Background: The arthroscope has long been recognized as a useful aid in the management of intraarticulartibial plateau fractures. The following study will clarify 50 cases of tibial plateau fracture types (I,II and III) present a rationale for arthroscopic reduction and internal fixation (ARIF), and review surgical techniques, results, and pitfalls. Aim of Study: This study evaluated the outcome of ar-throscopy-assisted reduction with internal fixation for treating tibial plateau fractures. Patients and Methods: Fifty patients with tibial plateau fractures treated by arthroscopy-assisted reduction with internal fixation (ARIF) were enrolled in this prospective study. According to the Schatzker classification, the fractures types were as follows: Type I, 17; type II, 14; type III, 15 & type V, 4. The mean age at operation was 28 years (range, 19 to 58 years). The mean follow-up period was 10 months (range, 6 to 12 months). Clinical and radiologic outcomes were scored by the Rasmussen system. Results: The mean postoperative Rasmussen clinical score was 26 (range, 19 to 30), and the mean radiologic score was 17 (range, 12 to 18). Good or excellent clinical and radiologic results were achieved in 96% of patients. Conclusions: (ARIF) for tibial plateau fractures is a safe, reproducible, and effective procedure that provides precise diagnosis and effective treatment in a 1-stage procedure.
