Why Do Joints Make Noise

WHY YOUR KNEES CRACK | Joint Crepitations

Many people notice that their joints seem to make more noise as they get older. Theres a good reason for that.

The older you get, the more noise your joints can make, because some of your cartilage wears away as part of the normal aging process, Dr. Stearns says. Then these surfaces get a little rougher and so you get more noise as they rub against each other.

And joint sounds can come and go, depending on how you position your body when you sit and sleep, and how you use your body when you move, Dr. Stearns says.

Cracking, popping joints are so common that Dr. Stearns says his patients ask him about them just about every day.

Its a common question, Dr. Stearns says. The bottom line is joints make noise.

About Cracking Sound From Knees:

It is quite common for everyone to hear a cracking sound whenever there is any movement in their knees, especially after getting up from a seated position for a prolonged period of time like in an airplane, going up and down stairs, walking for long distance. All these things cause the knee joint to become stiff and tight. When you hear the knee crack it gives a feeling of relaxation and pleasure and makes the knee a bit more flexible.

There are two questions that come to mind when the knees crack. The first question is why does this happen and the second question is whether it may cause some harm or injury to the knee joint. The answer to the first question has been delineated in detail below and the answer to the second question is that when there is Knee Cracking it is not the bones that are actually cracking as then it would lead to intense pain and you will not be able to move your knee. Thus, generally Knee Cracking do not cause any injury nor does it predispose you to any medical conditions, except when you already have a known diagnosis of a degenerating knee joint.

What Is The Clicking

The clicking could occur for a few different reasons. Although the noise can be quite alarming on occasion, they are seldom a reason to worry.

Believe it or not scientists first studied the clicking or popping noise in 1947! There was much debate initially but in 2015 a real-time medical imaging study of joint spaces revealed the answer!!

The noise occurs because tiny air bubbles accumulate within the fluid inside your joints and when you move, they collapse due to the changes in pressure inside the joint. The noise occurs when the gas bubbles collapse. When the bubbles burst this is called cavitation. It is the same process as when you click your knuckles !

In the knee this can occur from either the knee joint itself between the tibia and the femur , known at the tibio-femoral joint or the joint on the front of the knee between the patella and the femur , known as the patellofemoral joint.

This mechanism is why you hear the clicking noise if your physiotherapist or osteopath applies a short, sharp movement to one of your spinal joints. It also explained why you cannot keep clicking the same joint in quick succession. It takes approximately 20 minutes for the gas bubbles to reform.

Here are the other reasons for clicking at the knee that we see in clinic:

Both these conditions are often pain free and are often nothing to worry about.

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.

What Are Some Of The Causes Of Knee Cracking

Why Does My Knee Pop?

Now we go into the details of what actually produces the cracking sound with any movement of the knee. For this, we need to first understand about a fluid which is present in the body called the synovial fluid. This fluid is present between the joints in the body and acts as a lubricant or shock absorber. This synovial fluid is present in the synovial membrane which encompasses the end of our bones.

The synovial fluid prevents the bone from rubbing against each other such that there is increased friction between bones which may lead to degeneration of the bones, a condition called as arthritis.

Coming to the cracking sound, when we move a tight or stiff knee, the space between the bones gets expanded which results in a gap being created between the bones where synovial fluid rushes in to fill the gap.1 The movement of the synovial fluid in this gap is what that produces cracking Sound.

There are certain other causes for Knee Cracking as well and these are:

Osteoarthritis Of The Knee

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.

Other Tips For Dealing With Cracking Knees

Heres some advice to maximize your knee health and stability:

  • Practice non-impact knee strengthening exercises like cycling, spinning, water aerobics or swimming
  • If you have pain after workouts, apply cold for 15 to 20 minutes to each knee. Try a bag of ice wrapped in a damp towel
  • Dont squat for long periods or sit in uncomfortable positions get up and move around frequently, for example, during long plane rides.
  • Make sure you use well-fitting footwear avoid walking in bare feet or on uneven surfaces
  • Consult with a physical therapist about knee strengthening exercises you can do at home
  • Keep your weight under control to put less strain on your knees avoid carrying heavy loads, especially up and down stairs

Crepitus Following Surgery Or Trauma

Why Does My Knee Snap, Crack, or Pop? Is it Harmful? What To Do?

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:

Is Age A Factor In Joint Cracking

Age can contribute to joint cracking. As you age, your joints make more noise as the cartilage wears down. You do not need arthritis to have joint cracking with age.

You may only notice the noise when you do certain movements or in certain joints. Through strengthening muscles around those joints, symptoms can often be relieved.

