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:
Causes Of Crackles And Snaps In The Knees
There are various causes of knee snaps and crackles. What matters is whether the sound brings pain, tingling, or swelling. Based on the accompanying phenomenon, you know whether there is a serious problem, lack of movement, or just an excessive load on joints.
If an unpleasant snap in the knees is not accompanied by pain or swelling, then you have nothing to worry about. With age, the cartilage covering the ends of bones wears out gradually causing the bone ends to come in contact with each other. This is a natural process that we cannot change, but can only slow down. We are talking about a situation when you squat or walk, you hear crackling sounds that appear due to the friction of surfaces of a joint. This sound can also be caused by tension in the ligaments and tendons when moving. The cause of snaps during squats and lunges can be muscle imbalance or pressure that it causes on the joints. To get rid of this sound, you need to follow the tips in a combination with the exercises below.
If crackles and snaps are accompanied by pain or swelling, there is an urgent need to consult a doctor. Since these can be symptoms of diseases such as :
Tight Or Maligned Muscles
Tight or misaligned muscles cause an imbalance within the kneecap. This could happen as a result of overexertion. As a result, the imbalance leads to clicking or popping, which has adverse effects.
In the long run, this constant friction leads to worn out cartilage that precedes early onset arthritis.

How To Stop Knees From Cracking: A 10
When you take the stairs, is the creak of the steps followed by the crack of your knees? Do your popping knees get knowing looks from your co-workers when you sit down at your desk? Most of the time, noisy knees are nothing to worry about. Of all the joints that are prone to making a cracking sound, knees are high on the list. Our 2-step 10-minute stretching routine can help silence your clamorous caps. All you need is our Midi Foam Roller and Stretching Strap. You can also use yoga blocks and a towel.
Cracking knees are sometimes called knee crepitus. Crepitus is a sound or sensation that comes from the friction produced between cartilage and bones during movement. Knee cracking happens when you use your knees full range of motion. Activities that involve bending and straightening your knees like standing after sitting, rising from kneeling or squatting can all cause popping, clicking, crunching, or grating. In most cases, knee cracking is similar to cracking your knuckles its a sound and a mild sensation that isnt a problem. If you experience knee pain or swelling around your knees after the popping occurs, you should see a doctor or consult an orthopaedic surgeon for a diagnosis or treatment. There are some schools of thought that believe cracking knees is an indication of arthritis however, there is currently no research to support this claim.
Avoid Long Periods Of Sitting

Anyone that has sat too long in one position knows how this can make your body feel. Common areas that are affected by long periods of sitting include the back, hips, and knees. For your overall health, its always best to take frequent breaks to stand up, stretch, and reset. You can even set a timer if you tend to get lost in your work or other current activity. If you just cant escape your desk or couch at certain times of the day, then consider other ways to keep your knees moving like seated leg exercises or a small pedal exerciser under your desk to at least keep your legs moving.

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.
Do Your Knees Make A Clicking Sound When You Do Squats And Lunges
As part of a regular exercise regimen, you may do squats and lunges. Indeed, squats and lunges are beneficial forms of exercise. In recent times, you may have started to notice one or both of your knees making a clicking sound while you do squats or lunges. Naturally, you may be wondering what causes this sound and whether it is a symptom that requires professional attention.
Oftentimes sounds made by the knees when doing squats and lunges, as well as most sounds from other joints in the human body, are classified as normal. In the end, the mechanics of the knees and other joints simply make some level of noise including clicks, cracks and pops when they are in use. Provided a person does not experience any pain when the clicking sound occurs when doing squats and lunges, the noise medically is classified as benign crepitus, according to the Mayo Clinic.
Even though benign crepitus or a harmless knee clicking sound is not harmful , it can be annoying to a person working out. The most effective way of lessening or eliminating a knee clicking sound is to engage in a thorough stretching routine before working out. In addition, enhancing strength training exercises that focus on the knees and legs represents another strategy to lessen this issue.
Massage therapy can also be useful in lessening or eliminating knee clicking sounds associated with squats and lunges. (In addition, a person garners an array of other benefits from massage therapy, including stress reduction.

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.

Types Of Cracking Sound In Knee
Though most doctors use the term crepitus to refer to joint noises, there are specific terms to refer to the kind of noise and the possible reasons for the noise, too. These terms are based on the duration, frequency and loudness of the sound and can be listed as:
- Cracking or popping: Occurs due to popping of gas bubbles in the joint.
- Pop: A pop is a sudden sharp sound that occurs during an injury. Popping sound from the knee may indicate an anterior cruciate ligament injury or a meniscal tear.
- Clunking: It is a single loud sound that occurs when you flex your knee. The clunking sound occurs when you flex your knee against some form of resistance. In patients with total knee arthroplasty, clunking happens when the patella repositions itself in the socket of the femur .
- A clicking sound is again a single sound that you hear when you flex your knee. Though it occurs due to a meniscus tear.
- Grinding or grating sound: It is used to describe a continuous scratching sound from the knee joint. This kind of sound is very common in those with patellofemoral pain syndrome and osteoarthritis of the knee.
What Is The Reason For Knee Popping
Youve gone too far in a squat or are transitioning from downward dog to triangle pose when you hear cracking in your knees. Knee injuries, along with back injuries, are the most frequent musculoskeletal disability, so hearing a crack or a pop can raise red flags. But what is the source of the noise? There are a number of causes, some of which arent serious and others which are or might become so if not addressed right away.
When you apply force to your joint, nitrogen bubbles in your synovial fluid might burst, causing knee popping. Cavitation is the technical word for this, and its as innocuous as cracking your knuckles. Its usually harmless, but if you dont pay attention, it could turn into a problem. When cartilage on your femur, tibia, or patella wears away, it leaves rough patches that rub against each other, causing knee popping. This isnt necessarily unpleasant, but it can become painful over time and contribute to osteoarthritis. Youll hear cracking and experience pain if your meniscus, a stretchy C-shaped disc that functions as a shock absorber in your knee, is torn. Their knee pop isnt the only thing that makes them stand out.

Do Meniscus Tears Heal On Their Own
In the case of meniscus tears, some people think the injury will heal over time on its own. But the truth is that there are different types of meniscus tears and some tears wont heal without treatment. If your tear is on the outer one-third of the meniscus, it may heal on its own or be repaired surgically.

The Mechanics Of Cracking
Whats creating that cracking or popping noise isnt fully known.
A traditional explanation is that pressure on a joint creates tiny bubbles in the synovial fluid, which pop when they form quickly. Your synovial fluid contains oxygen, nitrogen, and carbon dioxide and cushions your bones from rubbing against each other.
A 2015 study used real-time magnetic resonance imaging of joint cracking that showed the noise was related to cavity formation in the joint fluid, not collapse of a preexisting bubble. The technical term for this is tribonucleation, where two surfaces separate rapidly, leaving a gas cavity.
