Snap, Crackle & Pop: Why Do My Knees Make Noises - And Should I See a Doctor?

Do you ever just go about your daily life and then, seemingly out of nowhere, your knee makes a noise?

You might call it a weird idiosyncrasy and not think twice about it—or you might turn to the Internet to try and find all of the potential issues that might be wrong with your knee.

But if your knee pops or cracks once in a while, it’s usually no cause for concern. After all, joints sometimes make noises, and knees are no exception (especially when you squat or sit down.)

“Infrequent knee pops and cracks are more common in the younger population, says Nancy White, M.D., a sports medicine physician at Henry Ford Health. “When you feel that ‘pop,’ it means your kneecap was pulled a bit outside of where it’s supposed to be, and so it’s correcting itself and getting back into position. You can kind of feel that something moved.”

If, however, pain or swelling accompanies a noisy knee, you should have it evaluated by a sports medicine provider. And if your knee is popping or cracking regularly, that's another sign you should have it checked out. 

“If you let it go, your knee could get worse,” says Dr. White. “There are recommendations a doctor can make to prevent this from happening, such as strengthening and flexibility exercises.”

What Is Knee Crepitus?

If your knee sounds like Rice Krispies crackling (or you experience a grinding sensation) it likely means you have knee crepitus, which can signify the beginning of osteoarthritis behind the kneecap.

“Knee crepitus is primarily caused by an issue called patellofemoral dysfunction,” says Dr. White. That sounds like a mouthful, but it means that your knee isn’t tracking straight up and down like it’s supposed to.

“There’s cartilage on the back of your kneecap and on the front part of your thigh, and the cartilage on the front part of your thighbone makes a groove so the kneecap can glide straight up and down in a floating position,” says Dr. White. “If the cartilage is worn down (and inflamed, worn-down cartilage signifies osteoarthritis), the kneecap can’t smoothly glide up and down, causing knee crepitus.”

If you are experiencing knee crepitus, you should see a sports medicine primary care physician, especially if it is accompanied by pain. They can recommend a variety of treatments, such as physical therapy and cortisone injections.

Still not sure if your noisy knees are cause for concern? When in doubt, call your doctor. After all, the sooner your doctor can examine it, the sooner you can prevent an issue from getting worse.

How To Stay Hydrated: 7 Tips For An Active Summer

June 4, 2024

Not only is water an essential nutrient, it makes up your entire being. We’re 40 to 70 percent water, depending on fitness level and age. And while staying hydrated is always important, it may become more challenging as the weather heats up. Hard-working muscles generate more heat when they’re surrounded by hot air, making it harder for your body to maintain a normal temperature.

Henry Ford HealthEven a 1 to 2 percent loss of body weight from water can compromise your performance and impact your body’s ability to cool itself. The heart pumps harder, circulation slows and muscles fatigue more quickly. If the loss creeps up to 3 or 4 percent, you’ll be at increased risk of developing heat-related illness and injury, including cramps, heat exhaustion and heat stroke.

Even when you’re not active, your body loses more than a quart of water every day through urine, perspiration, sweat and breath, according to the National Institutes of Health. And most days, it’s more than 2.5 quarts.

The goal, of course, is to replace what’s lost. And with a little planning and preparation, you can during any outdoor activity, no matter what the thermometer says. Here’s how:

  • Drink before you’re thirsty. Need to quench your thirst? Chances are you’re already dehydrated. Your best defense against dehydration is drinking water on a consistent basis so you never reach the point of thirst.
  • Take frequent water breaks. While you might not want to disrupt your workout for a water break, taking time out for some much-needed liquid nourishment will pay off in the long run. Drink 8 to 10 ounces of water (about one full glass) before starting any activity. Once the games begin, drink another 7 to 10 ounces every 20 to 30 minutes.
  • Track your intake. Many people don’t know how much water they should drink daily—or even how much water they’re typically downing. If you’re sipping on a 16-ounce bottle, drink eight of them each day—and even more if you’re exercising heavily.
  • Consider an electrolyte drink. Working out for more than an hour? Consider sipping a sports drink—or nibbling on some pretzels or a banana to restore lost electrolytes (minerals in the blood that regulate bodily systems). Your body loses important electrolytes like sodium, potassium and chloride when you sweat. A good sports drink can help you replenish them. Coconut water is a great choice, but there are a slew of healthy, low-sugar options on the market.
  • Munch on water-rich produce. Water-packed snacks, including melon, berries, bell peppers and grapes, are all good options. A bonus: All of these foods boast a decent hit of electrolytes, too!
  • Step on the scale. Weigh yourself before and after a workout. If the scale shows a loss, replenish it with water (gulp 20 to 24 ounces of water for every pound lost). If you’ve lost 3 percent or more of your body weight, chances are you’re severely dehydrated.
  • Watch your urine stream. It may seem gross, but checking your pee is probably the best way to determine whether you’re dehydrated. If it looks like watered down, colored lemonade, you’re probably in the clear. But if it’s a deep yellow or light orange, you’re probably not drinking enough fluids.

Keep in mind that heat exhaustion happens quickly—especially during summer activities. It can easily turn into heat stroke, a dangerous condition that can lead to organ damage, seizures, coma and even death. If you feel dehydrated, dizzy or overheated, get out of the sun, sip some water (slowly) and apply cooling compresses to your head, neck and chest. If your symptoms don’t improve quickly, get to a doctor or call 9-1-1.
