Pelvic discontinuity is a challenging complication encountered during revision total hip arthroplasty. Pelvic discontinuity is defined as a separation of the ilium superiorly from the ischiopubic segment inferiorly and is typically a chronic condition in failed total hip arthroplasties in the setting of bone loss. After a history and a physical examination have been completed and infection has been ruled out, appropriate imaging must be obtained, including plain hip radiographs, oblique Judet radiographs, and often a CT scan...

Total joint arthroplasty (TJA) of the hip or knee (THA, TKA) has become an increasingly common procedure. While TJA is a successful treatment for individuals experiencing degenerative joint diseases, it is well known that one of the most common perioperative complications of TJA is deep venous thrombosis (DVT). To profile tissue factor (TF), microparticle-tissue factor (MP-TF), thrombin-activatable fibrinolysis inhibitor (TAFI), and fibrinogen levels in patients undergoing TJA to determine potential preexisting Hemostatic dysregulation...

BACKGROUND: Functional recovery monitoring after total hip arthroplasty (THA) and total knee arthroplasty (TKA) is often limited to surgeon-based assessment and patient self-reporting rather than objective measures. However, traditional outcomes may not reliably gauge return of function. The goal of this study was to evaluate and compare an objective measure of postoperative recovery, daily step-count, with patient self-reported outcomes. METHODS: Prospectively, 589 patients used a mobile step-tracking application to record daily steps...

BACKGROUND: Readmission among Medicare recipients is a leading driver of healthcare expenditure. To date, most predictive tools are too coarse for direct clinical application. Our objective in this study is to determine if a pre-existing tool to identify patients at increased risk for inpatient falls, the Hendrich Fall Risk Score, could be used to accurately identify Medicare patients at increased risk for readmission following arthroplasty, regardless of whether the readmission was due to a fall...

BACKGROUND: There are relatively few 20-year results of uncemented acetabular components, and most of these are modular designs. This study reports the 20-year results of a monoblock press-fit acetabular component. METHODS: A total of 122 total hip arthroplasties (111 patients) using the Morscher cup were reviewed at a mean of 19.7 years. The average age at implantation was 57.3 years (range, 36-74 years), and 81 (66%) were men. RESULTS: Twenty-two patients (25 hips) had died...

BACKGROUND: It is unknown to what extent diabetes mellitus modifies the long-term risk of aseptic loosening in total hip arthroplasty (THA) and total knee arthroplasty (TKA). We examined the association between diabetes mellitus, perioperative hyperglycemia, and the likelihood of revisions for aseptic loosening. METHODS: We studied 16,085 primary THA and TKA procedures performed at a large tertiary care hospital between 2002 and 2009. All blood glucose values around the time of surgery (within 1 week) were retrieved...

BACKGROUND: Periprosthetic joint infection (PJI) remains one of the most challenging and devastating modes of failure after total hip and knee arthroplasties. Despite the profound urgency and impact of PJI on an individual and societal basis, historically, there have not been standardized definitions of and diagnostic algorithms for infection after total joint arthroplasty. METHODS: In a recent symposium, the American Academy of Hip and Knee Surgeons put forth a standardized approach to the prevention, diagnosis, and management of the patient with a suspected PJI...

BACKGROUND: Tranexamic acid (TXA) has been associated with decreased blood loss and transfusion after total hip arthroplasty (THA) and total knee arthroplasty (TKA). The purpose of this study was to examine both transfusion utilization and the economic impact of a Process Improvement Project implementing TXA for THA and TKA. METHODS: After standardization of TXA administration in THA and TKA patients, retrospective data were compared from 12 consecutive months before (group A, n = 336 procedures) and after (group B, n = 436 procedures) project initiation...

BACKGROUND: Inclusion of patient satisfaction scores in setting reimbursements has been suggested by health care policy makers to contain cost and improve outcomes. The Short Form 36 Health Survey (SF-36) score provides a health-related quality of life (HRQoL) measure of arthroplasty outcome. Although previous work identified factors that influence this score for hip and knee arthroplasty patients, they did not focus on how a surgeon might use this information in a clinical setting. The present study examined whether relatively simple criteria might identify patients more likely to experience minimal HRQoL improvement...

