Understanding Knee Hyperextension
Definition of Hyperextension
Hyperextension of the knee occurs when the knee joint bends beyond its normal range of motion, typically in the direction opposite to how it naturally bends. This condition can be acute or chronic. Acute hyperextension happens as a sudden injury, while chronic hyperextension develops over time. It is essential to recognize this condition to determine appropriate treatment options [1].
Causes and Types
Naturally hyperextended knees can result from various activities, particularly during sports or physical tasks. Common causes include:
- Traumatic Injuries: Sudden incidents such as falls or awkward landings can cause hyperextension.
- High-Impact Sports: Sports like gymnastics, basketball, and soccer, which involve jumping, tackling, or quick direction changes, put athletes at higher risk for knee hyperextension [2].
