Double Decker anterior cruciate ligament avulsion.

Distal anterior cruciate ligament avulsion from tibial side is an unusual injury. It can be either bony avulsion, which is more common, or rarely a soft tissue peeling of tibial spine with no bone injury. This case report represents a very infrequent injury of combined soft tissue peeling of distal anterior cruciate ligament along with bony avulsion of tibial spine in a 12-years-old boy after falling from his bike.
