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.

Stretching Done Right: Easy Tips To Stay Limber

Stretching is more than just a workout suggestion – it's a vital way to avoid injury and get the most out of your activity. You wouldn’t take your car on a long drive without making sure it’s in tip-top shape, right? So before you work up a sweat, work up a stretch.
One important thing to keep in mind is that dynamic stretching is best. It uses momentum to propel your muscles into an extended range of motion. Unlike static stretching, where you remain in an almost still position, a dynamic warm up is the best way to get your blood flowing and your heart rate pumping.
To get your muscles primed for activity, high knees, "butt kicks" and side shuffling are more effective than standing quad stretches. If you are doing an upright quad stretch, it's best to lean back a little to get the full benefit, since your quads originate from above the hip. Also, remember to always grab the ankle and not the toe.
Here are some other helpful hints on how to warm up the right way:
- For hamstrings: The hamstring muscle attaches to your bones below the knee at the back of the leg, so you want to avoid bending them (which ultimately shortens the muscle you’re trying to stretch). When bending at your back, make sure to keep your spine straight like a table to elongate those muscles. Keep your chin up. If you bend down to touch your toes, there’s no need to hover closer than six inches above the ground – unless you’re able to comfortably do so.
- For pectoral muscles: "Door stretches” offer the best stretch. Simply place your arms out on either side of you as if you were making a “T” with your body. Then, bend your arms up at your elbows so they each form a 90-degree angle. In this position, put your arms on either side of a door frame, with your body within the frame’s opening and walk forward slowly to open up the chest.
- For triceps: Make a gesture like you’re scratching your upper back and be sure to keep your elbows in for maximum benefit.
- For the torso: The iron cross stretch involves putting your arms out at your sides like a “T” and then rotating at your waist side to side. You can also drop down toward the floor and reach for your toes, one side at a time.
Other great tips to add to your stretching repertoire include:
- Don’t forget to keep breathing throughout your stretch. It will help keep your muscle tissue oxygenated.
- Hold each stretch for 10 to 20 seconds, aiming for three repetitions of each. If you prefer, you can split up your stretching throughout the day, or use props like foam rollers to help ease tension in your muscles and break up knots.
- Listen to your body while stretching. Slight pain is acceptable, but if your muscles start shaking, it's a warning for you to stop.
- Don't give up. Stretching progress can be slow, so comparing your progress to that of others will only discourage you. Pay attention to your own progress. Seeing your body become more flexible when you previously weren’t limber will help keep you motivated and is the ultimate reward.
