Most people with knee osteoarthritis can control their pain and improve their mobility without surgery, according to updated treatment guidelines from the Australian Commission on Safety and Quality in Health Care.

So what is knee osteoarthritis and what are the best ways to manage it?

More than 2 million Australians have osteoarthritis

Osteoarthritis is the most common joint disease, affecting 2.1 million Australians. It costs the economy A$4.3 billion each year.

Osteoarthritis commonly affects the knees, but can also affect the hips, spine, hands and feet. It impacts the whole joint including bone, cartilage, ligaments and muscles.

Most people with osteoarthritis have persistent pain and find it difficult to perform simple daily tasks, such as walking and climbing stairs.

Is it caused by ‘wear and tear’?

Knee osteoarthritis is most likely to affect older people, those who are overweight or obese, and those with previous knee injuries. But contrary to popular belief, knee osteoarthritis is not caused by “wear and tear”.

Research shows the degree of structural wear and tear visible in the knee joint on an X-ray does not correlate with the level of pain or disability a person experiences. Some people have a low degree of structural wear and tear and very bad symptoms, while others have a high degree of structural wear and tear and minimal symptoms. So X-rays are not required to diagnose knee osteoarthritis or guide treatment decisions.

Telling people they have wear and tear can make them worried about their condition and afraid of damaging their joint. It can also encourage them to try invasive and potentially unnecessary treatments such as surgery. We have shown this in people with osteoarthritis, and other common pain conditions such as back and shoulder pain.

This has led to a global call for a change in the way we think and communicate about osteoarthritis.

What’s the best way to manage osteoarthritis?

Non-surgical treatments work well for most people with osteoarthritis, regardless of their age or the severity of their symptoms. These include education and self-management, exercise and physical activity, weight management and nutrition, and certain pain medicines.

Education is important to dispel misconceptions about knee osteoarthritis. This includes information about what osteoarthritis is, how it is diagnosed, its prognosis, and the most effective ways to self-manage symptoms.

Health professionals who use positive and reassuring language can improve people’s knowledge and beliefs about osteoarthritis and its management.

Many people believe that exercise and physical activity will cause further damage to their joint. But it’s safe and can reduce pain and disability. Exercise has fewer side effects than commonly used pain medicines such as paracetamol and anti-inflammatories and can prevent or delay the need for joint replacement surgery in the future.

Many types of exercise are effective for knee osteoarthritis, such as strength training, aerobic exercises like walking or cycling, Yoga and Tai chi. So you can do whatever type of exercise best suits you.

Increasing general physical activity is also important, such as taking more steps throughout the day and reducing sedentary time.

Weight management is important for those who are overweight or obese. Weight loss can reduce knee pain and disability, particularly when combined with exercise. Losing as little as 5–10% of your body weight can be beneficial.

Pain medicines should not replace treatments such as exercise and weight management but can be used alongside these treatments to help manage pain. Recommended medicines include paracetamol and non-steroidal anti-inflammatory drugs.

Opioids are not recommended. The risk of harm outweighs any potential benefits.

What about surgery?

People with knee osteoarthritis commonly undergo two types of surgery: knee arthroscopy and knee replacement.

Knee arthroscopy is a type of keyhole surgery used to remove or repair damaged pieces of bone or cartilage that are thought to cause pain.

However, high-quality research has shown arthroscopy is not effective. Arthroscopy should therefore not be used in the management of knee osteoarthritis.

Joint replacement involves replacing the joint surfaces with artificial parts. In 2021–22, 53,500 Australians had a knee replacement for their osteoarthritis.

Joint replacement is often seen as being inevitable and “necessary”. But most people can effectively manage their symptoms through exercise, physical activity and weight management.

The new guidelines (known as “care standard”) recommend joint replacement surgery only be considered for those with severe symptoms who have already tried non-surgical treatments.

I have knee osteoarthritis. What should I do?

The care standard links to free evidence-based resources to support people with osteoarthritis. These include:

If you have osteoarthritis, you can use the care standard to inform discussions with your health-care provider, and to make informed decisions about your care.