Cartilage Injury Or Wear

In an injury, knee cartilage can break off and catch on the joint, which causes pain and swelling.

Or, the cartilage may wear down from arthritis, which leads to a painful grinding feeling during movement.

If youre concerned that either of these causes could have led to painful or swollen cracking knees, find a clinic near you and book a physiotherapy assessment today.

What Is Knee Crack When Squatting

When you’re in a squat position, you put pressure on your knee joints, whether you’re exercising or doing daily activities. The joint reaction to this pressure may be different sometimes you hear it as a pop sound, or sometimes you may experience extreme pain in your knees.

Some Concern: Persistent Popping With Swelling Pain Catching Or Grinding

When the knee popping sounds are accompanied by swelling and pain, or produce a catching sensation, or the knee gives way, I worry about a possible injury within the knee. A physician should examine the knee to help make a clear diagnosis.

In this case, there are several possible explanations for the popping. The noise and pain may be a mechanical symptom, which feels like something is caught in the knee as it moves back and forth. This kind of popping is often a sign that you have a meniscus tear, or that a small piece of loose cartilage is caught in the knee. You would most likely feel this kind of popping pain come and go. An exam, X-ray, and MRI will tell the definitive story.

Painful knee popping can also be caused by osteoarthritis, where the smooth cartilage has worn down and the bones cause friction when they rub against one another. This painful popping would be more persistent.

Another common problem that results in a popping or grinding sensation is roughness on the undersurface of the patella. This used to be called chondromalacia, and is often labeled as patellofemoral pain syndrome, or runners knee. Often you may feel the popping, grinding, or crunching more than you can hear it. To feel this, try squatting with your hand flat over the front of your knee.

For each of these types of knee sounds, if there is no tissue torn, anabolic injections of growth factors plus lubricants has been surprisingly and often dramatically effective.

Tips For Healthy Knees

  • Regular exercise can strengthen your legs and knees. Exercise with weights or resistance bands — or do bodyweight moves, like squats and lunges — at least twice a week. Walk up stairs or hills, or ride a stationary bicycle to build muscle to support your knees.
  • Warm up before you exercise. An intense workout with cold muscles and joints can cause injury.
  • Keep flexible. Before exercise, try dynamic stretches, in which you move a muscle through a full range of motion. After exercise, do static stretches, where you hold a stretch for 30 seconds. This helps prevent injury. Regularly stretch the muscles in the front and back of your thigh .
  • If youâre already exercising, slowly work up to harder, longer workouts.
  • Wear shoes that fit right and are in good condition.

âThe best thing is to keep the muscles around the knees strong,â McAllister says.

How To Keep Your Knees Strong And Healthy

Regular exercise

Whether with weights or resistance bands can help strengthen your legs and knees protecting them from injury. To protect the cartilage in your joints its best to choose low impact activities like cycling, swimming, and body weight activities.

Keep your joints flexible

After you exercise, stretch your muscles. This is a great way to prevent injury and allow your joints to move more freely.

Wear shoes that fit right. Old shoes can put more stress on your knees and cause injury.

Maintain a healthy weight. Being overweight puts extra stress on your knees contributing to arthritis.

Physiotherapy can help build up your knees and slow down the aging of your joints.

It does this by strengthening your upper and lower leg muscles. If you have muscle imbalances in your hamstrings, glutes , hip flexors, psoas, and quadriceps it can contribute to knee injuries or problems.

Knee Brace can provide extra support when you move around.

Why Do My Joints Crack During Exercise

Why does my knee pop and crack?

Athletes can hear joint cracking when they participate in strenuous activities such as running and plyometricsthe sound results from tight muscles that are causing friction against bones. If athletes stretch appropriately before exercise, it can help to relax the muscles. In doing so, you can decrease the number cracking sounds, as well as decrease the risk of injury.

Are Cracking Knees A Sign Of Osteoarthritis

Not on its own.

It can be a sign of knee osteoarthritis if its associated with at least 2 of the following:

  • Knee pain in most days for the last month, that gets better with rest.
  • Loss of range of motion.
  • Morning stiffness on the knee.
  • +50 years old.

If so, go to a doctor and physical therapist to plan your treatment.

No Worries: Painless Clicks & Pops

Sometimes the noise is due to tiny air bubbles inside the joint fluid, which build up with changes in joint pressure. The bubbles make a noise when they burst. This is called cavitation. Another cause for painless popping in the knee is when the ligaments and tendons catch as they go over a bony lump within the knee or over scar tissueand pop when they snap back into place. 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. Soft tissue massage is the trick to resolving the naturally healing tissues excess thickness.

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.
