Knee arthoplasty: recently developed ceramics offer new solutions

Biomaterials

Abstract

Knee arthroplasty has reached a high degree of reliability. Many of the remaining long-term loosening cases are due to the polyethylene wear debris. The introduction of the alumina ceramic to polyethylene bearing couple had been a promising means for its reduction. The discussion of its applications in total knee replacements shows the possibilities and limitations of this bearing couple. The complete avoidance of the polyethylene debris can be expected from the articulation of alumina ceramic against itself, as long-term follow-up studies of total hip replacements clearly indicate. However, this combination can only be considered with a design of the prostheses in which any incongruity of the articulating surfaces can be excluded. As this necessitates the introduction of an additional component into the relatively narrow space between the femoral condyle and the tibia replacement, a further condition is the availability of a material which, whilst maintaining the tribological advantages of the alumina ceramic, has a much higher mechanical strength than the medical grade alumina ceramic available before. As the specifications of a recently developed modification of an alumina ceramic are in the desired range, with an improvemen...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
