hips
An osteoporosis drug that is the first ever known to prevent cartilage loss following injury to a joint may also regenerate some cartilage that has been lost to osteoarthritis, according to research presented at the American Society for Bone and Mineral Research in Denver. Though this initial study was done on mice, study authors claim that the model closely resembles human osteoarthritis that develops...

Orthopedic and Dental Implants Aided by New Coating
A newly developed electrochemical process for coating metal implants vastly improves their functionality, longevity, and integration into the body, according to research conducted at Tel Aviv University. The new process has the potential to greatly improve the lives of people who have undergone joint replacement surgeries, improving their ability to walk, run and ultimately avoid the body's rejection of the...

Metal-Particle Inflammation Causes Joint-Implant FailureThe very joint implants that bring pain relief and restore freedom of motion to patients’ extremities can be their own undoing, setting off a metal-induced immunological defense mechanism that causes the implants to loosen and fail, according to a recent study. Hip Replacements Fail Due to Implant Irregularities, Infection
Contrary to conventional wisdom, total hip replacements fail just as much, if not more so, from implant dislocation or infection than from the wearing out of the bearing surface, according to recent research.
While many thousands of people experiencing extreme pain from debilitating hip disease and other hip problems are helped each year with hip replacements that provide long-term relief, the study in the...

The new material, which is expected to be especially helpful to patients facing bone-implant surgery, was developed at the University of Warwick... ( Read more about Synthetic Bone May Assist Implant Surgery ) Biological Materials Seen Ousting Joint ReplacementsJoint replacements are a major dimension of the orthopedics specialty, but they may be replaced in about 15 years by biological products that stimulate tissue and bone growth, according to a leading prognosticator. "We will be a little in the 'Star Trek' era, potentially," said Paul Olson, director of Viscogliosi Bros. LLC, a New York investment bank that specializes in orthopedics investment. He spoke... ( Read more about Biological Materials Seen Ousting Joint Replacements ) Technique Aids Joint ReplacementsA computer-aided bone-implant technique is coming on line that will increase the accuracy of implant insertions and decrease operating room time for hip, shoulder, knee and ankle replacements - especially for younger patients. The novel technology relies on software newly developed by the Human Mobility Research Center in Kingston, Ontario. It also depends on computed tomography (CT) scans of a patient's... ( Read more about Technique Aids Joint Replacements ) Precautions for the elderly: Hip FractureWhat are Hip Fractures? Hip Fracture is a fracture or a crack or break in the proximal end of the femur near where the bone meets the hip. The term Hip fracture is used to describe any of 4 types of fractures within the bone in the hip area. 90% of hip fractures occur due to direct impact against the hip joint, usually as a result of a fall. ( Read more about Precautions for the elderly: Hip Fracture )Hispanics and OsteoporosisHispanics are the nation’s largest minority group, and they are also the fastest growing group, accounting for about half of the growth in the U.S. population since 2000. Thus Hispanic healthcare is an increasing concern that a lot of doctors are focusing their attention onto. The growth of the Hispanic population has not been accompanied by an improvement in Hispanic healthcare. Of particular concern is... ( Read more about Hispanics and Osteoporosis ) |
