Snap, Crackle & Pop: Why Do My Knees Make Noises - And Should I See a Doctor?
April 5, 2022
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 My Student Athlete's Pain More Than Just Growing Pains?
February 14, 2023
There are a few factors that can make student athletes prone to injury. They might be overusing their muscles (thanks to a more rigorous exercise regimen), and they might not yet have developed the proper technique for their sport.
“These factors, combined with the fact that student athletes have growing bodies that they’re still getting used to—especially after a growth spurt — can make them more prone to injury,” says Nancy White, M.D., a sports medicine physician with Henry Ford Health System.
However, just because your child is feeling pain doesn’t necessarily mean they’ve sustained an injury. There is such a thing as growing pains, although the term may be misleading. “Most experts feel that growth itself does not cause pain,” says Dr. White. “The most likely reason for ‘growing pains’ is overuse of the muscles, causing pain and soreness after an activity.”
These growing pains typically occur at the front of the thighs, the back of the knees and the calves, she says, and occur commonly in the late afternoon, evening, or night. If your child is experiencing pain outside of these areas or times of day, it might not be growing pains — and it’s a good idea to get it checked out by a doctor.
Tell-Tale Signs That Pain Should Be Examined
If the pain goes away by the next day — if your child has rested during night and feels better the next morning — there’s no need for concern. But you should head to the doctor if:
► the pain is lingering into the next day.
► the pain is also accompanied by bruising, swelling or redness.
► the pain is so intense that they’re unable to put weight on their legs.
“In these cases, don’t wait — the longer you wait, the more dangerous the injury can become,” says Dr. White.
How Student Athletes Can Help Prevent Injuries
Encourage your child to take proper precautions and maintain healthy habits, all of which can lower the likelihood that they’ll sustain an injury. Dr. White recommends the following tips:
- Maintain proper technique. “Knowing and understanding the movements needed for whatever sport they practice is so important,” says Dr. White. “Figure skating and gymnastics are two sports where I tend to see injuries more often during growth phases. These athletes are often learning difficult skills at a time in their lives when they’re going through a growth spurt, and that combination can lead to injury.”
- Stretch before and after playing a sport. “Try dynamic stretching — where you’re actually moving while stretching — instead of static stretching, where you’re holding the stretch,” says Dr. White. “Dynamic stretching is a great warm up. It can help improve flexibility and reduce the risk of injury.”
- Strength train, especially in the core and limbs. Doing so will help create stable, strong muscles to keep the body properly aligned and lessen the chances of injury.
- Eat a balanced diet and stay hydrated. While it’s normal for kids to have sugar every once in a while, filling the bulk of their diet with plenty of water, fresh fruits and vegetables, healthy protein, fats and carbohydrates will help them function to their best ability.
- Get enough rest each night. Sleep is necessary for health and well-being in general, but when it comes to athletes, rest is incredibly important to help their bodies recuperate. In general, kids need about 10 hours of sleep per night. So if your child plays a sport, you want to really be sure that they’re hitting that 10-hour mark, says Dr. White.
