(Press-News.org) HUNTINGTON, W.Va. - An innovative study at Marshall University published in ArthroplastyToday explores the use of robotic-assisted joint replacement in revision knee scenarios, comparing the pre- and post-revision implant positions in a series of revision total knee arthroplasties (TKA) using a state-of-the-art robotic arm system.
In this retrospective study, the orthopaedic team at the Marshall University Joan C. Edwards School of Medicine and Marshall Health performed 25 revision knee replacements with a robotic assisted computer system. The procedure involved placing new implants at the end of the thighbone and top of the shinbone with the computer's aid to ensure the knee was stable and balanced throughout the range of motion. Researchers then carefully compared the initial positions of the primary implants with the final planned positions of the robotic revision implants for each patient, assessing the differences in millimeters and degrees.
The analysis found that exceedingly small changes in implant position significantly influence the function of the knee replacement. Robotic assistance during revision surgery has the potential to measure these slight differences. In addition, the computer system can help the surgeon predict what size implant to use as well as help to balance the knee for stability.
“Robotic-assisted surgery has the potential to change the way surgeons think about revision knee replacement,” said Matthew Bullock, D.O., associate professor of orthopaedic surgery and co-author on the study. “The precision offered by robotic-assisted surgery not only enhances the surgical process but also holds promise for improved patient outcomes. Besides infection, knee replacements usually fail because they become loose from the bone or because they are unbalanced leading to pain and instability. When this happens patients can have difficulty with activities of daily living such as walking long distances or negotiating stairs.”
The study underscores the importance of aligning the prosthesis during revision surgery. The research also suggests potential advantages, including appropriately sized implants that can impact the ligament tension which is crucial for functional knee revisions.
“These findings open new doors in the realm of revision knee arthroplasty,” said Alexander Caughran, M.D., assistant professor of orthopaedic surgery and co-author on the study. “We continue to collect more data for future studies on patient outcomes after robotic revision knee replacement. We anticipate that further research and technological advancements in the realm of artificial intelligence will continue to shape the landscape of orthopaedic surgery.”
In addition to Bullock and Caughran, co-authors from Marshall University include Micah MacAskill, M.D., resident physician; Richard Peluso, M.D., resident physician; Jonathan Lash, M.D., resident physician; and Timothy Hewett, Ph.D., professor.

New vaccine design uses immunity against influenza to offer faster protection against emerging pathogens
2024-01-17
RIVERSIDE, Calif. -- After COVID vaccination, it usually takes weeks for our bodies to develop protective antibody responses. Imagine, however, a vaccine that speeds up the production of antibodies against SARS-CoV-2, the virus that spreads COVID-19.
A research team led by Rong Hai, an associate professor of microbiology and plant pathology at the University of California, Riverside, has developed such a vaccine by using preexisting immunity to a separate virus (the influenza virus) to help kickstart the process of making antibodies ...
How do controllable risk factors for dementia vary by race, ethnicity?
2024-01-17
MINNEAPOLIS – Approximately 23% of people diagnosed with Alzheimer’s disease or another related dementia in their 60s and later have cases that can be explained by controllable risk factors such as high blood pressure, diabetes, physical inactivity, and too little or too much sleep, and that percentage varies depending on race and ethnicity, according to a new study published in the January 17, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology. When including APOE ε4, a gene variant associated with the strongest genetic risk for late-age Alzheimer’s disease, the study found about a third of cases could be explained ...
For people with migraine, feelings of stigma may impact disability, quality of life
2024-01-17
MINNEAPOLIS – Migraine can impact many aspects of a person’s life, but less is known about how feelings of stigma about the disease affect quality of life. For people with migraine, these feelings of stigma were linked to more disability, increased disease burden and reduced quality of life, according to new research published in the January 17, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology.
“Stigma is common where the disease is not readily apparent to others, and there is indication that it could be especially relevant for those living with migraine,” said study author Robert Evan Shapiro, ...
NIH-developed HIV antibodies protect animals in proof-of-concept study
2024-01-17
WHAT:
Three different HIV antibodies each independently protected monkeys from acquiring simian-HIV (SHIV) in a placebo-controlled proof-of-concept study intended to inform development of a preventive HIV vaccine for people. The antibodies—a human broadly neutralizing antibody and two antibodies isolated from previously vaccinated monkeys—target the fusion peptide, a site on an HIV surface protein that helps the virus fuse with and enter cells. The study, published in Science Translational Medicine, was led by the Vaccine Research Center (VRC) at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.

Social networks of sanctuary-living Grauer’s gorillas provide unique insights into the behavior of a critically endangered species and inform on their care and future release.
Adult female gorillas are at the centre of social networks in a sanctuary-living Grauer's Gorilla group, according to social network analysis which also finds them to be the most gregarious.

Certain personality traits linked to college students’ sense of belonging
2024-01-17
In a study of nearly 5,000 North American first-year college students, those who were more extraverted, more agreeable, or less neurotic were more likely to feel a greater sense of belonging at school. Alexandria Stubblebine, an independent researcher in Ocala, Florida, USA, and colleagues present these findings in the open-access journal PLOS ONE on January 17, 2024.
Prior research has suggested that one’s personality traits are associated with one’s general sense of belonging. Within a college-specific context, other research has linked a secure sense of belonging to many positives, such as better academic performance and better mental health. Some studies have investigated ...
Worldwide, we are living longer and the male-female longevity gap is shrinking
2024-01-17
When it comes to trends in mortality over the last thirty years, countries around the world can be grouped into five clusters, roughly representing the five continents, according to a new study published January 17, 2024, in the open-access journal PLOS ONE by David Atance of Universidad de Alcalá, Spain, and colleagues. While the clusters follow different trajectories, they share some commonalities, including longer life expectancies and fewer disparities between genders and groups of countries with different mortality and longevity indicators.
Most countries in the world have seen improvements in longevity over the last two centuries, ...
