Pain Behind Knee

Pain Behind Knee is a common complaint among all ages. The most common causes include sports injuries and signs of wear of the knee joint. Less common, but especially dangerous or severe, are leg vein thrombosis and herniated discs.

If the symptoms are so lengthy or intense that they involve a visit to the doctor, he may make a suspected diagnosis by questioning various circumstances (such as the patient’s physical habits, time of onset and the exact location of the pain) and physical function tests Procedure must be confirmed.

Pain Behind Knee

The possible causes of Pain Behind Knee can be divided into traumatic (injury-related), degenerative (wear-related) and internal (internal causes).Injury-related causes are the most common triggers for Pain Behind Knee in younger patients. The pain usually occurs suddenly and in connection with an unfavorable movement in the knee joint, such as during sports.

Pain Behind Knee

The more clearly the knee pain is limited to the region of the Behind Knee, the greater the suspicion of damage to one or both menisci in the knee joint. In the menisci ( Menisci) are cartilage buffer discs that may be affected by twisting or buckling of the knee. Depending on the affected meniscus (in each knee there is an inner and outer), the pain is felt accordingly on the inner or outer Behind Knee.

Obviously, knee pain caused by wear and tear is more likely to occur in elderly patients. The most common trigger here is the so-called Baker cyst. This is a sagging of the joint capsule filled with synovial fluid, which may result from continuous irritation of the knee joint (due to osteoarthritis or unusually high exercise stress, for example).

The most important internal cause is the leg vein thrombosis, which is extremely rarely the trigger of popliteal pain, but due to its dangerousness should be at least in the back of the head. Due to the interplay of various factors (prolonged immobilization eg in the airplane, intake of contraceptives, genetic predisposition etc.), the blood coagulates into leg veins and the Behind Knee is one of the most common places for this event. In the worst case, this clot is flushed out into the lungs and lead to a pulmonary embolism.

Other less common causes of knee pain include anatomical compression of the popliteal or popliteal artery, tendinitis of the hamstring, or herniated disc.

Pain behind Knee symptoms

If the Pain Behind Knee is based on a traumatic cause, swelling and overheating of the knee often occur within a short time after the accident. The knee is limited in its mobility and prepares in case of meniscus damage, especially in rotational movements severe Pain Behind Knee.

If a Baker cyst is the cause of the pain, it is usually possible to feel a bump in the Behind Knee (as opposed to the traumatic causes, where the swelling is more likely to involve the entire knee). Again, it may cause disability of the mobility of the knee joint. The pain develops rather continuously over a longer period of time and it is not a specific accident event as a trigger remembered.

In leg vein thrombosis, the Pain Behind Knee and lower leg is usually accompanied by a feeling of pressure. Compared to the other leg, the affected leg may appear thicker, warmer and more reddened. If these observations are present, a doctor should be consulted immediately, who can estimate the risk of thrombosis based on the patient’s history (longer flight, previous illnesses, medication, etc.) and if necessary take further diagnostic measures.

In the case of a disc herniation, the Pain Behind Knee is more likely to be a secondary finding, as the pain from the back can radiate along the affected nerve to the back of the thigh and just into the Behind Knee and lower leg. In more severe cases, in addition to the described radiating pain also nerve failures occur, so paralysis or numbness on the legs or in the pubic area.

Pain Behind Knee Diagnosis

The search for a diagnosis begins with the medical history, that is, a detailed interview with the patient. Here should be systematically queried, where exactly the pain is, whether accompanying symptoms (such as swelling, restriction of movement, etc.) was noticed, whether the pain has occurred suddenly or continuously increasing and how strong is the regular physical stress.

In suspected venous thrombosis, in addition, the clarification of triggering factors such as prolonged immobilization (eg during air travel), nicotine consumption or medication intake is of great importance. Often the doctor can already use these findings to make a suspected diagnosis.

