Kaplan-Meier Survival Analysis Overestimates the Risk of Revision Arthroplasty: A Meta-analysis

Sarah Lacny MSc, Todd Wilson BSc, Fiona Clement PhD, Derek J. Roberts MD, Peter D. Faris PhD, William A. Ghali MD, MPH, Deborah A. Marshall PhD

Although Kaplan-Meier survival analysis is commonly used to estimate the cumulative incidence of revision after joint arthroplasty, it theoretically overestimates the risk of revision in the presence of competing risks (such as death). Because the magnitude of overestimation is not well documented, the potential associated impact on clinical and policy decision-making remains unknown.

Anterior and Anterolateral Approaches for THA Are Associated With Lower Dislocation Risk Without Higher Revision Risk

Dhiren Sheth MD, Guy Cafri PhD, Maria C. S. Inacio PhD, Elizabeth W. Paxton MA, Robert S. Namba MD

Lack of consensus continues regarding the benefit of anteriorly based surgical approaches for primary total hip arthroplasty (THA). The purpose of this study was to evaluate the risk of aseptic revision, septic revision, and dislocations for various approaches used in primary THAs from a community-based healthcare organization.

Do Complication Rates Differ by Gender After Metal-on-metal Hip Resurfacing Arthroplasty? A Systematic Review

Bryan D. Haughom MD, Brandon J. Erickson MD, Michael D. Hellman MD, Joshua J. Jacobs MD

Although metal-on-metal (MoM) bearing surfaces provide low rates of volumetric wear and increased stability, evidence suggests that certain MoM hip arthroplasties have high rates of complication and failure. Some evidence indicates that women have higher rates of failure compared with men; however, the orthopaedic literature as a whole has poorly reported such complications stratified by gender.

Femoroacetabular Impingement: Prevalent and Often Asymptomatic in Older Men: The Osteoporotic Fractures in Men Study

Lorenzo Nardo MD, Neeta Parimi MS, Felix Liu MS, Sonia Lee MD, Pia M. Jungmann MD, Michael C. Nevitt PhD, Thomas M. Link MD, PhD, Nancy E. Lane MD

The epidemiology of femoroacetabular impingement (FAI) is important but incompletely understood, because most reports arise from symptomatic populations. Investigating the prevalence of FAI in a community-based cohort could help us better understand its epidemiology and in particular the degree to which it might or might not be associated with hip pain.

What Host Factors Affect Aseptic Loosening After THA and TKA?

Jeffrey J. Cherian DO, Julio J. Jauregui MD, Samik Banerjee MD, Todd Pierce MD, Michael A. Mont MD

Aseptic loosening is the most common cause for revisions after lower-extremity total joint arthroplasties, however studies differ regarding the degree to which host factors influence loosening.

What Is the Rerevision Rate After Revising a Hip Resurfacing Arthroplasty? Analysis From the AOANJRR

James Min-Leong Wong MBBS, FRCS, Yen-Liang Liu M App Stats, Stephen Graves MBBS, Richard Steiger MBBS, FRACS, FA OrthoA

More than 15,000 primary hip resurfacing arthroplasties have been recorded by the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) with 884 primary procedures requiring revision for reasons other than infection, a cumulative percent revision rate at 12 years of 11%. However, few studies have reported the survivorship of these revision procedures.

Time-driven Activity-based Costing More Accurately Reflects Costs in Arthroplasty Surgery

Sina Akhavan BA, Lorrayne Ward MBA, MPP, Kevin J. Bozic MD, MBA

Cost estimates derived from traditional hospital cost accounting systems have inherent limitations that restrict their usefulness for measuring process and quality improvement. Newer approaches such as time-driven activity-based costing (TDABC) may offer more precise estimates of true cost, but to our knowledge, the differences between this TDABC and more traditional approaches have not been explored systematically in arthroplasty surgery.

Promising Mid-term Results With a Cup-cage Construct for Large Acetabular Defects and Pelvic Discontinuity

Tomas Amenabar MD, Wael A. Rahman MD, Bandar M. Hetaimish MD, Paul R. Kuzyk MD, Oleg A. Safir MD, Allan E. Gross MD

Restoring normal anatomy and achieving stable fixation of the acetabular component can be especially challenging when the surgeon must deal with severe acetabular defects and/or pelvic discontinuity. The cup-cage (CC) construct, where an ilioischial cage is cemented within a biologically fixed porous metal cup, has emerged as an excellent option to treat such challenges.

Standard Comorbidity Measures Do Not Predict Patient-reported Outcomes 1 Year After Total Hip Arthroplasty

Meridith E. Greene BA, Ola Rolfson MD, PhD, Max Gordon MD, PhD, Göran Garellick MD, PhD, Szilard Nemes PhD

Comorbidities influence surgical outcomes and therefore need to be included in risk adjustment when predicting patient-reported outcomes. However, there is no consensus on how best to use the available data about comorbidities in registry-based predictive models.

Twenty Percent of Patients May Remain Colonized With Methicillin-resistant Staphylococcus aureus Despite a Decolonization Protocol in Patients Undergoing Elective Total Joint Arthroplasty

Michael D. Baratz MD, Ruth Hallmark BSN, Susan M. Odum PhD, Bryan D. Springer MD

is the most commonly isolated organism in periprosthetic joint infection (PJI). Resistant strains such as methicillin-resistant(MRSA) are on the rise, and many programs have instituted decolonization protocols. There are limited data on the success ofnasal decolonization programs and their impact on PJI.
