What Happens When Your Knee Hurts

Your Knee Keeps Buckling

Knee Pain When Running: Why It Happens

When you got hurt, did it feel like your knee gave way underneath you? Were not talking about a temporary sensation of weakness or some wobbliness, but more like your shin and thigh bone werent connecting or staying in place. A buckling knee could signal an ACL tear or a cruciate ligament injury.

It could start with a small pop or crack, or you could feel it after a strenuous exercise session or a soccer game.

Either way, your knee feels unstable or weak. Your knee may give out momentarily, which is scary because you might not trust yourself to walk safely when this happens. According to Dr. Howard Luks, an orthopedic surgeon, this could indicate a tear in the patella or the quadriceps tendon.

These tendons are on the front of your knees and offer a lot of support to keep you upright. If theyre not in top form, youre bound to feel weak in the knees , and you might not be able to walk at all. If this is the case, you could need surgery.

On the other hand, the weakness could be temporary, caused by wear and tear, improper footwear, or a strain. If youre a weekend warrior or youre over the age of 30 , you might experience this symptom on a regular basis.

However, if the weakness is recurring and happens every time you exercise, its possible you have a time bomb thats waiting to happen. When in doubt, seek advice from a physician.

If your knee buckles under you when you are walking, then it usually indicates instability, she says.

How Is Knee Pain In Teens Diagnosed

Your healthcare provider will ask about your teens knee pain:

  • Is there a known cause for the knee pain does it happen with certain movements or is there no specific known event?
  • How long has the pain been present?
  • Where on or around your knee do you feel pain?
  • Does the pain wake you up at night?

Your provider will perform a physical exam, checking:

  • Kneecap and knee stability.
  • Alignment of lower leg, kneecap and thigh.
  • Range of motion of hips and knees.
  • Thigh muscle strength, flexibility, firmness.

Your provider may order imaging tests including X-rays or a CT scan or MRI .

What Procedures And Tests Diagnose Knee Pain

A health care professional will begin by asking questions related to the person’s general health and then specifically to the nature of the knee pain .

Next, an examination of the knee will be performed. This will include bending the knee through the full range of motion, checking for stability of the ligaments, and evaluating for any tenderness and swelling. It is often helpful to compare the results of the examination of the painful knee with the other knee. Frequently, this is all that is required to make a diagnosis and start treatment. In several research studies, it has been found that an experienced examiner is as reliable as X-ray examination.

Sometimes the doctor might want to do further studies such as the following tests.

Radiologic tests

Plain X-ray can establish fractures and degenerative changes of the knee.

MRI is used to evaluate the soft tissues of the knee for ligament tears or cartilage and muscle injuries.

Blood tests

If gout, arthritis, or other medical conditions are suspected, a health care professional might order blood tests.

Your Knee Is Locked And You Cant Straighten It

If you had a knee injury and you are not able to fully straighten the leg, you might have a locked knee. A locked knee is simply a knee that cannot fully straighten. There are different reasons a locked knee might occur. In some patients, swelling and inflammation can prevent you from fully straightening the knee. In others, a meniscus tear has flipped into the middle of the joint and is causing mechanical locking. You cannot straighten it with the meniscus in that position.

Many athletes who have a locked knee will also find it very painful to bend the knee too. They may feel sharp knee pain when bending which can occur when these bucket handle meniscus tears move.

The most common cause of a locked knee is a unique meniscus tear called a bucket handle tear. A bucket handle tear is considered a serious knee injury and will require surgery to fix or repair the tear. The reason these tears are serious is that a large piece of the meniscus tears flips over and becomes stuck in the middle of the knee joint. You need that meniscus to protect the knee. The vast majority of bucket-handle tears can be repaired. So the sooner we start the treatment process, the better the outcome might be after a meniscus repair.

What Is The Anatomy Of The Knee

What to Expect from your Knee Arthroscopy

The knee is a hinge joint that has a simple purpose. It needs to flex or extend to allow the body to perform many activities, like running, walking, kicking, and sitting. Imagine standing up from a chair if your knees couldn’t bend.