Depending on the suspicion, further diagnostic measures may be initiated, if necessary. Suspicion of meniscal damage can be confirmed, for example, by special functional tests ( Steinmann sign ) and ultimately confirmed or excluded by an MRI scan. Also, wear-related processes such as the Baker cyst are subject to this algorithm from anamnesis, physical examination and, where appropriate, subsequent imaging in the form of ultrasound examination or MRI scans.

In the back of the knee radiating back pain and the consequent suspicion of a herniated disc, MRI technique is also used. However, an imaging of the spine is done here because the cause is there and the Pain Behind Knee also originate there, as the term “radiating” beautifully describes.

In order to rule out a dangerous vein thrombosis, follows the history of a physical examination in which the doctor on circumferential differences between the two legs, overheating and redness of the lower leg respects. If necessary, then an ultrasound examination or a contrast agent X-ray examination of the leg vessels may be required.

Pain Behind Knee Duration

Obviously, due to the many possible causes of Pain Behind Knee, it is not possible to give general information on the duration of the pain. Depending on the trigger, however, some guidelines can be formulated.

In the case of meniscal injuries due to an accident, operative treatment is usually necessary. However, this is a relatively minor procedure in which the meniscus is either sewn together or partially removed. With regard to the following on the OP treatment period, the instructions of the surgeon should be followed, but which turn out to be surprisingly short: Frequently, after just 2 weeks, light running training again be included and after 4-6 weeks full fitness for exercise can be achieved.

If the pain is due to a wear-related cause, the duration of the protection is sometimes extended considerably but has a large individual spectrum. In general, it can be said that until the complete disappearance of the pain, exercise is completely omitted and thereafter only slowly and gradually should be increased again. If there are concomitant diseases that favor the irritation reaction of the knee joint (eg osteoarthritis, older meniscal or ligament tears), consideration should be given to treating them as far as possible and only then to resume sports activities.

Pain Behind Knee in the popliteal region while jogging

Pain behind the knee that occurs during or after running, is a very common phenomenon described especially in amateur sports, which only recently an intensive running newly added (re). If the pain is reliably declining overnight and only minimally or no longer perceptible on non-sporting days, the all-clear can be given first and the pain can be regarded as a simple expression of the unusually high load on the knee joint.

In this case, even a temporary reduction in the amount of exercise can provide for a complete disappearance of the symptoms, after which the intensity can be slowly increased gradually again.

If the pain persists for weeks despite consistent or even reduced training scope or even becoming stronger, inflammation of the tendons in the popliteal region is likely. In particular, when the pain is accompanied by a knee swelling and overheating, an orthopedist should be consulted.

This can confirm the suspicion and investigate whether certain concomitant diseases (older meniscus or torn ligaments, deformity of the knee joint, etc.) are present, which make the knee more susceptible to symptoms of congestion.

In principle, it is not recommended to combat pain with painkillers such as ibuprofen or diclofenac in order to be able to maintain the training period. The Pain Behind Knee is to be regarded as a warning signal of the knee joint, which should be considered. Of course, the painkillers mentioned above can be used for severe complaints, but this should also mean that the physical stress is greatly reduced or completely suspended for a certain period of time.

Pain Behind Knee after exercise

If there is Pain Behind Knee after exercise, it is necessary to differentiate between overwork due to the sport being performed or injury to ligament or muscle structures in the Behind Knee. Often the pain has a harmless cause.

Typical sports that cause irritation to the tendons that attach to the knee are long-distance running and professional cycling. Both sports are characterized by a constant use of the upper and lower leg musculature, whereby in particular the knee sliders on the thigh cause pain in the back of the knee when overloaded. But also when skiing injuries occur repeatedly on the knee, which here usually no overloads but strains or serious injuries such as meniscus damage occur.

Due to the strong leverage effect of skiing through the extension of the leg by the skis, in the case of supports in which the knee is twisted is, the menisci in the knee joint suffer damage. An injury to the menisci then causes a pain that radiates into the Behind Knee. Regardless of whether an overstress or an injury in the area of the Behind Knee has occurred, the sport should be stopped immediately and training should be started only after the symptoms have cleared up.

