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.

How To Be Proactive About Concussions In Student Athletes
December 5, 2023
Most people have seen the headlines about concussions as a common sports injury—and it's natural that parents of athletes may have concerns. A large misconception in sports is that previous concussions are to be blamed for ongoing headaches, blurred vision and memory loss, among other symptoms.
“It’s really important to think about concussions in tandem with overall brain health,” says Jake Carpenter-Thompson, M.D., Ph.D., a board-certified neurologist at the Henry Ford Kutcher Clinic for Concussion and Sports Neurology. “Concussions can be concerning, but they shouldn’t be looked at in a vacuum. It is important to understand an athlete’s overall brain health to help manage recovery after any impact.”
One way to do that is to consult with your child’s doctor or a sports neurologist for an annual evaluation. A sports neurologist focuses on managing sports-related brain and nervous system injuries and conditions in athletes, such as concussions, post-concussion syndrome, peripheral nerve injuries, migraines, epilepsy and more.
“Having an annual evaluation of your athlete’s brain health when they are at their baseline – and uninjured – can help diagnose and treat issues when they arise,” says Dr. Carpenter-Thompson.
A qualified healthcare professional can use the baseline evaluation results as an important comparison tool if an athlete develops a suspected concussion.
Best Practices For Keeping Athletes Safe
Dr. Carpenter-Thompson shares these tips to ensure you keep front of mind your child’s brain health and safety, not just their athletic performance:
- Get a brain health baseline test. This should include a personal and family neurological history, with a focus on current issues. It is important to note any neurological conditions that may influence concussion recovery, such as ADHD, depression, anxiety or migraine headaches.
- Encourage your children to listen to their body. There are risks to playing any sport. Encourage your child to listen to and be honest about how they’re feeling. It’s the best way to prevent and treat injuries.
- In the event of an injury, look for the signs. Within 24 hours after an injury, an athlete should be evaluated if they are experiencing: headaches, fatigue, dizziness and nausea, changes in sleep habits, trouble with memory, confusion, irritability and anxiety, or light sensitivity.
- Know that brain injuries don’t just occur with a blow to the head. They can also occur from falls, car accidents or even whiplash. If your child is experiencing any symptoms, consult your physician.
- Remember that brain health is more than just concussions. If your athlete is complaining of chronic headaches, migraines, dizziness, memory or mood issues, there may be an underlying issue.
“There is no magic number of concussions a brain can sustain. Each person is different,” says Dr. Carpenter-Thompson. “The severity of the impact and recovery time can vary greatly for numerous reasons. By getting a brain health assessment before the injury, we can provide more targeted care to improve an athlete's overall clinical course.”