While there are four bones that come together at the knee, only the femur and the tibia form the joint itself. The head of the fibula provides some stability, and the patella helps with joint and muscle function. Movement and weight-bearing occur where the ends of the femur called the femoral condyles match up with the top flat surfaces of the tibia .

There are two major muscle groups that are balanced and allow movement of the knee joint. When the quadriceps muscles on the front of the thigh contract, the knee extends or straightens. The hamstring muscles on the back of the thigh flex or bend the knee when they contract. The muscles cross the knee joint and are attached to the tibia by tendons. The quadriceps tendon is special, in that it contains the patella within its fibers. The patella allows the quadriceps muscle/tendon unit to work more efficiently. The quadriceps tendon is renamed the patellar tendon from the kneecap to its attachment in the tibia.

Bursas surround the knee joint and are fluid-filled sacs that cushion the knee during its range of motion. In the front of the knee, there is a bursa between the skin and the kneecap called the prepatellar bursa and another above the kneecap called the suprapatellar bursa .

How A Knee Works

To understand the potential problems with your knee and why it hurts when you bend it, you need to understand the joint itself. Biologists refer to the knee joint as a hinge joint. This means it can both bend and straighten.

Here are the main parts of your knee and the ways they work together when you bend your knee:

  • Muscles: You have three major muscles that work together for your knee to move. Your quadriceps , hamstring , and calf all work together. When you bend your knee, for example, your hamstrings contract and your quads relax.
  • Bones: Your femur , tibia and patella work together to make your knee bend. The patella sits in a groove in your femur, and the upper and lower leg bones will roll, glide, and spin around the patella. Your muscles control how those bones move.
  • Cartilage: Your knee has cartilage in the knee cap, cushioning the bones so you have shock absorption. The meniscus is that cartilage. It is a spongy substance that moves with the movement of your upper and lower thigh bones.
  • Ligaments and tendons: these are the stringy tissues that connect your bones to bones and bones to muscles . They stabilize your knee so it does not go crooked as you bend. They keep the knee joint in line with your hip and ankle.

Mistakes Runners Make That Can Cause Knee Injuries

For runners, avoiding knee injury is an important consideration while training.

The most common reason for knee injuries in runners is increasing the distance too quickly, warns Brian Schulz, M.D., orthopedic surgeon and sports medicine specialist at Cedars-Sinai Kerlan-Jobe Institute in Los Angeles. Generally, it is recommended to increase distance 10 percent or less per week.

Seven Most Common Knee Injuries

The knee joint is one of the largest and most complex joints in the body.

It is also one of the most important joints. Connecting the thigh bone to the shinbone, it plays an important role in supporting the bodys weight, and facilitating movement allowing you to bend your knee.

Due to the complexity of the knee joint, it is susceptible to a number of different injuries. Some of the most common knee joint injuries include tears in the ligaments, tendons, and cartilage. The kneecap itself can also be fractured or dislocated.

Lets look at some of the most common knee injuries. See how they are caused and the treatment thats required to address them.

Fractures

The kneecap is a shield for your knee joint, and protects it from becoming injured or damaged during a fall. Because of this, the kneecap can become broken during a high impact fall or sports injury.

Kneecap fractures are a common yet serious injury that usually requires immobilization or in some cases surgery to correct.

Dislocations

Knee dislocations occur when the knee bones become out of place. This can occur after a major trauma such as a fall, car crash, or high-speed impact. It can also be caused by twisting the knee while one foot is firmly planted on the ground.

Anterior Cruciate Ligament Injuries

The anterior cruciate ligament is knee tissue that joins the upper and lower leg bones together and helps keep the knee stable.

Posterior Cruciate Ligament Injuries

Collateral Ligament Injuries

Meniscal Tears

What Happens When Your Adductors Are Tight

tight adductorsthetight

Having tight adductors on one side and not the other will make it difficult to hold the pelvis level which means the opposite hip will drop down as you walk. This can then result in hip pain and further imbalance as the body tries to compensate for the tight muscles.