  • The Vagina Bible – by Dr. Jen Gunter

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    The vagina is mysterious to most men, and honestly, also to a lot of women. School education on this is minimal, if even extant, and as an adult, everyone’s expected to “just know” stuff. However, here in reality, that isn’t how knowledge works.

    To remedy this, gynecologist Dr. Jen Gunter takes 432 pages to give us the low-down and the ins-and-outs of this remarkable organ that affects, and is affected by, a lot of the rest of our health.

    (On which note, if you think you already know it, ask yourself: could you write 432 pages about it? If not, you’ll probably still learn some things from this book)

    Stylistically, this book is more of a textbook in presentation, but the writing is still very much easy-reading. The focus is mostly on anatomy and physiology, though she does give due attention to relevant healthcare options; what’s good, what’s bad, and what’s just plain unnecessary. In such cases, she always has plenty of science to hand; it’s never just “one woman’s opinion”.

    If the book has a downside, it’s that (based on other reviews) it seems to upset some readers with unwelcome truths, but that’s more in the vein of “she’s right, of course, but I didn’t like reading it”.

    Bottom line: if you have a vagina, or spend any amount of time in close proximity to one, then this is a great book for you.

  • In Praise Of Walking – by Dr. Shane O’Mara

    At 10almonds we talk often of the health benefits of walking, so what’s new here?

    As the subtitle suggests: a new scientific exploration!

    Dr. Shane O’Mara is a professor of experimental brain research—and a keen walker. Combining his profession and his passion, he offers us a uniquely well-grounded perspective.

    While the writing style is very readable, there’s a lot of science referenced here, with many studies cited. We love that!

    We begin our journey by learning what we have in common with sea squirts, and what we have different from all other apes. What we can learn from other humans, from toddlers to supercentenarians.

    As one might expect from a professor of experimental brain research, we learn a lot more about what walking does for our brain, than for the rest of our body. We’ve previously talked about walking and cardiovascular health, and brown adipose tissue, and benefits to the immune system, but this book remains steadfastly focused on the brain.

    Which just goes to show, what a lot there is to say for the science-based benefits to our brain health, both neurologically and psychologically!

    One of the things at which Dr. O’Mara excels that this reviewer hasn’t seen someone do so well before, is neatly tie together the appropriate “why” and “how” to each “what” of the brain-benefits of walking. Not just that walking boosts mood or creativity or problem-solving, say, but why and how it does so.

    Often, understanding that can be the difference between being motivated to actually do it or not!

    Bottom line: if there’s a book that’ll get you lacing up your walking shoes, this’ll be the one.

  • Lemon vs Lime – Which is Healthier?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Our Verdict

    When comparing lemons to limes, we picked the lemons.

    Why?

    This one’s simple today. They’re both comparable fruits in most ways, and their macro profiles are almost identical. When it comes to vitamins, however, they stand apart a little.

    Both are most well-known for their vitamin C content, but lemons contain about 2x the vitamin C of limes.

    In other vitamins, they’re not too far apart. Technically limes have 2x the vitamin A, but this doesn’t count for much because it’s a case of “two times almost nothing is still almost nothing”.

    In the category of minerals, neither fruit is a very good source of most minerals, and the minerals they do have, are mostly more or less the same.

    Both are acidic, and this can have blood sugar benefits in both cases (and, if not careful, damage tooth enamel in both cases). Nothing to set either apart from the other here.

    So, it comes down to the vitamin C! In which category, lemons take the prize with their higher content.

  • The Conquest of Happiness – by Bertrand Russell

    When we have all our physical needs taken care of, why are we often still not happy, and what can we do about that?

    Mathematician, philosopher, and Nobel prizewinner Bertrand Russell has answers. And, unlike many of “the great philosophers”, his writing style is very clear and accessible.

    His ideas are simple and practical, yet practised by few. Rather than taking a “be happy with whatever you have” approach, he does argue that we should strive to find more happiness in some areas and ways—and lays out guidelines for doing so.

