Do Monoblock Cups Improve Survivorship, Decrease Wear, or Reduce Osteolysis in Uncemented Total Hip Arthroplasty?

Jelle J. Halma MD, H. Charles Vogely MD, PhD, Wouter J. Dhert MD, PhD, Steven M. Gaalen MD, PhD, Arthur Gast MD, PhD

Monoblock acetabular components used in uncemented total hip arthroplasty (THA) have certain mechanical characteristics that potentially reduce acetabular osteolysis and polyethylene wear. However, the degree to which they achieve this goal is not well documented.

Is Intraarticular Pathology Common in Patients With Hip Dysplasia Undergoing Periacetabular Osteotomy?

Benjamin G. Domb MD, Justin M. Lareau MD, Hasan Baydoun MD, Itamar Botser MD, Michael B. Millis MD, Yi-Meng Yen MD, PhD

Periacetabular osteotomy (PAO) enables correction of bony acetabular deficiency in the setting of hip dysplasia. Patients with insufficient acetabular coverage often have intraarticular pathology, but the degree of this pathology has been incompletely characterized. We have used arthroscopy as an adjunct to PAO to further delineate intraarticular pathology in patients with hip dysplasia with mechanical symptoms.

Periprosthetic Fractures Around a Cementless Hydroxyapatite-coated Implant: A New Fracture Pattern Is Described

William N. Capello MD, James A. D’Antonio MD, Marybeth Naughton BS

Periprosthetic fractures can occur both intraoperatively and postoperatively with implantation of cementless tapered stems.

Muscle Strength and Functional Recovery During the First Year After THA

Dana L. Judd PT, DPT, Douglas A. Dennis MD, Abbey C. Thomas PhD, ATC, Pamela Wolfe MS, Michael R. Dayton MD, Jennifer E. Stevens-Lapsley PT, PhD

Patients undergoing total hip arthroplasty (THA) often are satisfied with the decrease in pain and improvement in function they achieve after surgery. Even so, strength and functional performance deficits persist after recovery, but these remain poorly characterized; knowledge about any ongoing strength or functional deficits may allow therapists to design rehabilitation programs to optimize recovery after THA.

Aspirin: An Alternative for Pulmonary Embolism Prophylaxis After Arthroplasty?

Ibrahim J. Raphael MD, Eric H. Tischler BA, Ronald Huang MD, Richard H. Rothman MD, PhD, William J. Hozack MD, Javad Parvizi MD, FRCS

The most effective agent for prophylaxis against venous thromboembolic disease after total joint arthroplasty (TJA) remains unknown. The paucity of literature comparing different methods of pulmonary embolism (PE) prophylaxis and fear of litigation make it difficult for surgeons to abandon the use of aggressive chemical prophylaxis.

Adverse Local Tissue Reaction Associated With a Modular Hip Hemiarthroplasty

Michael R. Whitehouse PhD, MSc, FRCS (Tr & Orth), Makoto Endo MD, PhD, Bassam A. Masri MD, FRCS(C)

The local and systemic effects of wear debris and corrosion products remain a concern in arthroplasty and reaction to corrosion or wear products from modular junctions has been reported in primary and revision total joint arthroplasties. These effects have not been reported previously for unipolar hemiarthroplasties where there is no prosthetic bearing surface to contribute to the phenomenon. This may have implications for clinical surveillance and implant design.

Hip Dysplasia Is More Severe in Charcot-Marie-Tooth Disease Than in Developmental Dysplasia of the Hip

Eduardo N. Novais MD, Sara D. Bixby MD, John Rennick MSc, Patrick M. Carry BA, Young-Jo Kim MD, PhD, Michael B. Millis MD

Patients with Charcot-Marie-Tooth disease may develop hip dysplasia. Hip geometry in these patients has not been well described in the literature.

Causes and Frequency of Unplanned Hospital Readmission After Total Hip Arthroplasty

William W. Schairer MD, David C. Sing BS, Thomas P. Vail MD, Kevin J. Bozic MD, MBA

Total hip arthroplasty (THA) is a beneficial and cost-effective procedure for patients with osteoarthritis. Recent initiatives to improve hospital quality of care include assessing unplanned hospital readmission rates. Patients presenting for THA have different indications and medical comorbidities that may impact rates of readmission.

Local Alendronic Acid Elution Increases Net Periimplant Bone Formation: A Micro-CT Analysis

J. Dennis Bobyn PhD, Rebecca Thompson MEng, Letitia Lim MD, Jenny Ann Pura BSc, Kristian Bobyn BA, Michael Tanzer MD

Fixation of cementless orthopaedic implants is not always achieved, particularly in challenging scenarios such as revision surgery, trauma, and tumor reconstruction. An adjunct therapy for improving implant fixation would improve the reliability and durability of certain reconstructive procedures.

Taper Design Affects Failure of Large-head Metal-on-metal Total Hip Replacements

Nader A. Nassif MD, Danyal H. Nawabi MD, Kirsten Stoner MEng, Marcella Elpers BS, Timothy Wright PhD, Douglas E. Padgett MD

Large-head metal-on-metal (MoM) hip arthroplasties have demonstrated poor survival. Damage at the taper-trunnion junction is a contributing factor; however, the influence of junction design is not well understood.
