Latest Cartilage Stories

The University of Pennsylvania Cartilage injuries are difficult to repair. Current surgical options generally involve taking a piece from another part of the injured joint and patching over the damaged area, but this approach involves damaging healthy cartilage, and a person’s cartilage may still deteriorate with age. Bioengineers are interested in finding innovative ways to grow new cartilage from a patient’s own stem cells, and, thanks to a new study from the University of...

In the future, joint replacement surgery might be avoidable Scientists at Johns Hopkins have turned their view of osteoarthritis (OA) inside out. Literally. Instead of seeing the painful degenerative disease as a problem primarily of the cartilage that cushions joints, they now have evidence that the bone underneath the cartilage is also a key player and exacerbates the damage. In a proof-of-concept experiment, they found that blocking the action of a critical bone regulation protein in...

Researchers at Micro Orthopaedics, Zhongnan Hospital of Wuhan University, led by Dr. Ai-xi Yu, have suggested that articular cartilage defects can be repaired by a novel thermo-sensitive injectable hydrogel engineered with gene modified bone marrow mesenchymal stromal cells (BMSCs). The chitosan and polyvinyl alcohol composite hydrogel containing hTGFβ-1 gene modified BMSCs was injected into rabbits with defective articular cartilage. Sixteen weeks later the defected cartilage regenerated...

To better understand the onset and progression of osteoarthritis, Nadeen Chahine, PhD, and collaborators at other institutions looked at cells from articular cartilage using atomic force microscopy (AFM). MANHASSET, NY (PRWEB) April 19, 2013 A researcher at The Feinstein Institute for Medical Research has discovered additional mechanical properties of articular cartilage, a protective cartilage on the ends of bones that wears down over time, resulting in the development of osteoarthritis....

Jason Pierce, MSN, MBA, RN for redOrbit.com – Your Universe Online A new paper published in the Biophysical Journal explains why cartilage may be more susceptible to damage from high impact physical activities such as jumping or running during the early stages of osteoarthritis. The results could lead to early diagnostic tests or new designs for replacement cartilage. Cartilage can be found in the joints between bones. It is a flexible tissue protecting the bones from rubbing...

Michael Harper for redOrbit.com – Your Universe Online It’s hard not to see 3D printing as the beginning of a bright new future. The ability to print real, 3D objects from a desktop device is a powerful new force in the way companies deliver products to customers and inventors bring their designs to life. Now, a team of bioengineers and physicians have developed a way to create a real-live human ear with a 3D printer. This ear not only resembles an actual human ear, it’s printed...

ROSEMONT, Ill., Jan. 28, 2013 /PRNewswire-USNewswire/ -- Osteoarthritis is a condition affecting millions of adults. The break-down of cartilage in the joints can be painful and debilitating. It is widely accepted that overweight individuals are at higher risk for developing osteoarthritis. The assumption has been that this was due to the higher amount of force placed on the joints which then contributed to the breakdown of tissue. (Logo:...

ROSEMONT, Ill., Jan. 25, 2013 /PRNewswire-USNewswire/ -- Osteoarthritis is a very common joint disorder. Due to age and normal wear and tear on the joints, the cartilage that protects the joint begins to break down, causing the bone to rub together which leads to pain and swelling in the joints. There is no cure for osteoarthritis, and up until now, many patients feel that surgery is their only option to manage the symptoms. (Logo:...
