Treatment options to help overcome knee pain for sports enthusiasts
“Sports-related pain should be evaluated quickly, especially when it’s difficult to put weight on the knee, swelling occurs or there is restricted range of motion,” said Dr. Alexander Meininger, orthopedic surgeon and MACI consultant.
Millions of people experience chronic pain, with knee pain among the most common. Athletes and active adults know the impact activities like running and skiing can have on their knees, but when chronic knee pain makes it difficult to do those activities, or even day-to-day tasks like walking up the stairs, people may often face challenges.
According to the journal “Cartilage,” unlike other tissues, cartilage does not repair itself and, without proper treatment, can worsen over time and become more difficult to treat. However, options like FDA-approved knee cartilage repair surgery MACI (autologous cultured chondrocytes on porcine collagen membrane) uses a patient’s cells to help repair cartilage defects and may help alleviate knee pain.
“Sports-related pain should be evaluated quickly, especially when it’s difficult to put weight on the knee, swelling occurs or there is restricted range of motion,” said Dr. Alexander Meininger, orthopedic surgeon and MACI consultant.
Justin Keys, a former patient of Meininger and avid skier, knows that the long-term outcomes of knee cartilage surgery can be worth the short-term sacrifices. After several injuries, including an ACL injury, Keys struggled with most activities except walking on flat, paved surfaces. After consulting with Meininger, Keys chose knee cartilage repair to help get back to his active lifestyle.
Keys considered whether to manage the injury as-is or choose MACI and undergo rehabilitation to potentially get back to his favorite activities in the future. He knew he could no longer use short-term relief methods and had to address his pain with a treatment to help provide lasting relief.
For athletes like Keys who want to fix knee pain, it’s important to consider these steps:
Discuss Options with Your Doctor
Patients should talk to their doctors and undergo an MRI to help assess the internal structures of the knee. Meininger recommends patients and their doctors discuss options for long-term knee restoration health, preserving function for future decades and recognizing the short-term sacrifice.
Set Yourself Up for Success
Experts like Meininger suggest patients take steps ahead of surgery to help their recovery.
“The important thing is to be as fit as possible and use the preseason months to undergo surgery and rehab,” Meininger said.
Patients can take steps to prep their home for recovery, which may include:
- Bringing necessities down from hard-to-reach shelves
- Moving furniture to ensure clear pathways
- Installing shower safety handles to minimize potential falls
The Road to Rehab and Recovery
Rehabilitation takes time and everyone’s experience is unique. It can be as much of a mental challenge as it is physical. Committing to a physical therapy regime, staying hydrated and eating well are important aspects to support recovery. Patients should talk to their doctors with questions and before starting any exercises.
IMPORTANT SAFETY INFORMATION
Do not use if you are allergic to antibiotics such as gentamicin or materials from cow or pig; have severe osteoarthritis of the knee, other severe inflammatory conditions, infections or inflammation in the bone joint and other surrounding tissue or blood clotting conditions; had knee surgery in the past 6 months, not including surgery for obtaining a cartilage biopsy or a surgical procedure to prepare your knee for a MACI implant; or cannot follow a rehabilitation program post-surgery.

Keep Dirt and Germs Away
The more active you are, the harder it can be to find a bandage that stays with you all day or all game long.
Spray Away Sore Spots
Controlling mild pain can help keep you at the top of your game, and a topical analgesic works fast to heal common pain brought on by fitness and exercise, such as pain in knees, feet, shoulders and backs.
Put Pain in the Past
When recovery becomes the name of the game and pain relief is needed after daily workouts or bodily injuries. Cold packs work to heal bruises, reduce swelling and relieve headaches and general pain points while microwavable heat packs provide satisfying heat therapy to address sore and stiff joints, muscle cramps and tension.
Reduce Impact of Knee Strain
Weak, injured or arthritic knees can come from many sources, including tendonitis and a wide range of conditions that result in strain or overuse. An adjustable band can provide support for on-field sports and during workouts or everyday activities.
Manage Pain and Relieve Pressure
If you participate in endurance and strength exercises or certain sports, you may ask a lot of your joints. Kinesiology tape can be configured a multitude of ways to help reduce pain and improve blood circulation, as well as relieve tension and pressure.
Control Back Strain
When your back is strained, your body and performance can suffer. A mild or moderate sprain can benefit from strong support and compression.