    Areas to expand, areas to pull back on, areas to walk a “virtuous mean”. Things to be optimistic about; things to not get our hopes up about.

    Applying Russell’s model, there’s no more “should I…?” moments of wondering which way to jump.

    Bottom line: if you’ve heard enough about “how to be happy” from wishy-washier sources, you might find the work of this famous logician refreshing.

  • Why You Can’t Skimp On Amino Acids

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Our body requires 20 amino acids (the building blocks of protein), 9 of which it can’t synthesize (thus called: “essential”) and absolutely must get from food. Normally, we get these amino acids from protein in our diet, and we can also supplement them by taking amino acid supplements if we wish.

    Specifically, we require (per kg of bodyweight) a daily average of:

    1. Histidine: 10 mg
    2. Isoleucine: 20 mg
    3. Leucine: 39 mg
    4. Lysine: 30 mg
    5. Methionine: 10.4 mg
    6. Phenylalanine*: 25 mg
    7. Threonine: 15 mg
    8. Tryptophan: 4 mg
    9. Valine: 26 mg

    *combined with the non-essential amino acid tyrosine

    Source: Protein and Amino Acid Requirements In Human Nutrition: WHO Technical Report

    Why this matters

    A lot of attention is given to protein, and making sure we get enough of it, especially as we get older, because the risk of sarcopenia (muscle mass loss) increases with age:

    Protein vs Sarcopenia

    However, not every protein comes with a complete set of essential amino acids, and/or have only trace amounts of of some amino acids, meaning that a dietary deficiency can arrive if one’s diet is too restrictive.

    And, if we become deficient in even just one amino acid, then bad things start to happen quite soon. We only have so much space, so we’re going to oversimplify here, but:

    1. Histidine: is needed to produce histamine (vital for immune responses, amongst other things), and is also important for maintaining the myelin sheaths on nerve cells.
    2. Isoleucine: is very involved in muscle metabolism and makes up the bulk of muscle tissue.
    3. Leucine: is critical for muscle synthesis and repair, as well as wound healing in general, and blood sugar regulation.
    4. Lysine: is also critical in muscle synthesis, as well as calcium absorption and hormone production, as well as making collagen.
    5. Methionine: is very important for energy metabolism, zinc absorption, and detoxification.
    6. Phenylalanine: is a necessary building block of a lot of neurotransmitters, as well as being a building block of some amino acids not listed here (i.e., the ones your body synthesizes, but can’t without phenylalanine).
    7. Threonine: is mostly about collagen and elastin production, and is also very important for your joints, as well as fat metabolism.
    8. Tryptophan: is the body’s primary precursor to serotonin, so good luck making the latter without the former.
    9. Valine: is mostly about muscle growth and regeneration.

    So there you see, the ill effects of deficiency can range from “muscle atrophy” to “brain stops working” and “bones fall apart” and more. In short, any essential amino acid deficiency not remedied will ultimately result in death; we literally become non-viable as organisms without these 9 things.

    What to do about it (the “life hack” part)

    Firstly, if you eat a lot of animal products, those are “complete” proteins, meaning that they contain all 9 essential amino acids in sensible quantities. The reason that all animal products have these, is because they are just as essential for the other animals as they are for us, so they, just like us, must consume (and thus contain) them.

    However, a lot of animal products come with other health risks:

    Do We Need Animal Products To Be Healthy? ← this covers which animal products are definitely very health-risky, and which are probably fine according to current best science

    …so many people may prefer to get more (or possibly all) dietary protein from plants.

    However, plants, unlike us, do not need to consume all 9 essential amino acids, and this may or may not contain them all.

    Soy is famously a “complete” protein insofar as it has all the amino acids we need.

    But what if you’re allergic to soy?

    Good news! Peas are also a “complete” protein and will do the job just fine. They’re also usually cheaper.

    Final note

    An oft-forgotten thing is that some other amino acids are “conditionally essential”, meaning that while we can technically synthesize them, sometimes we can’t synthesize enough and must get them from our diet.

