Knee joints are quite complex in functionality, but weak anatomically. They must constantly withstand heavy loads, so they are predisposed to injury and destruction.
Pain in the knee with flexion and extension is the most common reason for referring to traumatologists.
Actually, there are a lot of reasons why you can experience increased discomfort in the knee joint with flexion and extension.
This can be mechanical damage to the knee, a pathological change in the structure of the knee joint. In this case, the true cause of the pathology can be determined only through medical diagnosis.
Causes of knee pain
Knee pain can be caused by diseases such as:
- deforming arthrosis;traumatic or diathesis bursitis;
- Bechterew's disease;
- rheumatoid, gouty or septic arthritis;
- systemic lupus erythematosus;
- osteomyelitis;
- is lymphoblastic leukemia.
It is also a common symptom of bone metastases. This list of diseases is far from complete. Therefore, for the establishment of genuine reasons, a comprehensive medical examination is necessary.
- Pain, beginning at night, is more characteristic of gout.
- It is generally believed that the pain that intensifies during the day, accompanied by a snap in the joint, is a symptom of arthrosis.
- A pain in the knee during extension is most often indicative of bursitis.
Sometimes such phenomena develop as a result of trauma and are relatively easy to cure, with timely access to a specialist. However, more often they are a consequence of diseases that occur in a latent form, require careful diagnosis and adequate medical and surgical treatment.
Osgood-Schlatter disease
Osgood-Schlatter disease is an inflammation of the tendons, bones and cartilages in the lower leg. Most often from this inflammation suffer children involved in active sports. Specialists note that one knee is usually affected by an ailment. There is a sharp pain in the knee when bending - it's running, walking on the stairs and squats.
Arthritis and arthrosis of arthritis
This disease is associated with inflammation of the joints, or rather the articular tissue. This can happen because of heavy loads, or transferred infectious diseases.
Pain appears at night or in the morning, may occur after prolonged exposure to cold. Treatment is appointed by the doctor after the examination. It is aimed at relieving inflammation and swelling. Osteoarthritis destroys the joint. The knee can ache after a long time without movement.
Bursitis of the knee joint
The disease manifests itself in the form of inflammation of the bursa( intraarticular joint bag).
Periarticular tissues strongly swell, blush, feel warmer than others, when pressed they show soreness. When the joint moves, stiffness is noted. There may be a general increase in body temperature, muscle weakness.
For the diagnosis is enough for a visual examination of the doctor, you may need a puncture of the fluid inside the joint bag to determine the nature of the disease.
Tendonitis of the patellar ligament
Tendonitis is an acute inflammatory disease of collagen tendon fibers and their dystrophy. More often the disease develops in the place of attachment of the tendon to the bone or in the zone of the muscle junction in the tendon, there are cases of the widespread inflammation of the entire tendon.
The disease develops at different ages. More common tendonitis of the large joints of the extremities( upper and lower).
König disease
König disease is a type of osteochondropathy, which most often affects young men between the ages of fifteen and thirty( sometimes older and younger patients are found).
This condition is characterized by a limited area of necrosis of the region of the inner condyle of the thigh( articular cartilage + adherent bone tissue).With this disease, the bone-covering affected area of the cartilage begins to gradually peel off and eventually even completely separate from the bone.
Cyst Baker
Baker's cyst is a soft, tumor-like formation that is highly elastic. It develops in the popliteal fossa - on the back surface of the knee joint.
If you look at the photo of this disease, it becomes clear that with the bending of the foot, the formation decreases in size, and in some cases completely disappears.
Meniscus cyst
A meniscus cyst is a cavity filled with a liquid of a thick consistency of mucoid nature, and located on the edge or in the thickest of the meniscus.
It is formed, in most cases, due to a constant load on the knee, so in the risk group for this disease are athletes and people who are engaged in heavy physical labor. According to the statistics of the cyst the meniscus is diagnosed in the interval from 14 to 40 years, that is, in people of working age.
Osteoporosis
Osteoporosis( literally: porous bone) is a progressive decrease in bone density, resulting in a decrease in bone strength. This disease affects all the bones of the skeleton at the same time, which leads to the risk of fractures in the simplest life situations, under the most ordinary loads.
Treatment of pain when flexing and bending the knee
After a comprehensive diagnosis, a specialist trauma specialist diagnoses and prescribes a comprehensive knee pain treatment when flexing or flexing. First of all, non-steroidal anti-inflammatory drugs are used, folk remedies can be added to this. If the pain is unbearable, then most likely, they will prescribe the introduction of NSAIDs directly into the joint. This is achieved relief of painful manifestations for a long period and the patient remains able to work.
Also chondroprotectors( restorers of mechanical integrity and elasticity of cartilage) and artificial substitutes for synovial fluid( which plays the role of lubricant) are introduced into the joint cavity.
