Why do we get dislocated?

Knee dislocation is a rare occurrence in the human skeletal system. Although knee dislocation is rare, it can unfortunately be very dangerous and complicated.

You should know that if you delay and neglect the treatment of knee dislocation, you will face very serious complications that sometimes become irreparable.

In the following, we will talk more about knee dislocation, its types and causes, and how to prevent knee dislocation.


Types of knee dislocations

  1. Congenital dislocations of the knee joint:

Congenital knee dislocation is a rare disorder. Usually these babies have a breech position and are born with a normal birth.(they are born with a foot.)

In this disorder, the child’s leg is bent upwards and bent in the opposite direction

Usually these babies also have other skeletal disorders, such as:

Congenital dislocation of the pelvic joint

Club Foot

This is how doctors describe congenital knee dislocation.

In patients, the quadriceps tendon in the front of the thigh is very short and stiff. In addition to this tendon, the ligaments around the knee are also stiff and short in length. It is said that sometimes there is no patella in these babies and even the knee bends to the left and right.


Examination of the baby and observation of an abnormal shape of the knee by a doctor determines the type of congenital dislocation of the baby’s knee.

There are three types of congenital knee dislocations that are listed below and we will only write their names:

Knee hyper extension

Knee subluxation

Total knee dislocation

Most children with congenital knee dislocation will recover with proper and timely treatment. Sometimes knee joint instability remains in the child but generally does not cause a problem for the person.

But the type of knee dislocation that we are going to talk about in this article is the following:

  1. Non-congenital knee dislocation:

This type of joint dislocation is rare but very dangerous due to the vascular proximity and important nerves of the knee and ligaments. You will read more about this type of knee dislocation below.


Why does a knee dislocation occur?

In order for the knee to become dislocated, a very large force must be applied to your knee joint.

The force must be strong enough to tear multiple and tight ligaments around your knee, which will lose their main restraints when the ligament ruptures. This is how the knee dislocates.


What are the symptoms of non-congenital knee dislocation?

Doctors say that after the knee joint is dislocated, the knee is usually returns to the same place where the accident took place.

Symptoms of knee dislocation in accidents and incidents include pain and swelling of the knee, which are generally two common manifestations of knee dislocation. In addition to pain and swelling, moving a knee can be very painful for a person with a dislocated knee.

A person with a dislocated knee has an unstable knee so he cannot put his weight on the affected knee.

If the knee has healed spontaneously, there will be a clear deformity of the joint.


Why is the correct and prompt treatment of non-congenital knee dislocation important?

Although knee dislocation is a rare joint dislocation in humans, it is very important.

The back of the knee is a very important passage for arteries and nerves. These arteries and nerves are very close to the bones on both sides of the knee joint when passing behind the knee, so it is possible that these nerves and arteries will be damaged in knee dislocations.

Because knee dislocation will be accompanied by displacement of the bones around the joint, displacement of these bones will most likely cause tension or pressure on the nerves and arteries behind the knee.


Possible side effects

Complications of knee dislocation include:

By moving the bones around the knee joint, pressure is applied to the arteries or the arteries may become stretched. However, injuries may be accompanied by damage and blockage of the arteries. Continued interruption of blood flow causes the death of these tissues and blackening of the foot.

The same injuries can occur to the nerves behind the knee. Following pressure or tension on the nerves around the knee, the foot becomes paralyzed and loses its sensation and movement. The severity of these injuries depends on the degree of nerve damage.

It is important that for any person who suspects a knee dislocation for any reason (following accidents or other incidents), the condition of the arteries and nerves around the knee, the sensation and movement of the lower knee tissues must be carefully examined at the same place of the accident or at most in the emergency unit.


How is a knee dislocation diagnosed?

We said that the treating physician should examine any patient suspected of having a knee dislocation for complete vascular and nerve damage.

Coldness of the injured toes and feet can be the first manifestations of vascular damage. Gradually, discoloration of the tissues will also occur.

The definitive diagnosis of knee dislocation will be a plain X-ray of the knee.

If there is a suspicion of vascular injury around the knee, duplex ultrasound of the area should be performed. In some cases, angiography is also required.


Treatment of non-congenital knee dislocation

For the reduction of a dislocated knee usually does not require much force and usually the reduction will be performed without the need for anesthesia or local analgesia.

