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.

Add Rest Days to Your Workout Routine

Whether you're new to exercise or a seasoned enthusiast, it's tempting to adopt an all-go, no-quit attitude. This is especially common when you're are trying to achieve a fitness goal. Maybe you want to run a 5K, or maybe you have 10 pounds you want to shed before going on vacation.
"Whatever the driver, it's important to remember that scheduling time for rest and rejuvenation is a critical component of any workout regimen," says James Moeller, M.D., a sports medicine specialist at Henry Ford Health System.
Building in Rest Days
From high-intensity interval training (HIIT) and spin to barre and Zumba, popular workouts increasingly push exercisers to go faster, longer, stronger. This prolonged physical stress can lead to overuse injuries, such as stress fractures, muscle strains and joint pain. Excessive exercise can also lead to hormonal changes, disrupted sleep patterns, decreased immunity and mood swings.
“Working out, especially resistance training, breaks tissues down, causing microscopic damage,” Dr. Moeller says. "Rest days allow your muscles time to rebuild."
So how much rest do you really need? There isn't a one-size-fits-all prescription. Factors like your age, fitness level, the intensity of your workout and the amount of training you do weekly will impact the amount of recovery time you need. But there are some basic guidelines for rest days:
1. Go easy: Rest is a relative term. "It's not just sitting on the couch with an iced tea," says Dr. Moeller. "You may still be exercising on 'rest' days, but at a lower intensity." Maybe you go for a brisk walk or ride your bike to work. Take a yoga class or do some dynamic stretching. The key is to make sure you're not overworking the same body parts.
2. Get sufficient sleep: Sleep is a key component of muscle repair and rebuilding. During sleep, your body’s production of growth hormone increases. Not getting quality shuteye thwarts your body's production of growth hormone and can impact your performance.
3. Give overtaxed muscles a break: You don't need to skip the gym on specific days each week, but you do need to rotate which body parts you're working. The general rule is to give muscles 48 hours to recover after a workout. So it's a good idea to take two to three days off before working the same muscle groups again.
4. Stay hydrated: Make sure to restore lost fluids before, during and after a workout. Dehydration can lead to overheating, headaches and muscle fatigue, among other ailments. You don’t need a sports drink; water is best. "Sports drinks aren't required unless you're getting into very high intensity activity, or exercising for more than one hour at a time," Dr. Moeller says.
5. Pay attention to your body: A lot of people try to work out through pain and fatigue. If there's a heaviness to your movements, or if you feel like your muscles are not responding appropriately to the stress you're providing, take a time out. "It's really about learning to read your body's signals," says Dr. Moeller.
Health authorities and news headlines widely publicize the health benefits of exercise — and the consequences of inactivity. The American Heart Association recommends that adults get at least 150 minutes of moderate-intensity exercise per week, plus strength training two or three days per week. Less discussed are the negative effects of not allowing your body sufficient time to rest.
Getting sufficient rest between workouts is just as important as participating in regular exercise. "Both are part of the total process required to build strength, endurance and muscle mass," Dr. Moeller says.