After jogging, Pain Behind Knee usually occurs due to an overload of the so-called is chiocrural musculature. This is located on the back of the thigh. This muscle group includes the biceps femoris muscle, the semitendinosus muscle, and the semimembranosus muscle. All three muscles move from the thigh coming on the outsides of the popliteal space and put on the head of the lower leg. Thus, they can for a flexion in the knee joint take care and are stressed during jogging.

The tendons of these muscles may be irritated at first, but with strong irritation, inflammation or even tearing of the tendons is possible. From the stage of the inflammation, a training break of approximately 6 weeks is to be held, until a complete annealing took place and the training can be taken up again without danger.

After an overload or over-stretching of the calf, for example, can occur in the knee after running in pain, as the two-headed muscle gastrocnemius, which shapes the calf, rises in the knee. If this muscle is overstretched or not sufficiently stretched after runningThis easily causes Pain Behind Knee after running.
The cause of the complaints can also be triggered by poor footwear or misalignments of the leg axes. In this case, deposits can help. In the acute phase of pain, sparing, the elevation of the leg and cooling are beneficial.

irritation of the sciatic nerve can also cause Pain Behind Knee after walking, as this nerve with its terminal branches runs directly through the Behind Knee. If you stretch your knee too much while running, it can lead to compression and damage to the nerve, especially if you want to start as an inexperienced runner directly.

Pain Behind Knee after prolonged sitting

If the Pain Behind Knee occurs after prolonged sitting (eg in an airplane), this may be the first indication of a vein thrombosis. The lower leg of the affected leg then often turns out to be overheated and swollen (see above). The doctor can then assess the risk of such a thrombosis with targeted inquiries for other triggering factors and if necessary initiate further diagnostic steps.

Cartilage damage under the kneecap may be another cause of popliteal pain after knee-jointed sitting. Typical of this is that the knee initially feels stiff and painful, for example, after a long journey by car as a passenger in the back seat or after a visit to the cinema, but the knee “runs in” after a few steps and the pain disappears. An orthopedist can confirm the suspicion by means of functional tests and initiate imaging measures such as an X-ray or MRI examination for confirmation.

Pain Behind Knee after stretching

If the pain in the popliteal space occurs after stretching, the reason may be an overload or a strain in the muscle. Most likely, there is a strain in the two-headed gastrocnemius muscle, the soleus muscle, or the plantar plantus . These three muscles form the calf and have their origin in the area of the Behind Knee. If there is a painful hyperextension or a strain of the muscle, further strain (in this case after stretching and thus stretching of the muscles) may cause Pain Behind Knee.

Pain Behind Knee after pregnancy

In addition to smoking and taking the pill, pregnancy is also a risk factor for the development of a leg vein thrombosis. If pain occurs in the Behind Knee after pregnancy, this possibility should be kept in mind at least. If the pain is accompanied by overheating and swelling of the lower leg of the affected leg, a leg vein thrombosis is more likely and should be clarified immediately by a doctor.

In contrast, however, it should also be mentioned that the expectant mother gains an average of about 10 kilograms of weight during pregnancy, which represents an unusually high load for the knee joints. As a result, overuse of the knees becomes more common during pregnancy, which can cause pain very similar to those in leg vein thrombosis.

Pain Behind Knee after pregnancy

In addition to smoking and taking the pill, pregnancy is also a risk factor for the development of a leg vein thrombosis. If pain occurs in the Behind Knee after pregnancy, this possibility should be kept in mind at least. If the pain is accompanied by overheating and swelling of the lower leg of the affected leg, a leg vein thrombosis is more likely and should be clarified immediately by a doctor.

Pain Behind Knee in children

Children can complain of pain in their legs, especially at kindergarten or elementary school age. The pain is then usually localized in the popliteal, calf or hip.

There are two important causes:

First, it may be a so-called growth pain, the cause of which is unclear. It is most likely to occur in children between the ages of two and eight, usually at night, and only for a short time.

