Clinical Effect of Day-case Arthroscopic Surgery of Tibial Eminence Fracture using the Button Plates for Treatment in Adults

Abstract Background: The aim of this paper is to evaluate the early clinical efficacy and complications of arthroscopic treatment of tibial eminence fracture (TEF) with button plates. Methods: Retrospective analysis of patients with TEF fracture treated by arthroscopic surgery was performed. Clinical subjective evaluation included the International Knee Documentation Committee (IKDC) scores, Lysholm knee score, and visual analog scale (VAS). The knee joint scores were evaluated according to the Lysholm score. Clinical objective assessment included the Lachman test, anterior drawer test (ADT), IKDC, and the range of motion. The patient's quality of life was measured using a life summary table. Assessment of fracture healing and internal fixation was performed on lateral X-rays of the knee joint. The patients’ satisfaction was measured and evaluated at the last follow-up in accordance with Marsh criteria. RESULTS: There were 22 patients (22 knees) with a mean age of 33.64 ± 8.60 years. The mean follow-up was 28.36 ± 2.79 months. The difference in Lachman test and ADT before and after the operation was statistically significant. According to the IKDC classification, there were 11 cases with type A, 9 cases with type B, and 2 cases with type C. According to the intra-articular button position classification, the rate of ideal position was 100%. The satisfaction rate was 81.8%.CONCLUSIONS: Day surgery using double-button plates to treat TEF can achieve anatomical reduction, power and stability, and good clinical efficacy.
