Knee pain is one of the most common symptoms with which patients consult orthopedists and other specialists.Many people completely ignore the appearance of unpleasant sensations, considering them age-related and almost natural.But there are many reasons for pain in the knee joint, because it has a complex structure and is affected by a number of external and internal damaging factors.Some diseases are serious and require urgent treatment.
Who is more likely to injure the knee joints?
The knees are formed by several bones connected by muscles, ligaments and tendons.There are also 5 synovial bursae - membrane-lined cavities designed to protect the joint.Between the joints of the bones there are interarticular cartilages - menisci, which help the knee to move freely.Disruption of even one area of the knee joint leads to the appearance of unpleasant symptoms.
Pain in the knee joint occurs especially often in people with flat feet.This is a foot pathology that disrupts the shock absorbing abilities of the limbs.With age, increased loads on the joints cause their destruction and the development of inflammatory phenomena - pain syndrome appears.Different types of foot and lower leg deformities have similar consequences.
There are a number of factors under the influence of which knee pain appears more often:
- Overweight;
- Passive lifestyle;
- High sports loads;
- Diabetes mellitus;
- Vascular diseases;
- old age;
- Knee surgeries and injuries;
- Work with increased load on the legs.

The causes and treatment of knee pain vary widely, as does the severity of the sensation.If your knee hurts a lot, the cause may be an injury or an advanced stage of osteoarthritis, a severe inflammatory process.Sometimes the symptom becomes permanent, present even at rest, accompanied by swelling, redness of the skin and tingling.All these signs should warn a person and force him to visit a doctor.
Pain due to bruises on the knee
Among the traumatic causes of joint dysfunction, bruises are the most common.Why does my knee hurt if the symptoms were preceded by only a small bruise?Even a slight injury is accompanied by hemorrhage in the periarticular soft tissues and their swelling.As a result, nerve roots suffer and pain appears.
In more serious cases, the pain in the knee intensifies when bending and extending the leg, and the person stops moving due to sharp sensations in the joint.On palpation, you can notice swelling of the leg;it is hot to the touch.How to treat such an injury?You should contact a traumatologist, take an X-ray, follow all recommendations and provide rest for your leg.
Often the cause of pain in the knee joint after a banal bruise is traumatic hemarthrosis.This is an effusion of blood into the joint cavity, causing edema and swelling of the synovial membranes.As a result, the joint fills with blood and inflammation begins.Without proper treatment, an injury can result in the development of chronic arthrosis even at a young age.

Other types of knee injuries
If your leg hurts in the knee and an injury has contributed to these sensations, the reasons may lie in various injuries to the components of the joint.Here are the main ones:
- Meniscopathy.Represents a flattening or tear of the meniscus.Injuries are especially common among professional athletes, people involved in extreme sports, as well as household injuries.A person feels that the knee is very painful, the nature of the sensations is piercing, like a dagger, the joint loses mobility for some time.
- Ligament damage.A tear (sprain) of the ligaments occurs when the leg is twisted, after a jump or when the limb is stretched in an unnatural position.A sharp pain appears, the leg swells, the position of the joint changes, it becomes loose.
- Cruciate ligament rupture.Since these ligaments are located inside the joint, damage often leads to bleeding in the knee cavity.Only one needle will help pump the blood and make an accurate diagnosis.
Painful pain in the knee joint sometimes accompanies chronic dislocations of the patella.Without treatment of the acute injury, in a number of patients the dislocation becomes chronic and causes regular relapses.In children, this pathology causes an X-shaped curvature of the leg and leads to serious impairment of its function.Sometimes the pathology affects the knees on both legs.