On the other hand, in children, especially in the growth phase, epiphyseolysis is a possible cause of Pain Behind Knee. This is a detachment of the growth plate, so that, depending on the extent of the disease, the epiphysis partially or completely slips off the bone – in the region of the knee from the tibia. This not only causes pain, but there is also the risk of growth disorders, as the normal bone growth is interrupted at the growth gap.

This condition can occur both after injury and for no apparent reason, Especially in the latter case, there is a risk of not taking the child’s complaints seriously. In stages, I and II according to Aitken immobilization of the affected leg is necessary for stages III and IV wires for fixing the epiphysis to the bone are absolutely necessary to ensure proper growth of the child’s length.

But how does one differentiate whether it is growing pains or a serious illness? A clear distinction is of course not possible without a doctor. However, there are some symptoms that clearly speak for a cause other than growth. If the child has very severe, long-lasting pain(more than 15 minutes) in combination with a cold-free fever, this is more likely to indicate an infection or other diseases than growth pain. In addition, redness and swelling in the joints speak against a growth pain.

What can one do against these pains? You can put the child a hot water bottle on the affected areas. Also targeted massages or the administration of a light painkiller, such as ibuprofen, can help. But it is easy to discuss the procedure with a doctor. Growth pains are usually something normal and physiological and require no therapy. However, it should always be clarified whether something else is behind the pain.

Other conceivable causes of Pain Behind Knee are joint misalignments in the leg children, which may be congenital or acquired. Of course, the pain can also be located elsewhere on the leg (eg in the ankle ), depending on the malposition.

Pain Behind Knee in the thigh

The musculature of the thigh is at the boundary of the knee involved (see ” Bicepssehnentendinose “). Therefore, diseases, strains, and tears of the thigh muscles, especially the biceps femoris, can cause back Pain Behind Knee. This pain can radiate into the thigh.

Pain Behind Kneein the outer Behind Knee

In the outer area of the Behind Knee, pain usually occurs with irritation or injury to the ligament and tendon structures of the knee, but injuries to the menisci and the joint capsule also cause these symptoms if the K is never twisted. Although the outer meniscus does not tear as fast as the inner meniscus, with a wrong rotational movement, it can come through a crack to pain in the popliteal space on the outside.

The following reasons may be present for pain in the outer Behind Knee:

Both a tear of the inner band and the outer band cause back pain in the knees and occur in Rotationsstraumata at the knee, in which the lower leg is excessively twisted against the thigh. The rupture of the ligaments may be palpable, but most of all cause pain.

The tearing of the inner ligament typically occurs in conjunction with a tear of the anterior cruciate ligament and injury to the inner meniscus, causing the knee to become generally unstable. Both bands can also be used in sports such as skiing or horseback riding overloaded and thereby cause pain in the outside of the Behind Knee. By sparing the congestive pain improves within days.

An injury to the inner or outer meniscus causes a pressure pain over the joint space of the knee, which radiates however also into the outer back of the knee and occurs in particular with a bend of the knee. Also, a degeneration (occurs especially in old age) or a lesion of the external meniscus leads to pain in the popliteal space outside.

In stretched leg trauma, the outer band, the capsule, and the posterior cruciate ligament are more frequently damaged. All three structures often result in a lighter initial pain in the outer Behind Knee, which increases with time and spreads.

The muscle-tendon – transition of the hamstrings, which leads from the back of the thigh to the outsides of the knee, can be caused by extensive training overloads, which then also provide pain in the outer Behind Knee. Likewise, the popliteus muscle runs in the Behind Knee and can lead to pain in the outer Behind Knee in case of overload or injury. These occur in particular during downhill running due to the stress on the muscle, whereby in some cases the symptoms can improve again.

Distinguishing between ligament or muscle overload and seriously injuring knee structures is very important to avoid consequential damage. If protection, cooling, and high-altitude storage do not improve significantly, the cause of the complaints must be clarified.

Another reason for pain in the knee outside, a Baker cyst (see below: popliteal cyst ) be. This is a sign of wear and tear, especially in elderly patients. The knee swells strongly and an extension causes Pain Behind Knee, with the pain being localized either externally or internally depending on the appearance of the cyst.

