Knee problems tend to flare up as you age – an orthopedic specialist explains available treatment options
Angie Brown, Quinnipiac University
Knee injuries are common in athletes, accounting for 41% of all athletic injuries. But knee injuries aren’t limited to competitive athletes. In our everyday lives, an accident or a quick movement in the wrong direction can injure the knee and require medical treatment. A quarter of the adult population worldwide experiences knee pain each year
As a physical therapist and board-certified orthopedic specialist, I help patients of all ages with knee injuries and degenerative conditions.
Your knees have a huge impact on your mobility and overall quality of life, so it’s important to prevent knee problems whenever possible and address pain in these joints with appropriate treatments.
Healthy knees
The knee joint bones consist of the femur, tibia and patella. As in all healthy joints, smooth cartilage covers the surfaces of the bones, forming the joints and allowing for controlled movement.
Muscles, ligaments and tendons further support the knee joint. The anterior cruciate ligament, commonly known as the ACL, and posterior cruciate ligament, or PCL, provide internal stability to the knee. In addition, two tough pieces of fibrocartilage, called menisci, lie inside the joint, providing further stability and shock absorption.
All these structures work together to enable the knee to move smoothly and painlessly throughout everyday movement, whether bending to pick up the family cat or going for a run.
Causes of knee pain
Two major causes of knee pain are acute injury and osteoarthritis.
Ligaments such as the ACL and PCL can be stressed and torn when a shear force occurs between the femur and tibia. ACL injuries often occur when athletes land awkwardly on the knee or quickly pivot on a planted foot. Depending on the severity of the injury, these patients may undergo physical therapy, or they may require surgery for repair or replacement.
PCL injuries are less common. They occur when the tibia experiences a posterior or backward force. This type of injury is common in car accidents when the knee hits the dashboard, or when patients fall forward when walking up stairs.
The menisci can also experience degeneration and tearing from shear and rotary forces, especially during weight-bearing activities. These types of injuries often require rehabilitation through physical therapy or surgery.
Knee pain can also result from injury or overuse of the muscles and tendons surrounding the knee, including the quadriceps, hamstrings and patella tendon.
Both injuries to and overuse of the knee can lead to degenerative changes in the joint surfaces, known as osteoarthritis. Osteoarthritis is a progressive disease that can lead to pain, swelling and stiffness. This disease affects the knees of over 300 million people worldwide, most often those 50 years of age and up. American adults have a 40% chance of developing osteoarthritis that affects their daily lives, with the knee being the most commonly affected joint.
Age is also a factor in knee pain. The structure and function of your joints change as you age. Cartilage starts to break down, your body produces less synovial fluid to lubricate your joints, and muscle strength and flexibility decrease. This can lead to painful, restricted movement in the joint.
Risk factors for knee problems
There are some risk factors for knee osteoarthritis that you cannot control, such as genetics, age, sex and your history of prior injuries.
Fortunately, there are several risk factors you can control that can predispose you to knee pain and osteoarthritis specifically. The first is excessive weight. Based on studies between 2017 and 2020, nearly 42% of all adult Americans are obese. This obesity is a significant risk factor for diabetes and osteoarthritis and can also play a role in other knee injuries.
A lack of physical activity is another risk, with 1 in 5 U.S. adults reporting that they’re inactive outside of work duties. This can result in less muscular support for the knee and more pressure on the joint itself.
An inflammatory diet also adds to the risk of knee pain from osteoarthritis. Research shows that the average American diet, often high in sugar and fat and low in fiber, can lead to changes to the gut microbiome that contribute to osteoarthritis pain and inflammation.
Preventing knee pain
Increasing physical activity is one of the key elements to preventing knee pain. Often physical therapy intervention for patients with knee osteoarthritis focuses on strengthening the knee to decrease pain and support the joint during movement.
The U.S. Department of Health and Human Services recommends that adults spend at least 150 to 300 minutes per week on moderate-intensity, or 75 to 150 minutes per week on vigorous-intensity aerobic physical activity. These guidelines do not change for adults who already have osteoarthritis, although their exercise may require less weight-bearing activities, such as swimming, biking or walking.
The agency also recommends that all adults do some form of resistance training at least two or more days a week. Adults with knee osteoarthritis particularly benefit from quadriceps-strengthening exercises, such as straight leg raises.
