Why do knees ache when squatting?

Sick knees with knee bend

Sore knees when squatting

Knee pain while squatting is perhaps the most common complaint after weight training at a fitness club. The knee joint is very complex in structure, and therefore it is easy to damage - not only with the fall, but also with improperly performing exercises.

Why are knees ached while squatting?

The complaint of pain in the knee joint can be heard not only from a person of advanced age, but also from a young and healthy athlete. The reasons for such an annoying phenomenon can be very different:

  1. Wrong technique for doing squats, lunges and other exercises. When doing exercises, it is important to make sure that the knees look straight ahead( during the squat, the knees should be parallel to the foot and not go out for it) and not at an acute angle, because in this position too much load is placed on the joint, which contributes to the appearanceunpleasant sensations. If you feel pain in the knee joint when squatting, and not before or after it, chances are that your problem is exactly this.
  2. Sharp, sharp knee pain when squatting can indicate that you have sustained a serious injury - stretching or even rupturing the ligaments in the joint. In the event that the pain during squats is very strong and does not subside even after stopping the exercise, it is necessary to apply dry cold( ice wrapped in polyethylene and cloth) and contact a trauma doctor.
  3. If the pain in the knee is constant, and is strengthened when you squat or descend the stairs, chances are that you have Osgood-Schlatter disease. This disease often begins after a knee injury, but sometimes develops and for no apparent reason. Usually such a disease passes for 2-3 weeks and very rarely passes into a chronic form.
  4. If knees crunch while squatting, this can be an alarming symptom of developing arthrosis. In the first stages it is just a crunch and pain that pass after training, but already at this stage it is necessary to consult a doctor for qualified help.
  5. Excessive load - squats with heavy burdening, overweight, training at the limit of possibilities can also contribute to knee pains after squats. The load should be determined on the basis of its physical capabilities and never work at the limit, because as a result you will get no faster result, and serious health problems.
  6. For women, the actual cause of crunch in the knees when squatting is often the habit of walking on excessively high heels( above 5-6 cm).
  7. In addition, almost always a crunch or knee pain, if not a consequence of the injury, indicates a lack of vitamins and salt deposition, which requires a change in the type of nutrition to a more useful option( include more fruits and vegetables in the diet, and exclude sweet, salted, smoked, floury and fatty).

How to cope with pain in the knee?

Joints, especially the knee, require very careful treatment, why in any case it is recommended to consult a doctor. However, you can get rid of knee pain and folk methods, but they should be used as ancillary, and not as a substitute for the option offered by the doctor. The methods are as follows:

  • compresses from milk mixed with bran in a 1: 1 ratio. Such a compress should be fixed on a fixed knee for at least half an hour and repeated on a daily basis;
  • daily take warm baths for the knees. If desired, a decoction of herbs or essential oils can be added to the bath, and after 20-30 minutes, wipe dry thoroughly and spread the knee with any unrefined oil;
  • if you have a suspicion of arthrosis, be sure to perform an exercise "bicycle" or "scissors" 1-2 times a day;
  • Knee pain with squat
  • there is such an effective and simple exercise for strengthening the knees: put a pancake weighing 5-15 kg on the floor( start with the smallest weight, gradually increasing it), sit in front of him on the bench, and first move the inside of the toe( heel at the same time from the floordo not tear off), and then external( pancake should be returned to the place by hand).Repeat the exercise 20 times for each leg;
  • if problems with the knee became serious, it makes sense to undergo a course of physiotherapy;
  • ask your doctor, you should probably take special supplements;
  • with regular pain can try to use special orthopedic plasters on grasses.

The main thing is to control the load, and do not allow exercise "through pain", because the knee joint needs to be kept healthy and working until old age!


The most common causes of knee pain

Pain in the knee joints is a common, albeit non-specific, symptom that occurs both in adulthood and childhood. It is not always easy to correctly determine its origin, especially in the absence of any additional symptoms. The main causes and diseases in which the knees hurt are described in this article.

Complete list of the causes of pain in the knee joints

Pain in the knees is always associated with various kinds of changes in the components that make up the knee joint. The source of pain impulses can become structures that have nerve endings with their composition, or located near the reflexogenic and pain zones of the knee. These include:

  • bones and periosteum( tibial and femoral);
  • patella;
  • intraarticular hyaline cartilage;
  • intraarticular cartilaginous structures - menisci;
  • articular capsule;
  • synovium;
  • knee ligaments( cruciform and co-lateral);
  • periarticular handbags and knee joint twists;
  • muscles and tendons attached to the knee joint.

