Sore knee on the side from the outer side
The knee joint is a complex anatomical structure. Its components are located close to each other, and even the specialist did not immediately determine what exactly is the pain in the knee. Often patients complain of knee pain on the outside side. This uncertain symptom may talk about the damage to different elements of the knee. It is necessary to consider the main causes of pain that are localized on the external side of the knee.
The structure of the knee
To better understand knee pain it is good to have an idea about all the elements of the knee joint. It is useful to know the role of each part in the functioning of the joint. We list these agencies:
- 3 bones: femur, tibia and patella;
- hyaline cartilage covering the articulated bones of the knee;
- joint bag (capsule);
- the ligaments and tendons of the knee;
- the menisci;
- nerves and blood vessels.
The knee is formed by two tubular bones with rounded kneecap in the middle. The articular surfaces of the bones have Misaki – bone education. They have a femur in the form of exaltation, tibia Misaki flat and constitutes a chute, so the condylar groove, as on the rails, slides patella.
The end (epiphyses) of the bones of the joints are covered with cartilage tissue. The function of cartilage – reducing friction of bones during movement, the mitigation of impacts. A natural absorber of the knee in norm does not exceed 6 mm.
In the knee there are at least five synovial bags. Their size and exact number changes with age. The capsule consists of synovial membrane, which is attached to the bones between, under and on the side of the tendons. Synovial Bursa surrounding the joint cavity and protect it from injury. Inside the capsule contains synovial fluid. This joint and the secret lubricates the cartilage of the knee that prevents it from abrasion.
In the joint cavity is and ligaments of the joint. Connective tissue fibers fix the ends of the articulated bones of the knee. The outer ligaments reinforce the joint from the right side. The internal ligaments limit eversion knee back and forth.
Stabilize the joint during movement of the cartilage the formation of the meniscus. They are also located in and around the outer side of the joint. The sensitivity of the knee provides the popliteal nerve, which is located in the fossa of the knee. Then it is divided into two parts and surrounds the tibia and lateral tibia.
Traumas of the joint, in addition to the nerve can be damaged and blood vessels: popliteal artery and vein that nourish also the lower leg and the foot.
Problems with ligaments
Pain on the side on the outer side of the knee often caused by injuries. Such injuries can lead to tension, tears or complete ruptures of ligaments and menisci. Here are the main symptoms of ligament damage.
Sprains and tears of ligaments is diagnosed even in people active and not involved in sports. The fact that lack of exercise weakens the tone of the muscles and ligaments of the limb. With a slight increase in physical activity ligaments sedentary person fails.
The Golden rule of first aid in case of knee injuries – cold and quiet. It is important to immobilize the joint and apply to the injured side of the bandage with ice. Then as quickly as possible to examine the joint using ultrasound and x-ray to exclude torn ligaments and other damage to structures of the knee. Fully torn ligaments require surgical intervention.
Light sprains heal on their own. People can help the ligaments to recover faster, providing the joint at rest. Useful is wearing the orthosis.
Damage to the menisci
The meniscus can injure with a sharp extension of the leg, when the lateral impact. Cartilage formation can be broken, to tear, to break, to shift. The outer meniscus is more prone to injury, so the knee sick more often in the side. But the inner meniscus after an impact can also be crushed or completely severed. Symptoms of damage to the meniscus can be confused with a sprain and not to overlook the injury. But convincing evidence that the case is serious and requires immediate medical response will be the following characteristics:
- severe pain bottled up inside or to the outside of the side of the knee;
- the increase in temperature in the injured area;
- swelling and redness of the skin;
- the clicking in the joint during movement of the leg.
Indifferent to the injuries of the meniscus is unacceptable. Internal cartilage cannot regenerate in the absence of blood supply in this area. Therefore, different tears or compression, if untreated, lead to significant changes in the tissue of the meniscus. Education will be reborn in the cyst, exfoliate, they can cause cracks and erosion. The menisci will cease to perform its cushioning and protective function that will sooner or later lead to arthrosis of the joint.
For the diagnosis of meniscus injuries are x-ray, ultrasound and MRI of the knee. After the hardware of the examination the doctor prescribe treatment. The only possible method of treatment of meniscus tear is the removal of the injured part or the entire body – meniscectomy. More minor injuries such as tears, pinching meniscus, are treated conservatively. Apply steroid anti-inflammatory preparations, chondroprotectors and physiotherapy.
Specific treatment for pinched meniscus is a hardware traction – the traction on the joint apparatus.
The risk of inflammation
The inflammatory process in the synovial membranes of the knee is called «synovitis», and in the synovial bags – «bursitis». With this inflammation in the membranes and bags joint accumulates fluid (a special fluid). Early symptoms of synovitis and bursitis implicit and often patients complain of vague knee hurt in any way. A feature of bursitis is the occurrence of swelling on the side of the knee to 10 cm in diameter.
Both abnormalities may occur after trauma, especially open, with metabolic disorders, severe allergic reactions. Synovitis does not go unnoticed, untreated disease can lead to «edema» joint – gidrotartrata. Untreated bursitis can give impetus to the development of septic arthritis.
Accurate diagnosis the doctor may put after puncture of the joint and analysis of the exudate. Therapy of both diseases is to remove the causes of inflammation. Use anti-inflammatory drugs, when purulent form in the joint cavity administered antibiotics. Good effect gives physiotherapy treatments, for example, the method of shock wave therapy.
Inflammation in the knee joint as a whole is called «drives», that is, knee arthritis. Before its development is almost always diagnosed synovitis. When chase already exudate accumulates in the joint cavity. This pathology often has the infectious nature of the lesion: previous angina, tuberculosis, sexually transmitted diseases. On the second place among the causes of ganita are a knee injury. When the knee arthritis joint hurts completely, not only from the side, it is difficult to straighten. The disease is also accompanied by swelling and fever.
Arthritis treatment consists of antibiotic therapy, the inflammation and providing complete rest to the knee.
Other causes joint pain
Knee aches and crunches, especially side and when walking is a typical symptom of the destruction of the cartilage (osteoarthritis). Degeneration of the cartilage occurs slowly and imperceptibly, but she almost always preceded by a knee injury. With age, cartilage pads also irreversibly become thinner, and starts the deformation of the bones in the joint. Young people meet with gonarthrosis, if not watching your weight, do not treat the underlying disease, usually endocrine disruption.
Treatment of osteoarthritis symptomatic – pain relief. To fully restore the cartilage will fail, but slow down his destruction may with a reception chondroprotectors and introduction to joint injections with hyaluronic acid – a natural lubricant for the joints. Doctors do their best to delay the time of the transaction. But in severe forms of arthroscopy or arthroplasty is needed.
Not always my knee hurts because of its own pathologies. There are several reasons why pain may occur in the joint from the outside or from the inside.
|Flat feet.||Stop at such a low cushioning, very heavy foot. Constant tension in the muscles of the limbs leading to pain syndrome in the knees.|
|Osteochondrosis of the lumbar.||The nervous plexus in the lumbar is very sensitive, and a disease of the neural fibers can transmit pain and in the knee.|
|Cox.||Pain when inflammation of the hip joint often irradiiruet (gives) in the knee.|
|Varicose veins.||This disease can also be to blame for the fact that hurts the knee. The pain occurs because the damaged blood vessels in the limbs.|
It is obvious that the nature of pain in the knee joint from either side will accurately install specialist after a comprehensive diagnosis. And treatment of pain to be effective if therapy is initiated promptly and in the amount prescribed by your doctor.
