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.

Treatment for a torn meniscus commonly includes rest, pain relievers and physical therapy. Less commonly, surgery may be required. Osteoarthritis.

  • Stand in a split stance, keeping all of your weight in your front leg.
  • Squat straight down, stopping halfway. Your front knee should stay directly over your ankle.
  • While squatting, twist your front leg to the right, hold for 3 to 5 seconds.

  • Do three sets of 15 on each leg.

    Exercises To Stop Knee Clicking

    Prior to beginning any exercises for knee clicking, you should always consult with your doctor, as some exercises can make your condition worse, for example, if you have a tear or misalignment. If your doctor has given you the green light to exercise, then a good place to begin is strengthening the quadriceps, as the muscles that run through the thigh can help better support the knee.

    Beneficial exercises for quads include leg extensions or static contractions. An example is quad-setting exercise, which is performed by sitting on the floor with both legs straight. Bend your left knee and put your foot flat on the floor and place a rolled towel beneath your right thigh near the knee. Flex your foot, and lift your heel and calf off the floor. Lower back down. Do not lift your thigh off the towel.

    Its also important to have equal strength between your quadriceps and hamstrings, so if your quads are strong but your hamstrings are weak your knees could be feeling the burden. Hamstrings are located at the back of the thigh. To strengthen these muscles, lay face up on the floor with your knees bent at a 45-degree angle. Lift your toes up and press your heels down, contracting the hamstrings in the process. Hold this for up to 10 seconds, relax, and repeat. Generally, the quads should be only 25 percent stronger than the hamstrings.

    Crepitus And The Crackling Sounds In Your Joints

    Why Do the Knees Click When You Bend or Straighten Them?

    Crepitus is the abnormal popping or crackling sound in either a joint or the lungs, which may be faint or loud enough for people to hear. It is often accompanied by a popping or crunching sensation that may sometimes be uncomfortable or painful.

    Crepitus in the joints is typically related to joint damage. Crepitus in the lungs is caused when collapsed or fluid-filled air sacs abruptly open upon inspiration.

    Causes Of Knee Clicking

    Patients often ask, Why is my knee clicking? Associated symptoms can indicate whether your knee clicking is serious. For example, knee clicking when straightening the leg is particularly common and is often totally normal. Knee clicking and pain, however, may be a sign that something is wrong.

    What Causes A Clicking Sound In The Knee

    The knee joints can be noisy. Knee clicking, popping, or crunching sounds are common and typically no cause for concern. Theyre often the result of soft tissue stretching over the joint or bony protrusions.

    But if you experience knee clicking with pain or swelling, it may indicate a serious injury or osteoarthritis.

    Your knee joint sits where the femur , tibia , and a protective shield called the patella meet. Since the knee bears most of your body weight, its cartilage, ligaments, and tendons are especially vulnerable to everyday wear and tear.

    Two pieces of cartilage act as shock absorbers, providing a cushion between the femur and tibia bones. These are the menisci.

    Other essential parts of the knee include the articular cartilage, the collateral and cruciate ligaments, and the quadriceps and patellar tendons.

  • For conditions that cause swelling and inflammation, our K-Laser therapy can be the best approach. The K-Laser passes through the skin into the tissues of your knee, generating energy into the cells. This can increase blood flow to the area which helps to pump nutrients into the knee. This quickens the natural healing process of damaged tissues.
  • For many forms of knee pain and stiffness, shockwave therapy is especially effective as it helps break down scar tissue around the joint and improves movement. Shockwave can be a fantastic therapy for a condition like tendonitis. Tendon injuries can be much slower to heal due to the lack of blood flow in the area. Shockwave is able to increase the blood flow to the area this helps the condition heal much better.

    Real Worry: Loud Pop At Time Of Injury Followed By Swelling Instability And Giving Way

    When a patient says to me, Doc, I heard a pop and my knee swelled, it is definitely a cause for concern. If there is a pop at the time of injury, the knee has almost certainly been damaged. You have most likely injured either your ligaments anterior cruciate ligament, posterior cruciate ligamentor medial collateral ligament or the meniscusor articular cartilage. The knee will usually swell up after these kinds of injuries.

