Complication Rates After Hip or Knee Arthroplasty in Morbidly Obese Patients

Richard J. Friedman MD, Susanne Hess MD, Scott D. Berkowitz MD, Martin Homering MSPH

Morbid obesity has been shown to be a risk factor for increased complications after THA and TKA; however, large studies that would determine the effect size are lacking.

Patients With Unstable Slipped Capital Femoral Epiphysis Have Antecedent Symptoms

Thomas G. McPartland MD, Wudbhav N. Sankar MD, Young-Jo Kim MD, PhD, Michael B. Millis MD

The characteristics of patients who sustain unstable slipped capital femoral epiphyses (SCFEs) are not well described compared to their counterparts who sustain stable SCFE. Although patients with unstable slips are usually identified owing to acute symptoms, it is unclear whether these patients have premonitory symptoms that could heighten the awareness of treating physicians to the possibility of an unstable slip and lead to timely diagnosis and treatment.

CT Pulmonary Angiography After Total Joint Arthroplasty: Overdiagnosis and Iatrogenic Harm?

Michele R. D’Apuzzo MD, Thomas C. Keller MD, Wendy M. Novicoff PhD, James A. Browne MD

CT pulmonary angiography (CTPA) has become widely adopted to detect pulmonary embolism (PE) after total joint arthroplasty (TJA). CTPA is a sensitive tool, which has the ability to detect emboli that may be clinically insignificant. This may lead to iatrogenic harm from overtreatment.

Long-term (20- to 25-year) Results of an Uncemented Tapered Titanium Femoral Component and Factors Affecting Survivorship

Marcus R. Streit MD, MSc, Moritz M. Innmann MD, Christian Merle MD, MSc, Thomas Bruckner PhD, Peter R. Aldinger MD, PhD, Tobias Gotterbarm MD

Uncemented femoral components in primary total hip arthroplasty (THA) are commonly used today, but few studies have evaluated their survival into the third decade.

High Prevalence of Adverse Reactions to Metal Debris in Small-headed ASR™ Hips

Aleksi Reito MD, Timo Puolakka MD, PhD, Petra Elo MD, PhD, Jorma Pajamäki MD, PhD, Antti Eskelinen MD, PhD

There has been increasing concern of metal-on-metal (MOM) hip replacements regarding adverse reactions to metal debris. Information regarding prevalence and risk factors for these adverse reactions is scarce.

Reliability and Validity of Measuring Acetabular Component Orientation by Plain Anteroposterior Radiographs

Ming Lu MD, Yi-Xin Zhou MD, PhD, Hui Du MD, Ji Zhang MD, Jian Liu MD

Inaccurate placement of an acetabular cup can cause impingement, dislocation, and accelerated wear. However, there is no universally agreed-on approach to measuring cup position using plain radiographs.

Why Do Hip Arthroscopy Procedures Fail?

Ljiljana Bogunovic MD, Meghan Gottlieb MSW, Gail Pashos BS, Geneva Baca BA, John C. Clohisy MD

Despite the successes of hip arthroscopy, clinical failures do occur, and identifying risk factors for failure may facilitate refinement of surgical indications and treatment. Knowledge regarding the reasons for treatment failures may also improve surgical decision making.

Total Hip Arthroplasty for the Sequelae of Legg-Calvé-Perthes Disease

Yaser M. K. Baghdadi MD, A. Noelle Larson MD, Anthony A. Stans MD, Tad M. Mabry MD

The durability and risks associated with total hip arthroplasty (THA) for patients with a history of Legg-Calvé-Perthes disease (LCPD) are not well known.

Results of Treatment of Femoroacetabular Impingement in Adolescents with a Surgical Hip Dislocation Approach

Ernest L. Sink MD, Peter D. Fabricant MD, Zhaoxing Pan PhD, Michael R. Dayton MD, Eduardo Novais MD

The literature contains few studies of open treatment with an open surgical hip dislocation approach for treatment of femoroacetabular impingement (FAI) in adolescents. The average age and associated disorders in adolescents with FAI reveal a critical need to study younger patients whose hip disorder has not had time to progress.

Reliability of Overcoverage Parameters With Varying Morphologic Pincer Features: Comparison of EOS® and Radiography

Shafagh Monazzam MD, Mandar Agashe MD, Harish S. Hosalkar MD

Multiple radiographic parameters used for diagnosis and quantification of morphologic pincer features have emerged, but the degree to which pelvic tilt or rotation affects conventional radiography and EOSis unknown.
