Cobalt toxic optic neuropathy and retinopathy: Case report and review of the literature

American Journal of Ophthalmology Case Reports, 2020
Purpose: We detail a case of cobalt toxicity with visual and systemic complications, review the pathogenic process for the optic neuropathy and retinopathy, and discuss the controversy of metallic hip prosthesis. Observations: A 59-year-old female with a

Primary stability of cementless threaded acetabular cups at first implantation and in the case of revision regarding micromotions as indicators [PDF]

, 2012
The primary stability of cementless total hip endoprosthesis is of vital importance for proximate, long-term osteointegration. The extent of micromotions between implant and acetabulum is an indicator of primary stability.

Coronal plane alignment of the knee classification system does not reliably predict tibiofemoral joint gaps in arthritic knees undergoing total knee arthroplasty

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Achieving optimal mediolateral balance in extension and flexion is critical for improving outcomes in total knee arthroplasty (TKA). Knee classification tools, like coronal plane alignment of the knee (CPAK), do not directly consider the soft tissue profile of the joint.

Effects of extended stance time on a powered knee prosthesis and gait symmetry on the lateral control of balance during walking in individuals with unilateral amputation

Journal of NeuroEngineering and Rehabilitation, 2019
Background Individuals with lower limb amputation commonly exhibit large gait asymmetries that are associated with secondary health issues. It has been shown that they are capable of attaining improved temporal and propulsive symmetry when walking with a

Successful treatment of periprosthetic joint infection caused by Granulicatella para-adiacens with prosthesis retention: a case report. [PDF]

, 2016
Granulicatella and Abiotrophia spp. are difficult to detect due to their complex nutritional requirements. Infections with these organisms are associated with high treatment failure rates.

Similar fixation of total knee arthroplasty components with medial congruent and cruciate retaining polyethylene inserts. A randomised double‐blinded controlled radiostereometry trial with 24 months of follow‐up

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To assess the influence of a higher constraint medial congruent (MC) versus a cruciate retaining (CR) (gold standard) polyethylene insert on the migration of cemented tibial and femoral components of the Persona Total Knee System. High‐constraint inserts may increase forces on components and potentially affect implant migration and ...

Migration analysis of a metaphyseal anchored short-stem hip prosthesis

Acta Orthopaedica, 2012
Background and purpose Metaphyseal anchored short-stem hip implants were designed to improve load transmission and preserve femoral bone stock. Until now, only few outcome data have been available and migration studies are one of the few ways of ...

Robotic‐assisted burr preparation significantly improves cement penetration but not immediate fixation strength in total knee arthroplasty

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Although robotic‐assisted total knee arthroplasty (TKA) is recognized for improving surgical precision, the effect of its bone preparation technique on cemented fixation remains unclear. This study compared the impact of robotic‐assisted burr versus oscillating saw techniques on cement penetration and fixation strength.

Transverse rotation and longitudinal translation during prosthetic gait - a literature review [PDF]

, 2003
Improved technology allows for more accurate gait analysis to increase awareness of nonoptimized prosthetic gait patterns and for the manufacture of sophisticated prosthetic components to improve nonoptimized gait patterns. However, prescriptions are

Design of Custom Made Prosthesis of the Hip

Tehnicki vjesnik - Technical Gazette, 2019
Replacement of a natural hip joint with an artificial is one of the most commonly used surgical procedures in orthopaedic surgery. This paper describes the methodology of the hip joint prosthesis design, which presents the foundation for the automation of all stages of the development of custom-made prostheses. A general mathematical model based mostly