Inflammatory diseases of the knees
Often, standard treatment for knee pain is ineffective.In this case, it may not be the joint itself that is affected, but the surrounding soft tissue.Thus, tendonitis or tendon inflammation can be caused by increased loads on the limb, past leg injuries, allergies, drug reactions, etc.With this disease, the knee joint hurts, as a rule, during the day or in the evening;the pain subsides at night.In the acute phase, joint mobility is very limited, the syndrome is continuous and cannot be treated with ointments and creams.Sharp sensations are also observed during palpation of the lateral part of the knee.
If your knees hurt regularly, the symptom worsens after hypothermia, the cause may be synovitis - inflammation of the synovial membranes.An inflammatory exudate appears inside the joint, which causes cracking and pain.The causes of the pathology are different:
- Autoimmune diseases;
- Metabolic diseases;
- Past traumas;
- Arthrosis.
Another "popular" disease that causes pain in the knees is bursitis.It occurs when the bursa (joint capsule) becomes inflamed.In addition to pain, redness, swelling and increased sensitivity of the patella area are observed.If you do not clarify in time how to treat bursitis, it almost always becomes chronic.

Neoplasms of the knee joint area
Malignant tumors of this localization are rare;the pain syndrome is characteristic for them only in the very late stage.Most often, painful pain in the knee joint is characteristic of benign formations:
- Baker's cyst.This tumor appears under the knee, on its back surface.In appearance, the skin over the cyst is normal, not inflamed;when bending over, there may be no swelling at all.In a standing position, a clearly defined, soft, elastic formation appears at the site of the cyst.Appears after a unilateral knee injury or cartilage damage.Very often the cyst accompanies chronic synovitis, arthrosis, rheumatoid arthritis.Large cysts cause not only pain in the knee, but also serious limitation of limb mobility.Due to the compression of blood vessels and nerves, other symptoms include cold skin, paleness, goose bumps and numbness.
- Meniscus cyst.Appears in the outer or inner meniscus when a fluid cavity is located inside the cartilage.In this case, the knees hurt after high loads or at the end of the day.Large cysts can be seen on the lateral part of the joint, small ones are visible only with ultrasound or x-ray.
A rare pathology is Hoffa's disease – the transformation of the adipose tissue of the joint, which becomes fibrous and causes joint dysfunction.Against the background of this pathology, arthrosis often develops, which provokes pain in the knee joint.Reasons: hormonal imbalance, menopause in women.

Infectious joint pathologies
Against the background of infection, the knee joint hurts sharply, sharply, providing rest does not relieve the condition.Urogenital and intestinal infections can also cause complications in the musculoskeletal system, resulting in reactive arthritis.Bacteria (salmonella, chlamydia, gonococci and others) penetrate into the cavity of the bone joint with the bloodstream, settle in the tissue and cause inflammation.The tendons usually become inflamed as well, causing the knee to swell and feel hot to the touch.
Tuberculosis is a serious disease.Mycobacterium tuberculosis multiplies in bone tissue, causing bone fusion and necrosis of cartilage and soft tissue.Without urgent treatment, the knee joints hurt and collapse, and the process covers larger and larger areas.As a result, fistulas appear - cavities with pus, which can spill out and cause damage to the whole body.
An acute, urgent disease is osteomyelitis of bones.What should you do if your knees hurt and the process is accompanied by weakness, muscle pain and temperature up to 40 degrees?If the pain in the knee is dull, bursts and the tissues themselves are swollen, red and blue, you should urgently call an ambulance and go for emergency surgery.Otherwise, you could lose your leg or die.

Knee pain - causes of a degenerative nature
After the age of 50, a large number of people have knee pain.The prerequisites are aging of the body, wear and tear of the key apparatus and the development of the most common pathology - osteoarthritis (gonarthrosis).It leads to the thinning and destruction of cartilage with a change in the shape of the bone heads.More often, in the early stage of the pathology, knee pain on one side;after a few years, the lesion becomes bilateral.Stiffness in my legs bothers me in the morning, but it goes away quickly.Increased sensations are possible after physical work, intense sports or long walks.
In advanced stages, the joint tissue breaks down and osteophytes grow on the sides of the joint space.These are spines made of bone tissue, which in severe cases split and cause excruciating pain.There are a number of other degenerative pathologies, the symptoms of which will be similar to gonarthrosis:
- Osteochondropathy.It affects the articular surface of the bone, associated with injuries and sports.It can develop in teenagers for no apparent reason.
- Arthritis.It can be rheumatoid, psoriatic, gout and provokes chronic inflammation and joint destruction.
- Chondromatosis.The etiology is unclear.The disease causes the appearance of nodules in the synovial membranes, which limit the movement of the knee and cause pain.
Menopausal women often have knee pain due to osteoporosis – thinning of the bones, increasing their fragility.The disease is accompanied by leg cramps, pain in the spine and periodic fractures.

