Crepitus Answers The Question On What Causes Knees To Pop

The lubrication secreted for your knees, called synovial fluid, allows your bones and ligaments to glide against each other for smoother movements. However, this fluid can form some bubbles, which is what causes knees to pop without co-occurring with pain. This condition called crepitus is also natural and evident in other areas of your body.

The kind of crepitus thats accompanied by pain is a sign of an underlying knee condition, which can either be mild or serious. Knee popping, in this case, could mean friction aggravated by the inflammation of the sac that produces lubrication or the wearing of your cartilage due to overuse. These conditions vary and can include arthritis, bursitis, tendinitis, patellofemoral pain syndrome or meniscus tears, to name a few problems that can bring about certain knee conditions.

Crepitus can also be a result of an underlying injury or resurgence of the symptoms of a previous injury that wasnt treated. You may have had a tear in one of your major ligaments , or your cartilage which a recent fall have exposed and aggravated.

What Is Patellar Tracking Disorder

Patellar tracking disorder means that the kneecap shifts out of place as the leg bends or straightens. In most cases, the kneecap shifts too far toward the outside of the leg. In a few people, it shifts toward the inside.

Your knee joint is a complex hinge that joins the two bones of the lower leg with the thigh bone.

  • The kneecap sits in a groove at the end of the thigh bone. It is held in place by tendons on the top and bottom and by ligaments on the sides.
  • A layer of cartilage lines the underside of the kneecap. This helps it glide along the groove in the thigh bone.

A problem with any of these parts in or around the knee can lead to patellar tracking disorder.

Why Do My Knees Crack

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.

Should I be worried if my knees crack often or loudly?

Can Knee Cracking Lead To An Injury

Knee Pain Caused By Damage In Knee Joint Shown Using ...

As discussed above, Knee Cracking is nothing but the synovial fluid producing the sound.1 There is no involvement of the bones or ligaments and hence there is no chance of an injury to the ankles. The only exception to this being people who have a known diagnosis of arthritis of the knee joint or an unstable knee which has a tendency to frequently dislocate. An individual with these conditions comes off a long plane ride or hikes for a significant distance can experience Knee Cracking along with pain. Apart from this, there is no data to suggest that Knee Cracking can result in any form of injury to the knee joint.

Thus, it is recommended for people who have a history of arthritis of the knees or have a weak joint which is prone to frequent dislocations to avoid sitting for prolonged periods of time, squat, walk or hike for long distances without resting for some time so as not to injure the knee.

Crepitus Following Surgery Or Trauma

published in Clinics in Orthopedic Surgery shows that up to 18 percent of people who have a total knee arthroplasty , or knee replacement, will experience crepitus. This may due to the design and fit of the new knee.

This type of crepitus usually resolves without intervention.

However, if problems persist, a doctor may recommend debridement, a minor surgical procedure to remove debris from around the joint.

Another reason for crepitus after surgery is arthofibrosis, or the development of scar tissue. This can lead to pain and stiffness in the joint. It can also happen after a traumatic injury.

If the person experiences pain and stiffness after an injury or surgery, they should see a doctor. The doctor may recommend monitoring the knee, and it may need treatment.

Often, however, crepitus that follows an injury or surgery is not serious. Doctors , for some people, the crepitus may have been there before, but an increased awareness how the joint is reacting makes it more noticeable now.

Often, say the researchers, reassurance and rehabilitation are enough.

Treatment may not be necessary. If it is, the options will depend on the cause, as outlined above.

If crepitus occurs with exercise, the person should not stop exercising but modify the exercise.

Precautionary measures include:

When exercising, people should always listen to their body. If there is pain, they should stop. Always exercise in moderation and stretch before exercising.

Other ways to protect the knees include:

How to Fix Knee Snapping and Pop Sounds

The precise onset of physiological noise is commonly unknown by patients. On the contrary, the onset of pathological noise is relatively clear compared to physiological noise. The onset of pathological noise can be divided into acute and chronic. Acute onset of noise accompanied by pain may be caused by meniscal or ligament injury., Chronic pathological noise can occur gradually it may occur sporadically or frequently, depending on the cause. Recurrent and chronic noise may be caused by old meniscal tears, cartilage injury, OA, patellofemoral instability, or patellofemoral pain syndrome.,,,

Most of the time these noises are natural and do not mean that you will develop arthritis or be prone to injury. Knee clicking and popping are extremely common during the first year after any knee surgery. These are usually due to soft tissue swelling or early scar formation.

Most Common Knee Instability Causes

The most common causes of knee instability include the following.

  • Ligament sprain: Sprain of the knee ligaments, which means these ligaments have had their fibers damaged due to wear and tear, sudden stress, or direct trauma.
  • Ligament tear: Tear of the ligaments, meaning the fibers have been partially or completely torn through. This usually happens when you run and then make a sudden change of direction the knee stays pointing one way while the rest of you twists the other way.

