The Influence of Cup Orientation on the Primary Fixation of a Hemispherical Cementless Acetabular Cup: A Cohort Based Finite Element Study

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Cup orientation has been investigated in detail with respect to risk of dislocation, however, the impact on the primary fixation of cementless cups is poorly understood. The aim of this study was to assess the influence acetabular component orientation on the primary fixation of cementless acetabular cups using an in silico clinical trial ...

Reconstruction of Proximal Metaphyseal Femoral Defects Using Trabecular Metal Augments in Revision Total Hip Arthroplasty

Arthroplasty Today, 2021
Porous tantalum augments are widely used in revision total hip arthroplasty for the reconstruction of severe bone defects. Here, we present the first 3 cases who underwent femoral revision arthroplasty using standard distal femoral and proximal tibial ...

Effects of Early Physical Therapy Intervention in the Rehabilitation of a Total Hip Arthroplasty Revision with an Anterior Approach: Case Report [PDF]

, 2015
Advances in medical technology have greatly changed the way surgeons perform surgical procedures. The push by surgeons and their patients for less invasive surgeries has caused surgeons to turn to an anterior approach for total hip arthroplasty and ...

Pelvic Tilt Increases the Risk of Impingement and Alters Impingement Type in Total Hip Arthroplasty: A Patient‐Specific Simulation Study

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Impingement is a significant complication following total hip arthroplasty (THA), resulting in restricted range of motion (ROM). Pelvic tilt (PT) and its variation could alter both post‐THA ROM and impingement types, which remains relatively unexplored in the literature.

Revision Total Knee Arthroplasty Using Robotic Arm Technology

Arthroplasty Today, 2022
Total knee arthroplasty (TKA) is a highly successful operation for the treatment of end-stage osteoarthritis of the knee. Increasing use of computer-assisted and robotic-assisted total joint arthroplasty has been shown to improve component position, with

Automated Acetabular Defect Reconstruction and Analysis for Revision Total Hip Arthroplasty: A Computational Modeling Study

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Revision total hip arthroplasty (rTHA) involving large acetabular defects is associated with high early failure rates, primarily due to cup loosening. Most acetabular defect classification systems used in surgical planning are based on planar radiographs and do not encapsulate three‐dimensional geometry and morphology of the acetabular defect.

Catastrophic wear in a metal-on-ceramic total hip arthroplasty [PDF]

, 2007
A 51-year-old woman came to our clinic 6 months after a right total hip arthroplasty. She had noticed a slowly growing mass in the proximal thigh and referred progressive pain in the right groin.

Similar risk of complete revision for infection with single-dose versus multiple-dose antibiotic prophylaxis in primary arthroplasty of the hip and knee:results of an observational cohort study in the Dutch Arthroplasty Register in 242,179 patients [PDF]

, 2020
Background and purpose - The optimal type and duration of antibiotic prophylaxis for primary arthroplasty of the hip and knee are subject to debate. We compared the risk of complete revision (obtained by a 1- or 2-stage procedure) for periprosthetic ...

The weight of complications: high and low BMI have disparate modes of failure in total hip arthroplasty

Arthroplasty
Background Body mass index (BMI) has been shown to influence risk for revision total hip arthroplasty (rTHA), but few studies have specifically examined which causes of rTHA are most likely in different BMI classes.

MODERN TRENDS IN ORTHOPEDICS: REVISION OF THE ACETABULAR AND FEMORAL COMPONENTS

Travmatologiâ i Ortopediâ Rossii, 2012
The revision rate of total hip arthroplasty (THA) is increasing with growth of number primary THA. The problems of revision procedures are associated with high technical demands and high incidence of poor results.
