What exactly is an avulsion tear of the acl and what ways will they reconstruct my acl?

Avulsion fracture: Tibial spine fractures are characterized by fractures at the insertion site of the anterior cruciate ligament (acl) on the tibia and were first classified into 3 types. For displaced (type ii/iii) fractures, surgical treatment has included fixation with screws, sutures, or wires performed through either open or arthroscopic approaches. Optimal treatment methods remain controversial.
