Meyers–McKeever (± Zaricznyj) — Tibial Spine (ACL Avulsion)
Type I: Minimally displaced avulsion. Type II: Hinge of posterior fibers intact (anterior lift) — may reduce closed; fixation if interposed tissue. Type III: Completely displaced fragment — requires reduction and fixation. Type IV (Zaricznyj): Comminuted fragment — fixation with sutures/screws after debridement.
