What are the main types of patellar fractures?

The main types of patellar fractures include transverse, vertical, and stellate fractures.

Transverse fractures occur across the width of the patella, often as a result of direct trauma. Vertical fractures are characterized by a break that runs up and down, typically due to axial loading and can be less stable than transverse fractures. Stellate fractures involve multiple fragments and usually result from high-energy impacts, leading to a star-like appearance on imaging.

Understanding these fracture types is crucial in clinical practice because each type influences treatment decisions and expected recovery outcomes. Proper classification assists in determining whether surgical intervention is needed or if conservative management may be sufficient, especially given the critical role the patella plays in knee function and stability.
