Comparison of External Rotation Torque of Short External Rotator Muscles in Hip Flexion Position

Journal of Orthopaedic Research, EarlyView.
Preserving the short external rotator muscles of the hip helps prevent dislocation after total hip arthroplasty, but it's unclear which muscles are most critical. This study quantified the external rotation torque in cadaveric hips and found that the obturator externus provides the highest torque during deep hip flexion, where dislocations often occur.

Outcome in design-specific comparisons between highly crosslinked and conventional polyethylene in total hip arthroplasty: 163,368 hip replacements in the Nordic Arthroplasty Register Association database with 5–11 years of follow-up

Acta Orthopaedica, 2017
Background and purpose — Most registry studies regarding highly crosslinked polyethylene (XLPE) have focused on the overall revision risk. We compared the risk of cup and/or liner revision for specific cup and liner designs made of either XLPE or ...

The Effect of Body Mass Index Class on Patient-Reported Health-Related Quality of Life Before and After Total Hip Arthroplasty for Osteoarthritis

JBJS Open Access, 2020
Background:. Overweight status and obesity represent a global epidemic, with serious consequences at the individual and community levels. The number of total hip arthroplasties (THAs) among overweight and obese patients is expected to rise.

Cobalt cardiomyopathy in hip arthroplasty [PDF]

Arthroplasty Today, 2019
Cobalt toxicity-related cardiomyopathy in hip arthroplasty has recently been reported in the literature. The purpose of this review is to identify and assess available published evidence of cardiomyopathy in hip arthroplasty patients and to derive recommendations for management.We evaluated 23 cases reported until October 2018 and stratified them into ...

Reduced Muscle Strength Can Alter the Impact of Gait Modifications on Knee Cartilage Mechanics

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Muscle strength can substantially influence knee joint loading, stability, and cartilage biomechanics, all of which are important factors in the onset and progression of knee osteoarthritis (KOA). Noninvasive rehabilitation methods, such as gait modifications, are suggested to effectively alter knee joint loading, potentially helping to ...

Contemporary posterior surgical approach in total hip replacement: still more reoperations due to dislocation compared with direct lateral approach? An observational study of the Swedish Hip Arthroplasty Register including 156,979 hips

Acta Orthopaedica, 2019
Background and purpose — The direct lateral approach (DLA) and the posterior approach (PA) are the most common surgical approaches in total hip replacement (THR) in Sweden.

A Machine Learning Approach to Microcalorimetric Pattern Classification of Pathogens in Synovial Fluid

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Isothermal microcalorimetry (IMC) is a promising tool for diagnosing periprosthetic joint infection (PJI), based on real‐time measurement of growth‐related heat production of pathogens, and faster than conventional microbial cultures. However, the feasibility of identifying specific pathogens in clinical samples using IMC has yet to be proven.

Reduced risk of reoperation after treatment of femoral neck fractures with total hip arthroplasty: A matched pair analysis

Acta Orthopaedica, 2017
Background and purpose — Femoral neck fractures (FNFs) are commonly treated with some kind of arthroplasty, but evidence on whether to use hemiarthroplasty (HA) or total hip arthroplasty (THA) is lacking.
