Knee Pain When Running or Walking
Are you experiencing knee pain when walking or running? Here are several possible causes of knee pain and their treatments.
by Brad Chase
Knee pain is one of the most common types of pain that both men and women experience in their lifetime. According to the University of Alabama at Birmingham, as many as 2,000,000 patients will seek medical help for knee pain each year.
No matter your health, your fitness level, your race, or your gender, at some point or another it is very likely that you will experience knee pain.
When you experience knee pain when walking or knee pain when running, the pain itself can be worrisome. Your knees are constantly moving and experiencing pressure from your body weight, so when your knee pain appears to be making it more difficult to run or walk, it's easy to worry that something may be seriously wrong with your knees.
Before you concern yourself too much with your knee pain, it's important to remember that knee joints need time to heal like all other tissues in your body.
If you are running – or even walking – regularly, your knee joints may simply need a break. It's important not to ignore this pain and continue to run, especially if you have yet to consult a doctor. Sometimes knee pain is nothing more than your body telling you that it needs a rest. Listen to your body if you've been exercising too often, and give your joints time to heal.

While running is an important part of maintaining a healthy lifestyle, it does put a great deal of pressure on your knee joints. Each step pushes your bodyweight into your knees at a considerable force, all while your knees move your legs with each step.
That pressure can create small tears or lead to irritation that causes swelling. Long-term runners may find that they suffer from overuse injuries as well, which include bursitis and tendinitis.
Because of the amount of force that is exerted on the knee, injury can also be a problem. One misstep and all of your body weight forces the knee joints into a position it wasn't meant to twist. This can lead to some serious injuries including a tear of the anterior cruciate ligament (ACL), the medial collateral ligament (MCL), or the meniscus.
It's also possible to sprain the ligaments in your knee. Most sprains will heal on their own, but some sprains (Grade II sprains and Grade III sprains) may require surgery or physical therapy.
It's less common to experience significant knee pain when walking.
Previous injury, including sprains and tears, may cause knee pain while walking.
It's also possible to overwork the knee, either through repetitive motion or exercise. This can cause inflammation that may show up when you're walking and putting pressure on your knees.
Also, if you slept with your legs twisted in an uncomfortable position, you may also experience some knee pain while walking.
Mild knee pain can affect nearly anyone at any time. But when the knee pain is not caused by an injury and doesn't seem to go away on its own, it may be due to a long-term condition.
That condition is likely to be some form of arthritis – particularly osteoarthritis. Arthritis affects as many as 50,000,000 Americans according to the National Health Interview Survey, and it's estimated that half of all Americans will experience some form of arthritis by their 80's.
Osteoarthritis is characterized by inflammation in specific joints – especially joints that are consistently mobile, and may have received age-related damage over time. That inflammation leads to joint pain (in this case, knee pain) with swelling that may contribute to a lack of mobility.
This type of arthritis can be caused by a range of different factors, including:
Osteoarthritis generally starts mild, but can become worse over time if not treated with the right supplements. Osteoarthritis is not deadly, and those that suffer from arthritis are generally safe to walk, but may experience pain in the process.
Knee pain when running may be more pronounced, so it's a good idea to contact a doctor before taking up jogging to ensure you're clear to run.
Other arthritic conditions are known to affect the knees. Rheumatoid arthritis is an autoimmune disorder that attacks your joints. It generally affects your hands, feet, and knees at first, and the symptoms can be fairly mild. The disease may progress without treatment, however, and many of your joints may be affected.
Other potential conditions that create knee pain when walking or running include:
Very rare conditions like an osteosarcoma require a medical diagnosis and imaging scans.
Another condition that can contribute to knee pain when running and walking is referred to as referred hip pain. According to the Liverpool Department of Orthopedic Surgery at the University of Hospital Aintree, hip pathology (diseases of the hip) can also lead to knee pain, especially in the elderly.
Osteoporosis, for example, is a type of bonus disorder that can cause degeneration in the hips. Some studies have shown that this type of hip pain may lead to knee pain. If no clear cause of pain in the knee can be found, it may be useful to have your doctor check your hip as well.
Because there is such a wide variety of causes for aerobic knee pain, it's important to confirm an accurate diagnosis before you decide on a treatment.
Serious injury, cancer, bleeding disorders, or other rare knee problems will require a doctor's care. For more manageable diseases, care is as follows:
Interestingly, studies have shown that exercising once you feel you've recovered is an important part of preventing both temporary knee pain, overuse injuries, and potentially osteoarthritis, so make sure that you're taking the time to stay active. Consider athletic knee wraps as well, to keep your knee from experiencing further stress and injury when you exercise.
Supplementation is one of the better ways to treat osteoarthritis. Several nutrients are known to be effective at supplying the joints with minerals and nutrition that it needs to regain its strength and improve its regenerative powers.
But osteoarthritis is a degenerative disease, and when you have knee pain when running, you need to find a way to reduce the pressure you put on the joint each time you go out for a jog.
One of the best ways to do this is with osteoarthritis knee exercises – exercises that will reduce knee pain when walking or when running, and create an environment that puts less pressure on the joints. These include:
Calf stretches are designed to prevent injury. But they're also a good way to create additional strength around the knee.
Stand straight facing a wall. While you continue to face a wall, place one leg straight back and keep your foot flat against the ground. Place your other foot in front of you and bend at the knee slowly. With your back foot pressed against the ground, place weight on that leg so that your calf feels like its stretching. Hold for 20 seconds, then repeat with the other leg.
Another useful leg exercise takes place while lying down. Lay back on something comfortable, like your bed or a couch. Bend one leg and bring it towards you, then take your other leg (keeping it straight) and raise it up to about 30 to 45 degrees above the bed. Hold for 5 to 10 seconds, then repeat with the other leg. Do roughly 10 sets of each, depending on strength level.
It's highly recommended that you consider aquatic exercise for the more advanced stages of osteoarthritis. When the pain of arthritis keeps you from exercise, the lighter weight in a pool reduces the pressure.
According to research at the Parker Institute by Drs. Else Marie Bartels and Hans Lund, aquatic exercise appears to be beneficial for short term improvements in osteoarthritis pain – an important step for reducing knee pain when walking.
One example looks like you're doing an underwater "Can Can." While standing in chest deep water, lift one knee upwards. Once it's entirely raised, kick your leg out and upwards, using your leg muscles. Bring your leg back down and repeat with your other leg.
Knee pain when running – and to a lesser extent, knee pain when walking – can be a normal occurrence. While there are some diseases that can cause these conditions, some degree of pain should be expected.
However, because of how important your knees are to movement and how fragile they can be, it's important to manage your pain and make smart decisions about how you handle your knee health.
If it's simply some minor pain from running regularly or mild overuse, try to keep pressure off the knee while it heals. Ice packs and knee braces can be useful as well.
Osteoarthritis takes a bit more management. Osteoarthritis is also known as "degenerative joint disease" because the condition can worsen over time. Strengthening your leg muscles can be a big help. Also, make sure you're taking some type of osteoarthritis supplement to nourish your joints and keep them from degenerating further.
If the condition is more chronic and something more serious, like a tear to a ligament, contact your doctor and see what treatment they recommend. Surgery or physical therapy may be necessary to keep your knee from experiencing further damage.
