Do Retrieval Analysis and Blood Metal Measurements Contribute to Our Understanding of Adverse Local Tissue Reactions?

Patricia A. Campbell PhD, Michael S. Kung BA, Andrew R. Hsu MD, Joshua J. Jacobs MD

Metal-on-metal (MoM) total hip arthroplasties (THAs) and the head-neck and neck-body junctions in modular THA are associated with a variety of local and systemic reactions to their related wear and corrosion products. Although laboratory testing is available, the relationship between laboratory values—including serum metal ion levels—and adverse local tissue reactions (ALTRs) remains controversial and incompletely characterized.

Do Patients With Insulin-dependent and Noninsulin-dependent Diabetes Have Different Risks for Complications After Arthroplasty?

Francis Lovecchio BA, Matthew Beal MD, Mary Kwasny ScD, David Manning MD

Patients with diabetes are known to be at greater risk for complications after arthroplasty than are patients without diabetes. However, we do not know whether there are important differences in the risk of perioperative complications between patients with diabetes who are insulin-dependent (Type 1 or 2) and those who are not insulin-dependent.

Are Harris Hip Scores and Gait Mechanics Related Before and After THA?

Omar A. Behery MPH, Kharma C. Foucher MD, PhD

Discordance between subjective and objective functional measures hinders the development of new ways to improve THA outcomes.

Systematic Review of Literature of Cemented Femoral Components: What Is the Durability at Minimum 20 Years Followup?

Nicholas A. Bedard MD, John J. Callaghan MD, Michael D. Stefl MD, Steve S. Liu MD

Cemented femoral total hip arthroplasty may be one of the most successful surgical interventions of all time. However, although results are very encouraging over the early to mid-term followup, relatively few studies have analyzed the durability of these implants beyond 20 years followup. To evaluate the performance of contemporary implants, it is important to understand how previous implants perform at 20 or more years of followup; one way to do this is to aggregate the available data in the form of a systematic review.

Can Wear Explain the Histological Variation Around Metal-on-metal Total Hips?

Edward Ebramzadeh PhD, Patricia Campbell PhD, Timothy L. Tan MD, Scott D. Nelson MD, Sophia N. Sangiorgio PhD

There is a general perception that adverse local tissue reactions in metal-on-metal hip arthroplasties are caused by wear, but the degree to which this is the case remains controversial.

Metal Artifact Reduction Sequence MRI Abnormalities Occur in Metal-on-polyethylene Hips

Thomas K. Fehring MD, Keith Fehring MD, Susan M. Odum PhD

To determine the importance of MRI abnormalities in metal-on-metal (MoM) bearings, it is important to understand the baseline features of this diagnostic tool in conventional metal-on-polyethylene (MoP) bearings.

Continued Good Results With Modular Trabecular Metal Augments for Acetabular Defects in Hip Arthroplasty at 7 to 11 Years

Michael R. Whitehouse PhD, MSc(Orth Eng), FRCS(Tr&Orth), Bassam A. Masri MD, FRCS(C), Clive P. Duncan MD, MSc, Donald S. Garbuz MD, MHSc

Reconstruction of large acetabular defects remains a substantial challenge in hip arthroplasty. There remains a paucity of data on the long-term results of acetabular trabecular metal augments.

Highly Crosslinked Polyethylene Improves Wear But Not Surface Damage in Retrieved Acetabular Liners

Hee-Nee Pang MD, Douglas D. R. Naudie MD, Richard W. McCalden MD, Steven J. MacDonald MD, Matthew G. Teeter PhD

Highly crosslinked polyethylene (XLPE) is believed to demonstrate better wear resistance than conventional polyethylene (CPE) in total hip arthroplasty.

Does HIV Infection Increase the Risk of Perioperative Complications After THA? A Nationwide Database Study

Qais Naziri MD, Matthew R. Boylan BS, Kimona Issa MD, Lynne C. Jones PhD, Harpal S. Khanuja MD, Michael A. Mont MD

Recent studies have shown successful midterm outcomes after total hip arthroplasty (THA) in patients with human immunodeficiency virus (HIV). However, little data exist on the epidemiology, risk of perioperative complications, and length of stay in patients with HIV receiving THA.

Porous Metal Acetabular Components Have a Low Rate of Mechanical Failure in THA After Operatively Treated Acetabular Fracture

Brandon J. Yuan MD, David G. Lewallen MD, Arlen D. Hanssen MD

Total hip arthroplasty (THA) for the treatment of posttraumatic osteoarthritis (OA) after acetabular fracture has been associated with a high likelihood of aseptic loosening, instability, and infection. Porous metal components may help to address the issue of loosening, but there are few data on the use of porous metal acetabular components for posttraumatic OA after acetabular fracture.
