Why Do My Knees Pop All The Time

Osteoarthritis Of The Knee

Why do my joints crack all the time?

If crepitus occurs with pain, this can be an early sign of osteoarthritis of the knee. OA is normally a result of wear and tear, and it tends to develop and worsen with age.

In OA, the cartilage that covers the ends of bones in the joints gradually wears away. Bones rub on this increasingly rough surface, resulting in pain and mobility issues. It is more likely among people with obesity or those who have had an injury in the past.

A study published in the journal Osteoarthritis and Cartilage found that women aged 45 to 60 years who had both crepitus and patellofemoral pain had a 72 percent chance of developing OA, although they did not yet have a diagnosis of OA.

The Centers for Disease Control and Prevention estimate that of adults aged 65 years and above were living with a diagnosis of arthritis between 2013 and 2015.

Tips and treatment

If a person has an early diagnosis of OA, the Osteoarthritis Foundation suggest using nonsurgical options to slow the progression, maximize mobility, and improve strength.

Options include:

  • lifestyle modifications, such as weight loss and exercise
  • medication

As OA progresses, treatment through medication or even knee replacement surgery may be necessary.

When To Seek Medical Help

Although a popping joint can be startling, there is generally nothing that needs to be done . In some cases, popping can occur as part of a degenerative disorder that makes the joint susceptible to these and other sounds.

Unless it is accompanied by more concerning symptoms such as pain and swelling, you should not worry. However, cracking noises, which often sound like popping, can be a sign of problems that need treatment, like gout, inflammation, and joint dislocation.

When To Tell Your Doctor About Joint Popping

If you are experiencing joint popping, even if it seems excess, it is only a problem if you are feeling pain as a result. Painful joint popping can be a symptom of early stage arthritis, tendinitis, or bursitis. Arthritis is, of course, characterized by inflammation of a joint, which can cause painful popping as the bones of the joint begin to rub together. Note that, again, this is not caused by knuckle cracking, and has nothing to do with the buildup of gas in the joint. However, the two in tandem can lead to pain and discomfort. Tendinitis is an inflammation of a tendon, which can cause the joint to move in awkward ways, thus causing the joint to pop. Bursitis is the more likely case, though the pain it causes should be nearly ever present. Bursitis is caused by inflammation of the bursa, which helps to lubricate joints. When the bursitis is injured, joints are more likely to rub together, thus causing popping, creaking, cracking, and pain.

The bottom line is this: joint popping is not a problem in the long term, unless its a problem in the short term. If you arent experiencing pain, you can crack your knuckles all day long the worst you have to fear is weird looks from your friends.

Symptoms & Signs Of Crepitus

Crepitus, or joint sounds, can be a normal part of movement. Many people experience popping joints, especially as they get older. You may notice:

  • Popping or cracking when you bend your knee or elbow
  • Crunching sounds in your knee when you go up or down stairs or kneel
  • Crackling or grinding sounds or a crunching sensation when you move your shoulder
  • Occasional or continual swelling around the joint

Causes Of Crepitus Or Joint Sounds

Why are my joints cracking all of a sudden ...

Often, crepitus is harmless. It happens when air seeps into the soft tissues around the joint . When you bend the joint, the air bubbles burst, and you hear a cracking sound.

While most crepitus is harmless, some forms of crepitus signal a problem. If the popping or crunching sound comes with pain, you should see a doctor to evaluate the cause.

Causes of painful joint popping may include:

  • Osteoarthritis: Arthritis is a condition in which cartilage begins to rub away, leaving bones unprotected and creating inflammation. When bones rub and grind, it causes pain and stiffness that usually gets worse with activity. Read more about arthritis.
  • Patellofemoral pain syndrome : Also known as runners knee, PFS causes crepitus along with pain behind the kneecap . It can happen when you suddenly increase your activity level and is often caused by running, squatting or jumping. PFS is more common in women than in men. Learn more about knee pain.
  • Torn cartilage: A cartilage tear can happen because of a sports injury, a fall or an accident. Cartilage damage is another possible cause of painful crepitus. Find out more about cartilage damage.

What The Clicking Is Not

Many of our patients worry that the clicking represents the bones rubbing together and causing damage to the joints. This is simply not the case. It is normal for knees to click, they are moving parts with many structures that move and glide next to each other when you bend and straighten the knee, for example when going up or down the stairs.

