Quadriceps tendon avulsion

Quadriceps tendon avulsion is a traumatic injury where the quadriceps tendon detaches from the patella, often occurring during activities involving sudden knee extension or direct trauma. This condition is clinically significant as it can lead to knee instability, impaired mobility, and long-term functional deficits if not promptly diagnosed and treated. A key association is its occurrence in middle-aged individuals, particularly those with pre-existing tendon degeneration, increasing the risk of complications like re-rupture.
