What causes frequent knee dislocation?
Knee dislocations are often the result of a high-impact injury such as an automobile crash, severe fall, and sports injuries. A knee dislocation should not be confused with a subluxation, a partial dislocation in which the knee “gives out” due to a damaged ligament.
What happens if your knee keeps dislocating?

How common is a dislocated patella?
Patellar dislocations occur in about 6 per 100,000 people per year. They make up about 2\% of knee injuries. It is most common in those 10 to 17 years old.
How is patella dislocation treated?
Conservative management of these problems in season with appropriate rest, appropriate hip and thigh muscle strengthening, and perhaps the use of a patellar buttress brace is appropriate. Alternative treatments can include glucosamine, hyaluronic acid, and non-steroidal anti-inflammatory medications (NSAIDs).
How is a dislocated patella treated?
A dislocated kneecap will be quickly put back into position (referred to as “reduction”) by the consultant. This may need to be performed under local or general anaesthetic. Once the kneecap has been put back into place, you will need to rest the knee and use ice, compression and elevation to control swelling.
What causes the patella to dislocate?
A dislocated kneecap can be caused by: A blow to the knee, for example if the knee joint collides with another person or object with great force. A sudden change of direction while the leg is still planted firmly on the ground, such as during sports or dancing. Weak leg muscles which puts pressure on the knee joint.
What is recurrent patella dislocation?
Recurrent Patellar Dislocation occurs when the kneecap slides out of place. The patella is the bone more commonly known as the kneecap. It fits securely in a V-shaped groove in front of the knee and moves up and down when the leg is bent or straightened.
Is patellar dislocation painful?
A patella dislocation occurs when the knee cap pops sideways out of its vertical groove at the knee joint. It’s usually caused by force, from a collision, a fall or a bad step. A dislocated patella is painful and will prevent you from walking, but it’s easy to correct and sometimes corrects itself.
How painful is a patella dislocation?
Kneecap dislocation may cause sharp pain on the front of the knee when an individual tries to stand or put pressure on the knee joint. Over time, the pain in the kneecap will dull, but this is not necessarily indicative of healing. Localized tenderness. The kneecap will usually be painful to touch.
What causes patella dislocation?
Causes. Patellar dislocations can occur either in contact or non-contact situations. An athlete can dislocate his/her patella when the foot is planted and a rapid change of direction or twisting occurs. Usually a pre-existence ligamentous laxity is required to allow a dislocation to occur in this manner.
Do you need surgery for a dislocated knee?
Almost all knee dislocations require reconstruction surgery, because major injury to the artery occurs in many knee dislocations and because of the severe ligament injury. After appropriate treatment and surgery, however, results have been good.
What is a dislocated kneecap (patella)?
The kneecap (patella) is the bone that covers the knee joint. Abnormalities in the support structure of the knee and unusual forces can cause a dislocated kneecap. What is a dislocated kneecap? A dislocated kneecap is when the bone that covers the knee joint, the kneecap or patella, is moved out of place.
How do you relocate a dislocated patellar joint?
Following a patellar dislocation, the first step must be to relocate the kneecap into the trochlear groove. This often happens spontaneously as the individual extends the knee either while still on the field of play or in an emergency room or training room as the knee is extended for examination.
What makes patellar dislocation more likely in children?
A shallow or uneven groove in the femur can make dislocation more likely. Some children’s ligaments are looser, making their joints extremely flexible and more prone to patellar dislocation.
Can You dislocate your kneecap more than once?
Most people who dislocate their kneecap will not dislocate it again. But in some people it can keep happening. This often happens if the tissues that support the kneecap are weak or loose, such as in people with hypermobile joints, or because the groove in the bone beneath the kneecap is too shallow or uneven.