BACKGROUND: Venous thromboembolism is one of the general complications following total hip arthroplasty, wherein various preventive treatments have been recommended. Several studies reported that venous thromboembolism incidence after total hip arthroplasty was similar in patients who were administered prophylaxis with a conventional mechanical procedure alone, and those who were administered pharmacological anticoagulation therapy. Therefore, the optimum methods of prophylaxis are still controversial...

BACKGROUND: Although antibiotic-loaded acrylic cement (ALAC) is used to prevent and treat periprosthetic hip infection, it is unknown how much antibiotic is deposited in the body in vivo, how high the serum concentration rises, or how long its effects last. The aim of this study was firstly to determine the amount of vancomycin (VCM) deposited as ALAC in the body, and secondly to assess the safety and drug elution profile of VCM in ALAC. METHODS: We administered VCM to prevent infection after total hip arthroplasty (THA) or to treat patients with methicillin-resistant Staphylococcus aureus...

BACKGROUND: Disparities in total joint arthroplasty (TJA) have largely been studied in single center studies and using administrative data. Our objective was to investigate differences in TJA outcomes in white men, black men, white women, and black women using a large international registry. METHODS: We used 2010-2013 data from the ACS-NSQIP to identify four groups of adults (white men, black men, white women, black women) who underwent primary total knee arthroplasty (TKA) or total hip arthroplasty (THA)...

BACKGROUND: Adverse local tissue reaction formation has been suggested to occur with the Modular Dual Mobility (MDM) acetabular design. Few reports in the literature have evaluated fretting and corrosion damage between the acetabular shell and modular metal inserts in this modular system. We evaluated a series of 18 retrieved cobalt chromium MDM inserts for evidence of fretting and corrosion. METHODS: We assessed the backsides of 18 MDM components for evidence of fretting and corrosion in polar and taper regions based on previously established methods...

BACKGROUND: Periprosthetic femur fractures after primary and revision total hip arthroplasty (THA) are one of the most common long-term reasons for reoperation after THA. Previous investigations have analyzed the incidence and risk factors of these fractures. No previous study, however, has analyzed a variation in periprosthetic femur fractures between meteorologic seasons. The aim of this study was to compare the incidence of periprosthetic femur fractures after primary and revision THAs depending on the meteorologic season...

INTRODUCTION: Little is known about pseudotumor frequency and risk factors for pseudotumor formation among different types of metal-on-metal (MoM) hip arthroplasties. A lower release of chromium and cobalt have been reported in MoM hip arthroplasties with a titanium sleeve compared to MoM designs without a titanium sleeve, but yet it is unknown whether a titanium sleeve reduces the pseudotumor frequency. We conducted a cross-sectional study to investigate: 1) pseudotumor frequency, 2) risk factors of pseudotumor formation 3) and correlations between pseudotumors, serum metal-ions, implant position, and clinical symptoms...

BACKGROUND: Total hip arthroplasty is the most widely used procedure to treat avascular necrosis (AVN) of the femoral head. Few studies have compared the outcomes of THA in femoral head AVN and primary hip osteoarthritis. Therefore we performed a case-control study to compare THA for femoral head AVN vs. primary hip osteoarthritis in terms of: (1) prosthesis survival, (2) complication rates, (3) functional outcomes and radiographic outcomes, (4) and to determine whether specific risk factors for THA failure exist in femoral head AVN...

A revision stem may be required after a femoral extended trochanteric osteotomy (ETO) is made during revision hip arthroplasty. The two main complications of straight cementless femoral stems are subsidence due to inadequate osteointegration and stress-shielding. We will describe an original revision method with ETO that uses a straight cementless stem. The goal of this method was to achieve the most extensive press-fit possible during stem implantation to improve the transmission of stresses to the bone and to prevent reduction in bone density...