An exhaustive answer to the question of why knees ache is presented in the table.

It is important to remember! Any of the diseases in which the joints of the knees hurt, can occur in acute and chronic form. The stronger the pain syndrome, the more serious the problem. This can be either a testimony to an acute process, or signal the progression of a chronic one!

Pain in the knee
Deforming osteoarthritis is one of the most common causes of pain in the knee joints in the elderly

How to understand the cause of the onset of pain

The most common criteria for determining the cause of pain in the knees are as follows:

  • connection with certain movements;
  • the effect of loads on the occurrence of pain;
  • availability at night and at rest;
  • localization;
  • severity of pain syndrome.

Pains with

Some patients at the doctor's appointment focus on the fact that they have knees ached while squatting. This type of load is usually accompanied by pain, either almost at the end of the squat, or at the beginning of the ascent. The most common cause of this are chronic injuries of intra-articular structures( menisci and ligaments).In people of older age groups, such a complaint is mainly caused by deforming gonarthrosis. For this category of reasons, patients with knees ache during walking, especially fast, are suitable. Even more often, the result of long-term injuries and arthrosis are unpleasant sensations in the knee joints when walking on the stairs, since this kind of loads are characterized by the combined features of sit-ups with ordinary walking.

Roentgenography of the knee
Roentgenography of the knee joint is the main method for diagnosing the causes of pain in the knees

Pains during movements

Active and passive movements in the knee joints can provoke or intensify pain in this area. If pain does not arise at rest or during most movements, this excludes their inflammatory nature. In the case when the knees hurt with the maximum flexion of the limbs in the joints with the localization of pain in the popliteal region, it is worth thinking about the presence of effusion in the joint cavity. It can have the form of a bloody liquid after trauma( hemarthrosis), an excess of transparent intraarticular fluid against the background of exacerbation of arthrosis-arthritis. If only one knee is hurting when bending, it is more like post-traumatic consequences.

Pain in the knee joints during extension can be the result of deforming osteoarthritis, bursitis, meniscus lesions and patellar ligament. With bursitis such pains are not intensive, with the exception of a purulent form of the inflammatory process. Damage to the patellar ligament is accompanied by a difficulty of extension on the background of pain. Osteoarthritis and meniscus lesions, in addition to increasing pain in the knee during walking and in the process of extension, manifest a characteristic crunch. This joint can jam.

It's important to remember! A comprehensive assessment of the symptoms characteristic of knee lesions makes it as easy as possible to diagnose the causative disease!

Night pains

Few diseases are accompanied by pain in the knee joints at night. As a rule, this is a serious pathology that affects intraarticular cartilage. In the classical version, this manifests itself in 3-4 stages of gonarthrosis, as well as pronounced acute arthritis of any origin. Differential diagnostics between these causative diseases must be carried out on the basis of other symptoms( arthritis raises body temperature, and knees strongly swell).

Acute pain syndrome

Acute pain in the knee deserves great attention, as it signals serious problems. The sharpest pain occurs when the capsule and the synovial membrane of the knee joint are stretched. This is possible if there is a large amount of liquid in its cavity. Becoming the cause of its appearance is capable of an inflammatory process - arthritis. The onset of this disease can be associated with the transmitted infectious and systemic diseases of connective tissue. In the initial stage there is moderately severe pain. As the inflammation progresses, it becomes sharp, intense. If the process passes into the stage of suppuration, it manifests itself with a throbbing pain.

Pain localization

We recommend that you read: Pain in the knee Why do joints ache in the knees?

On the localization of pain in the knee joint can be tentatively judged on the causes of its occurrence. Very often, patients complain of local pain along the inside of the knee, a little lower and to the inside of the kneecap. Such sensations mainly indicate a different kind of damage to the inner meniscus with a medial ligamentous ligament. Similar pains outside and slightly below the patella on the outer surface of the knee indicate a rupture of the lateral meniscus attached to the same-named co-ligament. If they are felt directly inside the knee and are accompanied by instability of the joint, it is worth thinking about the damage to the cruciate ligaments.

Combination of pain with edema

For some diseases, patients complain about the fact that the knees are both swollen and sore. This combination of symptoms always indicates an acute process or marked exacerbation of the chronic. It can be arthritis of any origin, progression of gonarthrosis, acute post-traumatic period and long-term consequences of injuries of the lower limb. As a rule, the more swollen your knees, the more acute the pain and the more serious the disease. Local edema in the patella or any other area can speak of bursitis, tendonitis, Baker's cyst( when the edema is presented as a tumor in the popliteal region).

