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 ...

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.

Unilateral Single Joint Arthritis Changes Joint Power in Unaffected Joints

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Pain and disability associated with arthritis of the hip, knee, or ankle is well‐documented. However, data on joint power and how arthritis in one joint affects power in that joint and in unaffected joints are limited. This study asks if arthritis in any one joint leads to (1) loss of power in that affected joint compared to the contralateral,

The impact of elective total hip and knee arthroplasty on physical performance in orthogeriatric patients: a prospective intervention study

BMC Geriatrics, 2023
Background Osteoarthritis is a prevalent condition in older adults that leads to reduced physical function in many patients and ultimately requires hip or knee replacement.

Friction in metal-on-metal total disc arthroplasty: effect of ball radius [PDF]

, 2012
Total Disc Arthroplasty (TDA) can be used to replace a degenerated intervertebral disc in the spine. There are different designs of prosthetic discs, but one of the most common is a ball-and-socket combination.

Advanced Testing Protocols Simulate Failures and Validate Antioxidant Polyethylene in Ankle Implants

Journal of Orthopaedic Research, EarlyView.
Abstract Total ankle replacement (TAR) has become an effective treatment for end‐stage ankle osteoarthritis. Multiple factors, including patient characteristics, surgical technique, alignment, and bearing surfaces, influence TAR survivorship. Polyethylene (PE) fatigue is a key consideration in improving outcomes.
