This meta-analysis evaluated preoperative aspiration culture for diagnosing prosthetic joint infection (PJI) in total hip arthroplasty (THA) and total knee arthroplasty (TKA). The pooled sensitivity and specificity were 0.72 (95% confidence interval, 0.65 to 0.78) and 0.95 (0.93 to 0.97), respectively. Subgroup analyses revealed nonsignificant worse diagnostic performance for THA than for TKA (...

BackgroundThe aims of this study were to assess and quantify hip abductor muscle strength deficits after total arthroplasty (THA) determine associations with external factors.MethodsStudies reporting on before and/or THA performed for osteoarthritis or atraumatic osteonecrosis the considered inclusion. Data sources Embase, Medline, Cochrane Central Register Controlled Trials. Muscle affected si...

This study was designed to evaluate trends in incidence and treatment patterns for intracapsular hip fractures and to evaluate risk factors for complications and mortality. Patients with an intracapsular hip fracture who underwent internal fixation, hemiarthroplasty, or total hip arthroplasty (THA) were identified from a 5% nationwide sample of Medicare data (1998-2007). The authors identified ...

Abstract Background Preoperative templating in total hip arthroplasty (THA) is mandatory to achieve appropriate offset and leg length equality. However, methods using the contralateral might be susceptible errors resulting from side-differences femoral morphology. The distance of lesser trochanter head center (LTFHD) a frequently used reference parameter for preoperative planning intraoperative...

BACKGROUND While navigation systems have been developed to increase implantation accuracy in total hip arthroplasty (THA), they are not yet sufficiently versatile or commonly used. Therefore, to elevate the appeal of such systems, we have developed HipCOMPASS, a simple and effective mechanical angle indicator for use in supine THA. QUESTIONS/PURPOSES How accurate is the mean cup orientation [...

Introduction: Stability of the acetabular component is a critical factor in success primary and revision total hip arthroplasty (THA) procedures. As such, identification implant surface characteristics that maximize stability cup an important research objective. While titanium has historically been most commonly used material, proportion THA procedures utilizing porous tantalum (PTa) implants i...

Abstract Background Accurate preoperative planning is an important step for accurate reconstruction in total hip arthroplasty (THA). Presently, completed using either a two-dimensional (2D) template or three-dimensional (3D) mimics software. With the development of artificial intelligence (AI) technology, AI HIP, software based on can quickly and automatically identify acetabular femur morpholo...

BACKGROUND Despite the overall effectiveness of total hip arthroplasty (THA), a subset of patients remain dissatisfied with their results because of persistent pain or functional limitations. It is therefore important to develop predictive tools capable of identifying patients at risk for poor outcomes before surgery. QUESTIONS/PURPOSES The purpose of this study was to use preoperative patien...
