Ever thought about pain behind knee causes? I guess everyone at one point has done that. The challenge is that we do not seem to get the answers clear.

Pain behind the knee comes as a result of excess pressure mounted on the tendons that attach human hamstring muscles to the knee back.

It is therefore important that anyone involved in any strenuous activity especially running clearly understands what causes pain behind the knee.

Causes of pain behind the knee.

Dislocated knee cap

The knee cap also known as patella is a small bone that covers the front of the knee. It is important in ensuring adequate muscle balance and helps you move swiftly by carrying your body weight.

When it gets dislocated it slightly or completely moves out of its normal position. This dislocation is considered the most common pain behind knee causes as it causes knee swelling accompanied by unbearable pain. What causes knee cap dislocation? Dislocation of the knee cap does not result from any injury but is most commonly linked to a physical glitch in your legs.

Popliteal cyst

This is a condition whereby the knee cartilages are torn, and makes you feel pain behind the knee while bending or squatting. The pain gets worse since the torn cartilages provide alee way for fluids to fill the tendons. If at all the popliteal cyst bursts, blood accumulates in the knee joint and increases the pain. In addition this also disrupts normal blood flow coupled with swelling and redness of the leg.

Root cause of popliteal cyst

It results from underlying joint problems such as arthritis that makes the knee produce too much fluid. Women and children are more susceptible to popliteal cyst. Before embarking on treating popliteal cyst its important to establish and deal with the root cause first.

Hamstring injury

Hamstring comprises of tendons that makes up the space bordering the back of the knee. The hamstrings are considered very crucial in human mobility.

Hamstring injury symptoms and signs include bruises, swelling and weakness of the entire leg. It makes the knee painful when walking, jogging, jumping and even running.

Tumors

Tumors are common around the knee and cause severe pain behind the knees. These tumors lock the knee and can completely prevent mobility by creating a fracture, infection or even wound breakdown.

Bone tumors can be either benign or malignant. Benign tumors are non-cancerous while malignant tumors are cancerous and therefore life threatening. As such it is important to take the symptoms serious and seek immediate medical attention.

Deep vein thrombosis

This is another critical linked to pain behind knee causes and can be life threatening. Deep vein thrombosis is a blood clot in the leg and has similar symptoms with popliteal cyst. The condition is mostly common in adults aged 60 and above, however other people of all ages should be on the lookout. Deep vein thrombosis can completely block blood flow and in turn cause swelling, pain and tenderness, and redness of the skin.

Cause of deep vein thrombosis

Deep vein thrombosis can be caused by obesity, bed rest, fractures in the leg and too many blood cells that tend to thicken the blood and slows its flow.

Peripheral vascular disease

This condition is also known as arteriosclerosis or hardening of the arteries. Arteries are meant to supply the body organs with oxygen and nutrient rich blood from the heart. It leads to narrowing of the arteries as a result of accumulation of fat and cholesterol and therefore inhibits blood flow. When blood flow to the legs is limited the legs become itchy and painful and hence the resultant pain behind the knee.

Other pain behind knee causes can be linked to a persons health condition. Based on the ailment one is suffering from pain at the back of the knees can be experienced as a symptom of the disease. For instance you may experience blood clots in deep vein as a result of your family history, surgery, pregnancy and obesity.

Conclusion

It is no doubt that the knee is a very important and delicate part of the human body and should be treated cautiously. Ignoring pain behind the knee can lead to serious complications such as loss of mobility, disability, poor life quality and even pulmonary embolism that mature from deep vein thrombosis.
