Causes For Pain Behind The Knee And Items That Help

It might come as a surprise but the knee joint is actually really complex, being made up of tendons, muscles, multiple bones and other tissues so it makes sense that any pain you may feel in that area is not only really common but could have many different causes as well!

There are many people who experience pain right behind the knee but unfortunately get incorrect diagnoses precisely because of the different parts and related problems that can be the cause of such pain.

After all, if you’ve experienced it and looked it up online, you know all too well the multitude of scary results about what might cause it including posterior cruciate ligament tear and deep vein thrombosis.

Naturally, those results could be accurate and a cause for concern but, realistically, they are not as common when it comes to pain behind the knee.

While there are a variety of different causes, sometimes, posterior knee pain is also referred from the spine or the front of the knee.

And since there is a number of different conditions that can cause it, the symptoms can also vary a lot. Here are the most common:

– First of all, the pain type may vary from dull pain, to sharp pain or even burning. Furthermore, it can come gradually or suddenly. It is also possible for the ache to happen when you bend your knee or simply when you put weight onto the leg. Such details can really help a medical expert correctly diagnose you.

– Stiffness or swelling are also quite common, making the whole knee look misshapen or swollen or making it hard for the patient to bend the knee. It also sometimes pops, locks up, or collapses upon putting weight on it. While this type of symptoms usually occur as a result of an injury, there are other possible causes as well.

– The back of your knee can feel hot to the touch or you might even see some redness around that area or experience a fever! It is important to note that if you have such symptoms, the diagnostic might be quite different than if you only experience pain.

Causes for Pain behind the Knee:

With so many different possible symptoms to experience, it makes sense that there are many possible causes for it. Some of the most common are:

Arthritis As you may be aware, Arthritis is an umbrella term used to refer to a number of different diseases that affect the joints, including the knees.

With that being said, it is important to note that such diseases are capable of causing pain anywhere around the knee area, including the back of it.

Most often than not, knee pain is linked to osteoarthritis, an illness related to aging.

Rheumatoid Arthritis also causes knee pain, the important distinction being that it occurs in both knees at the same time.

Another related disease is Gout, an arthritis type that attacks the big toe at first, later possibly affecting one’s knees as well.

Finally, septic or infectious Arthritis is usually caused by an infection of a joint, most commonly the knee!

Baker’s cyst

If in addition to pain you also have a lump or a swelling behind the knee, you might have what is known as Baker’s cyst, one of the easier to diagnose diseases.

The main cause is the gathering of synovial fluid at the back of the knee and can be triggered by either injury or stress from Arthritis.


Aside from infectious Arthritis, there are other possible infection types causing posterior knee pain as well, including:

– Bone infection (osteomyelitis.)

– Skin infection (cellulitis.)

– Infection of one of the fluid-sacs known as bursae (septic bursitis.)

All of these infections come with their unique causes and symptoms but redness, heat, swelling and pain are the most common regardless of the type of infection causing them.

A Tumor

While it is quite rare for knee pain to be a result of a tumor, it can definitely still occur near the knee in either its malignant ot benign form.

Here are the 3 types of cancer that can cause pain behind the knee:

– Liposarcoma is a type of cancer that grows in the fat tissue, including behind the knee.

– Osteosarcoma can be found in the long bones of the leg.

– Synovial sarcoma, which is a misnamed cancer as it does not actually occur in synovial fluid but in the large joints instead.


It’s no surprise that any type of tendon, ligament, muscle or connective tissue injury can also lead to posterior knee pain.

Injuries can be caused or worsened by overuse of the affected area.

Three of the most common injuries causing pain behind the knee are meniscus tears, Hamstring injuries, and injuries to the posterior cruciate ligament (PCL).

Deep Vein Thrombosis

DVT is caused by the occurrence of a blood clot deep in a vein and is more often found in the thigh, pelvis or calf but can end up causing pain anywhere in one’s leg, including, you guessed it, the back of the knee!

It is important to specify that this can be a life threatening condition.

After all, if the clot manages to break loose and travel to the lungs, it can end up blocking the blood flow.

Instead, if it remains in place, it can really damage the veins’ valves, causing a lot of swelling, pain, ulcers and other serious symptoms. In order to properly diagnose and treat this condition, it is advised to seek out a vein specialist in Dallas.

When is it recommended to see a doctor if you experience posterior knee pain?

If you have any signs of infection, severe pain or DVT, you should visit a medical specialist immediately but most other knee pain calls for an urgent check-up as well.

In fact, even if your symptoms seem less urgent, a talk with your doctor is still the best bet, although you can still manage the pain with some over-the-counter pills such as ibuprofen in the meantime.

If you’ve experienced an injury around the area, it is recommended that you encourage the healing process by resting, icing the knee, applying compresses and elevating the leg.


As you can imagine, treatment for behind the knee pain is greatly dependent on the diagnosis.

So, while Arthritis or damage from wear and tear or injury can be treated with medications, rest, injections, physical therapy or even surgery, some Baker’s cysts go away on their own although some cysts need to be drained or at least treated in other ways.

DVT, tumors or infections require individualized treatment following a correct diagnosis.

All in all, keep in mind that, while useful to know, this information should be taken with a grain of salt.

Just because you may be experiencing posterior knee pain, it does not necessarily mean you have any one of these conditions.

There is a multitude of other pathologies and factors that can cause very similar symptoms.

Regardless, it should still be a helpful starting point in hopefully understanding what you may be dealing with as well as a source of helpful products bound to alleviate your pain before or after meeting up with your physician.