    The conditions that trigger this “conditionally essential” status are usually such things as fighting a serious illness, recovering from a serious injury, or pregnancy—basically, things where your body has to work at 110% efficiency if it wants to get through it in one piece, and that extra 10% has to come from somewhere outside the body.

    Examples of commonly conditionally essential amino acids are arginine and glycine.

    Arginine is critical for a lot of cell-signalling processes as well as mitochondrial function, as well as being a precursor to other amino acids, including creatine.

    As for glycine?

  • Clean Needles Save Lives. In Some States, They Might Not Be Legal.

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Kim Botteicher hardly thinks of herself as a criminal.

    On the main floor of a former Catholic church in Bolivar, Pennsylvania, Botteicher runs a flower shop and cafe.

    In the former church’s basement, she also operates a nonprofit organization focused on helping people caught up in the drug epidemic get back on their feet.

    The nonprofit, FAVOR ~ Western PA, sits in a rural pocket of the Allegheny Mountains east of Pittsburgh. Her organization’s home county of Westmoreland has seen roughly 100 or more drug overdose deaths each year for the past several years, the majority involving fentanyl.

    Thousands more residents in the region have been touched by the scourge of addiction, which is where Botteicher comes in.

    She helps people find housing, jobs, and health care, and works with families by running support groups and explaining that substance use disorder is a disease, not a moral failing.

    But she has also talked publicly about how she has made sterile syringes available to people who use drugs.

    “When that person comes in the door,” she said, “if they are covered with abscesses because they have been using needles that are dirty, or they’ve been sharing needles — maybe they’ve got hep C — we see that as, ‘OK, this is our first step.’”

    Studies have identified public health benefits associated with syringe exchange services. The Centers for Disease Control and Prevention says these programs reduce HIV and hepatitis C infections, and that new users of the programs are more likely to enter drug treatment and more likely to stop using drugs than nonparticipants.

    This harm-reduction strategy is supported by leading health groups, such as the American Medical Association, the World Health Organization, and the International AIDS Society.

    But providing clean syringes could put Botteicher in legal danger. Under Pennsylvania law, it’s a misdemeanor to distribute drug paraphernalia. The state’s definition includes hypodermic syringes, needles, and other objects used for injecting banned drugs. Pennsylvania is one of 12 states that do not implicitly or explicitly authorize syringe services programs through statute or regulation, according to a 2023 analysis. A few of those states, but not Pennsylvania, either don’t have a state drug paraphernalia law or don’t include syringes in it.

    Those working on the front lines of the opioid epidemic, like Botteicher, say a reexamination of Pennsylvania’s law is long overdue.

    There’s an urgency to the issue as well: Billions of dollars have begun flowing into Pennsylvania and other states from legal settlements with companies over their role in the opioid epidemic, and syringe services are among the eligible interventions that could be supported by that money.

    The opioid settlements reached between drug companies and distributors and a coalition of state attorneys general included a list of recommendations for spending the money. Expanding syringe services is listed as one of the core strategies.

    But in Pennsylvania, where 5,158 people died from a drug overdose in 2022, the state’s drug paraphernalia law stands in the way.

    Concerns over Botteicher’s work with syringe services recently led Westmoreland County officials to cancel an allocation of $150,000 in opioid settlement funds they had previously approved for her organization. County Commissioner Douglas Chew defended the decision by saying the county “is very risk averse.”

    Botteicher said her organization had planned to use the money to hire additional recovery specialists, not on syringes. Supporters of syringe services point to the cancellation of funding as evidence of the need to change state law, especially given the recommendations of settlement documents.

    “It’s just a huge inconsistency,” said Zoe Soslow, who leads overdose prevention work in Pennsylvania for the public health organization Vital Strategies. “It’s causing a lot of confusion.”

    Though sterile syringes can be purchased from pharmacies without a prescription, handing out free ones to make drug use safer is generally considered illegal — or at least in a legal gray area — in most of the state. In Pennsylvania’s two largest cities, Philadelphia and Pittsburgh, officials have used local health powers to provide legal protection to people who operate syringe services programs.

