What is Hyper-Extended Knee?
A hyperextended knee is a condition in which the knee joint is bent backward beyond its normal range of motion. It can occur when the knee is forced into a position that it is not designed to withstand. This type of knee injury is most common among athletes and can cause pain, swelling, and instability in the knee joint.
Common Causes of a Hyperextended Knee
A hyperextended knee can occur in any activity or sports that involve sudden stops and turns or involve contact with another person. It is most common in sports such as basketball, soccer, and football. In basketball, it can occur from landing on the foot of another player or when the knee is bent backward during a jump or pivot. In soccer, it can occur when the knee is bent backward while making a tackle or during a sudden change of direction.

The most common symptom of a hyperextended knee is pain in the knee joint. Other symptoms may include:
- Swelling: The knee may be swollen and tender to the touch.

- Locking: The knee may feel like it is locked in position.
- Bruising: There may be bruises around the knee.
Diagnosis of a Hyperextended Knee
A doctor will typically diagnose a hyperextended knee by performing a physical examination. During the examination, the doctor may ask questions about the injury and may order x-rays or an MRI to confirm the diagnosis.
Treatments for a Hyperextended Knee
The primary goal of treatment for a hyperextended knee is to reduce pain and swelling and to restore normal knee function. Treatment options may include:
