Why Does My Knee Pop

Why Does My Knee Pop With Every Step

This type of popping symptom is often a sign of a meniscus tear or a loose piece of cartilage within the joint. 1 These are tissues inside the knee that help cushion and protect the joint. The torn meniscus or loose cartilage may catch in the knee as it moves back and forth. This causes a popping sensation.

Anatomy Of The Menisci

These c-shaped, strong, yet somewhat flexible structures of the knee are made of collagen and act as shock absorbers. They also help to stabilize the knee joint. They are located on the tibial plateau. There are two menisci: named medial and lateral based on where they are located.

• Medial menisci: More stable and fixed and therefore is more likely to become injured.
• Lateral menisci: More mobile and is therefore somewhat less likely to become injured.

Knee Popping By Activity

Knee Popping When Extending: Knee popping when you straighten your knee is usually due to gas bubbles , plica syndrome or patellofemoral pain syndrome.

Knee Popping and Pain When Bending: If you get knee popping and pain when bending your knee e.g. squatting down, it is most likely due to a problem with the knee cartilage such as a meniscus tear or chondromalacia patella.

Knee Popping When Extending And Bending: If you get knee pain and popping with both knee flexion and extension, it is likely that there is damage to the joint surface such as cartilage damage or knee arthritis. If there is no pain, it is likely to be gas bubbles popping.

Knee Popping With Twisting: Sudden knee pain and popping when you twist is usually doe to a knee ligament injury, most often an ACL injury and/or MCL tear. If the knee swells up or feels unstable after hearing a pop as you twisted, seek medical attention immediately.

Knee Popping When Walking: Almost all the possible causes of knee popping that we’ve looked at here can cause knee pain and popping when walking, be it arthritis, runners knee, cartilage tear or ligament injury. There will usually be other symptoms associated here that will lead to a clearer knee pain diagnosis.

Why Does My Knee Click

Posted on:

If you have ever heard your knees making noise when you step up, bend down, or stand up, it can be a little unnerving. What is causing it? Is there a problem with your knees?

Many of our joints can make noises at times and knees are no different. So why do knees click or pop when they bend? And when is it a concern?

There are several possibilities for the clicking or popping noises you may hear:

Air bubbles in the synovial fluid: Synovial fluid is found in all our joints. It helps the bones glide smoothly over one another. Air bubbles can form in this fluid. When you bend your knee, these tiny bubbles can escape and result in a popping noise. These escaping bubbles do not cause any pain and are not an indication of any problem.

Movement of ligaments or tendons: The ligaments and tendons around your knee connect bones and muscles together and give us the ability to move and bend. An unusual rotation or movement of your knee may cause a tight ligament or tendon to pop. Along with a popping sound, tight tendons or ligaments can cause some pain in the knee. Stretches or release exercises can help relieve the tension and treat the pain.

Damage To The Knee Joint

Sometimes, however, there is an underlying problem, for example, tissue damage or lesions. In this case, treatment may be necessary.

If there is pain as the knee snaps or catches, it can be because scar tissue, a meniscus tear, or a tendon is moving over a protruding bone within the knee joint.

Pain or swelling can be a sign of a more serious problem, such as patellofemoral pain syndrome , a tear in the cartilage or other soft tissue, or osteoarthritis .

These issues may need medical attention. Lets look at them now in more detail.

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.

• Stay at a healthy weight. Youâll reduce stress on your knees. Being overweight is a major risk factor in developing early arthritis of the knee.

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

Treatments For Knee Popping And Snapping

Knees that experience painless popping and snapping are usually normal and do not need any treatment, says Dr. Gibson. Painful knee popping may respond to rest, ice, elevation, and avoidance of the activity causing the pain.

Depending on your specific condition, your healthcare provider may recommend one or more of the following treatments.

Reasons Not To Worry About Your Clicking Knees:

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.

If you are worried about your clicking knees and would like to book an appointment or for more information please email or call 0207 482 3875.

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.

Is There Any Treatment For It

Some will perceive fewer knee noises after losing some weight, or after starting an exercise regime.

In healthcare, we usually treat the noises when theres joint pain or an injury involved.

For example, if the noise is due to a ligament tear, we treat the tear. Once its managed, the crack or pop should disappear.

