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.

Is Your Teen Sleep-Deprived?

Many teens tend to stay up late. They’re on social media, watching television or YouTube, studying, or just tossing and turning for hours unable to fall asleep. Sleep can also be disrupted during stressful times during adolescence like exams or relationship problems.

More than two-thirds of high school students in the U.S. are failing to get sufficient sleep on school nights, according to a recent study from the Centers for Disease Control and Prevention (CDC).

“The American Academy of Sleep Medicine (AASM) recommends that teens should sleep eight to 10 hours per night on a regular basis to promote optimal health,” explains Virginia Skiba, M.D., a sleep specialist with the Henry Ford Health System. Insufficient sleep can have a negative impact on their grades, athletic performance and mental and physical well-being, including depression and anxiety issues and drug and alcohol use.

It’s a safety issue, as well. Motor vehicle crashes are a leading cause of teen deaths in the U.S. In a recent survey, more than half of teens admitted to having driven when feeling too tired and nearly one in 10 teens reported having fallen asleep at the wheel.

A typical high school student is biologically wired to fall asleep around 11 p.m. Many high schools in Michigan start school as early as 7 a.m. – long before a teen’s natural wake time. The AASM advocates a later middle school and high school start time of 8:30 a.m. or later.

Tips for a Good Night’s Sleep

Teenagers’ sleep-wake cycles are biologically determined – they are programmed to stay up late at night and sleep later in the morning. Most teens are instinctively night owls. Falling asleep is often a challenge, but there are things teens can do that may help them get a good night’s sleep.

Here are some tips from Dr. Skiba, which apply not only to teens but are great advice for anyone who is struggling with feeling sleep deprived:

► First and foremost, make sleep a priority. In our busy society, too often making time for sleep is last on the list.

► Maintain a consistent bedtime and wake time that allows at least eight hours of nightly sleep, including on weekends and vacation.

► Keep the bedroom quiet and dark. Keep the TV, computer, phone and video game system out of the bedroom.

► Set a technology curfew; turn off all devices one hour before bedtime.

► Engage in quiet activities before bed, like reading, journaling or yoga, and establish a relaxing bedtime ritual.
