Squeaky hips make media, medical noise
What’s behind those squeaking hips? “You didn’t put one of those squeaking hips in me, did you, doc?” “My hip made a funny sound last week, and my husband read in the paper that there’s been a recall. Am I going to have to have my new hip taken out?” Orthopaedic surgeons have been answering these questions ever since The New York Times published “That Must Be Bob. I Hear His New Hip Squeaking” this past May.

Reframing the debate on computer-navigated TKA
AICKH symposium examines new uses for computer-assisted navigation Using computer-assisted (CA) navigation in total knee arthroplasty (TKA) has become a hotly debated issue in the United States—effectively dividing the orthopaedic community into two “camps,” according to S. David Stulberg, MD, in his presentation of “Navigation TKA: State of the art and rationale” at the Advanced Imaging and Computer Assisted Surgery of the Knee and Hip (AICKH) symposium, held in March 2008.

Improving quality of care—one guideline at a time
A year’s effort pays off for patients and practitioners First identified more than 150 years ago, carpal tunnel syndrome (CTS) is one of the most commonly diagnosed and treated entrapment neuropathies. CTS is estimated to affect up to 10 percent of the entire population. With the variety of tests and treatment options used for this condition, it’s no wonder that developing evidence-based clinical practice guidelines (CPGs) for CTS was high on the AAOS agenda.

AAOS Clinical Guidelines on the Treatment of Carpal Tunnel Syndrome
Summary of Recommendations See the online version of the guidelines, available at www.aaos.org/guidelines, for a complete description of how the quality of evidence is rated and the recommendations are graded. Recommendation 1 A course of nonoperative treatment is an option in patients diagnosed with carpal tunnel syndrome (CTS). Early surgery is an option when there is clinical evidence of median nerve denervation or the patient elects to proceed directly to surgical treatment.

Can TAA be as successful as THA and TKA?
New designs, improved techniques raising TAA’s profile When total ankle arthroplasty (TAA) was first introduced in the 1970s, implants had good short-term results; long-term data, however, showed severe problems such as osteolysis, component loosening, impingement, infection, and soft-tissue breakdown.

Pappas, MD, of Strand Orthopaedic Consultants, LLC, in Myrtle Beach, S.C. Dr.

PED use: Legal, natural, and deadly
Doping, athletes, and how orthopaedic surgeons can help The use of performance-enhancing drugs (PEDs) among young athletes as well as among aging “baby boomers” has become widespread, according to Michael J. Stuart, MD, a participant in the American Orthopaedic Society for Sports Medicine (AOSSM) symposium on “Anti-Doping: Where do we go from here?” “This is not a new problem but it is certainly growing,” said Dr. Stuart.

MRSA: From the hospital and into the community
A more virulent form of these bacteria challenges the orthopaedic community The death of Ricky Lannetti, a senior at Lycoming College and a wide receiver on the football team, in 2003 due to community-acquired methicillin resistant Staphylococcus aureus (CA-MRSA) marked a turning point in awareness about the disease. “In the 1980s, we started hearing about ‘community-acquired MRSA,’” said Kathleen Weber, MD, MS, at the annual meeting of the American Orthopaedic Society of Sports Medicine.
