This retrospective cohort study evaluated the Less Invasive Stabilization System (LISS) for mechanically unstable distal femur fractures (AO/OTA types A2, A3, C2, and C3), asking whether locked plating with indirect reduction techniques could overcome the historical problems of varus collapse, malunion, and nonunion in these high-energy injuries.
When treating high-energy distal femur fractures (AO/OTA A2, A3, C2, C3), LISS locked plating with indirect reduction reliably achieves union while avoiding the varus collapse and fixation failure that historically plagued these injuries — even in open fracture patterns.