What Is Causing That Clicking Sound In Your Knee

Knee Popping

Clickingknees often leads to anxiety which can limit your ability to enjoy certainphysical activities. Noise in the knee joint can come from several different reasons.

Natural Noises of the Knee

  • Harmless Joint Popping As you move your knee around, air pockets build up within the knee joint fluid. Sometimes, when you perform a movement, the change in pressure causes those air pockets to pop and create a snapping sound called cavitation.
  • Soft tissue rubbing over a bone The knee is surrounded by ligaments and tendons so sometimes these tissues catch over a bony bump and make a noise.

These noises are natural and are usually nothing to be concerned about.

Possible Conditions to be Concerned About?

Torn Meniscus Ifthe clicking in your knee comes with pain and it feels like something iscatching within the knee when you try to bend or straighten it, you may have ameniscus tear.

When the meniscus gets damaged fromoveruse or trauma, loose pieces of cartilage can catch within the knee.

Osteoarthritis Ifyou hear painful popping and grinding, it may be from Osteoarthritis. This iswhen the cartilage in the knee joint has worn away and it may be bone on bone.This condition is typically very painful.

The Most Common Causes Of Knee Popping And Snapping:

  • Anterior cruciate ligament tears. ACL tears are a serious knee injury. ACL tears often occur as a non-contact injury. Most often a player is turning or pivoting and they felt a pop. Soon after the knee will swell and it will be hard to walk. You should be evaluated if you had an injury and your knee popped. Some people are walking around with chronic ACL tears. They didnt realize they had a severe injury, and eventually, when the swelling went away, they returned to playing soccer or lacrosse. Now, every time they pivot or go to change direction their knee pops. Thats because the knee is unstable. Torn ACL
  • Chondromalacia: This is a condition where the cartilage under your kneecap is starting to soften, and occasionally develop cracks and some loose pieces. As the cartilage degenerates the surface can become rough. That rough surface will rub against the femur and cause snapping, clicking, or popping. Most cases of chondromalacia do not require surgery. Often times the pain and popping on the front of the knee will subside over time. Now that might take a few months. Physical therapy is often very effective in treating pain in the front of the knee.

How Is It Treated

Patellar tracking disorder can be a frustrating problem, but be patient. Most people feel better after a few months of treatment. As a rule, the longer you have had this problem, the longer it will take to get better.

Treatment of patellar tracking disorder has two goals: to reduce your pain and to strengthen the muscles around your kneecap to help it stay in place. If you dont have severe pain or other signs of a dislocated kneecap, you can try home treatment for a week or two to see if it will reduce your pain.

  • Take a break from activities that cause knee pain, like squatting, kneeling, running, and jumping.
  • Put ice on your knee, especially before and after activity. After 2 or 3 days, you can try heat to see if that helps.
  • Take an over-the-counter pain reliever such as ibuprofen or naproxen to reduce pain and swelling. Read and follow all instructions on the label.

As your knee pain starts to decrease, do exercises to increase strength and flexibility in your leg and hip. Your doctor or a physiotherapist can help you plan an exercise program that fits your condition. You will probably start with one or two exercises and add others over time. Make sure to closely follow the instructions youre given.

Your doctor or physiotherapist may also suggest that you:

  • Use a knee brace for extra knee support.
  • Try shoe inserts to improve the position of your feet.

  • Activities that stress the knee again and again, especially those with twisting motions.
  • A traumatic injury to the knee, such as a blow that pushes the kneecap toward the outer side of the leg.
  • Problems with the structure of the knee bones or how they are aligned.

You are more likely to have patellar tracking disorder if you have any of the above problems and you are overweight, run, or play sports that require repeated jumping, knee bending, or squatting.

A Meniscus Injury Can Cause Knee Pain Popping And A Locking Sensation

Anther possibility for a pop in the knee and knee pain is a patient that comes in that describes a popping or a locking sensation in the knee. They usually dont have a high impact injury and lets just say theyre walking in the mall, or they do a twisting and turning rotation motion, or theyre playing tennis and all of a sudden their knee catches or gets stuck, and then it becomes very hard to straighten and it becomes painful until they get a pop.

That can mean thats somethings actually getting caught in the joint itself, thats keeping them from extending the knee and that oftentimes means it might be a cartilage or meniscus injury. The meniscus are two discs within the knee. Theres one disc in the inside, the medial ligament meniscus and then theres a lateral meniscus. You can have a tear in either of those discs. They are actually cartilage discs, so this cartilage over time can get soft and all it can take is just a twisting motion, the catch can create a tear so the discs herethis is the medial meniscus, and this is the lateral meniscus. One meniscus on the inside and one on the outside of the knee joint, and you can have a tear right down the middle, like this, and on this view, looking at the knee straight on, like this, it looks like that.
