Why does my knee swell up?
Many people complain about swelling of the knee. After all, do not forget that it is on the knee joint is the main load during walking. Edema and pain can be caused by completely different causes, from injuries to infectious diseases.
Knee swelling due to
injury Often the cause of edema is acute damage to the knee joint, which are possible, for example, with a strong impact or fall. As a rule, the trauma is accompanied by a sharp pain, the intensity of which can be weakened, as well as the presence of a hematoma and edema. In any case, the mechanical injury of the knee joint is fraught with:
- with sprains or tears of tendons and ligaments;
- damage to the meniscus;
- fracture of patella, lower part of tibia or upper part of lower leg;
- knee calyx displacement;
- dislocation of the knee joint.
It is worth noting that the knee swells for each of the above injuries. Therefore, the victim must be immediately sent to the hospital - without medical assistance here can hardly be dispensed with.
Why does my knee swell up? The most common diseases
Sometimes it happens that swelling of the knee joint appears against the background of general health without mechanical trauma. Of course, this phenomenon can signal the mass of a variety of diseases:
- Bursitis - a fairly common disease, accompanied by inflammation of synovial bags( bursa).The inflammatory process can be caused by trauma, stroke, persistent physical stress, and also by infection. With such a problem, most often encounter sportsmen, in particular cyclists, jumpers, football players. The disease is accompanied by pain, fever and accumulation of fluid inside the joint.
- If the knee is red and swollen, this may indicate the development of arthritis. Such a disease can occur under the influence of various factors, including trauma, infection, hypothermia, physical activity, etc.
- In some cases, edema can be explained by the presence of free bodies in the cavity of the joint bag. Such a phenomenon can be the result of both trauma( for example, a meniscus fracture or fracture) and some diseases, including osteoarthritis, chondromatosis. In any case, the patient needs help, since the presence of loose bodies is often accompanied by blockade of the knee joint.
- If the knee is swollen from the inside, then this may indicate a so-called "Baker's cyst", which is nothing more than a fluid cluster in the popliteal region.
- Be sure to pay attention to the attendant symptoms - whether there is pain, redness of the skin, a rise in temperature, as this is important for the diagnostic process.
In any case, edema of the knee is a rather serious problem. It is almost impossible to diagnose such a condition and determine the cause of the violation independently. Therefore, if there is swelling in the knee area, it is best to go straight to the hospital, where the doctor will examine the leg, prescribe tests and X-ray research - this is the only way to find out the nature of the pathology, which, of course, directly affects the chosen method of treatment.
A heavily swollen knee is the result of a trauma or a symptom of a dangerous disease? How to understand what exactly caused this phenomenon? A thorough medical diagnosis will help to answer these questions.
However, there are concomitant symptoms that you simply can not miss. They will help determine the causes of this unpleasant phenomenon. Denote the most common causes of the formation of painful swelling in the knees.
Common causes of
The formation of pain and swelling in this area can be due to a number of reasons. Sometimes this condition indicates the presence of serious illnesses, such as gout or osteoporosis. In some cases, a swollen, painful knee is a manifestation of the resulting injury. Let us analyze the most common causes of this problem.
The period of exacerbation of this chronic disease can relate to frequent causes, due to which the knee swells and hurts. Sometimes this condition is accompanied by redness. The pain is paroxysmal acute. An increase in the local temperature is possible.
The cause of gout is the delay in the joints of crystals of uric acid. Because of this, there is inflammation and, accordingly, pain. The increase in uric acid in the blood can speak of a violation of the functionality of the kidneys. Men suffer from gout more often than women. And this trend persists for patients of all age groups.
Another common cause, due to the development of which the person has swollen knee - osteoporosis. This disease is a decrease in bone density because of what it becomes susceptible to fractures and cracks.
The reason for this phenomenon is the reduction of the amount of mineral substances, such as phosphorus and calcium, simultaneously in all 220 bones of the human body. This is due to metabolic disorders or hormonal balance.
The danger of osteoporosis is that with the development of this disease, the vertebral bodies suffer, their fracture occurs and the person feels unbearable pain. When a bone fracture occurs, a relapse occurs. Bone is poorly restored, becomes prone to repeated fractures. As a result, the patient has to tolerate the symptoms of puffiness and pain all the time.
Inflammation of the tendons also serves as an answer to the question of why the knee is swollen and aching. Painful sensations are manifested mainly in the performance of movements and are of an intense nature. This disease causes severe swelling.