Why Does My Knee Pop But Not Hurt

What Are The Possible Causes Of Clicking And Catching Of The Knee

Cavitation. Sometimes the noise you hear is due to tiny air bubbles inside the joint fluid, which build up with changes in the joint pressure. When the bubbles burst, this is called cavitation. Cavitation is typically something that is not worrisome as long as it is unaccompanied by other symptoms .

Ligaments and tendons. Another possible cause of clicking and catching of the knee is when the ligaments and tendons catch as they go over a bony lump and pop as they snap back into place. Like cavitation, this is also not considered to be a serious problem if unaccompanied by other symptoms.

Soft tissue. Clicking may also be caused by the catching on soft tissue or scar tissue within the knee. Most of the time, these noises are natural and do not necessarily mean that youll develop other issues .

Meniscus tear. If you feel some pain as the clicking/popping occurs, it could be a sign of a meniscus tear, which means there is a small piece of loose cartilage caught in the knee. Treatment for a torn meniscus commonly includes rest, pain relievers and physical therapy. Less commonly, surgery may be required.

Osteoarthritis. If youre experiencing painful and persistent clicking/popping, it could indicate osteoarthritis, in which the smooth cartilage has worn down and the bones cause friction when they rub against one another.

When Should I Be Concerned Enough To See A Physician

If you experience the clicking and catching and its accompanied by swelling and/or severe and persistent pain its time to see your physician for an examination and clear diagnosis. Also, if theres a pop at the time of an injury and your knee begins to swell, it could very well be a sign that there has been damage. It could mean that you injured your anterior cruciate ligament, posterior cruciate ligament or medial collateral ligament or the meniscus or articular cartilage.

A good rule of thumb is that if you experience clicking and catching of the knee, but feel no pain or swelling whatsoever, its likely normal. However, if you have pain, instability and/or swelling, be sure to see your physician in order to avoid further damage to the joint. Of course, if youre worried even without pain or swelling, you should still consider seeing a knee specialist for your own peace-of-mind.

Less Common Causes Of Knee Pain

Less-common causes of significant knee pain include conditions and injuries. Injuries include:

• Dislocated kneecap: Causes are sharp blows to the knee or twisting. Severe pain in the front of the knee plus buckling, slipping, or catching during movement.
• Kneecap fracture: Causes are a direct blow or falling onto the knee. Pain, difficulty straightening the leg, bruising, and swelling can occur. Sometimes there’s visible deformity.

Conditions include:

• Gout: High uric acid levels form sharp crystals inside the joint. Affects the knee, hip, fingers, and especially the big toe. Pain can be severe.
• Plica syndrome: Irritation of the synovium . Pain is in the middle and front of the knee. Worsens with inactivity or squatting, running, or kneeling. The knee may pop when bent.
• Osgood-Schlatter disease: Strikes after growth spurts in kids between 9 and 14. Pain is in the front of the knee. It improves with rest and worsens with activities like running and jumping.
• Osteochondritis dissecans: In children, lack of blood supply weakens the bone and cartilage. The knee may separate from the underlying bone. Causes pain with activity.
• Knee joint infection: Causes significant pain, swelling, warmth, painful movements, and fever. It may result from a bacterial infection in the bloodstream.
• Bone tumor: Very rarely the source of knee pain. Symptoms include fever, unintentional weight loss, and pain that’s worse at night.

How Long Can You Walk On A Torn Meniscus

As this healing occurs, patients progress towards bearing weight, increasing their range of motion, and leaving the knee brace behind. How quickly this progress occurs varies by surgeon, but a typical range is 4-8 weeks. Patients are usually out of the brace and walking without crutches around 2-3 months.

Exercise : Calf Stretch

• Place your hands slightly wider than shoulder-width apart on a wall.
• Step back with the foot of the affected leg, far enough so that you feel a stretch in your calf. Make sure your toes are pointed toward the wall, and your foot is perfectly straight.

Avoid this common mistake: If you turn or angle your foot even slightly, you wont stretch the muscles and fascia youre supposed to.

• Straighten the affected leg .
• Bend the leg closest to the wall until you intensify the calf stretch to between 8 and 9 on your personal pain scale.
• Hold for between 2 and 2.5 minutes.
• Repeat on the other side.