Exercise can provide relief for dry, itchy eyes
A significant increase in tear secretion and tear film stability after participating in aerobic exercise can be another remedy for relieving dry, itchy eyes.
A team led by researchers from the University of Waterloo discovered that a significant increase in tear secretion and tear film stability after participating in aerobic exercise can be another remedy for relieving dry, itchy eyes.
Every time we blink, our eyes are covered in tear film—an essential protective coating necessary for maintaining healthy ocular function. Healthy tear film comprises three layers–oil, water, and mucin–that work together to hydrate the ocular surface and protect against infection-causing irritants like dust or dirt.
When any part of the tear film becomes unstable, the ocular surface can develop dry spots, causing eye symptoms like itchiness or stinging and burning sensations.
“With so much of our activity tied to screen usage, dry eye symptoms are becoming increasingly common,” said Heinz Otchere, a PhD candidate in vision science at Waterloo. “Instead of having to use eye drops or other alternative treatments, our study aimed to determine if remaining physically active can be an effective preventative measure against dryness.”
Fifty-two participants were divided into two groups—athlete and non-athlete—to participate in an exercise session. Participants in the athlete group exercised at least five times per week, while non-athlete participants exercised no more than once per week. Researchers, which included experts from the University of Cape Coast in Ghana, performed visual examinations before and five minutes after each exercise session, where tear secretion and tear break-up time were assessed.
While participants in the athlete group showed the largest increase, Otchere says all participants experienced a meaningful boost in tear quantity and tear film stability after the exercise session.
“It can be challenging for people to regularly exercise when the demand is there to work increasingly longer hours in front of screens,” Otchere said. “However, our findings show physical activity can be really important for not just our overall well-being, but for our ocular health too.”
The study, Differential effect of maximal incremental treadmill exercise on tear secretion and tear film stability in athletes and non-athletes, was co-authored by Otchere, the University of Cape Coast’s Samuel Abokyi, Sekyere Nyamaah, and Michael Ntodie, and Ghana’s Our Lady of Grace Hospital’s Yaw Osei Akoto. It was recently published in the Experimental Eye Research journal.

Late-life exercise shows rejuvenating effects on cellular level
Late-life exercise mitigates skeletal muscle epigenetic aging.
For people who hate exercising, here comes some more bad news: it may also keep you younger. Not just looking younger, but actually younger, on an epigenetic level. By now, the benefits of exercise have been well established, including increased strength of bones and muscles, improved mobility and endurance, and lower risk of heart disease, diabetes and high blood pressure.
But younger?
A study recently published in Aging Cell, “Late-life exercise mitigates skeletal muscle epigenetic aging,” suggests this could be the case. The paper was written by a team of seven researchers across three institutions, including Kevin Murach, an assistant professor in the Department of Health, Human Performance and Recreation at the U of A. Murach’s grant from the National Institute of Health funded the study, and he was one of three co-first authors.
Bootcamp for Mice
While the paper is dense with data, reflecting the use of several analytic tools, the experiment that generated the data was relatively straightforward. Lab mice nearing the end of their natural lifespan, at 22 months, were allowed access to a weighted exercise wheel. Generally, mice require no coercion to run and will do so voluntarily. Older mice will run anywhere from six to eight kilometers a day, mostly in spurts, while younger mice may run up to 10-12 kilometers. The weighted wheel ensured they built muscle. While there isn’t a direct analogue to most human exercise routines, Murach likened it to “a soldier carrying a heavy backpack many miles.”
When the mice were studied after two months of progressive weighted wheel running, it was determined that they were the epigenetic age of mice eight weeks younger than sedentary mice of the same age — 24 months. Murach noted that while the specific strain of mice and their housing conditions can impact lifespans, “historically, they start dropping off after 24 months at a significant rate.” Needless to say, when your lifespan is measured in months, an extra eight weeks — roughly 10 percent of that lifespan — is a noteworthy gain.
Methylation, My Dear Watson
The science behind this, while complicated, hinges largely on a biological process known as DNA methylation. A recent New York Times article discussing Murach’s work on muscle memory described methylation “as a process in which clusters of atoms, called methyl groups, attach themselves to the outside of genes like minuscule barnacles, making the genes more or less likely to turn on and produce particular proteins.”
As the body ages, there tends to be increased DNA methylation, or even hypermethylation, at promoter sites on genes in muscle. “DNA methylation changes in a lifespan tend to happen in a somewhat systematic fashion,” Murach explained, “to the point you can look at someone’s DNA from a given tissue sample and with a fair degree of accuracy predict their chronological age.” Due to this, researchers can use one of a number of “methylation clocks” to determine the age of a DNA sample.
DNA Methylation, Aging and Exercise
While the paper strengthens the case for exercise, there is still much that needs to be learned. Though the connection between methylation and aging is clear, the connection between methylation and muscle function is less clear. Murach is not yet prepared to say that the reversal of methylation with exercise is causative for improved muscle health. “That’s not what the study was set up to do,” he explained. However, he intends to pursue future studies to determine if “changes in methylation result in altered muscle function.”
“If so, what are the consequences of this?” he continued. “Do changes on these very specific methylation sites have an actual phenotype that emerges from that? Is it what’s causing aging or is it just associated with it? Is it just something that happens in concert with a variety of other things that are happening during the aging process? So that’s what we don’t know.”
