Patients with PsA may benefit from new medications and surgeries

Medications or biologic agents that target T-cells, white blood cells involved in the body's immune system, appear to offer significant benefit to patients suffering from psoriatic arthritis (PsA), a type of arthritis that affects up to 48 percent of patients with the skin disease psoriasis, according to a new review article in the Journal of the American Academy of Orthopaedic Surgeons.

Coexisting comorbidities increase treatment costs for older adults with hip fractures

More than 250,000 hip fractures occur every year in the U.S., often resulting in hospitalization, surgery, nursing-home admission, long-term disability, and/or extended periods of rehabilitation. Independent existing medical conditions significantly increase the treatment cost and length of hospitalization for older adults who have sustained a hip fracture, according to a new study recently published in the Journal of Bone and Joint Surgery.

Stem cell like progenitor cells could be key to aging slowly: Study

In new research on mice, scientists have found that stem cells could help slow the aging process. This new research was conducted on mice that had been bred to have progeria, a disorder that causes premature aging. Mice with the condition typically live only 21 to 28 days instead of the usual two years.

Young stem/progenitor cells improve health and life of progeria mice

Mice bred to age too quickly seemed to have sipped from the fountain of youth after scientists at the University of Pittsburgh School of Medicine injected them with stem cell-like progenitor cells derived from the muscle of young, healthy animals.

Surprising finding about implants used in hip replacement surgery

A new study, bringing together an interdisciplinary team of physicians and engineers from the United States and Germany, made a surprising finding about implants used in hip replacement surgery: Graphite carbon is a key element in the lubricating layer that forms on metal-on-metal hip implants. The lubricant has more in common with the lubrication of a combustion engine than that of a natural joint.

Gottlieb surgeon's evaluations of top five winter sports

The first day of winter is Wednesday, December 21, and many states are bracing for a season of snow and ice. Broken bones from snowboarding and sledding top the list of common visits to the Emergency Department (ED) during the winter months. According to the Centers for Disease Control and Prevention, one-quarter of all emergency hospital visits are attributed to snowboarding accidents, and half of all cases were for broken bones and sprains.

Early aquatic therapy after TKA may improve quality of life

Despite increased use of total hip arthroplasty (THA) and total knee arthroplasty (TKA), there is a notable lack of consensus about optimal postoperative treatment. Aquatic therapy has been shown to have a beneficial effect, and it is typically begun two weeks after surgery, after the wound has healed.

Patients need less blood after surgery than is widely thought

Patients need less blood after surgery than is widely thought. A new study comparing two plans for giving blood transfusions following surgery showed no ill effects from postponing transfusion until patients develop signs of anemia or their hemoglobin concentration falls below 8 g/dL.

New knee replacement model increases likelihood of early revision surgery

Orthopaedic surgeons face a steep learning curve to get used to new prostheses, and the instruments and methods that go with them, before new total knee replacement procedures are as safe and effective as conventional methods. Patients who undergo the first 15 operations using a new device in a hospital are 48 percent more likely to need early revision surgery, than patients undergoing an operation to fit a prosthesis previously used in the hospital.

Study reveals no clear advantage of one implant type over another

More than 270,000 Americans get hip replacement surgeries every year -- a number that is projected to double in the next decade as the population ages. With various options for implants, including metal-on-polyethylene, metal-on-metal and ceramic-on-ceramic, there have been questions about which kind works best.
