Confusion Reigns in MoM Hip Implant Debacle (with video)
Although there is wide agreement that metal-on-metal hip implants have not performed as well as they should overall, consensus on managing patients who already have them remains elusive.
That was the essential take-away message from a series of research studies presented here at the American Academy of Orthopedic Surgeons' annual meeting this week. Seemingly, every talk contradicted the one preceding it. Medpage Today

Authors with financial conflicts reporting negative outcomes in major orthopaedic journals
In a new study presented today at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), researchers completed a systematic review of three major orthopaedic journals – the Journal of Bone and Joint Surgery (American and British editions) and the Journal of Arthroplasty (JOA) – for all articles related to metal-on-metal total hip replacement between October 1999 and May 2011. As a conflict of interest can increase the potential for research bias and study outcomes, the AAOS and major orthopaedic journals require all presenters and authors to disclose potential professional conflicts.

Delaying ACL reconstruction in kids may lead to higher rates of associated knee injuries
Kids treated more than 150 days after an Anterior Cruciate Ligament (ACL) injury have higher rates of other knee injuries, including medial meniscal tears, say researchers presenting at the American Orthopaedic Society for Sports Medicine's (AOSSM) Specialty Day in San Francisco, CA. Eurekalert!
PRP treatment aids healing of elbow injuries say researchers
As elbow injuries continue to rise, especially in pitchers, procedures to help treat and get players back in the game quickly have been difficult to come by. However, a newer treatment called platelet rich plasma (PRP) may pose hope, according to researchers presenting their findings at the American Orthopaedic Society for Sports Medicine's Specialty Day meeting in San Francisco.

Treatment for hip conditions should not rest solely on MRI scans
When it comes to treating people with hip pain, physicians should not replace clinical observation with the use of magnetic resonance images (MRI), according to research being presented today at the American Orthopaedic Society for Sports Medicine's (AOSSM) Specialty Day in San Francisco, CA.
"We performed MRI scans on a sample of volunteers without any hip pain, and discovered about 73% had abnormal findings," commented the study's lead author Bradley C. Register, MD, of the Steadman-Philippon Research Institute. Eurekalert!

Steroid injections prove effective in treatment of lumbar disc herniations
The use of epidural steroid injections may be a more efficient treatment option for lumbar disc herniations, according to research presented today at the American Orthopaedic Society for Sports Medicine's Specialty Day in San Francisco.
"Our study showed an 89% success rate in athletes returning to play after suffering an injury during practice or a game," commented lead author Aaron J. Krych, MD, from the Mayo Clinic's Department of Orthopaedic Surgery. "These injections are a safe initial therapy in athletes that do not have neurological deficits, allows them to participate effectively in physical therapy sooner, and can significantly reduce the time a player misses."

Arthritic knees, but not hips, have robust repair response
Researchers at Duke University Medical Center used new tools they developed to analyze knees and hips and discovered that osteoarthritic knee joints are in a constant state of repair, while hip joints are not.
"This suggests the knee has capacity for repair we didn't know about and the main treatment strategy probably would need to focus on turning off the breakdown of knee tissue," said Virginia Kraus, M.D., Ph.D., professor of Rheumatology and Immunology at Duke.
The findings, published in the Journal of Biological Chemistry on Friday, Feb. 10, suggest that for hips, however, turning off the degenerative process might not be enough. The hips would need a treatment to both turn off of the degenerative process as well as stimulate factors that could help to begin repair. Eurekalert!

Army studies: High recurrence of shoulder instability, better arthroscopic repair outcomes
Two studies on shoulder instability in a military population were presented today by U.S. Army sports medicine surgeons at the American Academy of Orthopaedic Surgeons' annual meeting. Findings in one study suggest patients with a self-reported history of shoulder instability are far more likely to experience future instability, while the second study outlined key factors associated with surgical failure and concluded that arthroscopic surgical intervention has better outcomes than an open shoulder repair.

