Preoperative Anemia in Total Joint Arthroplasty: Is It Associated with Periprosthetic Joint Infection?

Max Greenky BA, Kishor Gandhi MD, MPH, Luis Pulido MD, Camilo Restrepo MD, Javad Parvizi MD

Anemia is common in patients undergoing total joint arthroplasty (TJA). Numerous studies have associated anemia with increased risk of infection, length of hospital stay, and mortality in surgical populations. However, it is unclear whether and to what degree preoperative anemia in patients undergoing TJA influences postoperative periprosthetic joint infection (PJI) and mortality.

Culture-negative Periprosthetic Joint Infection Does Not Preclude Infection Control

Ronald Huang MD, Chi-Chien Hu MD, Bahar Adeli BS, Javad Mortazavi MD, Javad Parvizi MD

Periprosthetic joint infection (PJI) is a devastating complication after total joint arthroplasty. Lack of confirmation of an infecting organism poses a challenge with regard to the selection of an appropriate antibiotic agent and surgical treatment. It is unclear whether patients with negative cultures presumed to have infections achieve similar rates of infection-free survival as those with positive cultures.

Coordinating Retrieval and Register Studies Improves Postmarket Surveillance

Peter Ellison PhD, Geir Hallan MD, PhD, Paul Johan Høl PhD, Nils Roar Gjerdet DDS, PhD, Leif I. Havelin MD, PhD

The relative risk of revision of the Titanfemoral stem due to aseptic loosening increased after 2000; however, the reasons for this have not been established. A retrieval analysis was initiated with the aim of delineating the failure mechanism.

The Vascularized Fibular Graft in Precollapse Osteonecrosis: Is Long-term Hip Preservation Possible?

William C. Eward DVM, MD, Craig A. Rineer MD, James R. Urbaniak MD, Marc J. Richard MD, David S. Ruch MD

Osteonecrosis of the femoral head (ONFH) is a debilitating condition affecting primarily young patients. Free vascularized fibular grafting (FVFG) may provide a durable means to preserve the femoral head. When used in the precollapse stages of ONFH, this treatment may alter the course of disease.

A Dual-mobility Cup Reduces Risk of Dislocation in Isolated Acetabular Revisions

Roberto Civinini MD, Christian Carulli MD, Fabrizio Matassi MD, Lorenzo Nistri MD, Massimo Innocenti MD

Isolated acetabular revisions using standard cups are at risk of dislocation. The introduction of a nonconstrained dual-mobility cup was designed to improve prosthetic stability without increasing loosening rates, but it is unclear whether the risk of dislocation is reduced.

Do Concomitant Fractures With Hip Fractures Influence Complication Rate and Functional Outcome?

Benjamin Buecking MD, Christina Wack MD, Ludwig Oberkircher MD, Steffen Ruchholtz MD, Daphne Eschbach MD

Owing to the aging population, the incidence of hip fractures is increasing. While concomitant fractures are not uncommon, it is unclear how they influence subsequent function.

Is Routine Mid-term Total Hip Arthroplasty Surveillance Beneficial?

James A. Keeney MD, Bradley S. Ellison MD, William J. Maloney MD, John C. Clohisy MD

Routine followup of patients after primary or revision THA is commonly practiced and driven by concerns that delays in identifying early failure will result in more complicated or more costly surgical interventions. Although mid-term followup (4–10 years) has been performed to follow cohorts of patients, the benefit of observing individual patients regardless of symptoms has not been established.

Prevention of Nerve Injury After Periacetabular Osteotomy

Rafael J. Sierra MD, Paul Beaule MD, Ira Zaltz MD, Michael B. Millis MD, John C. Clohisy MD, Robert T. Trousdale MD

The Bernese periacetabular osteotomy (PAO) is the preferred pelvic osteotomy in many centers treating symptomatic acetabular dysplasia in the young adult. Major nerve injury has been reported as a complication that can occur with this complex procedure, but the incidence and circumstances associated with such injury are not well known.
