Why do so many pro soccer players develop osteoarthritis?

2025-10-22
(Press-News.org) A new paper in Rheumatology, published by Oxford University Press, finds that retired UK male professional football players who reported foot or ankle injuries during their careers were more likely to develop osteoarthritis in retirement. Retired players treated routinely with cortisone injections for their injuries were even more likely to report osteoarthritis.

Professional football is a high-speed contact sport with high risk of injury. Foot and ankle injuries are particularly common, with ankle sprains being the most regular ankle injury and metatarsal fractures the most frequent foot injury. These injuries occur more often during football matches than in practice due to the high speed, jumping, frequent changes in direction, and competitive nature of the game. Joint injury can lead to pain, swelling and damage to the articular cartilage and other joint tissues and result in subsequent foot/ankle osteoarthritis, which can result in disability or chronic pain.

Although injury is widespread in male professional footballers—almost 25% of players suffer foot or ankle injuries during their careers—the widespread use of injection therapies such as corticosteroids, local anesthetic, platelet-rich plasma, and hyaluronic acid remains controversial due to concerns about their long-term side-effects (and limited evidence supporting the effectiveness of such treatment).

Injections can alleviate pain and allow players to return to games more quickly. However, the treatment may hide underlying joint damage and could accelerate joint structural deterioration over time. The frequent use of injections may also worsen cartilage damage, particularly when combined with the high physical demands required in professional football.

Researchers here examined retired UK male football players between August 2020 and October 2021 about cases in which a general practitioner diagnosed foot/ankle osteoarthritis or preformed forefoot/ankle surgery after the players’ retirement. Of the 424 retired professional football players studied, the investigators reported that 73 percent of retired players with osteoarthritis reported foot or ankle injuries, and 75 percent of players with osteoarthritis reported treatment with corticosteroid injections over the course of their careers.

The researchers caution that while corticosteroid injections are associated with higher rates of osteoarthritis, this does not necessarily mean injections are making osteoarthritis more likely, as injections are often given after injuries, that may have linked injections to osteoarthritis. The investigators do point out that retired football players with osteoarthritis did report a higher number of injections into a single ankle during a season, and many received more than four injections a season, which is more than what’s recommended by physicians. 

“Our findings clearly show that a significant foot or ankle injury during a player’s career is a major, modifiable risk factor of osteoarthritis late in life,” said the study’s chief investigator, Weiya Zhang.

The paper, “Injury and local injection and the risk of foot/ankle osteoarthritis: a case-control study in retired UK male professional footballers,” is available (at midnight on October 22nd) at https://doi.org/10.1093/rheumatology/keaf518.

Successful ground-to-satellite laser communications applying next-generation error correction codes, mitigating atmospheric turbulence

2025-10-22
Abstract The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki Ph.D.) and the Nagoya Institute of Technology (NITech, President: OBATA Makoto), collaborated with the Japan Aerospace Exploration Agency (JAXA), have achieved the world’s first successful demonstration of next-generation error correction codes, mitigating the impact of atmospheric turbulence on ground-to-satellite laser communications. Atmospheric turbulence in ground-to-satellite laser links is known to cause fading, resulting in burst data errors. Error correction codes are one of the key technologies to mitigate such effects. In this experiment, ...

Photosynthesis without the burn

2025-10-22
Too much sun can ruin a day at the beach. It can also ruin photosynthesis, scorching plants and other organisms that depend on capturing sunlight for energy. Beneath the waves, though, algae have found a clever shield. Osaka Metropolitan University researchers and their colleagues discovered that a pigment called siphonein helps marine green algae keep photosynthesis humming, without the burn. Photosynthetic organisms rely on delicate light-harvesting complexes (LHCs) to capture sunlight for energy. During photosynthesis, chlorophyll absorbs light and enters an excited ...