Knee Pain And Popping

Reviewed by: KPE Medical Review Board

Knee pain and popping is a common problem. It’s that tell-tale snap, crackle, pop making your knees sound like a bowl of rice krispies.

Many people find they hear strange noises such as knee clicking when they do things such a squatting down or getting up from kneeling.

In many cases, it is more of a nuisance than a real problem, but in some cases, it may be a sign of an underlying problem in the knee.

Knee popping in itself is very common and can be caused by a number of things. It may be as simple as little bubbles of gas popping in the knee or indicate a problem in the soft tissues such as a ligament tear.

Another term commonly used for popping in the knee is “crepitus”, which essentially means a noisy joint, whether it be popping, clicking, cracking or snapping.

Here we look at the most common causes of knee pain and popping and how to treat them.

A Look At The Knee Joint

The knee works like a large hinge. It consists of bones, cartilage, the synovium, and ligaments.

Bones: The knee joins the thighbone to the long bone of the lower leg . The fibula, a bone in the lower leg, is also connected to the joint. The kneecap is the small, convex bone that sits at the front of the knee, shielding the joint.

Cartilage: Two thick pads of cartilage called the menisci cushion the tibia and femur, and reduce friction where they meet.

Synovium: A specialized connective tissue that lines joints and tendon sheaths. Synovial fluid serves to lubricate the joints.

Ligaments: Four ligaments tough, flexible bands that stretch across the uneven surface of the joints connect the bones.

Crepitus happens for various reasons, apart from osteoarthritis. Here are some of them:

Symptoms Of Cracking Knees

The main symptoms that cause concern are a cracking or popping when the knee hits its full range of motion.

For most people, this is completely harmless: it happens as a natural result of aging. As the cartilage on the joint starts to wear, it becomes uneven in certain places.

What you hear could be the rough spots moving over one another, or the tissue that connects bones together tightening, or even just air bubbles popping from a change in joint pressure. All in all, nothing to worry about.

Pain Associated With Joint Grinding

If your joint noise is accompanied by pain or swelling, you may want to consider speaking to your orthopedic specialist. The most common reasons for knee pain include:

Meniscus tear

Your meniscus is the rubbery disc that cushions your knee and absorbs pressure and shock. If you twist your knee unexpectedly, such as when you move the joint but your foot stays still, you can tear your meniscus.

Cartilage Injury

Your knee is situated just in front of your femur, and if your cartilage begins to rub this area, you may feel some discomfort. When your cartilage wears off or is damaged, it can hang around your knee joint and irritate the surrounding area. Sitting for an extended period of time, climbing, walking, or squatting can become painful.

Why Do My Knees Crack

Neck Cracking and Grinding: What Does It Mean?

UABs Harsvardhan Singh, Ph.D., says typically, there is no concern if there is no pain associated with knee cracks.You might have heard this sound before: the loud pop or crack of someone elses or your own knees. Sometimes it can be an unpleasant experience, but one researcher at the University of Alabama at Birmingham says typically, there is no need for concern.

What does it mean that my knees crack?

Knee cracking could mean lots of things, said Harshvardhan Singh, Ph.D., assistant professor with UABs Department of Physical Therapy. If it is painful, then you should see a health care provider.

Singh adds that a painless knee crack could come from multiple sources:

  • A large-sized kneecap that does not fit well into the groove, thus producing a cracking sound during activities such as running and jogging.
  • If the thigh muscle is too tight, it can pull the kneecap and affect its free gliding movement, generating a knee crack.
  • If the various soft tissues such as cartilage or meniscus have degenerated, resulting in loss of smooth cover of the knee joint, and leading to knee cracks during various activities.

The degenerative changes can also lead to pain and/or locking of the knee joint, he said. Typically, degenerative changes are common in older people, so a degenerative change-associated knee crack may be found commonly in older people.

Is Your Joint Popping A Sign Of Something Bigger

Joint popping is a pretty normal occurrence youve surely experienced it. You move your ankle and hear a faint pop, or wring your hand together and enjoy the relief as your knuckles crack in quick succession. For the most point, joints cracking and popping isnt a problem. There are rare cases where it can be a sign of a hard to see problem, though. Many people dont understand why joints pop and crack, either, which can lead to some confusion about the experience. The phenomenon is actually more interesting than you might think, and could be important to know about.

