Scientist John Szivek uses stem cells to treat Arthritis

TUCSON (KGUN9-TV) –  More than 30 million Americans suffer from painful arthritis in their joints, Osteoarthritis.  The most common problem is knee pain caused by cartilage breaking down.  But some remarkable findings at the UA Arthritis Center could change the way doctors treat these patients.

Since our knees carry most of our body weight, it’s no surprise that the joints can wear out.  Too much wear-and-tear on the cartilage covering the bone can cause serious knee pain.  Right now, the only solution is replacing the entire joint with metal and plastic parts, even if the damage is just in one

Nanoscale films developed at MIT promote bone growth, creating a stronger seal between implants and patients’ own bone.

Every year, more than a million Americans receive an artificial hip or knee prosthesis. Such implants are designed to last many years, but in about 17 percent of patients who receive a total joint replacement, the implant eventually loosens and has to be replaced early, which can cause dangerous complications for elderly patients.

To help minimize these burdensome operations, a team of MIT chemical engineers has developed a new coating for implants that could
