Complex distal femur fractures can be difficult to stabilize, particularly when the metaphysis is comminuted or the fracture extends into the articular surface. This systematic review and limited meta-analysis evaluated the available evidence for dual-plate fixation, including comparisons with single-plate constructs. The review found that dual plating can provide satisfactory union and may accelerate healing in difficult fracture patterns. Across the included literature, however, the apparent benefit came with a trade-off: surgery generally took longer. The analysis did not show a clear advantage for dual plating in every functional or complication outcome, and the underlying evidence was limited by a small number of studies and mixed study designs. For clinical practice, the message is not that every distal femur fracture requires two plates. Rather, dual plating is a useful option when fracture morphology, poor bone quality, medial comminution or instability makes a single lateral construct less reliable. Patient selection and implant positioning remain critical, and the extra operative time and soft-tissue burden should be weighed against the need for a more stable construct.
