BACKGROUND Screening methods that use automated data may streamline surgical site infection (SSI) surveillance and improve the accuracy and comparability of data on SSIs. We evaluated the use of automated inpatient diagnosis codes and pharmacy data to identify SSIs after arthroplasty. METHODS This retrospective cohort study at 8 hospitals involved weighted, random samples of medical records f...

Obese populations present challenges for acetabular cup placement during total hip arthroplasty (THA). This study examines the accuracy of acetabular cup inclination and version in the obese patient with robotic-assisted computer navigation. A total of 105 patients underwent robotic-assisted computer navigation THA with a posterior approach. Groups were divided on body mass index (BMI, kg/m(2))...

Total hip arthroplasty (THA) is a highly effective procedure, however national registries show that the average age has decreased and younger patients are more likely to require revision. Long-term THA follow-up traditionally been suggested detect aseptically failing reduce dangers associated with significant modifications services presently in decline. To assess influence of long-term on total...

BACKGROUND Metal-on-metal hip resurfacing arthroplasty (MoM HRA) may offer potential advantages over total hip arthroplasty (THA) for certain patients with advanced osteoarthritis of the hip. However, the cost effectiveness of MoM HRA compared with THA is unclear. QUESTIONS/PURPOSES The purpose of this study was to compare the clinical effectiveness and cost-effectiveness of MoM HRA to THA. ...

Introduction: Total hip arthroplasty (THA) after proximal femoral fixation is a challenging procedure due to possible hardware-related complications. Case presentation: A 78-year-old female with hip osteoarthritis had a proximal femoral osteotomy fixed using a blade plate in the same femur 41 years ago. A two-step approach was planned. After a challenging...

BACKGROUND We intended to clarify the hypothesis that minimally invasive total hip arthroplasty (MI-THA) leads to less tissue damage and inflammatory response than does conventional total hip arthroplasty (C-THA). METHODS We performed 30 cases of THA between September 2005 and May 2006 and evaluated these cases prospectively. We chose 15 MI-THA cases for the study group and another 15 C-THA c...

BACKGROUND In the absence of thromboprophylaxis, patients undergoing total hip arthroplasty (THA) are at increased risk for venous thromboembolism (VTE). The objective of this study was to compare the efficacy and safety of edoxaban with enoxaparin for the prevention of VTE after THA in Japan. METHODS This was a phase 3, double-blind, double-dummy, noninferiority study. Patients undergoing el...

BACKGROUND The direct anterior approach for total hip arthroplasty (THA) has generated increased interest recently. The purpose of this study was to compare the duration to failure and reasons for revision of primary THA performed elsewhere and subsequently revised at our institution after the direct anterior vs other nonanterior surgical approaches to the hip. METHODS All primary THAs perfor...

Abstract Background This study compared the early clinical recovery of total hip arthroplasty (THA) using computer navigation systems (nTHA) and robotic arm-assisted THA (rTHA). Methods Thirty prospective subjects who underwent rTHA were clinically to 30 nTHA. Clinical data (surgical time, intraoperative blood loss, pain severity, number days independent walking, Harris Hip Score (HHS) at disch...