Compression for the knee joint
Treatment of pain in the knees should be differentiated and individualized.

. What are the pains in the knees in childhood

Quite often parents turn to orthopedists due to the child's complaints of pain in the knees. It is impossible to unequivocally estimate, from what they have appeared. In most cases, the pain syndrome is caused by the simultaneous action of regular factors. First of all, this is an active growth, accompanied by a physiological weakness of the osteoarticular apparatus. Secondly, the impact of high loads, which are subject to the bones of a child in everyday life. Because of this discrepancy, the bones, ligaments and other knee structures are overloaded, which can cause swelling and pain in the knee joints.

But transient physiological changes are far from the only cause of knee pain in children and adolescents. Thus there are a number of diseases, for example, such:

  • congenital and acquired osteodysplasia, arthropathy, chondropathy;
  • tumors of the bones of the lower extremities;
  • various arthritis( juvenile rheumatoid, rheumatic, jet and others);
  • trauma and post-traumatic complications( fractures, ligament ruptures, etc.).

It's important to remember! Pain in the knees of children should be given sufficient attention. A harmless symptom can be the first manifestation of a serious illness. Therefore, the child should be monitored dynamically and, with the slightest deterioration in the condition, consult specialists!

How to deal with pain in the knees

The presence of a persistent pain syndrome with localization in the knee joint is an indication for compulsory specialist consultation and a full examination. The main medical measures that you can use yourself, and specialized care are described in this article.

Pain in the knees is an ambiguous symptom, from which the diagnosis of both regular physiological and pathological conditions begins. You can try to go through the whole diagnostic path yourself, risking your health. But it is better to find a reliable doctor who will help to overcome the existing problem.


Many of us are familiar with the situation when the knee is hurting when squatting, no matter who you are a professional sportsman or ordinary pensioner. No one is immune from the appearance of such pains. It is important to determine why such discomfort arose. The reasons that caused the pain, in many ways, will depend on the treatment. Let's try to consider the most common reasons that knees ache when squatting.

Knee joint, structure

The knee joint is the most complex joint in the human skeleton. In addition to the fact that anatomically, it includes a large number of different ligaments, tendons and muscles that provide the necessary mobility, it connects the three largest human bones - the femoral bone and the tibia( small and large tibia).As a consequence, the knee joint experiences very heavy loads and, despite the fact that it has additional protection in the form of cartilaginous pads( meniscus) and patella, it can be easily damaged.

Causes of knee pain

The most common cause in a situation where knee pain occurs when squatting, young people become injured or have an incorrect distribution of physical activity in sports.

Inadequate physical exercise

If the pain occurs directly during squats and not after it or when you get up, perhaps the reason for the incorrect performance of the exercise. Being engaged in such loads it is important to make sure that the knees look exactly ahead, being parallel to the feet. While performing squats, especially with additional load, it is impossible to bend at the knee joint at an acute angle - in this case it gets too much load and there is a big risk of injuring the knee.

Damage due to injuries

Damage to the ligaments of the

Often, after a fall or stroke, stretching or even rupture of the ligaments of the knee joint occurs. As a rule, it is accompanied by acute pain, bruising and swelling of the tissues. If the associated ligaments, which hold together the femur and the bones of the shin, are located on the inner and outer surfaces of the leg, knee pains during squats and other physical exertions can remain even after the ligament treatment has been completed.

Tendonitis - tendon injury

Tendons are a dense fibrous tissue that connects muscles to bone sites. Such injuries are most often found in sportsmen professionally engaged in sports. However, the pain is not permanent, but manifests itself under physical exertion, that is, when running, jumping, climbing the stairs, or immediately after it. Usually, the pain manifests in the patella and the anterior part of the knee. Their manifestation depends on the degree of damage to the muscle and tendon. In severe injuries, when there is a complete rupture of the quadriceps muscle, a person can not walk. In such cases, surgical treatment is necessary.

Meniscus Damage

This is a partial or complete rupture of the cartilaginous tissue from which the meniscus consists. If this process is gradual, then, as a rule, it is not immediately noticed. It appears moderate pain and a small tumor. If a complete rupture of the meniscus occurs, the cartilage fibers often block the normal movement of the knee, causing severe pain. Surgical treatment in this case is inevitable, but if the destruction of the meniscus does not limit the mobility, then stop at the therapeutic effect.