Shorter hospital stay for knee replacement linked with greater revision, mortality risks
No previous research has quantified and compared the costs and outcomes between total knee replacement (TKR) patients who have differing lengths of hospital stay following surgery.
In new research presented today at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), investigators identified Medicare patients who had undergone TKR between 1997 and 2009. The patients were separated into the following groups: outpatient, 1-day inpatient, 2-day inpatient, 3- or 4-day inpatient (standard of care), and 5 plus day inpatient. Investigators reviewed outcomes for the patient groups including annual payments, mortality, readmission, revision and common complications. Eurekalert!

New method makes culture of complex tissue possible in any lab
Scientists at the University of California, San Diego have developed a new method for making scaffolds for culturing tissue in three-dimensional arrangements that mimic those in the body. This advance, published online in the journal Advanced Materials, allows the production of tissue culture scaffolds containing multiple structurally and chemically distinct layers using common laboratory reagents and materials.

AAOS focuses on disaster responders, both yesterday's and tomorrow's
When mass-casualty events occur, orthopaedic surgeons travel throughout the world to treat wounded patients in countries devastated by war, natural disaster and poverty. In 2010, 500 U.S. orthopaedic surgeons traveled to Haiti to help treat hundreds of thousands of victims following a catastrophic earthquake on that Caribbean island. And while the effort was generally successful in treating the broken bones, fractures and other orthopaedic injuries associated with earthquakes, not all of the volunteers were adequately prepared to work in a devastated country.

4.5 million Americans living with total knee replacement
New research presented at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) found that more than 4.5 million Americans are living with a total knee replacement (TKR), as the number of TKR surgeries has more than doubled over the past decade, with the sharpest rise among younger patients. Osteoarthritis continues to be the primary reason for TKR. Eurekalert!
Rothman at Jefferson researchers show benefits of local anesthesia after knee replacement surgery
Researchers at the Rothman Institute at Jefferson have shown that local anesthesia delivered through a catheter in the joint, intraarticularly, may be more beneficial than traditional opioids such as morphine and Oxycontin for pain management following total knee replacement surgery. Their research will be recognized with the Knee Society Award for the best work on a surgical technique at the American Academy of Orthopedic Surgeons annual meeting, February 7-11 in San Francisco.

Video-based home exercise can minimize osteoarthritis pain, improve mobility
The benefits of exercise in minimizing pain and improving mobility for individuals living with osteoarthritis has been well documented.
In a new study presented today at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), 107 individuals with diagnosed osteoarthritis in the knee were randomized to either a DVD-based exercise group, or a control group. The "DVD" group received a DVD-based exercise program, as well as verbal and hands-on exercise instructions, for the first four to eight weeks. The individuals in both groups were evaluated at three, six and 12 months. Eurekalert!

Anxiety trait linked to post-operative pain in men following total knee replacement
Increased pain following surgery has long been linked to anxiety and "catastrophizing," an extreme response to stress.
In a new study presented today at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), 97 patients – men and women – who were about to undergo minimally invasive total knee replacement (TKR) surgery, completed a brief survey to quantify their level of anxiety, as well as their typical level of anxiety and potential for catastrophizing. Pain data was then collected for seven days following surgery. Eurekalert!

BattleView Infrared Vascular Trans-illuminator Shows Off Veins When The Lights Are Out
Let’s just say that you’re a medic out there “in the field” in the middle of the night, with bad guys all over the surrounding hill tops, and they just shot one of your buddies. You managed to move the injured soldier to a safer location, and are attempting to setup an IV, but you certainly don’t want to turn on the flashlight with enemy snipers scanning every inch of the landscape.
That’s where the BattleView Infrared Vascular Trans-illuminator may be of help, as it shines infrared light through the body part where you’re trying to set the IV, illuminating the internal anatomy for your night vision goggles to see as bright as day. MedGadget

Post surgical phone support improves outcome following knee replacement
Poor emotional health and morbid obesity are associated with less functional gain following total knee replacement (TKR) surgery. In the new study, "Can Telephone Support During Post-TKR Rehabilitation Improve Post-op Function: A Randomized Controlled Trial," presented today at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), approximately 180 patients were categorized by gender, body mass index (BMI) and emotional health. Each patient randomly received either emotional telephone support by a trained behavioral specialist, or standard patient care. Telephone support included three phone calls before surgery, one in-person hospital visit, and eight weekly post-operative calls. Eurekalert!
