Gustilo-Anderson classification for open fractures	Schatzker classification of tibial plateau fractures
Type I: Clean wound less than 1 cm in size.	Type I: Split fracture of the lateral plateau.
Type II: Wound 1-10 cm in size with moderate soft tissue damage.	Type II: Split fracture of the medial plateau.
Type III: Wound greater than 10 cm in size with extensive soft tissue damage and contamination, further subdivided into IIIA, IIIB, and IIIC based on severity.	Type III: Depression fracture of the lateral plateau.
	Type IV: Depression fracture of the medial plateau.
	Type V: Bicondylar fracture with both medial and lateral plateau involvement.
	Type VI: Complex fracture pattern involving the entire tibial plateau.
