BACKGROUND: Patients with pincer-type femoroacetabular impingement are commonly treated with arthroscopic reduction of acetabular depth as measured by the lateral center-edge angle (LCEA). The optimal amount of rim reduction has not been established, although large resections may increase contact pressures through the hip. A recent publication demonstrated inferior surgical outcomes in patients with acetabular overcoverage as compared with normal acetabular coverage. Casual observation of our database suggested equivalent improvements, prompting a similar analysis...

Current literature suggests a correlation between preoperative coagulopathies and postsurgical adverse events (AEs). However, this correlation has not been specifically assessed in the total hip arthroplasty (THA) and the total knee arthroplasty (TKA) populations. Patients who underwent primary THA and TKA with coagulopathy data were identified from the 2011-2015 American College of Surgeons National Surgical Quality Improvement Program database. Coagulopathies studied were low platelets, high partial thromboplastin time (PTT), high international normalized ratio (INR), and other hematological conditions...

Patients with morbid obesity, defined as body mass index of greater than 40 kg/m2 , are being referred for weight loss and bariatric surgery before being accepted for a total knee arthroplasty (TKA). Previous studies have identified the risks associated with doing a TKA in an individual with an increased body mass index. We now present data identifying the same risks in individuals who have undergone bariatric surgery before submitting to TKA. Questions/Purposes: (1) Has the bariatric surgery improved the risk profile for the subsequent TKA? (2) Does the type of bariatric procedure matter? Method: A retrospective cohort study was conducted of patients who underwent bariatric surgery followed by TKA using Medicare hospital claims data...

BACKGROUND: Efforts to identify preoperative risk factors for primary total hip arthroplasty have amplified with its increasing incidence. The international normalized ratio (INR) is 1 measure that may influence postoperative outcomes. This study of a national database assessed whether there exists an association between preoperative INR and postoperative bleeding and mortality among patients who underwent primary total hip arthroplasty. METHODS: We retrospectively analyzed 17,567 adult patients who underwent primary total hip arthroplasty in the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) between 2005 and 2016...

BACKGROUND: Aspirin has been shown to be a safe and cost-effective thromboprophylaxis agent with equivalent preventive efficacy to warfarin and fewer side-effects. However, animal studies have suggested delayed bone healing with aspirin and other inhibitors of prostaglandin synthesis. The impact of aspirin on aseptic loosening following cementless total hip arthroplasty (THA) has yet to be explored. Our aim was to determine if patients receiving aspirin for thromboprophylaxis had higher rates of aseptic loosening vs patients receiving warfarin after THA...

BACKGROUND: Consensus guidelines recommend use of the international normalized ratio (INR) to predict the risk of perioperative bleeding in orthopaedic surgery. However, current recommendations for targeting an INR of <1.5 are based on studies across all surgical disciplines. This study examined the impact of the INR on perioperative bleeding, mortality, postoperative infections, length of hospital stay (LOS), and readmissions following primary total knee arthroplasty (TKA). METHODS: We retrospectively reviewed the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database for adult patients who underwent primary TKA from 2010 to 2016...

BACKGROUND: Although morbid obesity is considered a modifiable risk factor for periprosthetic joint infection (PJI), there is no consensus regarding an appropriate threshold for body mass index (BMI) above which a high risk for infection may outweigh the benefits of surgery. QUESTIONS/PURPOSES: (1) Is there a BMI cutoff threshold that is associated with increased risk for PJI? (2) Is the risk of PJI increased in higher obesity classes? METHODS: A retrospective study was conducted of all primary THAs and TKAs performed at one institution between 2006 and 2015...

BACKGROUND: Tranexamic acid (TXA) has been routinely delivered in multisegmental spinal decompression and bone graft fusion surgeries with satisfactory outcomes in minimizing gross blood loss and transfusion demands. However, concerns remain that intravenously delivered TXA (ivTXA) may increase risks of postoperative convulsive seizures and systemic thrombogenicity. Topical use of TXA (tTXA), being more targeted to the surgical bleeding site while minimizing patient systemic exposure to ivTXA, has been successfully applied to attenuate blood losses and transfusion requirements in hip and knee arthroplasty...

Evaluation of coagulation is vital in the care of the orthopaedic patients, particularly in the subspecialties of trauma, spine, arthroplasty, and revision surgery resulting from blood loss and coagulopathies. Although conventional tests (prothrombin time/international normalized ratio, activated partial thromboplastin time, platelet count, and fibrinogen) are most commonly used, others like thromboelastography (TEG) are also available to the orthopaedic surgeons. TEG is a blood test developed in the 1950s, which provides a snapshot of a patient's coagulation profile by evaluating clot formation and lysis...

Background: Periprosthetic joint infections (PJIs) are devastating complications. Excessive anticoagulation with warfarin is an independent risk factor for PJIs. The use of a dedicated anticoagulation clinic to improve warfarin management has not been proven. Methods: Between 2006 and 2014, we identified 92 patients who were placed on postoperative warfarin, and later developed PJI. These patients were compared to 313 patients who underwent total joint arthroplasty placed on warfarin without developing PJI...