However, sometimes in accidents, many tissues are trapped in the bones at the dislocation site, which makes closed reduction difficult. In these cases, open reduction is required with surgery, it means that the patient is anesthetized in the operating room and The doctor removes the affected tissues and performs reduction by making a suitable skin incision and with direct vision.

If the patient has an open dislocation, which means that the patient has a skin lesion that has been followed by a joint in contact with the external environment, or the vessels have been damaged during examinations and evaluations, the first step of surgery is necessary.

However, when the dislocated knee is repositioned, the injured knee joint should be kept immobile for some time.

Then physiotherapy should be started gradually so that the joint does not remain immobile for a long time and the normal range of motion of the knee joint is restored.

If a person has ligament damage around the knee, they may need surgery to repair the ligament damage around their knee after a few weeks to several months of regular physiotherapy.


What causes recurrent patellar dislocation of the knee?

Patellar dislocations of the knee are usually the result of abnormal structural problems.

For example, it may occur due to lack of growth and development of the inner thigh muscle or due to overgrowth of the outer thigh muscle.

The kneecap may be higher, or the outside of the femur may not grow well enough, or the knee may not be straight.

Your patella should normally roll in the trochlear cavity when the knee is bent and straightened. If patellar dislocation occurs, it means that the patella has been partially or completely removed from this cavity and there is a possibility of rupture and damage to the surrounding tissues.


Symptoms of patellar dislocation of the knee


Causes of patellar dislocation of the knee

Unlike rare knee dislocations, patellar dislocations or partial dislocations are common.

Sudden change of direction of the knee when the sole of your foot is on the ground, for example in sports. A knee injury when the sole of your foot is on the ground, for example in sports.


What is a partial dislocation of the kneecap and patella?

It is when the patella moves partially and temporarily from its place, which is the trochlear cavity, and is at the bottom and end of the femur (between the two protrusions at the end of the femur).


How do doctors diagnose patellar invisibility of the knee, partial dislocation and dislocation of the knee?

If the patella of the knee is dislocated, the doctor will notice the patella moving outward during the clinical examination, or the patella may deviate outward during the examination when the knee is bent and straightened.

An X-ray of the knee helps confirm the diagnosis. MRI is sometimes used to examine and evaluate injuries to ligaments and surrounding soft tissues.


The treating physician will choose the treatment method according to the patient’s condition:

With these equipment, the patella of the knee is kept firmly in its place and thus, not much pressure is applied on the knee during recovery.

Medical shoes and standard orthoses ensure that your thighs do not rotate inward too much

These braces, orthoses and medical shoes prevent deformity and bracing of the knee and changes in the wrist joint.

In people with unstable patella, this equipment will be prescribed by an orthopedist.

Surgery should be performed only in cases where there is a fracture or other accompanying injuries.

Doctors say that people who have experienced at least one patellar dislocation of the knee and have recurrence may need surgery in some cases.


What can we do to prevent knee dislocation?

In the following, we will introduce you to the ways to prevent knee dislocation.

Doctors believe that the best way to prevent knee dislocation is to stabilize the knee joint and the patella.

If the thigh muscles become strong, the knee and patella will be stable.

So doctors believe that the main way to prevent knee instability and patella is to do exercises that strengthen the thigh muscles.

The most important of these measures should be taken to strengthen the internal thigh muscles. There are a number of exercises that regular and correct exercise will strengthen the thigh muscles, increase the stability of the knee joint and therefore prevent knee dislocation.

If you want to prevent your knee from becoming unstable and dislocated, do the following with your doctor’s approval.

Exercises that strengthen the quadriceps muscle by strengthening it.

Such as squats or leg lifts

Standard exercise that strengthens the muscles inside the thigh.

Strengthen the back muscles or hamstring muscles that are done lying down.


The final word

In cases where the person has a patellar injury, a suitable brace or standard knee brace can prevent recurrence of the knee injury and dislocation to some extent.

It is recommended that athletes who do sports that have a high chance of interpersonal collisions and knee injuries use special protective knee braces.

We emphasize that in case of any knee injury, appropriate examination and treatment should be applied in the same initial phase. Chronic knee joint injuries, if left untreated, will generally cause more pain and instability of the knee over time.