Victims of tendonitis of the knee joint are more often than others:
- children and adolescents;
- people whose work is associated with constant physical exertion;
- faces of middle and old age.
The causes of inflammation of the knee tendons are of various origins. Tendonitis can occur due to infections in the surrounding tendon tissues, calcium metabolism disorders, chronic inflammatory diseases, as well as a constant load on the knee joint.
Damage of knee ligaments
Solve the problem, why the knee swelling will help the examination of ligaments. Rupture or sprain of ligaments is also a common cause of swelling and pain. During this kind of damage, it becomes painful for a person to step on an injured limb. Even during sleep the patient can not unbend the suffering leg.
Causes of rupture or sprain of the ligaments can be a sharp jerk of the leg during motor activity and a change in the position of the joint, that is, its exit, as a result of a slippery surface. Damage to the knee ligaments is characteristic of professional athletes and people with weak or ligamentous ligaments.
Damage to the skin, muscles and periosteum of the knee is called a bruise. In this injury, edema and pain in the knee joint are also possible. The pain in this case is intense. Also for this type of injury, a concomitant symptom is a bruise.
The cause of the injury is the pressing of soft tissues against the bone, as a result of a fall or blow by a blunt object. A bruise can cause serious illnesses like hemarthrosis. Therefore bruises must be treated on time.
Edema in the knees and aching pain is characterized by rheumatoid arthritis. During rheumatoid arthritis, inflammation develops, which can contribute to the destruction of articular cartilage. This type of arthritis can appear at any age. And the disease develops immediately in both knee joints.
A person suffering from rheumatoid arthritis experiences problems with flexion and extension of the legs. The pain intensifies during walking, moving up the stairs, as well as when standing on your knees. The causes of arthritis are malfunctions in the immune system, disturbances in the work of the exchange between articular tissues, which contribute to the renewal of the joint.
Than to treat these illnesses and how to eliminate a pain and puffiness in a lap? Consider the most effective methods of treating the knee joint.
Methods of treatment
There are several ways to eliminate uncomfortable symptoms in the knees, with traumas or due to the development of various diseases.
- Drug treatment - is directed not only to the elimination of symptoms, but also to a full recovery.
- Surgical treatment, combining full-fledged operations and little-invasive techniques.
- Physiotherapy treatment - the use of a variety of ways to get rid of the symptoms.
This kind of therapy is aimed at stopping the destructive processes of cartilage tissue and restoring the joint after a trauma or a disease that has arisen. Drug therapy includes such types of drugs:
- non-steroidal anti-inflammatory drugs;
- steroid hormones;
- bada and vitamin complexes.

The knee is swollen and sore: what to do, treatment, causes, folk remedies
The reasons for which the knee is swollen and sore can be a multitude. However, whatever the reasons for discomfort in the knee joint, the main question arises - what to do? Swollen knees are a serious reason to think about your own health.
As a matter of fact, a tumor in the region of the knee is a symptom of the pathology of the musculoskeletal system. Most often its cause are: trauma, gout, bursitis, osteoporosis and other diseases.
The knee joint on all sides is covered with an articular bag that has an outer and an inner shell.
On the outer shells of the articular bag are pouches with mucus. The human body is arranged in such a way that all the moving parts of the skeleton continuously rub against each other. And these bags with slime just do help to reduce friction and facilitate movement. It can be said that a slimy bag is a kind of shock absorber with a liquid, located between surfaces rubbing between each other. Thanks to the bags, the process of friction is painless and without damage.
Knees can swell differently. Sometimes the tumor is almost invisible, and in some cases it reaches huge proportions, rising above the knee level by 7-8 cm.
The most common causes of edema of the knee
Most often the knee swells and hurts because of the following reasons:
- tendonitis( inflammation intendons).Tendons are thick fibers of connective tissue. With the help of these fibers, the muscles are attached to the bones. When the tendons are injured or inflamed, the knee begins to ache and swell;
- knee ligament injury. In the knee area, severe swelling and severe pain can occur due to stretching or rupturing of ligaments;
- knee injury, usually accompanied by redness, swelling and pain during movements;
- osteoporosis of the knee is accompanied by different degrees of pain and swelling;
- displacement of the patella is very often accompanied by discomfort and swelling;
- septic arthritis is manifested by sharp pains, redness and even febrile condition;
- rheumatoid arthritis manifests itself as a swollen knee and aching pain;
- bursitis or inflammation of the joint bag. This disease manifests itself with pronounced edema and severe pain when trying to bend a painful leg in the knee;
- gout. If the cause of the tumor lies in this disease, the knee can periodically swell and hurt for several days, and then, suddenly subside, and so on until the next time.