Possible Causes Of A Knee Pop

Some associate a knee pop with solely one condition, when actually this can point to a number of knee conditions. Below is a list of possible causes and a few knee conditions in which the afflicted might hear or feel a knee pop:

  • Crepitus: Crepitus describes the popping, grating, or creaking sensations and sounds within the joint. A buildup of gas bubbles in the surrounding areas of the joint and the sudden release of the gas may cause these noises. While crepitus is typically painless and of no concern, any accompanying symptoms such as swelling or discomfort indicate the affected person should take precautionary measures and see a specialist.

  • Meniscal tear: The combined symptoms of a pop in the knee and swelling are associated with a meniscal tear. Some patients, however, may not experience these symptoms after a certain amount of time of inactivity but still have a tear.

  • Knee arthritis: Several types of arthritis can form in the knee, such as osteoarthritis or inflammatory arthritis. Because general symptoms of these conditions include stiffness, swelling, and instability of the knee joint, the knee may pop as a result.

  • Ligament injuries: The four ligaments that stabilize the knee are the anterior cruciate posterior cruciate medial collateral and the lateral collateral An impact injury or abrupt tear in any of these ligaments may cause the knee to pop, depending on the circumstances of the injury.

Reasons Not To Worry About Your Clicking Knees:

  • There is no evidence it will get worse as you get older
  • There is no evidence it will wear out your joint and cause osteoarthritis
  • Painfree clicking is unlikely to stop you from carrying out the activities you love doing, be it hiking, running, cycling, squatting or gardening!
  • There is no correlation between the amount of clicking or the volume of the clicking and levels of pain.
  • There is no evidence it will progress into becoming painful. It is not a pain predictor!
  • Many of our physiotherapists are dual trained as musculoskeletal sonographers. This means they use diagnostic ultrasound as part of their clinical assessment to look inside the body to assess the joint and surrounding soft tissue structures such as ligaments and tendons.

    Diagnostic ultrasound is a dynamic imaging technique. Unlike static imaging techniques such as an X-ray or MRI, ultrasound can assess the structures whilst the patient can carry out a specific movement that reproduces the click. This makes it the perfect assessment to accurately identify the structures that are causing the clicking and the specific reason for your pain.

    Knee Pain And Popping Causes

    Knee popping and clicking can be caused by a number of things. It may be something simple like the ligaments catching on a bony lump and “snapping” back in to place or gas bubbles popping. But in some cases, knee popping is linked to a more serious injury such as ligament or cartilage tear.

    Knee clicking and popping noises in the knee usually fall into one of three categories:

  • Pain-Free Popping Knee: Popping noises in the knee often occur without any pain, in which case they are nothing to worry about
  • Painful Popping Noise at time of Injury: Sometimes when the knee is injured e.g. twisting awkwardly, there is a sudden, loud “pop” at the same time indicating damage to part of the knee
  • Recurrent Painful Popping Noises not Caused by an Injury: Knee pain and popping can come on gradually with no obvious cause. It may happen sporadically or frequently depending on the cause.
  • Side Steps With Resistance Band

    The outer quad muscle tends to be weaker than the muscle that runs along the top of your thigh, which leads to the kind of imbalance that causes your kneecap to pull out of line. The solution? Strengthen that outer muscle, says Butts.

    How to do it:

  • Pull a medium resistance band up right below your knees and lower down into a squat .
  • Move two steps to the right then two steps to the left, working hard to pull your legs apart and stretch the band.
  • Repeat one 30-second to 1-minute set three times.

    When To See A Doctor

    If you have any pain along with these symptoms, have a doctor look at your knee as soon as possible. Doing so may prevent a more serious knee injury including anterior cruciate ligament injuries. They affect between 100,000 and 200,000 Americans each year.

    Even if the knee popping isn’t painful, you may still want to have it checked out. In some cases, it may be an early warning sign of an overuse injury. This may require weight loss, a change of footwear, or knee-strengthening exercises to protect the joint.

    The best treatments are targeted directly at the specific problem that is causing the abnormal popping or snapping inside the knee joint. You can ease crepitus and tendon problems with treatments to reduce inflammation in the knee joint, such as rest and anti-inflammatory medications.

    Most mechanical problems are best treated with arthroscopic knee surgery. This is a procedure in which a camera and tools are passed through small incisions into the joint to repair any damage.
