Ceramic-on-Ceramic Total Hip Arthroplasty: Incidence of Instability and Noise

David Schroder MD, Lindsey Bornstein BA, Mathias P. G. Bostrom MD, Bryan J. Nestor MD, Douglas E. Padgett MD, Geoffrey H. Westrich MD

Alternative bearing materials in THA have been developed to reduce the incidence of osteolysis. Alumina-on-alumina bearings exhibit extremely low wear rates in vitro, but concerns exist regarding component impingement with the potential for dislocation and the occurrence of noise.

Incidence of Postthrombotic Syndrome in Patients Undergoing Primary Total Hip Arthroplasty for Osteoarthritis

Steven J. Fitzgerald MD, Christopher M. McAndrew MD, Matthew J. Kraay MD, Victor M. Goldberg MD

Postthrombotic syndrome (PTS) is a chronic condition in the lower extremity that develops after deep vein thrombosis (DVT). The incidence of PTS after total hip arthroplasty (THA) is not well established.

Acetabular UHMWPE Survival and Wear Changes With Different Manufacturing Techniques

John B. Meding MD, E. Michael Keating MD, Kenneth E. Davis MS

Polyethylene wear may be affected by the type of polyethylene resin, manufacturing technique, degree of thermal stabilization, and sterilization technique.

Perivascular Lymphocytic Infiltration Is Not Limited to Metal-on-Metal Bearings

Vincent Y. Ng MD, Adolph V. Lombardi MD, Keith R. Berend MD, Michael D. Skeels DO, Joanne B. Adams BFA

Perivascular lymphocytic infiltration (PVLI) suggests an adaptive immune response. Metal hypersensitivity after THA is presumed associated with idiopathic pain and aseptic loosening, but its incidence and relationship to metallic wear leading to revision are unclear as are its presence and relevance in non-metal-on-metal arthroplasty.

High Complication Rate With Anterior Total Hip Arthroplasties on a Fracture Table

Brian A. Jewett MD, Dennis K. Collis MD

Recent attention in THA has focused on minimally invasive techniques and their short-term outcomes. Despite much debate over the outcomes and complications of the two-incision and the mini-lateral and mini-posterior approaches, complications arising from use of the anterior THA on a fracture table are not well documented.

Multilevel Measurement of Acetabular Version Using 3-D CT-generated Models: Implications for Hip Preservation Surgery

Aimee C. Perreira BS, John C. Hunter MD, Thaddeus Laird MD, Amir A. Jamali MD

Numerous structural deformities of the acetabulum are associated with hip osteoarthritis (OA). Acetabular retroversion has been implicated in the development of femoroacetabular impingement. However, it is unknown if retroversion occurs from isolated excessive bone in the superior acetabulum or a torsional phenomenon of the entire pelvic segment.

The Need for Total Hip Arthroplasty in Perthes Disease: A Long-term Study

Lonnie Froberg MD, Finn Christensen MD, Niels Wisbech Pedersen MD, Søren Overgaard MD

Legg-Calvé-Perthes disease (LCPD) was described a century ago. In previous long-term reports of patients with LCPD, nonoperative treatment varied considerably. The likelihood of hip osteoarthritis (OA) developing in patients with LCPD and possible need for THA are not well defined.

Large Acetabular Defects Can be Managed with Cementless Revision Components

E. Scott Paxton MD, James A. Keeney MD, William J. Maloney MD, John C. Clohisy MD

Optimal techniques for acetabular revision in the setting of major pelvic osteolysis have not been established. Bilobed components, structural grafts, and reinforcement cages have demonstrated 10–24% midterm failure rates. While cementless hemispherical components have been utilized to treat large acetabular defects, most reports have not focused specifically on patients with extensive deficiencies.

Modular Femoral Stems for Revision Total Hip Arthroplasty

Camilo Restrepo MD, Magdalena Mashadi MD, Javad Parvizi MD, FRCS, Matthew S. Austin MD, William J. Hozack MD

Modular femoral stems are one option for revision THA surgeons and allow offset restoration, leg length discrepancy correction, and stability independent of distal stem fixation. The complexity of revision THA usually leads surgeons to use multiple revision hip designs to address these issues.

What Factors Influence Long-term Survivorship After Hip Arthroscopy?

Joseph C. McCarthy MD, Bryan T. Jarrett BS, Olumide Ojeifo BS, Jo Ann Lee MS, Charles R. Bragdon PhD

Hip arthroscopy is an evolving procedure. One small study suggested that a low modified Harris hip score and arthritis at the time of surgery were predictors of poor prognosis.