    If there is pain, swelling, or giving way of the knee, we will do a careful exam, history, X-ray, and MRI. By studying the cartilage and soft tissue within the knee, we can determine which tissues need to be repaired. Sometimes careful physical therapy, combined with injections, can fix the problem and help you avoid surgery.

    So remember: If you hear clicks and pops in your knee but feel no pain or swelling, dont worry. It is normal. If you have pain, instability, or swelling, make sure you check it out to avoid further damage to the joint. The philosophy on this has changed from rest your knee and wait until you are older for a joint replacement to fix the problem ASAP by repairing, regenerating, or replacing the missing tissue and cartilage so that you may never develop arthritis or need a knee replacement.

    While it is always best to hear the sounds of silence, snap, crackle, and pop sometimes need to be listened to as well.

    Why Do My Knees Crack

    Why does my knee replacement keep clicking?

    There are a few reasons why knees snap, crackle, and pop. It could be that your knees are cracking because of:

    • Cavitation. This is a process that occurs when the joint pressure in your knee changes. Your joints are surrounded by a liquid called synovial fluid. Carbon dioxide usually dissolves in synovial fluid. When there is a change in the pressure of your joints, carbon dioxide flows out of the synovial fluid, becoming bubbles in the joint. These bubbles form a chamber of air, or a cavity, that makes a popping or cracking sound when it bursts.
    • Tight thigh muscles. If your thigh muscles are too tight, your knees range of motion is limited, and they will make a popping sound when you move.
    • A ligament or tendon that has gotten caught on a bony bump during movement and is snapping back into place.
    • A kneecap that is larger than the indention in your thigh bone where it rests.
    • Cartilage deterioration. As we age, our cartilage wears down and it can become uneven. If the cartilage covering the underside of your knee cap is rough, it can make a clicking sound as it glides across your thigh bone .

    Diet: High Potassium And Sugar:

    A recent study shows that too much potassium and sugar in the diet may be detrimental to the knee joint. The study found that too much potassium caused cells in the synovial fluid to die, leading to a decrease in lubrication of the joint. This could lead to degeneration, inflammation, and arthritis. Too much sugar can cause inflammation by increasing blood glucose levels, which triggers an inflammatory response in the immune system.

    Should You Worry About Knee Clicking

    If the clicking is causing you pain or making it difficult to move then it is important to seek medical attention to determine whether or not you’re suffering an injury that could be causing damage to your body. Your doctor will examine your knee to determine what is causing the clicking noise to help narrow down what kind of treatment is appropriate.

    When the clicking knee is not accompanied by other side effects such as pain or swelling then it may not be cause for concern. Many times the knee will click when it is expelling excess air that has become trapped in the joint. It may also be a sign that the knee is righting itself when it is experiencing excess pressure or friction in the area. This is similar to the sensation or noise that you experience when you “crack” your knuckles or other joints.

    How To Treat Clicking Knees

    Home Remedies

    Knee clicking can often be treated at home. If excessive exercise is causing the clicking, providing additional support during your exercise routine can help alleviate your discomfort. Wearing a supportive band around the knee can help alleviate this condition. Just be sure to pick a proper sized band for your body size so that it does not cut off the circulation to the rest of the leg.

    Doing Exercises

    Sometimes exercise to strengthen the knee can help alleviate the clicking you are experiencing. Working the quadriceps is a common choice for this.

    Common exercise for this is a quad setting.

    • Sit on the floor with both legs straight in front of you.
    • Slowly bend the knee and but the foot on the floor with a rolled up towel sitting underneath the opposing thigh.
    • Flex the foot on your bend leg and lift the calf off the floor, hold for ten seconds and then slowly lower it back down, taking care not to lift the opposing leg off of the towel.
    • Repeat several sets of these with each leg as necessary.

    You can also exercise the hamstrings to help provide the knee with more support while you perform other activities.
