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 Strategies To Improve Range Of Motion
March 6, 2024
When it comes to health and fitness, regular exercise and strength training get the most attention. But it turns out that improving your range of motion may pay greater dividends, particularly over the long haul.
“All kinds of things can impact our range of motion,” says Jennifer Burnham, an athletic trainer at Henry Ford Health. “As we age, our joints become less pliable, but any kind of surgery or injury can also impact our range of motion. And if you're somebody who sits at a desk all day long, that can affect your range of motion as well.”
Why Is Improving Flexibility Important?
Staying active with regular cardiovascular exercise and strength training is a great way to maintain your overall physical health. But it’s important to remember that flexibility exercises come with plenty of perks, too, including:
- Preventing injury
- Staving off arthritis by lubricating joints and tissues
- Improving posture and balance
"Unfortunately, if you have limited range of motion, you may perform tasks incorrectly, causing other muscles and joints to overcompensate for the lack of mobility,” Burnham says. “Over time, that compensation mechanism can increase the risk of injury.”
To complicate matters, our lifestyles often don’t support our range of motion goals. Many of us spend most of our days sitting at a desk or hunched over a screen. And when we’re not sitting still, most of us are slouching.
What Are Some Ways To Improve Range Of Motion?
You don’t have to be able to twist your limbs into a pretzel to achieve full range of motion. Instead, try to improve on your current level of flexibility with these five simple strategies:
- Pay attention to timing. If you’re not ready to add a stretching day to your workout regimen, consider adding a set of flexibility exercises at the end of every session. Pre-workout stretching is helpful, too, but stretching when your muscles are warm is a more effective way to stave off injuries.
- Focus on mobility and stability. Even if you can do the splits or touch your toes to the back of your head, you won’t be able to hold the position if you don’t also have strong core muscles. “Most people do stabilizing exercises such as strength training and lifting weights without paying much attention to mobilizing activities like stretching and yoga,” Burnham says. “But you really need to do both stabilizing and flexibility exercises to get an effective workout.”
- Do a mix of dynamic and static stretches. Two types of stretches can help you gain an edge when it comes to improving range of motion: Dynamic (an active type of stretching where you’re moving within your range of motion) and static stretching (where you hold a stretch). Dynamic stretching with arm and head circles, side stretches, and hip circles before exercise is a good way to warm up cool muscles and help lubricate the joints. With static stretching such as touching your toes to stretch your hamstrings, the goal is to hold a position for 30 seconds or more. Static stretches are often best performed after a workout when your muscles are warm.
- Try foam rolling. Foam rollers act almost like a rolling pin to smooth out tight muscles. Used correctly, they can help improve range of motion — and release stress and tension. You can use foam rollers to prime your body for exercise, or to recover after a workout.
- Aim for balance. If one part of your body is super flexible, focus on increasing range of motion in the opposing muscle group. “So, for example, if your hamstrings are very flexible, make sure to target your quadriceps with flexibility exercises,” Burnham says. “The goal is to make sure you’re aiming for balancing in your body.”
While stretching is an important way to achieve and maintain balance, flexibility and range of motion, it isn’t always intuitive. Not sure where to begin? Consider meeting with a personal trainer or athletic trainer to help you devise a program.
“Watching YouTube videos can be helpful, but if you’ve never done flexibility exercises before, you could overstretch your muscles or find yourself in an incorrect position to stretch,” Burnham says. “And yes, you can create bodily injury by overstretching.”
