Use of Topical Tranexamic Acid Reduces Direct and Indirect Blood Loss and Transfusion Rates in Revision Total Hip Arthroplasty.

Background: In primary total hip arthroplasty (THA), evidence supports the use of tranexamic acid (TXA) as an effective strategy for reducing blood loss, but scant evidence supports its use in revision THA.

Questions/purposes: We aimed to evaluate whether the use of topical TXA in revision THA is associated with less blood loss and lower transfusion rates and to assess its safety, specifically as it relates to thromboembolic complications.

Methods: In this retrospective comparative study, two groups who underwent revision THA between 2005 and 2017 were defined: 98 patients who received 3 g of topical TXA (study group) and 475 patients who did not receive TXA (control group).

Use of Surgical Approach Is Not Associated With Instability After Primary Total Hip Arthroplasty: A Meta-analysis Comparing Direct Anterior and Posterolateral Approaches.

Introduction: Posterolateral approach (PA) has been historically associated with an increased risk of dislocation after primary total hip arthroplasty (THA), especially when compared with the direct anterior approach (DAA). However, current evidence is inconsistent regarding the risk of dislocation with either approach. The purpose of this study is to determine whether surgical approach influences joint stability.

Topical Tranexamic Acid in Revision Total Knee Arthroplasty Reduces Transfusion Rates and May Be Associated With Earlier Recovery.

Background: The use of tranexamic acid (TXA) has been proved to be effective in reducing blood loss and transfusion requirements after primary total knee arthroplasty (TKA). However, the evidence for its use in revision surgery is scant. We assessed the safety and efficacy of topical TXA in revision TKA.

Characterization of Re-admission and Emergency Department Visits Within 90 Days Following Lower-Extremity Arthroplasty.

Background: Acute care events including emergency department (ED) visits and unscheduled inpatient re-admissions following lower-extremity arthroplasty are not fully understood.

Question/purposes: The purpose of this study was to characterize acute care events occurring after discharge in patients who received a lower-extremity arthroplasty: the incidence, timing, and risk factors of inpatient admission and ED visits within 90 days of discharge.

Methods: The New York State Inpatient and Emergency Department Databases were used to identify patients who underwent elective total knee arthroplasty (TKA) or total hip arthroplasty (THA) from 2009 to 2013 (124,234 and 76,411 patients, respectively).

Screening for Infection Before Revision Hip Arthroplasty: A Meta-analysis of Likelihood Ratios of Erythrocyte Sedimentation Rate and Serum C-reactive Protein Levels.

Introduction: Diagnosing periprosthetic joint infection (PJI) before revision hip arthroplasty is critical to ensure effective treatment of patients undergoing surgery for reasons other than infection. The main objective of our study is to determine whether the erythrocyte sedimentation rate (ESR) and the serum C-reactive protein (CRP) level are sufficient to use for testing to rule out infection in patients undergoing revision hip surgery.

Methods: We performed a systematic review of the literature in the MEDLINE, Ovid, and Embase databases.

A case of rapidly destructive osteoarthritis of the hip with onset of less than six weeks.

Introduction: Rapidly destructive osteoarthritis is characterized by a severe destruction of the hip joint developing over short periods of time. However, to date, there is no agreement on the biological process that triggers this condition. The aim of this report is to present a case of rapidly destructive osteoarthritis.

A retrospective study on the relationship between altered native acetabular angle and vertical implant malpositioning.

Purpose: Acetabular cup positioning in extreme angles of vertical position affects both stability and long-term survivorship of total hip arthroplasty. The purpose of this study is to determine whether native Sharp's angle is associated with an increased abduction angle of the acetabular component.

Methods: Consecutive patients who underwent primary total hip replacement between February 2012 and August 2015 were included.

Prenatal Ultrasound Diagnosis of Congenital Talipes Equinovarus in Bogota (Colombia) Between 2003 and 2012.

Introduction: Congenital Talipes Equinovarus (CTEV) or clubfoot is one of the most common congenital abnormalities(1,2). Early diagnosis by means of ultrasonography allows an opportune intervention and improves the deformity's correction prognosis.

Goal: To describe patients diagnosed with CTEV by means of prenatal sonographies between 2003 and 2012 in Bogotá (Colombia) at both the Institute de Ortopedia Infantil Roosevelt (IOIR) and one of the authors' private office.
