Causes of knee pain and effective treatment

Knee pain is one of the most common symptoms for which patients should consult orthopedists and other specialists.Many people completely ignore the appearance of unpleasant sensations, considering them due to age and almost natural.But there are many causes of knee pain, because it has a complex structure and is affected by a number of external and internal damaging factors.Some diseases are serious and require emergency treatment.

Who is more likely to get a knee injury?

The knee is formed by several bones connected by muscles, ligaments and tendons.There are also five synoviums - chambers surrounded by membranes designed to protect the joints.Between the joints there is articular cartilage - the meniscus, which helps the knee move freely.Disruption of even one area of the knee joint can lead to unpleasant symptoms.

Knee pain occurs especially often in people with flat feet.This is a foot disease that disrupts the limbs' ability to absorb shock.With age, the load on the joints increases, causing them to be destroyed and inflammation develops - a pain syndrome appears.Many types of foot and leg deformities have similar consequences.

There are several factors that influence knee pain to appear more often:

• Overweight;
• Passive lifestyle;
• High sports load;
• Diabetes;
• vascular disease;
• Age;
• Knee surgery and injuries;
• Work with increased loads on the legs.

Causes and treatments for knee pain vary widely, as does the severity of the sensation.If your knee hurts severely, the cause may be an injury or an advanced stage of arthritis, a severe inflammatory process.Sometimes symptoms become permanent, appearing even at rest, accompanied by swelling, redness and cracking.All these signs should alert a person and force him to see a doctor.

Pain from bruises in the knee

Among traumatic causes of joint dysfunction, bruises are the most common.Why does my knee hurt if symptoms are preceded by a small bruise?Even a minor injury is accompanied by bleeding into the soft tissues around the joint and swelling.As a result, the nerve roots become sore and pain appears.

In more severe cases, the pain in the knee increases when bending and straightening the leg, and the person stops moving due to a sharp pain in the joint.On palpation, you may notice swelling in your legs;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 give your leg a rest.

Usually the cause of knee pain after a trivial bruise is traumatic hemarthrosis.This is the phenomenon of blood flowing into the joint cavity, causing edema and swelling of the synovial membrane.As a result, the joint fills with blood and inflammation begins.Without proper treatment, injuries can lead to the development of osteoarthritis even at a young age.

Other types of knee injuries

If your legs hurt in the knees and injuries contribute to these sensations, the cause may lie in various damages to the components of the joints.Here are the main ones:

• Menisopathy.Indicates a collapsed or torn meniscus.Injuries are especially common among professional athletes, people participating in extreme sports, and family injuries.A person feels very painful in the knee, the nature of the feeling is piercing, like a dagger, the joint loses mobility for a while.
• Ligament damage.Ligament tears (sprains) occur when the leg is twisted, after jumping, or when the limb is stretched in an unnatural position.Sharp pain appears, legs swell, joint position changes, and becomes loose.
• Rupture of the cruciate ligament.Because these ligaments are located inside the joint, injuries often result in bleeding into the knee cavity.Just a puncture will help pump out the blood and make an accurate diagnosis.

Pain in the knee joint sometimes accompanies chronic patellar dislocation.If the acute injury is not treated, in some patients the dislocation will become chronic and cause frequent recurrences.In children, this pathology causes an X-shaped curvature of the leg and leads to severe impairment of its function.Sometimes the pathology affects the knees in both legs.

Inflammatory diseases of the knee

Often, standard treatments for knee pain are ineffective.In this case, it may not be the joint itself that is affected, but the surrounding soft tissues.Therefore, tendinitis or tendinitis can be caused by an increased load on the limb, previous leg injuries, allergies, reactions to medications, etc.With this disease, the knee joint often hurts during the day or evening;The pain subsides at night.In the acute stage, joint mobility is severely limited, the syndrome is persistent and cannot be treated with ointments and creams.A sharp sensation is also observed when palpating the lateral part of the knee.

If your knee hurts often, symptoms worsen after hypothermia, the cause may be synovitis - inflammation of the synovium.An inflammatory fluid appears inside the joint, causing a burning sensation and pain.The causes of the disease are very diverse:

• Autoimmune disease;
• Metabolic diseases;
• Past trauma;
• Arthritis.

Another “common” condition that causes knee pain is bursitis.It occurs when the synovium (joint capsule) becomes inflamed.In addition to pain, there is also redness, swelling and increased sensitivity in the kneecap area.If you do not clarify in time how to treat bursitis, it almost always becomes chronic.

Tumor in the knee joint area

Malignancies in this location are rare;Pain syndrome is characteristic of them only at a very late stage.Usually, pain in the knee joint is characteristic of benign forms:

• Baker's cyst.This tumor occurs below the knee, on its back.Outwardly, the skin above the cyst is normal, not inflamed;When bent, there may be no swelling at all.In the standing position, a clearly defined soft, elastic mass appears at the site of the cyst.It appears after unilateral knee injury or cartilage damage.Very often cysts are accompanied by chronic synovitis, arthritis, rheumatoid arthritis.Large cysts not only cause pain in the knees but also severely limit the mobility of the limbs.Because blood vessels and nerves are compressed, other symptoms include cold, pale skin, goosebumps, and numbness.
• Cartilage cyst.Appears in the outer or inner meniscus when there is a fluid-filled cavity inside the cartilage.In this case, the knee hurts after heavy loads or at the end of the day.Large cysts may be noticed on the lateral side of the joint, small cysts may only be visible by ultrasound or X-ray.

A rare disease is Hoffa's disease - a change in fatty tissue in the joints, becoming fibrous and causing joint dysfunction.Against this pathological background, arthritis often develops, causing pain in the knee joint.Cause: hormonal imbalance, menopause in women.

