The aim of this study was to examine the clinical characteristics of patients who required revision and the rate of early complications after revision for metal-on-metal total hip arthroplasty (MOM THA) and metal-on-polyethylene total hip arthroplasty (MOP THA). Matched cohorts were selected by retrospective review from a single-center database of revision THAs for failed MOM and MOP THAs from ...

BACKGROUND AND OBJECTIVES High-volume local infiltration analgesia (LIA) is widely applied as part of a multimodal pain management strategy in total hip arthroplasty (THA). However, methodological problems hinder the exact interpretation of previous trials, and the evidence for LIA in THA remains to be clarified. Therefore, we evaluated whether intraoperative high-volume LIA, in addition to a m...

BACKGROUND Research using large administrative databases has substantially increased in recent years. Accuracy with which comorbidities are represented in these databases has been questioned. The purpose of this study was to evaluate the extent of errors in obesity coding and its impact on arthroplasty research. METHODS Eighteen thousand thirty primary total knee arthroplasties (TKAs) and 10,...

BACKGROUND Total hip arthroplasty (THA) is an increasingly common procedure among elderly individuals. Although conversion THA is currently bundled in a diagnosis related group (DRG) with primary THA, no study has identified whether patients undergoing conversion THA better resemble patients undergoing primary THA or revision THA. The American College of Surgeons National Surgical Quality Impro...

Metal-on-metal total hip arthroplasty (THA) has generated much attention in the media because of early failure of certain implant systems. This study assessed the quality, accuracy, and readability of online information on metal-on-metal THA. The search terms "metal-on-metal hip replacement" and "metal hip replacement" were entered into the 3 most popular search engines. Information quality was...

We compared differences in isometric strength between older adults who have undergone elective unilateral total hip arthroplasty (THA) and completed rehabilitation with a population of community-dwelling older adults who have not had THA. The study was a cross-sectional design, and 22 unilateral THA subjects and 38 community-dwelling older adults participated. THA subjects received on average 1...

Tetracosahexaenoic acid (THA, 24:6n-3) has been shown to have the strongest ability to suppress accumulation of lipids in HepG2 cells among well-known n-3 highly unsaturated fatty acids, such as EPA and DHA. In this study, a method for mass production of THA was investigated using distributions of THA and DHA in thirty-two marine organisms, such as starfishes, right-eyed flounders, shellfishes,...

(1) Background: Metal-on-metal (MoM) total hip arthroplasty (THA) and resurfacing (HRA) was presumed to provide superior functional outcomes compared metal-on-polyethylene (MoP) THA. (2) Methods: We muscle mass, power, step test asymmetry, patient-reported between MoM THA/HRA MoP A of 51 THA/HRAs 23 THAs participated in the cross-sectional study at a mean 6.5 (2.4–12.5) years postoperatively. M...

PURPOSE The purpose of this study is to compare the perioperative blood loss in primary non-cemented total hip arthroplasty (THA) performed for rapidly destructive coxarthrosis (RDC) with the perioperative blood loss in primary non-cemented THA for typical osteonecrosis of the femoral head (ONFH). MATERIALS AND METHODS From January 2000 to December 2013, 19 patients were diagnosed with RDC (g...

BACKGROUND For minority populations in the United States, especially African Americans, Hispanics, and Native Americans, healthcare disparities are a serious problem. The literature documents racial and ethnic utilization disparities with regard to THA and TKA. QUESTIONS/PURPOSES We therefore (1) defined utilization disparities for total joint arthroplasty in racial and ethnic minorities, (2)...