Often, with knee injuries, athletes and people who lead an active lifestyle face. The sensations arising in the damaged joint are unpleasant, often it is necessary to get out of the schedule of trainings. Which is especially unpleasant. However, one of the most important rules for knee injuries is not to stop moving. Even in cases where the knee area has been subjected to surgical intervention, it is necessary to engage in active rehabilitation of the affected joint.
Begins recovery after illness with the most minimal loads and simple and short physical exercises. After all, the initial task is to try to return the injured muscles as soon as possible back to the system. Forcing the muscles to work, you can regain mobility of the joint and the ability to fully move.
During examination of the problem knee joint, the doctor may consider it necessary to appoint an MRI or CT scan( computerized tomography), as well as an X-ray. If a specialist has a suspicion of having an infection - then you will have to donate blood for analysis. In some cases, it is possible to take a joint puncture. Naturally, the treatment depends entirely on the diagnosis established by the doctor.
Of course, no one can protect himself from the possibility of getting a knee injury. However, there is a category of people who, for various reasons, are at risk:
- are those who are obese. People who are overweight are more likely to suffer from pain in the knee area, since it is the feet that account for the bulk of the body weight;
- those who constantly face high physical stress;
- women who are over 40;
- people who, by virtue of their activities or for other reasons, lead a sedentary lifestyle. These people have a serious lack of muscle flexibility;
- people with some anatomical features, for example, with flat feet.
If at least one of the above risk factors is relevant to you, try to take it as a rule never to overload your own knees.
Those who are overweight should think about the correction of nutrition and lifestyle.

Folk remedies for knee pain
Folk medicine knows about everything and will support everyone who comes to her for help. So, and treatment of various diseases of the knee joint is not alien to folk remedies and "grandmother's" recipes.
For the removal of edema and pain, warm baths are shown from the herb of saber, eucalyptus, mint, fir;
If the treating doctor is not prohibited, it is useful to knead the knee in circular motions using such creams as "Troxevasin", "Sofya", etc.;
It is necessary to take in equal quantities the flowers of horse chestnut, leaves of plantain, and white cabbage. All this is triturated to a homogeneous mass and superimposed on the diseased knee as a compress( under the film) for 4-6 hours.
The internal state of the patient is very important. Of course, a large knee and restrictions in movement can make anyone, but constant irritation can become a significant barrier to recovery. Therefore, try to tune in to a positive mood. Relaxation and auto-training are considered useful for the patient. Avoid unpleasant communication and stressful situations.
Physical exercises are necessary for the patient's joint to regain its former mobility. However, before proceeding to the exercises, it is necessary to obtain the permission of the attending physician. So, if there are no contraindications, you should start to do a daily stretching of the sick leg, gradually increasing the load on it.
Lie on your back, on the floor, try to pull forward your aching leg, stretching your socks, count to 5. Then, relax and let your leg rest.
Lying on your back, on a hard surface, raise your leg with a sick joint above the floor level by 15 cm, try to make a stop motion "semicircle" in one and the other side. If this is easy for you, you can make several such movements, if not, then, for starters, one or two is enough.
Sitting on a chair, lean your back against the back of the piece of furniture and with your hands, spread your knees aside, then bring them together. You need to do this slowly.
The basic principles and rules for the prevention of knee diseases, as mentioned above, is the wise distribution of physical and sports load. It is very important to monitor your own weight.
Try to avoid such popular, but very harmful modern food, like chips, mayonnaise, sweet fizzy drinks, energy. Maximum exclude from your diet animal fats, sweet pastries, salty and very spicy dishes. Try daily to eat sour-milk products, poultry, sea fish, various seafood, vegetables, greens and fruits.
Pay attention to the shoes that you wear. As a rule, knee diseases are most often observed in women. One of the explanations for this is wearing shoes with heels. Therefore, it makes sense to abandon elegant shoes with stilettos in favor of shoes on a more comfortable sole if, for example, you plan to go to a store or park for a walk.
Daily gymnastics is very important. In extreme cases, take yourself for a walk at least to the store and back. Remember that the scourge of modern man - lack of mobility. And it is she who deprives many people of the ability to function fully.Find an orthopedist and make an appointment
All these injuries have differences in which a rheumatologist or surgeon can distinguish one from another.
