New way to evaluate meniscus tear outcomes
Researchers utilize MRI to investigate how tears heal
2015-03-28
(Press-News.org) Las Vegas, NV - An individual's meniscus (cushion in the knee) is one of the most important ligaments in the leg providing stability, load bearing and preservation of the knee joint. It is also one of the most easily injured areas and difficult to fully heal. Researchers presenting their study at today's Specialty Day meeting of the American Orthopaedic Society for Sports Medicine (AOSSM) utilized MRI data to determine the potential for biologic healing following a meniscus tear.
"Little is currently understood about the healing of meniscus tears when a root repair is performed via the pullout technique," said Matthew D. Pepe, MD, one of the study's authors from the Rothman Institute of Orthopaedics in Philadelphia, PA. "Our study provides new insight into how this may occur."
Ten patients were identified for investigation, having undergone a medial meniscus root repair. There were five females and five males in the study group with an average follow-up time of 30 months following surgery. MRI evaluations demonstrated a new tear medial to prior repair in four of nine patients. These four patients show a lack of biologic healing of the root attachment. This indicates significant stress on the area following the repair. Similar findings have also been shown in studies evaluating rotator cuff repair.
"My colleagues and I hope that more fully investigating how meniscus tears heal will lead to improved clinical outcomes for our patients," said Pepe.

Las Vegas, NV - One in three young athletes who undergo ACL surgery experiences re-injury, according to research presented today at the American Orthopaedic Society for Sports Medicine's (AOSSM) Specialty Day. The study examined the long term success of surgery for patients aged 18 years and younger.
"We examined survey data from 242 patients who underwent ACL reconstruction between 1993 and 1998," noted lead author Justin P. Roe, MBBS, FRACS, from North Sydney Orthopaedic and Sports Medicine Centre. "Of this group, 75, or 31% sustained a further injury after at least ...

Las Vegas, NV - Pitching speed, player's height, and pitching for multiple teams may correlate with a history of shoulder and elbow injuries, according to new research released today at the American Orthopaedic Society for Sports Medicine's (AOSSM) Specialty Day.
"Our findings indicate that a 10 inch increase in height is associated with a 20% increase in likelihood of a history of injury, a 10 mile per hour increase in velocity is associated with a 12% increase likelihood of a history of injury, and playing for more than one team is associated with a 22% increase in ...

A study published today in the journal Science found that government biofuel policies rely on reductions in food consumption to generate greenhouse gas savings.
Shrinking the amount of food that people and livestock eat decreases the amount of carbon dioxide that they breathe out or excrete as waste. The reduction in food available for consumption, rather than any inherent fuel efficiency, drives the decline in carbon dioxide emissions in government models, the researchers found.
"Without reduced food consumption, each of the models would estimate that biofuels generate ...

HOUSTON - (March 27, 2015) - Saudi Arabia's role in global energy markets is changing, according to a new paper from an energy expert at Rice University's Baker Institute for Public Policy. The researcher found that the kingdom is reshaping itself as a supplier of refined petroleum products while moving beyond its long-held role as a simple exporter of crude oil.
"A Refined Approach: Saudi Arabia Moves Beyond Crude" examines the growth of Saudi refining, the country's increased domestic demand for crude oil and the geopolitical effects of this development. The paper was ...

In the world of bird fashion, the guys seem to have all the fun: brighter feathers, sharper accessories, more pizzazz.
Researchers going back to Charles Darwin have focused on the contrast between the sexes, attributing the males' brighter colors to their need to attract mates.
A group of researchers at University of Wisconsin-Milwaukee took a different approach, testing a hypothesis that evolution has actually resulted in similarities among the sexes as much as differences.
Looking at nearly 1,000 species of birds, they found that while males often have brighter ...

TAMPA, Fla. - Moffitt Cancer Center researchers are using integrative approaches to study cancer by combining mathematical and computational modeling with experimental and clinical data. The use of integrative approaches enables scientists to study and model cancer progression in a manner that conventional experimental systems are unable to do.
Alexander Anderson, Ph.D., chair of the Department of Integrated Mathematical Oncology (IMO) and Mark Robertson-Tessi, an applied research scientist in IMO, recently published a commentary on an integrative approach used to study ...

The promising new material molybdenum disulfide (MoS2) has an inherent issue that's steeped in irony. The material's greatest asset--its monolayer thickness--is also its biggest challenge.
Monolayer MoS2's ultra-thin structure is strong, lightweight, and flexible, making it a good candidate for many applications, such as high-performance, flexible electronics. Such a thin semiconducting material, however, has very little interaction with light, limiting the material's use in light emitting and absorbing applications.
"The problem with these materials is that they are ...

Scientists working at the National Institute of Standards and Technology (NIST) and the National Institutes of Health (NIH) have devised and demonstrated a new, shape-shifting probe, about one-hundredth as wide as a human hair, which is capable of sensitive, high-resolution remote biological sensing that is not possible with current technology. If eventually put into widespread use, the design could have a major impact on research in medicine, chemistry, biology and engineering. Ultimately, it might be used in clinical diagnostics.
To date, most efforts to image highly ...

March 27, 2015 - For people with low vision who need bioptic telescopic glasses to drive, previous driving experience and the need for more training hours are the main factors affecting performance on driver's license road tests, according to a study in the April issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Wolters Kluwer.
After driving experience is taken into account, visual factors have no significant effect on road test scores in drivers using bioptic devices, report Bradley E. Dougherty, ...

Cold snaps like the ones that hit the eastern United States in the past winters are not a consequence of climate change. Scientists at ETH Zurich and the California Institute of Technology have shown that global warming actually tends to reduce temperature variability.
Repeated cold snaps led to temperatures far below freezing across the eastern United States in the past two winters. Parts of the Niagara Falls froze, and ice floes formed on Lake Michigan. Such low temperatures had become rare in recent years. Pictures of icy, snow-covered cities made their way around ...