Joint infectious disease

In the setting of infection, there is severe pain in the knee joint, and rest does not relieve the condition.Even urinary tract and intestinal infections can cause complications in the musculoskeletal system, leading to reactive arthritis.Bacteria (salmonella, chlamydia, gonococci and others) enter the joint cavity through the bloodstream, deposit on tissues and cause inflammation.The tendons also often become inflamed, causing the knee to become swollen and hot to the touch.

Tuberculosis is a serious disease.Mycobacteria tuberculosis multiplies in bone tissue, causing bone dissolution and necrosis of cartilage and soft tissue.Without urgent treatment, the knee joints will become damaged and collapse, and this process will spread to larger and larger areas.As a result, fistulas appear - chambers filled with pus, which can overflow and damage the entire body.

An acute, urgent disease is osteomyelitis.What to do if your knee hurts and this process is accompanied by weakness, muscle pain and fever up to 40 degrees?If your knee hurts, aches, and the tissues are swollen, red and blue, you should urgently call an ambulance and go to emergency surgery.Otherwise, you could lose your leg or die.

Knee pain – cause of degeneration

After age 50, many people experience knee pain.Prerequisites are aging of the body, wear and tear of the joint apparatus and the development of the most common pathology - osteoarthritis (gonorrhea).It leads to thinning and destruction of cartilage with a change in the shape of the bone ends.Usually, in the early stages of the disease, the knee hurts on one side;after a few years, the lesions become bilateral.The stiffness in my legs bothers me in the morning but it goes away quickly.Increased sensation may occur after physical work, intense sports or long walks.

In severe stages, joint tissue collapses and bone spurs develop on both sides of the joint.These are spikes made from bone tissue, which in severe cases will break off and cause unbearable pain.There are a number of other degenerative diseases whose symptoms will be similar to gonorrhea:

• Osteocartilage disease.Affects the joint surfaces of bones, associated with injury and sports.It can develop in adolescents for no apparent reason.
• Arthritis.It can be rheumatism, psoriasis, gout and causes chronic inflammation and joint destruction.
• Chondromatosis.The cause is unclear.The disease causes the appearance of nodules on the synovial membrane, limiting knee movement and causing pain.

Women during menopause often experience knee pain due to osteoporosis - bones become thin and brittle.The disease is accompanied by leg cramps, pain in the spine, and periodic bone fractures.

Other causes of knee pain

When your knee hurts, the cause of the feeling may also be damage to the peripheral nervous system.Therefore, neuropathy of the sciatic nerve against the background of damage to the lumbar vertebrae leads to a number of symptoms.People experience knee pain, hip pain, weakened limb joints, and reduced skin sensitivity.Leg reflexes also change.

Sometimes the entire knee joint is painful due to vascular disorders.Only in adolescence you should not worry too much - due to the rapid growth of the body, blood vessels do not have time to supply blood to the bones.With age, the condition of the joints will normalize - usually by the age of 18-20, the pain will completely stop.

In old age, with atherosclerosis, the knees often ache. What should I do in this case?Without normalizing fat metabolism, plaque will continue to deposit inside the arteries.The vessels become clogged and stop providing adequate supply to the joint.Arthritis develops in it and the pain becomes chronic.Discomfort in the knee area can also be caused by varicose veins, thrombophlebitis and vascular thrombosis.

How to diagnose?

People experience knee pain quite often;How to treat this condition can only be determined after examination.Sharp and persistent pain in the knee is a characteristic of many diseases, some of which are very dangerous.For diagnosis, you should contact a surgeon, orthopedist, neurologist, rheumatologist, or traumatologist.He will conduct a survey, find out the exact symptoms of the disease and identify accompanying signs.In addition, at the first appointment, the doctor will conduct a series of tests and physical examinations to clarify the nature of the problem.

What to do when the knee hurts, what instrumental methods will help determine the cause?Usually prescribed:

• supersonic;
• MRI;
• CT;
• X-ray.

Choosing the correct technique should be left to the doctor.Therefore, ultrasound does a good job of reflecting changes in the leg caused by arthritis and meniscus damage.X-rays clearly show bone deformation and the presence of bone spurs.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, it is necessary to measure densitometry - it will indicate the patient's bone density.

Knee pain treatment

If the pathology is of a traumatic nature, then treatment is carried out by traumatologists, sometimes performed in a hospital.Mild bruises will disappear on their own within a few days;To quickly resolve the hematoma, it is recommended to apply an absorbent ointment to the knee.If pain occurs, ointment with non-steroidal anti-inflammatory ingredients should be applied.

How to treat knee pain due to inflammation?In the acute phase of bursitis, synovitis, arthritis, the affected leg needs rest;You can apply ice to the wound for 15 minutes for the first 3 days.Severe pain is relieved by injections of non-steroidal anti-inflammatory drugs and anesthetic injections directly into the joint.To prevent chronic inflammation in the joints after the pain subsides, physical therapy and exercise therapy are prescribed.

When a person has knee pain due to gonorrhea, what should be done in this case?The main drugs for treatment are chondroprotectors and hyaluronic acid injections.These drugs are aimed at restoring nutrition to joint cartilage, so that it no longer degenerates.In addition, for knee rehabilitation, the following must be prescribed:

• Vascular drugs;
• Physical therapy;
• Gymnastics;
• Massage;
• Vitamin complex.

Infectious diseases of the joints are an indication of the introduction of antibiotics into the joint cavity or the administration of drugs orally.In some cases, surgery is required to remove tissues affected by pus.Progressive forms of arthropathy with increased bone spurs are also treated with surgical intervention.Sometimes only joint replacement with a prosthetic joint can maintain the ability to walk normally.