    Even so, in Philadelphia, Mayor Cherelle Parker, who took office in January, has made it clear she opposes using opioid settlement money, or any city funds, to pay for the distribution of clean needles, The Philadelphia Inquirer has reported. Parker’s position signals a major shift in that city’s approach to the opioid epidemic.

    On the other side of the state, opioid settlement funds have had a big effect for Prevention Point Pittsburgh, a harm reduction organization. Allegheny County reported spending or committing $325,000 in settlement money as of the end of last year to support the organization’s work with sterile syringes and other supplies for safer drug use.

    “It was absolutely incredible to not have to fundraise every single dollar for the supplies that go out,” said Prevention Point’s executive director, Aaron Arnold. “It takes a lot of energy. It pulls away from actual delivery of services when you’re constantly having to find out, ‘Do we have enough money to even purchase the supplies that we want to distribute?’”

    In parts of Pennsylvania that lack these legal protections, people sometimes operate underground syringe programs.

    The Pennsylvania law banning drug paraphernalia was never intended to apply to syringe services, according to Scott Burris, director of the Center for Public Health Law Research at Temple University. But there have not been court cases in Pennsylvania to clarify the issue, and the failure of the legislature to act creates a chilling effect, he said.

    Carla Sofronski, executive director of the Pennsylvania Harm Reduction Network, said she was not aware of anyone having faced criminal charges for operating syringe services in the state, but she noted the threat hangs over people who do and that they are taking a “great risk.”

    In 2016, the CDC flagged three Pennsylvania counties — Cambria, Crawford, and Luzerne — among 220 counties nationwide in an assessment of communities potentially vulnerable to the rapid spread of HIV and to new or continuing high rates of hepatitis C infections among people who inject drugs.

    Kate Favata, a resident of Luzerne County, said she started using heroin in her late teens and wouldn’t be alive today if it weren’t for the support and community she found at a syringe services program in Philadelphia.

    “It kind of just made me feel like I was in a safe space. And I don’t really know if there was like a come-to-God moment or come-to-Jesus moment,” she said. “I just wanted better.”

    Favata is now in long-term recovery and works for a medication-assisted treatment program.

    At clinics in Cambria and Somerset Counties, Highlands Health provides free or low-cost medical care. Despite the legal risk, the organization has operated a syringe program for several years, while also testing patients for infectious diseases, distributing overdose reversal medication, and offering recovery options.

    Rosalie Danchanko, Highlands Health’s executive director, said she hopes opioid settlement money can eventually support her organization.

    “Why shouldn’t that wealth be spread around for all organizations that are working with people affected by the opioid problem?” she asked.

    In February, legislation to legalize syringe services in Pennsylvania was approved by a committee and has moved forward. The administration of Gov. Josh Shapiro, a Democrat, supports the legislation. But it faces an uncertain future in the full legislature, in which Democrats have a narrow majority in the House and Republicans control the Senate.

    One of the bill’s lead sponsors, state Rep. Jim Struzzi, hasn’t always supported syringe services. But the Republican from western Pennsylvania said that since his brother died from a drug overdose in 2014, he has come to better understand the nature of addiction.

    In the committee vote, nearly all of Struzzi’s Republican colleagues opposed the bill. State Rep. Paul Schemel said authorizing the “very instrumentality of abuse” crossed a line for him and “would be enabling an evil.”

    After the vote, Struzzi said he wanted to build more bipartisan support. He noted that some of his own skepticism about the programs eased only after he visited Prevention Point Pittsburgh and saw how workers do more than just hand out syringes. These types of programs connect people to resources — overdose reversal medication, wound care, substance use treatment — that can save lives and lead to recovery.

    “A lot of these people are … desperate. They’re alone. They’re afraid. And these programs bring them into someone who cares,” Struzzi said. “And that, to me, is a step in the right direction.”

    At her nonprofit in western Pennsylvania, Botteicher is hoping lawmakers take action.

    “If it’s something that’s going to help someone, then why is it illegal?” she said. “It just doesn’t make any sense to me.”
