Introduction: In this study, we aimed to ascertain the feasibility and reliability of the plate-on-plate technique for peri-implant fractures of the distal femoral locking plate when the distal femoral fracture is still unhealed. Materials and methods: From January 2007 to December 2016, we enrolled 11 patients who received treatment at our institution. All patients underwent at least 1 year of follow-up. Their medical records, imaging studies, visual analogue scores, walking ability, complications, and functional outcomes at 1 year postoperative based on the Short Form (36) Health Survey (SF-36) scores were retrospectively evaluated. Results: The average follow-up duration was 20.5 (range 15–30) months. All fractures united with satisfactory alignment, and the average time for union was 27.5 (range 16–40) weeks. The average SF-36 scores at 1 year postoperative was 79.2 (range 72–90). Regarding ambulatory status, all patients could perform unrestricted outdoor ambulation. Conclusion: In our case series, the plate-on-plate technique achieved a good bone union rate and functional outcomes with low complication rates and thus may be a good alternative for managing this difficult type of fracture.
