Why Do I Have Knee Pain at Night?  Health Essentials from ...

What Is a Posterior Cruciate Ligament Injury?

The posterior cruciate ligament is the strongest ligament in the knee joint. Ligaments are thick, strong bands of tissue that connect bone to bone. The PCL runs along the back of the knee joint from the bottom of the thighbone to the top of the lower leg bone .

The PCL helps keep the knee joint stable, especially the back of the joint. An injury to the PCL could involve straining, spraining, or tearing any part of that ligament. The PCL is the least commonly injured ligament in the knee.

A PCL injury is sometimes referred to as an overextended knee.

The Pros And Cons Of Cortisone Shots

If you’re experiencing pain that makes it difficult for you to start physical therapy to address your knee problem, your doctor might recommend that you get an injection of cortisone to lessen the pain.

The shot injects a corticosteroid drug and a local anesthetic into the joint to temporarily relieve pain and swelling. But it isn’t a long-term fix. “Often people think that injections, especially cortisone injections, will fix a knee problem. What they do is provide a window of pain relief so you can make progress with rehabilitation,” says Dr. Rebecca Breslow, an instructor in orthopedic surgery at Harvard Medical School. “But when cortisone injections are overused, there is some evidence that they can actually accelerate osteoarthritis.”

In short, while cortisone shots put you on the path to healing, they should be used judiciously and aren’t a permanent solution to the underlying problem that’s causing your knee pain.

Where Is Your Pain

The hunt for the cause of knee pain is like the search for a home:Location matters.

For example, pain below your kneecap might be a sign of patellar tendinitis, or inflammation in the tendon that connects the kneecap to the shinbone, says rheumatologist Scott Burg, DO. Pain above the kneecap often means quadriceps tendinitis.

Pain on the inside or outside of your knee could be a sign of a torn ligament , Dr. Burg says. But it also could indicate a torn or degenerative meniscus, which is the cartilage that lines and cushions your knee joint.

Those are just a couple of causes, not including various types of arthritis. Location is important, but we also ask other questions, Dr. Burg explains.

What Causes Sharp Stabbing Pain In The Knee That Comes And Goes

How to get rid of your knee pain instantly

There are all kinds of causes for this specific type of pain in your knee. As we covered right off the bat, the knee is a very complex joint that has many, many different components.

So, think about which side of the knee you feel pain in. If you feel it on the back of your knee, for example, it could be an issue with your ACL.

If your pain seems to be just radiating from the knee in general and you cant necessarily pinpoint the exact location, it may be something more general, like arthritis.

Obviously, a trip to the doctor to get tests performed, along with an x-ray, are your best bet. This way, you can come up with a tailored treatment plan, rule out surgery, and get back to feeling better and doing the things you love. But in the meantime, here are some things you may want to look into.

Severely Affected Blood Flow May Require Surgery

If a person has severely affected blood flow in the legs or medications dont help, a doctor may recommend surgery to restore blood flow.

Examples include angioplasty, which involves inserting a small balloon to open up the artery, or vein bypass surgery. Indications for surgery usually depend on the underlying cause.

Treating Leg Pain At Home

The following are some ways that may help you treat intermittent leg pain at home:

  • Exercise regularly. Although exercise can contribute to some leg pain, exercise sessions at least twice a week helped to reduce walking pain and increase the distance a person can walk, according to a 2017 review.
  • Stop smoking. If you smoke, quitting is recommended. Smoking is a major risk factor for sharp pains when walking. Smoking can cause changes to blood vessels and make it easier for the blood to clot, which can contribute to leg pain.
  • Eat a heart-healthy diet. Choosing a heart-healthy diet can help you maintain your weight and blood sugar levels. This can help reduce some of the risk factors that can lead to PAD.
  • Cross-training. If your leg pain is related to overuse from physical activity, try a new activity thats less repetitive on the legs and feet, such as taking an aerobics class or swimming.

Maintaining a healthy weight and taking care of your body can help reduce the sharp, shooting pains whenever possible.

Seek immediate medical attention if you experience the following symptoms related to your leg pain:

  • lack of pulses in the ankle or top of the foot
  • leg that feels very cold to the touch
  • leg that starts to appear blue or discolored
  • severe leg pain that doesnt get better with rest

You should talk to a doctor if you have chronic leg pain, even if it goes away when you rest.

Symptoms Of Pain Behind The Knee

Since several conditions can cause pain behind the knee, the symptoms can vary. The most common symptoms include:

Varying types of pain

The pain can be sharp, dull, or burning. It may come on suddenly or gradually. It may be constant, or it may occur when you put weight on the leg or when you bend the knee. This information can help a doctor diagnose your knee problem.

Swelling or stiffness

The knee may look swollen or misshapen. You may be unable to bend the knee, or your knee may pop, lock up, or collapse when you put weight on it. These symptoms usually indicate that you have sustained an injury, but there are other possibilities as well.

Redness or warmth

Under certain circumstances, the back of your knee could feel hot to the touch, or redness could be visible. You might also have a fever. These symptoms would point to a different cause than if you only have pain.

Burning Pain In Knee When Kneeling

I have knee pain on the inside of my knee, NISHIOHMIYA ...

Many people immediately believe they have knee arthritis when they feel pain as they kneel. However, sharp burning pain in knee areas when kneeling does not mean you have to acquiesce to a lifetime of painful arthritis.