Damage to the patella

As a rule, it happens the displacement of a small bone covering the front surface of the knee, to the outside of the limb. It is accompanied by severe pain and is often determined visually. With such trauma you can see that the bone has shifted and took a position perpendicular to the normal one. Unfortunately, after receiving such a trauma, repeated bias is possible.

Osgood-Schlatter disease

This pathology is usually affected by adolescents actively involved in sports. There are complaints of pain during exercise - squats, running, climbing the stairs. The pain can be of varying intensity from small to mild, and usually subside after the termination of the load. On the front surface of the joint there is swelling. As a rule, the disease proceeds in a chronic form and completely passes to the end of the period of bone growth.

Other pathologies of the knee joint

Do not forget that knee discomfort when squatting can become a symptom of a serious illness.

Diseases of the joints:

  • bursitis( inflammation of the joint bag);
  • arthrosis( cartilage damage).

In these cases, in addition to knee pain when squatting, as well as getting up, there will be signs of inflammation:

  • swelling;
  • changes the color of the skin over the joint, local temperature increase;
  • stiffness of movements;
  • the general reaction of the body is fever, weakness.

If pain in the knee joint is a manifestation of a disease caused by an infection or having other causes, treatment should not be postponed and consultation with a surgeon, orthopedist or rheumatologist.

Knee pain with squats - Powerlifting-ND

According to official statistics in Russia, more than 400 thousand ligament tears of the knee joint are annually recorded. In fact, this figure is much higher, because not all refer to a doctor. Of course, ligament damage is a serious trauma, but there are other causes of pain in the knees. Within the framework of this article, we will only consider knee pain with sit-ups. The knee is one of the most vulnerable places, because this joint connects the two longest bones of the body due to a very complex system of ligaments, muscles and cushioning system. The impact on the knee arises in any of our movements associated with the legs.

Quite often, athletes doing squats with a barbell complain of pain in the knee joint. The causes of this pain can be both physiological and purely technical. First of all, the cause of pain can be various diseases, for example, gonarthrosis. This disease occurs as a result of aging or premature wear of the cartilage of the knee joint. The causes of this disease can be malnutrition, viral infections and others. In this case, the treatment is best performed by a physician orthopedic trauma. Do not look for any folk remedies, or do not pay attention to the pain at all, as this disease progresses, and it will only get worse. Having summed up a little, it can be said that knee pain caused by any diseases must be treated by a doctor. Now let us consider other causes of pain, for which we can influence. As a rule, these are purely technical reasons. The most important thing when doing sit-ups is to observe the technique( here is an article on the squatting technique).From the point of view of physiology, squatting with the barbell on the shoulders is the most physiological and it is impossible to damage the knees with the right technique.

Consider the problems of the squatting technique, which can be hailed for knee injury:

1. Insufficient or total absence of warm-up. Unheated muscles and joints are not always able to cope with the load that you give in training, so they must first be brought to the state of "combat readiness". 2. Insufficient stretching and flexibility. "Clamping" the muscles and lack of flexibility in the joints can also lead to injury, so with insufficient flexibility, you should include stretching exercises in your program. 3. Non-compliance with the squatting technique - the knees fall inward or outward when lifting, which causes a significant load on the knee. In addition, when squatting the hips should look towards the socks, otherwise there are additional loads on the knee cartilage. To exclude such flaws of equipment is necessary at the initial stage of training, since squatting with considerable weight is likely to lead to trauma. 4. Squat best before the parallel. Some recommend squat below the parallel, but this squat repeatedly increases the load on your knees. 5. Do not increase the load sharply. For example, if you squat 150 by 5 times, then you should not try to sit 180 kg at the next lesson. Most likely your knees, and the rest of the muscles and joints simply will not be ready for this weight. 6. Many begin the workout with the press of the feet , but some athletes notice that if they move their feet with their feet after squats, their knees will stop hurting.

What to do if the knee of the

is already sick What if you started the approach and you have a knee pain? First, it's better to stop the exercise at once. Pain can not be ignored. If the pain does not pass after stopping squats, it is better to see a doctor. If the pain passes, then try to squat with much less weight and try to determine the condition of the knee. There is one more thing - squatting in bandages. The absolute majority is confident that bandages protect the knee from injuries while squatting, however, this stick also has two ends. On the one hand, bandages do stabilize the knee when squatting, and, on the other hand, bandages give false confidence in the protection and athletes begin to increase weight on the bar, although the muscles and joints are not yet ready for such a jump. Therefore, when knee pain occurs, it is worth crouching with light weight, without using bandages( unless, of course, you used them before). All those who practice power squats are advised to drink food supplements containing glucosamine and chondroitin.
