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.

Start Planning Now for a Thriving Spring Garden
Winter offers an ideal time to plan for a successful spring garden. Assess your current space, research planting ideas, and design an efficient layout. Enhance soil health with compost, start seeds indoors for stronger plants, and organize tools to ensure readiness for the growing season. Prepare now for a thriving garden.

Start Planning Now for a Thriving Spring Garden
(Family Features) While winter weather puts outdoor gardening on pause in most parts of the country, the colder months offer a perfect opportunity to begin preparing for a lush garden come springtime.
With a little creativity, and some extra time spent creating a plan, you can set yourself on a path toward success before the growing season even begins.
Assess Your Space and Research Ideas
Evaluate your current garden, taking note of what worked well last season and where improvements can be made. Use this downtime to sketch an updated layout, research companion plants and decide which fruits, vegetables or flowers you want to grow next based on what did (or didn’t) work last spring.
Build an Updated Blueprint
Winter is the ideal time to upgrade your garden design and make tweaks for efficiency. Use the offseason to consider crop rotation patterns for optimal soil health as well as ways to maximize your space such as raised beds, trellises or containers. You can also make a list of materials needed for any new features you may be adding, such as an irrigation system, and map out their placement so you’re ready to build as soon as the weather allows.
Nourish the Soil
Even if the ground is frozen, you can prepare your garden beds by adding compost, leaves or organic matter in late winter, ensuring nutrients are available when spring arrives. Also remember to test your soil’s pH level now, which can help guide your fertilization plan.
Start Seeds Indoors
If you’re eager to get your hands dirty, consider starting your seeds indoors. Early seed starting gives plants a head start, allowing you to transplant stronger seedlings outdoors when temperatures warm.
Get Organized
Use the slower pace of winter to clean and sharpen your garden tools, sort through leftover seeds and make a supply checklist so you’re ready to dig in when warmer days arrive.

‘Pawty’ Tips for Celebrating Your Pets
People spent $147 billion on pets last year. Dog birthday parties are trending. Tips: spacious play areas, engaging activities, personalized details, insect control, themed snacks, and friendly guest lists.
Last Updated on March 11, 2026 by Daily News Staff
(Family Features) It’s no secret – people love their pets. Last year alone, people spent $147 billion on their pets, according to the American Pet Products Association, which included throwing what has turned into one of the hottest invites on social media these days: pet parties. There have been more than 1 million posts using #DogBirthday to show off these celebrations.
With dog birthday parties and adoptions being celebrated across the country, entertainment ideas can be borrowed from regular parties – but the special guests will need to be taken into account when planning a party designed for pooches.
Plan a pup party with these tips from Mindy Weiss, a best-selling author and event planner for notable celebrity clients.
Plan for a Place to Play
When hosting a dog party, make sure there is plenty of space for the pups to play, whether it’s a fenced yard or a large indoor area. The more room they have to zoom around, the happier (and safer) everyone will be.
Keep the dogs entertained with activities like a ball pit, kiddie pool or basket of tennis balls. If you’re feeling ambitious, hide treats around the yard for the dogs to find. It’s a great way to keep their tails wagging and their minds engaged while they have a blast.
Personalize Party Details
Subtle accents can elevate any party. Pick a theme that can come to life through the decor and details, such as a “retro dog disco,” where both the humans and dogs can dress up. Small touches like personalized dog tags or themed water bowls and dog treats can make any pet party a memorable event.
Avoid Party Crashers
When guests and dogs are moving indoors and out, alongside (often messy) food, flying insects will likely try to sneak their way in. That’s why no party is complete without this top pet party essential – the STEM Attracts and Traps Flying Insects Light Trap. It is people- and pet-friendly when used as directed, insecticide-free and uses a soft UV light to attract flying insects with a dual-sided, refillable cartridge to trap them. It can also be used throughout the home in kitchens, garages, around pet feeding stations and more.
Remember the Pup Parents
Don’t forget about the humans. While the dogs are the guests of honor, the humans might also enjoy a nibble. Consider staying on theme with mini hot dogs, bone-shaped pretzels or “pup pop” cake pops.
Bring on the Besties
Just like humans have best friends, dogs do too. Before sending out invites, make sure the guest list includes dogs that are friendly with your pup and play well with others. A little pre-party check can help ensure everyone has a good time.