Treatments for knee pain
Conservative treatment of knee pain includes anti-inflammatory and pain medications and physical therapy.
Medical treatment for knee osteoarthritis may include cortisone injections to decrease inflammation or hyaluronic acid injections, which help lubricate the joint. The relief from these interventions is often temporary, as they do not stop the progression of the disease. But they can delay the need for surgery by one to three years on average, depending on the number of injections.
Physical therapy is generally a longer-lasting treatment option for knee pain. Physical therapy treatment leads to more sustained pain reduction and functional improvements when compared with cortisone injections treatment and some meniscal repairs.
Surgical interventions for knee pain include the repair, replacement or removal of the ACL, PCL, menisci or cartilage. When more conservative approaches fail, patients with osteoarthritis may benefit from a partial or total knee replacement to allow more pain-free movement. In these procedures, one or both sides of the knee joint are replaced by either plastic or metal components. Afterward, patients attend physical therapy to aid in the return of range of motion.
Although there are risks with any surgery, most patients who undergo knee replacement benefit from decreased pain and increased function, with 90% of all replacements lasting more than 15 years. But not all patients are candidates for such surgeries, as a successful outcome depends on the patient’s overall health and well-being.
New treatments on the horizon
New developments for knee osteoarthritis are focused on less invasive therapies. Recently, the U.S. Food and Drug Administration approved a new implant that acts as a shock absorber. This requires a much simpler procedure than a total knee replacement.
Other promising interventions include knee embolization, a procedure in which tiny particles are injected into the arteries near the knee to decrease blood flow to the area and reduce inflammation near the joint. Researchers are also looking into injectable solutions derived from human bodies, such as plasma-rich protein and fat cells, to decrease inflammation and pain from osteoarthritis. Human stem cells and their growth factors also show potential in treating knee osteoarthritis by potentially improving muscle atrophy and repairing cartilage.
Further research is needed on these novel interventions. However, any intervention that holds promise to stop or delay osteoarthritis is certainly encouraging for the millions of people afflicted with this disease.

Daylight saving time and early school start times cost billions in lost productivity and health care expenses
Daylight saving time disrupts sleep, leading to increased heart attacks, accidents, and mental health issues. Advocating for permanent standard time and later school start times could significantly enhance public health and reduce economic costs.
Joanna Fong-Isariyawongse, University of Pittsburgh
Investigations into the 1986 Space Shuttle Challenger disaster revealed that key decision-makers worked on little sleep, raising concerns that fatigue impaired their judgment. Similarly, in 1989, the Exxon Valdez oil spill resulted in a massive environmental catastrophe. The official investigation revealed the third mate, in charge of steering the ship, was running on too little sleep, among other problems.
While these specific disasters were not caused by daylight saving time, they are conclusively linked to fatigue, based on postaccident investigations and reports. They underscore the well-documented dangers of sleep deprivation and fatigue-related errors. Yet a vast body of research shows that every year, the shift to daylight saving time needlessly exacerbates these risks, disrupting millions of Americans’ sleep and increasing the likelihood of accidents, health issues and fatal errors.
Imagine a world where one simple decision – keeping our clocks aligned with the natural cycle of the Sun – could save lives, prevent accidents and improve mental well-being. It’s not just about an hour of lost sleep; it’s about how small disruptions ripple through our health, our workplaces and even our children’s futures.
I’m a neurologist who specializes in sleep health. I’ve seen firsthand the negative impacts of poor sleep; it has enormous personal and economic consequences.
Yet despite overwhelming research supporting better sleep policies – such as delaying school start times to align with adolescent biology and the adoption of permanent standard time – these issues remain largely overlooked in public policy discussions.
Sleep deprivation comes with real costs
Chronic sleep deprivation does more than leave people tired. It costs an estimated US$411 billion annually in lost productivity and health care costs. Poor sleep leads to workplace mistakes, car accidents and long-term health issues that strain businesses, families and the economy as a whole.
Fortunately, there’s a fix. Smarter sleep policies – such as permanent standard time and later school start times – can boost efficiency, improve health and save lives.
Up before dawn
Teenagers are the most sleep-deprived age group in the U.S. Multiple studies and surveys show that anywhere from 71% to 84% of high school students report getting insufficient sleep.