Also Know, can tight adductors cause low back pain? Adductor weakness could be contributing to your discomfortPoor hip stability from weak or tight adductors can lead to low back pain or make it worse. Strengthen these muscles with targeted exercises, however, and you can build a balanced chain of muscles to support your hips and back.

Subsequently, one may also ask, how do you tell if you have tight adductors?

  • Pain in the groin at the top of the adductor muscles that can radiate down the leg.
  • Pain on resisted hip flexion.
  • Pain at a specific point on the bone in the groin.
  • Pain when you press the legs in together against resistance.
  • Can tight adductors cause glute pain?

    The piriformis muscle is one of the small muscles deep in the buttocks that rotates the leg outwards. A common cause of piriformis syndrome is tight adductor muscles on the inside of the thigh. This means the abductors on the outside cannot work properly and so put more strain on the piriformis muscle.

    Problem: Patella Or Kneecap Pain

    When working properly, your patella should glide straight up and down as you extend your leg. But sometimes the kneecap slides slightly off track and rubs against the bone and cartilage nearby. This can lead to pain and swelling in front of the knee and behind the kneecap. You can also hear a crackling noise.

    Your Ankles Could Be To Blame For Painful Squats

    Further down from the hips, we have the ankles. And it is surprisingly the ankles that could be the reason for your knee pain while doing squats. Dr. Aaron Horschig, a physical therapist, tells Men’s Health how having weak ankle stability can be the reason your knees hurt while squatting. To strengthen our ankles Horschig recommends doing multiple repetitions of a box stretch. Start with placing your flat foot on top of a box or platform and press in a downward forward motion until you can feel a real stretching in the back of your calf.

    If it is too late, and you’re already suffering from lasting knee pain after squatting, then it is worth trying the R.I.C.E method to aid in recovery. Healthline tells us R.I.C.E stands for rest, ice, compression, and elevation. It is a great way to remember to take a break and ice your knee for 20 minutes at a time. Both compression and elevation can help minimize swelling and help drain any extra fluid away from the knee.

    If you have previously suffered from a serious injury or just can’t seem to make the pain in your knees after squatting go away, then it’s worth a visit to your medical provider. They can give an accurate diagnosis and help avoid any potential future damage to your knees. Squats may be everywhere, but at least we can do our best to avoid the knee pain.

    What Is Synovial Fluid Analysis Or Knee Aspiration Fluid Analysis

    Synovial Fluid Analysis or Knee Aspiration Fluid Analysis When there is a suspicion of a particular condition, a diagnosis needs to be established. The synovial fluid, which is drained or aspirated from the joint, is examined and analyzed in the laboratory for its nature and presence of certain factors that aid in diagnosis of the condition. Specific findings help in determining the condition causing knee swelling.

    The type of fluid and its detailed analysis guides in making a diagnosis of the condition. Some of the general findings include:

    • Fracture or ligament injuries may show blood in the fluid.
    • Meniscus injury or osteoarthritis may show straw colored or pale yellow fluid.
    • Presence of crystals may mean gout or pseudogout.
    • Turbid fluid or presence of pus may mean there is an infection.
    • Gram staining and culture tests of the fluid can help in detecting the microorganism causing infection.

    Knee Pain With Exercise- What’s Causing It And How To Fix It

    Knee pain usually becomes worse as arthritis progresses. Many people with severe pain from arthritis choose to have surgery to relieve their symptoms and help repair the joint.

    But surgery isnt right for everyone. Some of the more conservative options for treating knee pain from arthritis include medication and at-home strategies like exercise.

    The exact treatment plan thats recommended for your knee pain will depend on factors such as severity of your pain, your age, your activity levels, and any other medical conditions you have.

    Typically, your doctor will try the least invasive type of treatment, such as weight loss and medication, and then move down the line to consider surgery.

    Because there are many considerations before turning to surgery, its crucial to discuss and explore all treatment options with your doctor.