Other causes of knee pain
When your knees hurt, the etiology of the sensation may also be in damage to the peripheral nervous system.Thus, neuropathy of the sciatic nerve against the background of damage to the lumbar vertebrae leads to a variety of symptoms.A person's knees hurt, the hip area hurts, the joints of the limbs weaken and the sensitivity of the skin is impaired.Leg reflexes also change.
Sometimes the entire knee joint hurts due to vascular disorders.Only in adolescence you should not worry too much - due to the rapid growth of the body, the vessels do not have time to supply the bones with blood.With age, the condition of the joint normalizes - usually by the age of 18-20 the pain stops completely.
In old age, with atherosclerosis, the knees also often hurt, what to do in this case?Without normalizing fat metabolism, plaque will continue to deposit within the arteries.The vessels are blocked and stop the full supply of the lock.Arthrosis develops in it and the pain becomes chronic.Unpleasant sensations in the knee area can also be caused by varicose veins, thrombophlebitis and vascular thrombosis.
How to make a diagnosis?
People have knee pain quite often;how to treat the condition can only be determined after an examination.Both sharp and annoying pains in the knee are characteristic of many pathologies, some of them are very dangerous.For the diagnosis, you should contact a surgeon, orthopedist, neurologist, rheumatologist or traumatologist.He will conduct a study, find out the exact symptoms of the disease and identify accompanying signs.Also, at the initial appointment, the doctor will perform a series of tests and physical examinations to clarify the nature of the problem.
What should you do when your knees hurt, what instrumental methods will help identify the causes?It is usually described as:
- Ultrasound;
- MRI;
- CT;
- Radiography.
The choice of the correct technique should be left to the doctor.Thus, ultrasound does a good job of reflecting changes in the foot due to arthrosis and meniscus damage.X-rays perfectly show bone deformities and the presence of osteophytes.MRI and CT provide complete information;they are indispensable for complex diseases.In addition, the doctor will prescribe blood tests to rule out inflammation and rheumatism, and if necessary, a joint biopsy will be performed.For osteoporosis, densitometry is needed - it will show the patient's bone density.

Treatment of knee pain
If the pathology is traumatic in nature, the treatment is carried out by traumatologists, sometimes it is carried out in a hospital.Light bruising goes away on its own within a few days;to quickly resolve the hematoma, it is advisable to apply absorbable ointments to the knee.If pain occurs, ointments with non-steroidal anti-inflammatory components should be removed.
How to treat when the knee hurts due to the inflammatory lesion?In the acute phase of bursitis, synovitis, arthritis, the affected leg requires rest;Ice packs can be applied to it for 15 minutes during the first 3 days.Severe pain is relieved by injections of non-steroidal anti-inflammatory drugs and injections of anesthesia directly into the joint.To prevent chronic inflammation in the joint after pain relief, physiotherapy and exercise therapy are prescribed.

When a person has knee pain due to gonarthrosis, what should he do in this case?The main drugs for treatment are chondroprotectors and hyaluronic acid injections.These medications aim to restore the nutrition of the articular cartilage, as a result of which it stops deteriorating.Also, for knee rehabilitation, the following should be prescribed:
- Vascular medications;
- Physiotherapy;
- Gymnastics;
- Massage;
- Vitamin complexes.
Infectious diseases of the joints are an indication for the introduction of antibiotics into the joint cavities or taking drugs by mouth.In some cases, it is necessary to perform an operation to remove the tissue affected by the pus.Advanced forms of arthrosis with increased osteophytes are also treated with surgical intervention.Sometimes only replacing a joint with a prosthesis allows a person to maintain the ability to walk normally.