This is largely due to early school start times, which force teens to wake up before their biological clocks are ready. If you have a teenager, you probably see it every day: The teen struggling to wake up before sunrise, rushing out the door without breakfast, then waiting in the dark for the school bus.
More than 80% of public middle and high schools in the U.S. start before 8:30 a.m., with 42% starting before 8 a.m. and 10% before 7:30 a.m. As a result, some districts have bus pickups as early as 5 a.m.
Teenagers are going through a natural shift in their circadian rhythms by about two hours. This shift, driven by hormones and biology, makes it hard for them to fall asleep before around 11 p.m. The bodies of teens aren’t wired for these schedules, yet schools and society have designed a system that forces them to function at their worst.
Declining scores, drowsy driving and depression
Sleep-deprived teens have lower grades and test scores, more car crashes caused by drowsy driving, more alcohol and drug use and higher rates of depression, anxiety suicide and aggressive behavior, including carrying weapons.
Along with the health benefits, studies have found that moving school start times to 8:30 am or later could add $8.6 billion to the economy within two years, partly by increased graduation rates.
While concerns about increased transportation costs exist, such as the need for additional buses or drivers due to staggered school start times, some districts have found that optimizing bus routes can offset expenses, making the change cost-neutral or even cost-saving. For instance, a study in Boston found that reorganizing bus schedules using advanced algorithms reduced the number of buses needed and improved efficiency, which allowed high school students to start later and better align with their natural sleep cycles. This change not only supported adolescent sleep health but also saved the district $5 million annually. https://www.youtube.com/embed/OR6il9otpqM?wmode=transparent&start=0 Studies show that daylight saving time does not reduce energy use.
More heart attacks, car wrecks and suicide
Every March, most Americans shift their clocks forward for daylight saving time. Studies show this change disrupts sleep and leads to measurable adverse outcomes, including a significant increase in heart attacks. These effects linger for days after the shift, as sleep-deprived workers struggle to adjust.
The mental health impact is also severe. Suicide rates increase in the weeks following the switch, particularly for those already vulnerable to depression.
Unlike daylight saving time, standard time follows the body’s natural circadian rhythm, which is primarily regulated by exposure to sunlight. Our internal clocks are most stable when morning light exposure occurs early in the day, signaling the body to wake up and regulate key biological functions such as hormone production, alertness and metabolism. In contrast, daylight saving time artificially extends evening light, delaying the body’s release of melatonin and making it harder to fall asleep at a biologically appropriate time.
Studies have found that adopting permanent standard time could prevent up to 5,000 suicides annually by reducing seasonal depression, decrease errors, injuries and absenteeism in the workplace and make roads safer, potentially preventing 1,300 traffic deaths each year.
Times are changing
The U.S. tried permanent daylight saving time in 1974. It was so unpopular that Congress repealed it within nine months.
Russia tried it too, in 2011, but switched back three years later. The United Kingdom dropped permanent daylight saving time in 1971 after three years, and Portugal in 1996 after four. All of these countries found that the switch caused widespread public dissatisfaction, health concerns, more morning car accidents and disrupted work schedules. No country is currently on year-round daylight saving time.
These examples provide real-world evidence that permanent DST is undesirable due to public dissatisfaction, safety concerns and negative health effects – all three countries attempted it and ultimately reversed course. Since 2022, there has been renewed debate, largely driven by former U.S. Sen. Marco Rubio’s Sunshine Protection Act, which aims to make DST permanent.
However, the name is misleading because it doesn’t “protect” sunshine but rather eliminates critical morning light, which is essential for regulating circadian rhythms. Major health organizations, along with the National Safety Council, strongly oppose permanent DST due to its well-documented risks.
There are signs that suggest the U.S. is finally waking up to these problems. Out of 13,000 school districts, 1,000 have independently adopted later school start times. California and Florida have enacted laws requiring high schools to start no earlier than 8:30 a.m. California’s mandate went into effect in 2022, and Florida’s is set to begin in 2026.
Permanent standard time and later school start times are not radical ideas. They’re practical, evidence-based solutions based on human biology. Implementing these changes nationally would require congressional action. However, current federal law already allows states to adopt permanent standard time, as Arizona and Hawaii have done, setting a precedent for the rest of the country.
