Associated collateral ligament injury, incidence , importance and treatment

Tibial plateau fractures account for approximately %1 of all fractures. Tibial plateaufractures may occur together with meniscal and ligamentous injuries. The incidenceof associated collateral ligament injury was only %3 each for both MCL and lateralcollateral ligament (LCL). Schatzker type II fractures were associated with MCL tears,while Schatzker type IV fractures were most commonly associated with meniscalinjuries. Schatzker type IV, V, and VI patterns demonstrated a high incidence ofligament injury. PLC tears have association with medial plateau fractures andMCL tears have association with lateral plateau fractures. The management of acombination of fracture and multi ligament knee injury (MKI) in traumatic knee injuryremains controversial but in overall recommended the fracture should be treatedfirst, and ACL and PCL injuries may be treated after fracture healing. If continuedradiographic and clinical signs of instability are observed, a recommendation forstaged reconstruction of ligamentous injury should be considered after bony unionhas been achieved.
