BACKGROUND: More than a million surgeries are performed annually in the United States for hip or knee arthroplasty or hip fracture stabilization. One-fifth of these patients have blood transfusions during their hospital stay. Increases in transfusion rates have caused concern about increased adverse events from unnecessary transfusions. METHODS: We systematically reviewed randomized trials examining the effect of restrictive vs liberal transfusion thresholds on patients having major orthopedic surgery...

BACKGROUND: The goal of patellofemoral arthroplasty (PFA) is to replace damaged cartilage and correct underlying deformities to reduce pain and prevent maltracking. We aimed to determine how PFA modifies patellar height, tilt, and tibial tuberosity-trochlear groove (TT-TG) distance. The hypothesis was that PFA would correct trochlear dysplasia or extensor mechanism malalignment. METHODS: The authors prospectively studied a series of 16 patients (13 women and 3 men) aged 64...

BACKGROUND: Arthroscopic knee surgery frequently precedes total knee arthroplasty (TKA). There have been mixed data on the effect of prior arthroscopic surgery on results of TKA. The purpose of this study was to compare the 10-year Knee Society Score (KSS), survivorship, and complications of TKA in a cohort of patients who had a previous knee arthroscopy to a control cohort. METHODS: A retrospective review of 1315 TKAs who underwent a primary TKA between 2003 and 2004 was performed...

BACKGROUND: A number of studies on total hip arthroplasty have compared highly cross-linked polyethylene (HXLPE) with conventional polyethylene (CPE) liners beyond 10 years. However, the impact of HXLPE on the wear-related reoperation rate is unclear. The purpose of this study was to evaluate the clinical advantage of using a single manufacturer's HXLPE in terms of reducing the reoperation rate. METHODS: The study was a follow-up retrospective cohort study over a mean of 12 years that examined patients aged 45-70 years with cementless total hip arthroplasty using a 26-mm-diameter cobalt-chromium head...

BACKGROUND: Total hip arthroplasty (THA) is one of the most common reoperations after hip arthroscopy. Although arthroscopy causes changes in the hip joint and the surrounding soft tissues that can make THA more challenging, previous reports on arthroscopy before THA have not demonstrated any significant effect on clinical outcomes. METHODS: Patients who underwent a THA following an ipsilateral hip arthroscopy were matched to a control group of THA patients with no history of ipsilateral hip surgery...

BACKGROUND: The use of porous tantalum for the acetabular component in primary total hip arthroplasty (THA) has demonstrated excellent short-term and midterm results. However, long-term data are scarce. The purpose of this prospective study is to report the long-term clinical and radiologic outcome following use of an uncemented porous tantalum acetabular component in primary THA with a minimum follow-up of 17.5 years, in a previously studied cohort of patients. METHODS: We prospectively followed 128 consecutive primary THAs in 140 patients, between November 1997 and June 1999...

BACKGROUND: Readmission rate has emerged as an important metric to measure quality, but varying definitions and timeframes are used. We aimed to evaluate the impact of different readmission definitions (postoperative vs postdischarge) and timeframes (30 vs 90-day) on capturing surgery-related readmissions after primary total joint arthroplasty. METHODS: Patients who underwent primary total hip or knee arthroplasty between January 1, 2013 and December 31, 2015 were included...

BACKGROUND: We aimed to compare in-hospital postoperative complications (IHPC) and in-hospital mortality between patients with and without type 2 diabetes mellitus (T2DM) undergoing primary total hip arthroplasty (THA) and total knee arthroplasty (TKA). METHODS: We analyzed data from the Spanish National Hospital Discharge Database, 2010-2014. We selected patients who had undergone THA (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] code 81...

BACKGROUND: The hip is a common location for metastatic tumors. Due to the high loads placed through the proximal femur, surgery is often indicated to provide pain relief and restore function. Historically, these lesions are reconstructed with a hemiarthroplasty; however, there are few reports on the outcome of these reconstructions. The purpose of this study is to evaluate the outcome of hemiarthroplasty for the treatment of proximal femur metastatic disease, with a specific focus on the rates of conversion to total hip arthroplasty (THA)...

