Why knees crunch, what to do with crunching and pain with squats

Almost every person faces a crunch of joints in the knees that occurs regardless of age, sex, physical activity. Indeed, the knee joint is one of the most complex and mobile in the human body. Every day he takes on a significant load, participates in the processes of walking, running, squats, jumps, which determines the full motor activity. Thanks to the cartilaginous layers of bones and menisci involved in the formation of the joint, the knee performs a cushioning function, thereby preserving the health of the entire musculoskeletal system.

When the knee joint starts to crackle, some people consider this symptom a harmless manifestation and do not consult a doctor. Others prefer to immediately consult with a specialist in order to avoid negative consequences. Both do the right thing, but to make the right decision, one should know the causes of the crunch, which can be the result of physiological and pathological processes. Why crunches knees and how to distinguish the precursors of the disease from a healthy joint condition, will be covered in this article.

Physiological crunch

When moving in the knee joint, flexion and extension occur, which causes the bones to move relative to each other. For a quiet and smooth process, the articular parts of the bones are covered with a cartilaginous layer responsible for the durable work of the knee. In addition, there is a meniscus inside each joint, which is a cushioning cartilage and prevents the harmful impact of the shock axial wave during physical activity.

Stretching before going in for sports
A knee crunch after exercising shows excessive physical exertion on the lower limbs and requires optimization of the

training. However, during the movement, the joint bag that delimits the joint and secures the synovial fluid( lubricant) is stretched and increased in volume. This leads to the formation of bubbles in the liquid, which burst during climbing the stairs, when rising from the sitting position, squatting or sharp extension of the limb. Such a process is considered physiological and can occur at any age. For the physiological state is characterized by a sonorous strong crunch, which occurs with an intense load on the locomotor apparatus.

In childhood, a strong crunch in the knees is not uncommon. It should not cause concern to parents. The fact is that in the child of the preschool and school period the ligamentous apparatus and the muscular system responsible for the stability of the knee joint with movements of varying degrees of complexity are insufficiently developed. Given the high physical activity, children crunch their knees as a result of imperfection of the anatomical structure, with the thickness of the cartilage and the amount of synovial fluid in the normal state.

In a teenager, clicks in the knees are also caused by the physical development of the child at this age, but the reasons are completely different. In the pubertal period there is an intensive process of growth and endocrine adjustment of the body.

Functional processes in this respect are significantly lagging behind, which can cause weakness of ligaments, muscles, inadequate synthesis of synovial fluid. As you grow up, the "noise" in the joints gradually stops, the anatomical structures are strengthened, and the work of the musculoskeletal system is normalized. For children and young men there is no danger in the crunch of the knees, if it is not accompanied by pains, swelling of the soft tissues, general malaise.

Pathological crunch

It is quite a different matter when the knees crunch as a result of the development of the pathological process. This condition of knee joints requires comprehensive diagnosis and comprehensive treatment with the participation of a specialist - a rheumatologist, traumatologist, therapist. Clicks in the knees with diseases of the musculoskeletal system are constantly disturbed even with insignificant physical exertion and have a muffled character. In this case, there are usually severe pain, swelling of the joint, redness of the skin, an increase in local and general temperature, which significantly reduces the ability to move.

Causes of pathological joint crunches include:

  • trauma - mechanical damage to ligaments, articular surfaces of bones, synovial bags disrupting the biomechanics of the knee;
  • arthritis - inflammatory diseases of the joints, leading to edema of anatomical structures, disturbance of metabolic processes in the cartilage, accumulation in the cavity of inflammatory exudate;
  • arthrosis - the pathology of the joints associated with dystrophic processes in the cartilage, its thinning, proliferation of bone processes( osteophytes), a decrease in synovial fluid synthesis;
  • periarthritis - pathological processes in the periarticular tissues( ligaments, tendons, muscles), leading to instability of the knee.
Healthy and damaged joint
The structure of a healthy joint and pathologically altered as a result of inflammatory-dystrophic disorders of the anatomical structures of the

knee. The knees most often crunch when squats, especially deep, when the load on the knee joint exceeds eight times the body weight of a person. The complexity of the movements is that the maximum flexion gives a tremendous load to the ligamentous apparatus, the working group of muscles, which significantly brings the joint surfaces closer together. In conditions of pathology of the musculoskeletal system, sharp and deep squats should be avoided. With far-reaching arthritis and arthrosis, accompanied by the destruction of cartilage and meniscus, knees crunch when bent. Such a symptom on the background of pain and impaired motor activity should cause anxiety and require an immediate call to a doctor.

