Aims: Propose of this study is to evaluate the results of mini open surgical technique in treatment of tibial plateau fractures. Methods: Between September 1999 and September 2000, 10 patients (6 men, 4 women) with closed tibia plateau fractures were treated with arthroscopic and mini open surgical technique. The mean age was 48 (range 28–72 years). The mean follow-up was 26 months (range 20 months to 36 months). Schatzker classiþcation system was used for evaluation and classiþcation of the fracture patterns. Hence, three cases were type 1, four were type 2 and three cases were type 3. The arthroscopy was done in all the cases. No meniscus tears were found in all the patients. The plateau fracture has been reconstructed with elevation, through an antero-medial window in the proximal metaphysis of the tibia, with a particular carrot system. No autograft bone was adopted. We used a percutaneous þxation with AO cannulated screws (1–3 screws). Results: The results were evaluated with the HSS Knee Score System. There were no preoperative and postoperative complications. The results were 80% excellent, 20% good. The average of the Knee Score was 94 (range 78–100) and the average of the Functional Score was 96 (range 80–100). Conclusions: The arthroscopy and the mini open surgical technique create a complete anatomical reduction of articular fractured area with no graft.