Both overloading and injuries of structures at the knee should be on a strict conservation taken in order not to worsen the condition and promote healing.

A clarification of the complaints is through:

  • orthopedic tests
  • X-rays and
  • the implementation of an MRI


Pain in the Behind Knee and calf

If the Pain Behind Knee, a radiation of discomfort in the calf is possible. Conversely, pain from the calf can also radiate into the Behind Knee. The following possible causes may exist:

  • thrombosis
  • Baker Cyst
  • Overload of the gastrocnemius muscle
  • wrong footwear while running
  • Compression/injury of the tibial nerve
  • Compression of the knee

If the pain radiates from the calf to the Behind Knee, there may be a thrombosis in the leg. Thrombosis is a vascular disease with a blood clot in the venous vasculature, especially the deep veins of the leg. The blood clot can be transported on to the heart or lungs, triggering a life-threatening pulmonary embolism, for example.

In a multi-agent thrombosis, vessels are affected, which supply both calf and Behind Knee and thigh. As a result, there may be a pain in any of these areas, which may also radiate to the surrounding tissues. More common, however, is the pain in the direction of the foot, as it backs up the blood, which can no longer flow away to the body center through the vascular occlusion. In most cases, there is also a knee swelling and one or both calves. If you suspect a thrombosis you should urgently consult a doctor.

A possible cause of calf pain originating from the Behind Knee may be a ruptured baker’s cyst (see below). This is a protuberance at the weakest point of the posterior capsule of the knee joint. Often the cause of a Baker’s cyst is an injury in the knee joint that leads to chronic inflammation. The inflammation, in turn, causes a fluid formation in the joint, which leads to the formation of a Bakerzyste by the resulting pressure. If the pressure is too great, the joint capsule tears. The joint fluid empties into the deeper calf following gravity. There, the run-in liquid causes swelling and pressure pain because the compartments of the lower leg are stretched excessively.

If there is a Pain Behind Knee, the gastrocnemius muscle (originating from the Behind Knee) can also be overloaded and starts in the Achilles tendon in the heel area.

If you wear the wrong footwear when running, it can also cause Pain Behind Knee.

Another possible cause of simultaneous pain in the popliteal and calf is an injury or compression of the tibial nerve. This nerve lies on the surface of the Behind Knee and runs further into the calf up to the Fussaußenrist. It can be damaged by a direct injury, but also by a hemorrhage or an articular effusion, which leads to nerve irritation through compression. Even if the original injury to the knee has healed, irritation of the nerve may be the cause, causing pain in the calf.

In very intense training and using muscle-building supplements, it is possible that the rapid increase in the size of the muscles of the thigh and lower leg causes compression of the popliteal artery, which is located in the Behind Knee. Since this vessel supplies the calf muscles with blood, for example, the squashing of this vessel in the squat can cause a deficiency in the area of the calf and cause a so-called ischemic pain due to blood deficiency.

Pain in the calf

Calf pain often feels like a piercing pain coming from the depths. However, these pains, especially the chronic, are often superficial. They usually result from tension in the muscles, their fascia or the connective tissue. These tensions can be felt from the outside as hardening. The pain increases with certain movements, such as when kneeling or jogging.

The Pain Behind Knee can be explained by the course of the calf muscles. Important here is the large musculus triceps surae, which forms the vault of the calf. It consists of a superficial gastrocnemius muscle and a deep soleus muscle. The gastrocnemius muscle is a two-headed muscle originating at the lower edge of the thighbone, called the epicondylar of the femur, which attaches to the Achilles tendon. With his two heads, he limits the Behind Knee to the right and left, Pain in this muscle or even at its origins radiate so quickly into the Behind Knee or arise even in this.

Almost always movement restrictions are observed. The stretching of the knee is difficult, but also the rolling of the feet, the bending, and stretching of the toes, the bending and stretching of the ankle and the pronation and supination of the foot.
