Low Early and Late Dislocation Rates with 36- and 40-mm Heads in Patients at High Risk for Dislocation

Paul F. Lachiewicz MD, Elizabeth S. Soileau BSN

Large (36- and 40-mm) femoral heads with highly crosslinked polyethylene liners were introduced to reduce the risk of dislocation after primary total hip arthroplasty (THA), but it is unclear whether the risk is reduced and whether there is osteolysis or liner fracture.

Does CT-Based Navigation Improve the Long-Term Survival in Ceramic-on-Ceramic THA?

Nobuhiko Sugano MD, PhD, Masaki Takao MD, PhD, Takashi Sakai MD, PhD, Takashi Nishii MD, PhD, Hidenobu Miki MD, PhD

Although navigated THA provides improved precision in implant positioning and alignment, it is unclear whether these translate into long-term implant survival.

Intraarticular Abnormalities in Residual Perthes and Perthes-like Hip Deformities

James R. Ross MD, Jeffrey J. Nepple MD, Geneva Baca, Perry L. Schoenecker MD, John C. Clohisy MD

Residual Perthes and Perthes-like hip deformities are complex and may encompass proximal femoral deformity, secondary acetabular dysplasia, and associated intraarticular abnormalities. These intraarticular abnormalities have not been well characterized but may influence surgical technique and treatment outcomes.

Acetabular Tilt Correlates with Acetabular Version and Coverage in Hip Dysplasia

Masanori Fujii MD, PhD, Yasuharu Nakashima MD, PhD, Taishi Sato MD, Mio Akiyama MD, Yukihide Iwamoto MD, PhD

The rotational position of the acetabulum to the pelvis (acetabular tilt) may influence acetabular version and coverage of the femoral head. To date, the pathologic significance of acetabular tilt in hip dysplasia is unknown.

Alumina Heads Minimize Wear and Femoral Osteolysis Progression After Isolated Simple Acetabular Revision

Philippe Hernigou MD, Nicolas Dupuy MD, Olivier Pidet MD, Yashuhiro Homma MD, Charles Henri Flouzat Lachaniette MD

Patients with THA requiring cup revision for acetabular osteolysis may have a stable stem component without loosening. However, it is unclear whether isolated cup revision halts femoral osteolysis progression.

Does Impact Sport Activity Influence Total Hip Arthroplasty Durability?

Matthieu Ollivier MD, Solenne Frey MD, Sebastien Parratte MD, PhD, Xavier Flecher MD, PhD, Jean-Noël Argenson MD

Return to sport is a key patient demand after hip arthroplasty and some patients are even involved in high-impact sports. Although polyethylene wear is related to the number of cycles and the importance of the load, it is unclear whether high-impact sport per se influences THA durability.

Is Administratively Coded Comorbidity and Complication Data in Total Joint Arthroplasty Valid?

Kevin J. Bozic MD, MBA, Ravi K. Bashyal MD, Shawn G. Anthony MD, MBA, Vanessa Chiu MPH, Brandon Shulman BS, Harry E. Rubash MD

Administrative claims data are increasingly being used in public reporting of provider performance and health services research. However, the concordance between administrative claims data and the clinical record in lower extremity total joint arthroplasty (TJA) is unknown.

Socket Position Determines Hip Resurfacing 10-Year Survivorship

Harlan C. Amstutz MD, Michel J. Duff MA, Alicia J. Johnson BA

Modern metal-on-metal hip resurfacing arthroplasty designs have been used for over a decade. Risk factors for short-term failure include small component size, large femoral head defects, low body mass index, older age, high level of sporting activity, and component design, and it is established there is a surgeon learning curve. Owing to failures with early surgical techniques, we developed a second-generation technique to address those failures. However, it is unclear whether the techniques affected the long-term risk factors.

High Survivorship of Cemented Sockets with Roof Graft for Severe Acetabular Dysplasia

Vincent J. J. F. Busch MD, Nicholas D. Clement MRCS, Ed, Philipp F. J. Mayer, Steffen J. Breusch FRCSEd, Colin R. Howie FRCSEd

Socket fixation in patients with acetabular dysplasia can be technically demanding but the use of structural grafts can help to reconstruct the original center of hip rotation. Because reported survival rates differ, construct survival seems to depend on the technique of graft preparation and fixation.

Joint-preserving Surgery Improves Pain, Range of Motion, and Abductor Strength After Legg-Calvé-Perthes Disease

Christoph Emanuel Albers MD, Simon Damian Steppacher MD, Reinhold Ganz MD, Klaus Arno Siebenrock MD, Moritz Tannast MD

Patients after Legg-Calvé-Perthes disease (LCPD) often develop pain, impaired ROM, abductor weakness, and progression of osteoarthritis (OA) in early adulthood. Based on intraoperative observations during surgical hip dislocation, we established an algorithm for more detailed characterization of the underlying pathomorphologies with a proposed joint-preserving surgical treatment.