Sharp, burning pain in your knee might just mean you have sore muscles.

Picture the anatomy of your knee. The thigh muscles and lower-leg muscles are both attached to your patella or knee cap with tendons.

When you strain your muscles, they fill up with lactic acid, giving them that painful tight sensation after you exercise. Tight muscles d not flex. So as you attempt to flex your knee and muscles do not respond with proper stretching, you may feel a burning sensation in your knees.

Ligament Sprain Or Tear

Knee ligaments

Ligaments are soft tissue structures that help to stabilize the joint. A complete tear of any of the ligaments can cause stability issues along with pain and significant swelling. Partial tears of the ligament can cause sharp pain with movement along with some swelling.

Listed above are only some of the problems that may arise at the knee joint. It is important to be evaluated properly if you are having sharp knee pain. Many of these conditions can be managed conservatively and respond well to physical therapy. Stretching, strengthening and manual therapy can aid in recovery.

JOI is an expert with sharp knee pain. If you suspect that you may have one of these injuries, you should consider seeing a specialist. Be smart about your health. Get assessed, dont guess!

Investigation Of Pain Inside The Knee

Your doctor will ask you about the type of pain you are feeling, and also note the size of your affected knee compared to your unaffected knee. Any discolouration and warmth will be noted as will the range of movement you are able to effect. The doctor may need further investigation in the form of medical imaging to detect fluid or a possible fracture, and perhaps a blood test to identify any rheumatoid factor or antinuclear antibodies. Fluid may also be drawn from the knee to test for uric acid or bacteria if an infection or inflammation is suspected.

Sharp Knee Pain Causes By Activity

  • Sharp Knee Pain When Walking: If the knee pain is worse when you first start walking and then eases, it is likely due to arthritis. If your sharp knee pain gets worse the more you walk, it is likely neural. If it is easier walking uphill or when bent slightly forwards and worse when walking downhill or when upright, it is likely spinal stenosis
  • Sharp Knee Pain When Bending: If your knee pain gets worse when bending your knee, it is likely a problem in the knee joint such as arthritis or a cartilage tear. If it is worse when bending your back e.g. reaching down to put your shoes on, it is likely due to a problem in your lower back
  • Sharp Knee Pain When Standing: If the knee pain gets worse when standing still but eases with movement, it is likely from arthritis. If your sharp knee pain gets worse with activity it is likely a mechanical problem in the knee such as a cartilage tear or referred pain from the lower back
  • Sharp Knee Pain Twisting: This usually indicates that something is getting stuck in the joint, either a loose body or a flap of torn cartilage. It may also indicate instability in the knee due to a ligament sprain or tear
  • Sharp Knee Pain When Kicking: This usually indicates an issue with the stability of the knee, typically an ACL injury
  • Severe Sharp Knee Pain: with unrelenting pain usually indicates a fracture of one of the knee bones or something more sinister going on – worth seeing your doctor

    Sharp Knee Pain When Standing Or Walking Upright

    If, when you stand up tall, that sharp, shooting knee pain occurs, it is likely spinal stenosis.

    Spinal stenosis is the narrowing of the space between each vertebra and occurs most often in the lower back and the neck. Commonly caused by osteoarthritis, stenosis can put pressure on the nerves that travel through the spine, just like mentioned above.

    TIPS TO AVOID PAIN: exercises like strengthening the muscles surrounding the spine and focusing on flexion-based mobility will decrease the amount of pressure on the nerves that travel down to the leg. Try these lumbar flexion exercises to create some space between your spine and your nerves.

    Causes Of Pain Behind The Knee

    Pain behind the knee can be simple or difficult to diagnose, depending upon the cause. Here are some of the most common causes of posterior knee pain:

    Baker’s cyst

    A lump-like swelling behind the knee is characteristic of Baker’s cyst, making it fairly easy to diagnose. This type of cyst is also called a popliteal cyst because it is located in the popliteal fossa, a small hollow at the back of the knee.

    It forms when synovial fluid gathers at the back of the knee. Injury or stress from arthritis can trigger the accumulation of fluid.

    Different forms of arthritis

    Arthritis is the generic name given to diseases that affect the joint. Arthritis can cause pain anywhere in the knee joint, including the back.

    Knee pain is most often associated with osteoarthritis, the type that is related to aging or overuse. Knee pain can also occur with rheumatoid arthritis, but it will occur in both knees at once.

    Gout is a type of arthritis that first attacks the big toe, but later attacks may strike the knees. Septic or infectious arthritis is caused by an infection that lodges in a joint, usually a knee.


    Besides infection in the knee joint , posterior knee pain could result from several other infections, including:

    • Infection in the bone
    • Infection of one of the fluid-filled sacs called bursae

    These infections have different causes and symptoms, although pain, redness, heat, and swelling are typical of most infections.

    Sharp Knee Pain When Squatting

    Biking to Manage Arthritis

    If your knee pain gets worse when bending during squatting, it is likely a problem within the knee joint itself, such as arthritis or a cartilage tear.

    It also needs to be noted that weakness in the hips or ankles can also cause your sharp knee pain from arthritis to get worse. Thats why its important to look at the whole lower body and how it is functioning when you are bending your knee.

    TIPS TO AVOID PAIN: when we squat well, we live well! Fix these common mistakes made during squatting to address the hip, ankles, and knees to reduce sharp knee pain.
