Complications of Total Hip Arthroplasty: Standardized List, Definitions, and Stratification Developed by The Hip Society

William L. Healy MD, Richard Iorio MD, Andrew J. Clair MD, Vincent D. Pellegrini MD, Craig J. Della Valle MD, Keith R. Berend MD

Reporting of complications after total hip arthroplasty (THA) is not standardized, and it is done inconsistently across various studies on the topic. Advantages of standardizing complications include improved patient safety and outcomes and better reporting in comparative studies.

Intraoperative Synovial C-reactive Protein Is as Useful as Frozen Section to Detect Periprosthetic Hip Infection

Martin A. Buttaro MD, Gabriel Martorell MD, Mauricio Quinteros MD, Fernando Comba MD, Gerardo Zanotti MD, Francisco Piccaluga MD

Synovial quantification of C-reactive protein (SCRP) has been recently published with high sensitivity and specificity in the diagnosis of periprosthetic joint infection. However, to our knowledge, no studies have compared the use of this test with intraoperative frozen section, which is considered by many to be the best intraoperative test now available.

Does Tranexamic Acid Reduce Blood Loss and Transfusion Requirements Associated With the Periacetabular Osteotomy?

Scott A. Wingerter MD, Angela D. Keith MS, Perry L. Schoenecker MD, Geneva R. Baca BA, John C. Clohisy MD

Tranexamic acid (TXA) has shown safety and efficacy in reducing blood loss associated with various surgical procedures. However, to our knowledge there are no studies evaluating the effect of TXA on blood loss and transfusion requirements associated with periacetabular osteotomy (PAO).

Acetate Templating on Digital Images Is More Accurate Than Computer-based Templating for Total Hip Arthroplasty

Robert Petretta BASc, MD, Jason Strelzow BSc, MD, Nicholas E. Ohly MSc, FRCSEd, Peter Misur MD, Bassam A. Masri MD

Templating is an important aspect of preoperative planning for total hip arthroplasty and can help determine the size and positioning of the prosthesis. Historically, templating has been performed using acetate templates over printed radiographs. As a result of the increasing use of digital imaging, surgeons now either obtain additional printed radiographs solely for templating purposes or use specialized digital templating software, both of which carry additional cost.

Wear and Osteolysis of Highly Crosslinked Polyethylene at 10 to 14 Years: The Effect of Femoral Head Size

Paul F. Lachiewicz MD, Elizabeth S. Soileau BSN, John M. Martell MD

Highly crosslinked polyethylene (XLPE) was introduced to decrease periprosthetic osteolysis related to polyethylene wear, a major reason for revision of total hip arthroplasty. However, there are few reports of wear and osteolysis at 10 years postoperatively.

Satisfying Outcomes Scores and Survivorship Achieved With Impaction Grafting for Revision THA in Young Patients

Martijn A. J. Stroet MD, Wim H. C. Rijnen MD, PhD, Jean W. M. Gardeniers MD, PhD, Albert Kampen MD, PhD, B. Willem Schreurs MD, PhD

The increasing number of total hip arthroplasties (THAs) performed in younger patients will inevitably generate larger numbers of revision procedures for this specific group of patients. Unfortunately, no satisfying revision method with acceptable survivorship 10 years after revision has been described for these patients so far.

Are There Modifiable Risk Factors for Hospital Readmission After Total Hip Arthroplasty in a US Healthcare System?

Elizabeth W. Paxton MA, Maria C. S. Inacio PhD, Jasvinder A. Singh MD, MPH, Rebecca Love MPH, RN, Stefano A. Bini MD, Robert S. Namba MD

Although total hip arthroplasty (THA) is a successful procedure, 4% to 11% of patients who undergo THA are readmitted to the hospital. Prior studies have reported rates and risk factors of THA readmission but have been limited to single-center samples, administrative claims data, or Medicare patients. As a result, hospital readmission risk factors for a large proportion of patients undergoing THA are not fully understood.

Cartilage Thickness and Cyst Volume Are Unchanged 10 Years After Periacetabular Osteotomy in Patients Without Hip Symptoms

Inger Mechlenburg PhD, Jens Randel Nyengaard DMSc, John Gelineck MD, Kjeld Soballe DMSc

Periacetabular osteotomy (PAO) may affect cartilage thickness and cyst volume in patients with hip dysplasia. However, as no studies randomizing patients to either PAO or conservative treatment have been performed, to our knowledge, it is unknown if PAO directly affects the development or progression of osteoarthritis in patients with hip dysplasia.

Association of Bisphosphonate Use and Risk of Revision After THA: Outcomes From a US Total Joint Replacement Registry

Monti Khatod MD, Maria C. S. Inacio PhD, Richard M. Dell MD, Stefano A. Bini MD, Elizabeth W. Paxton MA, Robert S. Namba MD

Total hip arthroplasty (THA) is often performed in patients who are older and may take bisphosphonates to treat a variety of conditions, most commonly osteoporosis. However, the clinical effects of bisphosphonate use on patients who have undergone THA are not well described.

What Can We Learn From 20-year Followup Studies of Hip Replacement?

Christopher T. Martin MD, John J. Callaghan MD, Yubo Gao PhD, Andrew J. Pugely MD, Steve S. Liu MD, Lucian C. Warth MD, Devon D. Goetz MD

A patient who dies during the followup period of a study about total hip arthroplasty (THA) cannot subsequently undergo a revision. The presence of competing events (such as deaths, in a study on implant durability) violates an assumption of the commonly used Kaplan-Meier (KM) survivorship approach. In that setting, KM-based estimates of revision frequencies will be high relative to alternative approaches that account for competing events such as cumulative incidence methods. However, the degree to which this difference is clinically relevant, and the degree to which it affects different ages of patient cohorts, has been poorly characterized in orthopaedic clinical research.
