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.

Can A Sports Physical Replace A Wellness Exam?

August 8, 2023

Before your child can take the field or hit the courts, their doctor must give the all-clear for them to play.

Henry Ford HealthSince the sports physical is a pre-requisite to organized activity, you may be tempted to skip your child’s annual well-visit. After all, do you really need to go to the doctor’s office twice if they’re healthy enough to play sports?

Of course, the answer is yes! Each type of visit to your pediatrician serves a different purpose, and one cannot replace the other.

Shoshana Gordon, D.O., a pediatrician for Henry Ford Health, explains the differences between the sports physical and regular wellness examination.

What Happens at a Wellness Exam

An annual wellness exam is a comprehensive visit that allows your child’s pediatrician to monitor all aspects of your child’s development. These appointments can vary quite a bit, depending on your child’s age.

“Your child grows so much early in life that we need to see them several times before their first birthday,” says Dr. Gordon. “As they get older, the conversations at these appointments evolve and expand to include topics like mental health and what to expect from puberty.”

Generally, many aspects of your child’s wellness exam will stay the same over time. Regardless of age, this appointment will include:

  • Checking vitals (heart rate, blood pressure)
  • A physical exam (to monitor physical growth)
  • Discussing developmental milestones
  • Developmental and emotional/behavioral screenings
  • Conversations about nutrition and any physical activities your child is involved in
  • Conversations about how your child is getting on at school
  • An opportunity to discuss questions or concerns you or your child may have

One crucial part of the wellness exam is immunization. This appointment is the best time for you to talk with your child’s pediatrician to make sure that your child is up to date on necessary vaccines.

Additionally, wellness exams are the best way for you and your child to develop a relationship with their pediatrician. When you only take your child to the doctor when they are sick, it is harder for your pediatrician to set a baseline for their health.

“Regular wellness visits allow you and your child to get comfortable with asking your doctor questions,” says Dr. Gordon. “Once we develop a good patient-provider relationship, your child’s pediatrician will have an easier time recognizing when your child isn’t feeling like themselves and can better offer alternate approaches to care that best suit your child’s unique needs."

What Happens at a Sports Physical

Sports physicals are used to determine if your child is healthy enough to participate in organized sports. During this appointment, your child’s doctor will screen them for different sports-specific health concerns. They will be evaluating several things including:

  • Heart function
  • Lung function
  • Mobility
  • Reflexes
  • Endurance

“During a sports physical, we’ll look at both your child’s and your family’s health history to make sure there aren’t any indicators that could impact your child’s ability to play,” says Dr. Gordon. “For example, if your child had COVID or if you have a family history of cardiovascular complications, additional tests may be necessary to make sure this isn’t affecting your child’s health.”

The biggest difference from a wellness exam? Sports physicals don’t include developmental screeners that are essential to your child’s growth.

“At the end of the day, a sports physical cannot take the place of your child’s annual wellness exam,” says Dr. Gordon. “However, when you go for your child’s wellness exam, talk to your child’s pediatrician about including a sports physical as part of the appointment.”

In addition to the developmental, social and emotional evaluations that take place at your child’s annual wellness exam, this is the best time for you and your child to get to know your pediatrician. Establishing yourself with your child’s doctor will make it easier to treat and care for your child as they continue to grow.