So, with the dislocation of the knee, its deformation is observed. If, during a trauma, the shin becomes mobile, then we can talk about rupturing the ligaments of the knee joint. If the pain in the knee during extension is very strong, then, most likely, there was a meniscus damage.
How to treat knee injuries
In the presence of severe pain in a damaged knee injury, it will be necessary to resort to the use of pain medications. Suitable for this situation are aspirin, ibuprofen, paracetamol and others. When walking, it is better not to rely on an injured leg, use a cane or lean on a crutch.
If the knee is swollen due to a minor bruise, to relieve the pain it will be enough to apply a tight bandage and then, as the pain subsides, do exercises to restore the mobility of the leg.
If you find a dislocation of the knee joint when you see a doctor, you will have to suffer pain when you tweak it. Further, the recommendations for recovery will be similar to the treatment of knee injuries.
In the case of diagnosing a meniscus injury or torn ligaments of the knee joint, one must resort to a surgical procedure. After this, prescribe the use of anti-inflammatory drugs and antibiotics to avoid the development of infection.

From pharmacy drugs fights well with swelling, for example, the gel Troxevasin and the like.
Injuries of the knee should not be neglected, thinking that it will pass by itself. If the damage is not treated in time, there is a great risk of getting a more serious disease, for example, bursitis, which is a type of arthritis. When bursitis occurs inflammation of the joint bag, and treat this disease is much more difficult.
What if the swelling of the knee is caused by an insect bite?

For some time it is necessary to provide a damaged knee rest. This is important in order for the joint to recover, and it will prevent even more serious damage. It is necessary to raise the leg upwards, in order to reduce the flow of blood. If there is a suspicion of serious injury, you should see a doctor.
What if there was a bruise, knee swelling and pain? The biggest danger of a bruise is that the skin most often remains intact, there may be minor scratches or bruises. Do not forget that sometimes for all this may hide a fracture, with fragments or a mixture of bones. Even if he overgrows himself, it will lead to disability. Therefore, in order to avoid this, you need to undergo a survey.
There are symptoms that can help distinguish a bruise from fracture or dislocation:
- After a bruise, a sharp pain appears in the knee area. In the absence of serious damage, it passes after a while. However, with serious damage, it can build up, and swelling may increase.
- Skin over the affected knee becomes red, which is a sign of synovitis, which is a response to the damage.
- Another symptom is a tumor. Sometimes it can be observed that the joint has increased in volume. This is because liquid begins to accumulate in its cavity.
- One of the consequences of a bruise is hemarthrosis, which manifests itself as a hemorrhage into the joint cavity. With a strong internal bleeding, the joint increases in volume several times.
If the injury is severe, then there is a chance that the leg will lose mobility.
It is these symptoms that are characteristic of a bruise. If they do not disappear for a long time, then this can be a reason for anxiety and you need to see a doctor. The most frequent complication that occurs after a fall or stroke is the displacement inside the joint. Another complication is arthrosis of the knee joint.Back to the table of contents

What complications can be after a knee injury
A frivolous attitude towards a knee joint injury can lead to complications. That is why it is necessary to start treatment immediately, and in case of severe trauma you need to see a doctor. One of the complications is the fluid that accumulates in the joint. This process leads to a strong puffiness, and to an increase in the joint in size. The only way to cure this is by imposing gypsum, which leads to impaired mobility. Sometimes a puncture is required, which allows liquid to be eliminated.
The patella is very uncomfortable, so when you hit it you can easily get a dislocation or fracture. If you can not cure them in time, you can remain disabled. The most common complication is sprain or ligament rupture. One of the characteristic manifestations of stretching is the lack of the ability to stand on the foot. Movements become painful and difficult.
Upon impact, regardless of the degree of severity, often a meniscus is damaged. Meniscus is a small cartilaginous plate, which is located in the region of the knee joint. There are only two. If you do not provide medical assistance in time, this leads to the fact that the meniscus begins to gradually deteriorate. The consequences of this can be quite serious, and even disability can occur.
Knee edema very often can be associated with bursitis. Very often it leads to an increase in body temperature and is accompanied by severe pain. In the event that there is an infected wound, there is a risk of developing purulent bursitis, which can be cured only through surgery.
As you can see, a knee injury can lead to quite serious consequences, especially if it is not treated. If the symptoms of injury can not be eliminated at home, then you need to go to the clinic and be treated. Timely and correct treatment can help to avoid serious consequences.