BACKGROUND: Venous thromboembolism (VTE), including pulmonary embolism (PE) and deep vein thrombosis, is a serious complication after total joint arthroplasty (TJA). Risk assessment models are increasingly used to provide patient-specific risk stratification. A recently implemented protocol mandates calculation of a Caprini Score for all surgical patients at our institution. We investigated the accuracy of the Caprini Score in predicting VTE events following TJA. METHODS: A retrospective review of patients undergoing primary total hip (THA) and total knee arthroplasty (TKA) over a 1-year time period was performed...

BACKGROUND: This study aims to evaluate patient reported and functional outcomes following hybrid versus cemented total knee arthroplasty (TKA) in patients, stratified by body mass index (BMI). METHODS: Registry data of patients undergoing primary TKA between January 2004 and January 2013 were collected. Baseline interviews were conducted preoperatively to assess sociodemographic characteristics, BMI, and knee arthritis severity, using the Knee Society Score which consists of the Knee Society Knee Score and the Knee Society Function Score (KSFS) and Oxford Knee Score (OKS)...

BACKGROUND: Maintenance of the native patellar thickness has been deemed important for proper clinical outcomes after total knee arthroplasty (TKA). Our objective was to study the effects of the change in patellar thickness on patient-perceived outcomes (PPOs) after TKA. We hypothesized that reestablishing native patellar thickness after TKA results in better PPOs. METHODS: 819 consecutive patients undergoing primary TKA were studied. Patients were classified according to their postoperative patellar thickness into: (1) less than native patella thickness; (2) equal to native patella thickness; and (3) greater than native patella thickness...

BACKGROUND: The acetabular component orientation in total hip arthroplasty (THA) is of critical importance to the good clinical results. However, traditional widely used cup alignment guides for cup placement are reported to be relatively unreliable. The present study aims at comparing a novel cup alignment guide, which can be attached to our anatomical pelvic plane (APP) pelvic lateral positioner for reducing discrepancies in sagittal pelvic tilt and indicate a targeted cup angle based on the APP, with a conventional cup alignment guide...

BACKGROUND: With the growing opioid crisis in the United States, there has been a push to reduce the utilization of opioids in favor of multimodal analgesia options. The purpose of this study was to evaluate the quality of online resources that patients may use to learn about pain control after total knee arthroplasty (TKA). METHODS: We identified websites using a combination of search terms about TKA and pain control. A novel grading rubric was created with 25 maximum points, consisting of items that were deemed important for patients to know about the subject...

BACKGROUND: Although use of intramedullary hip screws (IMHS) for intertrochanteric (IT) hip fractures has become more common, limited data have suggested difficulties in conversion to hip arthroplasty. The present study investigates whether conversion of failed IT fracture fixation with an intramedullary vs extramedullary device leads to different rates or types of complications or decreased arthroplasty survivorship. METHODS: One hundred eleven patients were converted to hip arthroplasty after previous surgical treatment of an IT fracture from 2000 to 2010...

BACKGROUND: Birmingham hip resurfacing (BHR) has proven to be a good alternative for younger patients with osteoarthritis. Some have asserted that BHR may yield outcomes which are superior to total hip arthroplasty (THA), and that some studies which failed to show a difference were plagued by ceiling effects and lack of sensitivity of outcome measures. The purpose of this study is to compare outcomes of BHR and THA using the "Forgotten Joint" Score-12 (FJS), a more sensitive score with lesser vulnerability to the ceiling effect...

BACKGROUND: There is sparse evidence on the benefit of neuraxial (NA) vs general anesthesia (GA) as the primary anesthetic in postoperative outcomes following bilateral total knee arthroplasty. We sought to elucidate differences in outcomes in this surgical population using a national database. METHODS: We used data from the National Surgical Quality Improvement Program from 2007 to 2013 and compared rates of various postoperative outcomes in propensity-matched cohorts (NA vs GA)...