The disease of joints contributes to a number of unfavorable factors, which include:

  • infectious diseases;
  • autoimmune pathology;
  • endocrine disorders in the body;
  • is a sedentary lifestyle;
  • obesity, overweight;
  • untreated injuries of lower limbs;
  • excessive physical exertion as a result of hard work or playing sports;
  • irrational power supply;
  • congenital connective tissue features;Age-dependent involuntary changes;
  • menopause.

If the knees ache heavily and crunch, it is necessary to undergo a diagnostic examination for the purpose of complex therapy, which will prevent the development of irreversible changes in the knee joints.

Treatment and prevention of

To prevent pathological changes in the knees, prevention should be addressed, which includes normalizing nutrition, exercising and sports, timely therapy of concomitant diseases and injuries. The diet should include foods rich in vitamins and trace elements, especially such as tocopherol, calcium, magnesium. Fresh fruits and vegetables, as well as cooked by baking and steaming, preserve as much as possible all useful nutrients and promote their correct assimilation. Daily use of seafood and fatty fish, containing unsaturated omega-3 fatty acids. For people of mature and advanced age, cold, jellied, jelly are useful for regular nutrition, which include a large amount of chondroitin for the restoration of cartilaginous tissue.

Physical training and sports help to strengthen the muscular and ligament apparatus of the knees, improve blood circulation and normalize metabolic processes in the body. For people suffering from the pathology of knee joints with a crunch, walking, cycling, swimming in the pool and aqua aerobics, joint exercises, yoga are suitable. On the contrary, running, football, volleyball, intense workout in the gym can worsen the condition of the knees. To maintain the health of joints, it is sufficient to do daily morning exercises and short warm-ups once per hour for a long time in a static position.

Physiotherapy for the knee joint
Physiotherapy procedures are prescribed when the inflammatory process stops. They contribute to the rapid restoration of the motor functions of

. If pain and knee-jerking occur, you should contact a doctor who will tell you what to do to treat the pathological process. Usually, complex therapy is prescribed, depending on the cause of the disease.

  1. Non-steroidal anti-inflammatory drugs( NSAIDs) - movalis, diclofenac, nimesil, indomethacin.
  2. Analgesics - Tylenol, Solpadein, Mexavit, Reopyrin.
  3. Hormonal preparations - prednisone, dexamethasone.
  4. Chondroprotectors - rumalon, chondroxide, chondroitin.
  5. Local therapy - ointments, which may include all of the above groups of drugs.
  6. Trophic drugs - preparations of nicotinic acid, vitamins.
  7. Inhibitors of proteolytic enzymes - gordoks, trasilol.
  8. Antibiotics for the infectious process - ceftriaxone, cefazolin, erythromycin.

During the remission of the disease, physiotherapy( magnetotherapy, UHF, electrophoresis, ultrasound) and a complex of exercise therapy( LFK) are prescribed, strengthen the body's immune forces to prevent infections. In severe joint damage with contracture and destruction of cartilage, prosthetic surgery is performed.

As an additional method, folk remedies are used that increase the effectiveness of therapy and can be prescribed for the prevention of diseases of the knee joints.

The most popular ointments and compresses from the plant are golden mustaches( fragrant calligraphy).To prepare a medicinal ointment, fresh stems and leaves of the plant are taken, squeezed juice, mixed with a fat base( baby cream, petroleum jelly) in equal proportions. The agent is stored in the refrigerator, lubricate the affected joints thrice a day. To increase the effectiveness of plant ingredients, the ointment is used as a compress, which is applied for half an hour twice a day. The drug improves blood flow and metabolic processes at the site of pathology, normalizes the production of synovial fluid, reduces pain syndrome.

A crunch in the knees can be a sign of pathology and appear in physiological processes in the knee joints. To determine the true cause of clicks, you should consult a doctor for qualified help. It should be remembered that preventive measures are always better than treatment, and timely therapy will prevent the development of persistent violation of the function of the knees.