Not hunters but collectors: the bone that challenges the ‘humans wiped out Australian megafauna’ theory

2025-10-22
New research led by UNSW Sydney palaeontologists challenges the idea that indigenous Australians hunted Australia’s megafauna to extinction, suggesting instead they were fossil collectors. The research published today in the journal Royal Society Open Science, opens in a new window focuses on the fossilised tibia (lower leg bone) of a now-extinct, giant ‘sthenurine’ kangaroo. Found in Mammoth Cave in southwestern Australia around the time of the First World War, the bone was later determined to be hard evidence, opens in a new window showing that Indigenous Australians hunted megafauna. Renowned palaeontologist and expert on Australia’s ...

Discovery of new mechanism concerning plasma confinement performance

2025-10-22
Around the world, research is advancing to efficiently confine fusion plasma and harness its immense energy for power generation. However, it is known that turbulence occurring at various scales within the plasma causes the release of plasma energy and constituent particles, degrading the confinement performance. Elucidating this physical phenomenon and suppressing performance degradation is critically important. Particularly in the high-temperature plasma experiments currently conducted worldwide, micro-scale (just a few centimeters) turbulent eddies forming at various locations within the plasma significantly impact this confinement ...

Humans evolved fastest amongst the apes

2025-10-22
Humans evolved large brains and flat faces at a surprisingly rapid pace compared to other apes, likely reflecting the evolutionary advantages of these traits, finds a new analysis of ape skulls by UCL researchers.  The paper, published in the journal Proceedings of the Royal Society B, analysed how the evolutionary diversity of the skulls of humans and other related apes evolved over millions of years. They found that the skull structure for humans evolved substantially faster than that of any other closely ...

Biochar and wetter soils offer breakthrough path to slash farm emissions without cutting crop yields

2025-10-22
Raising groundwater levels and adding biochar to agricultural peat soils could dramatically cut greenhouse gas emissions while maintaining healthy crop production, according to a new study from Bangor University. The study, published in Biochar (2025), tested how water table management and biochar, a charcoal-like soil additive made from plant biomass, affect carbon dioxide, methane, and nitrous oxide emissions in peat-based farming systems. Although drained peats are among the world’s most productive ...

New biochar-enhanced cement could lock away more carbon dioxide

2025-10-22
A research team from Hefei University of Technology, Zhejiang University, and South China University of Technology has discovered that adding specially treated biochar to cement can significantly improve its ability to capture and store carbon dioxide while strengthening the material itself. Cement production is one of the world’s largest sources of CO₂ emissions. Finding cost-effective ways to store carbon directly in building materials could help reduce the industry’s environmental footprint. In the new study, scientists explored how modifying biochar, ...

Strong evidence supports skin-to-skin contact after birth as standard care

2025-10-22
Immediate skin-to-skin contact between newborns and their mothers offers a better start in life, improving a number of key health metrics, according to a newly-updated Cochrane review. The review found that babies who have skin-to-skin contact with their mother within the first hour of birth are more likely to see a variety of benefits, including exclusive breastfeeding, optimal body temperatures and blood sugar levels. While possible benefits for the mother were also studied, such as effects on blood loss and timing of placental delivery, the evidence was less certain. Skin-to-skin involves placing the naked newborn on the mother’s uncovered chest immediately ...

Why it’s not just about money: Who goes to the ballet, opera and symphony

2025-10-21
Why do some people regularly attend the opera, visit art galleries, or go to classical music concerts—while others rarely, if ever, do? The easy answer might be, “They can’t afford it.” But according to recent research from the University of California San Diego Rady School of Management, the real explanation goes far beyond money. The new paper —  published in the Journal of the Association for Consumer Research and coauthored by Joe Gladstone, an assistant professor of behavioral ...

Daily step counts of 4,000 or more tied to reduced risk of heart disease, mortality in older women

2025-10-21
  Mass General Brigham researchers found that older women who took 4,000 steps on just one or two days a week had a 27% reduction in risk of cardiovascular disease and 26% reduction in risk of death compared to those who got less steps The study found that the number of steps taken rather than any daily pattern of stepping was tied to these risk reductions Tracking daily steps has become a staple exercise metric as smart devices keep count with ease. This physical activity stimulates bodily repair and maintenance, which is especially important as we age. But how many steps do you need to reap health benefits? A new study by investigators ...
