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.

5 Tips to Prevent Sports-Related Injuries

Participating in sports provides so many benefits to kids and teens. There are the obvious benefits of physical fitness and promoting regular exercise. Then, there are also the character-building lessons learned from being part of a team, working hard toward a goal, celebrating tough competition and gracefully accepting defeat. But sports don’t come without some risk.
Sports-related injuries are the leading cause of emergency room visits for kids ages 12-17, according to the Centers for Disease Control and Prevention (CDC).
These injuries impact twice as many males as females. Not surprisingly, contact sports also have higher injury rates. Football, basketball, baseball and soccer account for roughly 80 percent of all sports-related emergency room visits for children.
Sports injuries depend on the age of the athlete and the type of sport played, according to Bridget McArdle, D.O., a Henry Ford pediatrician. Generally, she says, sports injuries are divided into two groups: injuries from overuse like strains and tendonitis, and acute injuries such as concussions, fractures and tears.
The teen years pose special hazards, too. The adolescent growth spurt places teens at higher risk for injuries.
“The growth plates could still be open, which increases the risk for damage,” Dr. McArdle says. “This can lead to long-term problems.”
5 Important Injury Prevention Tips
Fortunately, many sports-related injuries can be prevented — the CDC estimates that as many as half of them could be avoided.
Here are Dr. McArdle’s tips for injury prevention for parents and coaches:
1. Ease into training. It’s important to start gradually in order to decrease the chance of sports injuries. “When you train too quickly at full peak, you are more likely to get hurt. Ease into it – and don’t overdo it,” says Dr. McArdle.
2. Cross train. Changing up the way your child trains is one way to help prevent sports injuries. “Taking a break from one sport to play another is important,” she recommends. Training a different way and using different muscles decreases the strain placed on the same body parts. Practicing gentle stretching exercises such as yoga or Pilates can also help, she adds.
3. Use the right equipment. Everything from the proper shoes and appropriate, properly fitted safety gear for the particular sport are essential for minimizing the risk of injury, as well.
4. Avoid excessive heat. The American Academy of Pediatrics (AAP) recommends young athletes avoid heat illness by wearing light clothing and drinking plenty of fluids before, during and after exercise or play. Coaches should decrease or stop practices during high heat or high humidity periods.
5. Take time to recover. If a sports injury does occur, taking time to recover is very important. Returning to play too soon increases the risk of making the injury worse, and increases the chance of long-term consequences. “Make sure the injury is completely healed before returning. Don’t allow your child to play through pain,” advises Dr. McArdle.
If you have questions or concerns about your child’s readiness to play, be sure to get a sports physical and talk with your pediatrician or primary care provider.
