Despite extensive research regarding risk factors for adverse events after total joint arthroplasty (TJA), there are few publications describing the timing at which such adverse events occur.

Obesity Epidemic: Is Its Impact on Total Joint Arthroplasty Underestimated? An Analysis of National Trends

Obesity is a well-established risk factor for total joint arthroplasty (TJA) and a number of complications including prosthetic joint infection. The annual changes in the prevalence of obesity among primary, revision, and infected TJA has not been studied at a national level. Given the higher costs of complications of TJA, it is important to understand the association of obesity with the annual trends of revision and infected TJA.

What Orthopaedic Operating Room Surfaces Are Contaminated With Bioburden? A Study Using the ATP Bioluminescence Assay

Raveesh Daniel Richard MD, Thomas R. Bowen MD
3rd January 2017, Symposium: 2016 Musculoskeletal Infection Society Proceedings

Contaminated operating room surfaces can increase the risk of orthopaedic infections, particularly after procedures in which hardware implantation and instrumentation are used. The question arises as to how surgeons can measure surface cleanliness to detect increased levels of bioburden. This study aims to highlight the utility of adenosine triphosphate (ATP) bioluminescence technology as a novel technique in detecting the degree of contamination within the sterile operating room environment.

Phosphatidylcholine Coatings Deliver Local Antimicrobials and Reduce Infection in a Murine Model: A Preliminary Study

Michael A. Harris BSBE, Karen E. Beenken PhD, Mark S. Smeltzer PhD, Warren O. Haggard PhD, J. Amber Jennings PhD
3rd January 2017, Symposium: 2016 Musculoskeletal Infection Society Proceedings

Phosphatidylcholine coatings have been shown to elute antibiotics for several days. A recently developed biofilm inhibitor, cis-2-decenoic acid (C2DA), has been shown to exhibit synergistic activity with several common antibiotics. This study aims to evaluate the effectiveness of C2DA and amikacin dual drug delivery from a phosphatidylcholine coating.

Racial Disparities in Above-knee Amputations After TKA: A National Database Study

Jaiben George MBBS, Suparna M. Navale MS, MPH, Nicholas K. Schiltz PhD, Miguel Siccha MD, Alison K. Klika MS, Carlos A. Higuera MD
19th December 2016, Symposium: 2016 Musculoskeletal Infection Society Proceedings

Above-knee amputation (AKA) is a rare but devastating complication of TKA. Although racial disparities have been previously reported in the utilization of TKA, it is unclear whether disparities exist in the rates of AKA after TKA.

False-positive Cultures After Native Knee Aspiration: True or False

Jason M. Jennings MD, DPT, Douglas A. Dennis MD, Raymond H. Kim MD, Todd M. Miner MD, Charlie C. Yang MD, David C. McNabb MD
9th December 2016, Symposium: 2016 Musculoskeletal Infection Society Proceedings

Synovial fluid aspiration is a routine practice used by most orthopaedic surgeons to aid in the diagnosis of joint infection. In patients for whom there is a low pretest probability of infection, a positive culture—particularly if it is a broth-only culture—may be considered a contaminant, especially if the bacterial species are skin pathogens. To our knowledge no study has evaluated the incidence of contamination of aspirations from the native knee.

Perioperative Risk Adjustment for Total Shoulder Arthroplasty: Are Simple Clinically Driven Models Sufficient?

David N. Bernstein MA, Aakash Keswani BA, David Ring MD, PhD
30th November 2016, Symposium: Learning From Large-Scale Orthopaedic Databases

There is growing interest in value-based health care in the United States. Statistical analysis of large databases can inform us of the factors associated with and the probability of adverse events and unplanned readmissions that diminish quality and add expense. For example, increased operating time and high blood urea nitrogen (BUN) are associated with adverse events, whereas patients on antihypertensive medications were more likely to have an unplanned readmission. Many surgeons rely on their knowledge and intuition when assessing the risk of a procedure. Comparing clinically driven with statistically derived risk models of total shoulder arthroplasty (TSA) offers insight into potential gaps between common practice and evidence-based medicine.
