A dislocation – or distortion – is an injury in which the components of a joint move or separate. In case of knee dislocation, the femur and tibia separate and must return to their normal position.
In general, this only affects the bones. However, a doctor must determine if there is another injury to muscles, blood vessels or other adjacent body areas.
Common causes of knee dislocation
Currently, there are a few identified possible causes that lead to dislocation in any area of the body. Among them are:
- Trauma to the joint. This can vary slightly in location and intensity. The traumas can occur both during training or at work or while performing household chores.
- Bad circuit. If this is the case, a person have probably already developed an injury and are therefore more prone to them.
- Congenital changes. A person who has a number of congenital changes may have an increased risk of developing dislocations.
- Forced movement or poor support. In this case, a displacement is due to an involuntary, sudden movement.
In some clinical cases, a dislocation may occur spontaneously.

Symptoms of knee dislocation
In general, patients with this problem have a number of characteristic symptoms. Some of the most common signs of dislocation are:
- Intense pain or discomfort in the joint when a person tries to move it.
- Mild inflammation in the area of the dislocation. The injured person may also have bruises in the damaged area.
- There is a tingling sensation, tenderness and even numbness if there are changes in the nerves.
- A deformed joint usually occupies an unnatural position.
Dislocations are a common problem that can affect other joints.
Types of knee dislocation
If this is the first time a person has a dislocation in the knee, it may be due to a sudden injury that can become chronic. If, on the other hand, they have had such an injury in the past, it may be a recurring problem.
Some people develop dislocations in the body quite often. In this case, a possible cause of it is the presence of a disorder that affects the tissue that forms the joints, such as Marfan’s syndrome.
In general, there are several types of dislocations according to the movement of the tibia regarding the femur: Anterior, posterior, internal and external knee dislocation.
Treatment and rehabilitation
To begin with, doctors need to check the type of dislocation in an injured person. In all cases, the ultimate solution to the disorder is to move the knee components to their original position.
After performing this procedure, they should immobilize the knee with a splint. The immobilization time should also vary between two and three weeks, depending on the severity.
Similarly, in severe cases, surgery may be necessary. This is because it is the only way to put all dislocated bones back in place properly. Surgery can also repair all other damaged structures such as ligaments and meniscus if necessary.
Eventually, the doctor will release the joint after the rest period. After this, the person should begin a series of rehabilitation exercises as part of their therapy.
Overall, they may be able to regain most of their mobility.

As a general rule, this type of injury occurs during exercise. Therefore, patients can follow a number of simple guidelines to prevent this type of injury in the future.
Always wear appropriate footwear for the type of activity you are performing. In addition, if possible, avoid doing so on slippery surfaces where the risk of falling is higher. In any case, we recommend that you perform a warm-up before training to prepare your body for the exertion.
