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 their knee joints?

The knees are formed by several bones connected by muscles, ligaments, and tendons.There are also 5 synovial bursae - cavities surrounded by membranes 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 capabilities of the limbs.With age, increased loads on the joints cause their destruction and the development of inflammatory phenomena - pain syndrome appears.Various types of deformities of the foot and lower leg 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 greatly, as does the severity of the sensation.If your knee hurts badly, the cause may be an injury or an advanced stage of arthrosis, a severe inflammatory process.Sometimes the symptom becomes permanent, present even at rest, accompanied by swelling, redness of the skin, and crunching.All these signs should alert a person and force him to visit a doctor.

Pain due to bruises in 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 minor bruise?Even a mild injury is accompanied by hemorrhage into the soft periarticular tissues and their swelling.As a result, the nerve roots suffer and pain appears.

In more serious cases, 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 to your leg.

Often the cause of pain in the knee joint after a banal bruise is traumatic hemarthrosis.This is an outpouring 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 contributed to these sensations, the reasons may lie in various damage to the components of the joint.Here are the main ones:

  • Meniscopathy.Represents a flattening or tear of the meniscus.Injury is especially common in professional athletes, people involved in extreme sports, and also in household injuries.A person feels that the knee is sharply painful, the nature of the sensations is piercing, dagger-like, 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 extended 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, the injury often leads to bleeding into the knee cavity.Only a puncture will help pump out the blood and make an accurate diagnosis.

Aching pain in the knee joint sometimes accompanies chronic dislocations of the patella.Without treatment of 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 inflammation of the tendon, can be triggered by increased loads on the limb, past leg injuries, allergies, reactions to medications, 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 stage, joint mobility is severely limited, the syndrome is persistent and cannot be treated with ointments and creams.Sharp sensations are also observed when palpating 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 bursting and aching sensations.The causes of the pathology are varied:

  • Autoimmune diseases;
  • Metabolic diseases;
  • Past traumas;
  • Arthrosis.

Another “popular” disease that causes knee pain 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 location are rare; pain syndrome is characteristic of them only at the very late stage.More often, aching pain in the knee joint is characteristic of benign formations:

  • Baker's cyst.This tumor occurs under the knee, on its back surface.In appearance, the skin over the cyst is normal, not inflamed; when bent, there may be no swelling at all.In a standing position, a clearly defined, soft, elastic formation appears at the site of the cyst.It 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 compression of blood vessels and nerves, other symptoms include cold skin, pallor, goosebumps, and numbness.
  • Meniscus cyst.Appears in the external or internal meniscus when a cavity with fluid is localized inside the cartilage.In this case, the knees hurt after high loads or at the end of the day.Large cysts can be noticeable on the lateral part of the joint, small ones are visible only by ultrasound or x-ray.

A rare pathology is Hoffa's disease - transformation of the fatty tissue of the joint, which becomes fibrous and causes dysfunction of the joint.Against the background of this pathology, arthrosis often develops, which provokes pain in the knee joint.Reasons: hormonal imbalances, menopause in women.

Infectious joint pathologies

Against the background of infection, the knee joint hurts sharply, sharply, providing rest does not relieve the condition.Even urogenital and intestinal infections can cause complications on 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 on the tissues and cause inflammation.The tendons usually become inflamed too, causing the knee to become swollen and hot to the touch.

Tuberculosis is a serious disease.Mycobacterium tuberculosis multiplies in bone tissue, causing bone melting and necrosis of cartilage and soft tissue.Without emergency treatment, the knee joints hurt and collapse, and the process covers increasingly larger areas.As a result, fistulas appear - cavities with pus, which can pour out and cause damage to the entire body.

An acute, urgent disease is osteomyelitis of the bone.What to do if your knees hurt, and the process is accompanied by weakness, muscle aches, and fever up to 40 degrees?If the pain in the knee is boring, bursting, and the tissues themselves are swollen, red, and blue, you should urgently call an ambulance and go for emergency surgery.Otherwise, you may lose your leg or die.

Knee pain – causes of degenerative nature

After the age of 50, a huge number of people have knee pain.The prerequisites are the aging of the body, wear and tear of the joint apparatus and the development of the most common pathology - osteoarthritis (gonarthrosis).It leads to thinning and destruction of cartilage with a change in the shape of the heads of the bones.Most often, at the early stage of the pathology, the knee ache on one side; after a few years, the lesion becomes bilateral.Stiffness in my leg bothers me in the morning, but it goes away quickly.Increased sensations are possible after physical work, intense sports, or long walking.

At advanced stages, articular tissues collapse, and osteophytes grow to the sides of the joint space.These are spines made of bone tissue, which in severe cases break off and cause unbearable pain.There are a number of other degenerative pathologies, the symptoms of which will be similar to gonarthrosis:

  • Osteochondropathy.Affects the articular surface of the bone, associated with injury and sports.It can develop in teenagers for no apparent reason.
  • Arthritis.It can be rheumatoid, psoriatic, gouty, and provokes chronic inflammation and joint destruction.
  • Chondromatosis.The etiology is unclear.The disease causes the appearance of nodes on the synovial membranes, which limit the movement of the knee and cause pain.

Women in menopause 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 lie 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 number of symptoms.A person’s knees ache, the hip area ache, the joints of the limbs weaken, and skin sensitivity is impaired.Leg reflexes also change.

Sometimes the entire knee joint hurts due to vascular disorders.Only in adolescence should you 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 completely stops.

In old age, with atherosclerosis, knees also often hurt, what to do in this case?Without normalizing fat metabolism, plaque will continue to be deposited inside the arteries.The vessels become clogged and stop supplying the joint fully.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 nagging pain in the knee are characteristic of a lot of pathologies, some of them 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.Also, at the initial appointment, the doctor will conduct a series of tests and physical examinations to clarify the nature of the problem.

What to do when your knees hurt, what instrumental methods will help identify the causes?Usually prescribed:

  • Ultrasound;
  • MRI;
  • CT;
  • Radiography.

The choice of the exact technique should be left to the doctor.Thus, ultrasound does a good job of reflecting changes in the leg due to arthrosis and damage to the menisci.X-rays perfectly show bone deformations and the presence of osteophytes.MRI and CT provide complete information; they are indispensable for complex diseases.Additionally, 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.

Diagnosis of the causes of knee pain

Treatment of knee pain

If the pathology is traumatic in nature, treatment is carried out by traumatologists, sometimes it is carried out in a hospital.Light bruises go away on their 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 rubbed in.

How to treat when the knee hurts due to its inflammatory lesion?In the acute stage of bursitis, synovitis, arthritis, the affected leg requires rest; ice compresses can be applied to it for 15 minutes during the first 3 days.Severe pain is relieved with injections of non-steroidal anti-inflammatory drugs and injections of anesthetics directly into the joint.To prevent chronic inflammation in the joint after the pain subsides, physiotherapy and exercise therapy are prescribed.

knee massage for pain

When a person has pain in his knees due to gonarthrosis, what should he do in this case?The main drugs for treatment are chondroprotectors and injections of hyaluronic acid.These medications are intended to restore nutrition to the articular cartilage, as a result of which it stops deteriorating.Also, for knee rehabilitation, the following must 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 orally.In some cases, it is necessary to perform surgery to remove tissue affected by pus.Advanced forms of arthrosis with the proliferation of 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.
