Abstract: Objective to explore the therapeutic effect of treatment of anterior cruciate ligament injury with tibial plateau plateau Schatzker type Ⅲ fracture with arthrascopic-asisted anterior cruciate ligament Anatomical single bundle reconstruction and arthrascopic-asisted tibial plateau plateau fracture reduction. Methods:twenty-six cases of anterior cruciate ligament ruptures with tibial plateau plateau Schatzker type Ⅲ fracture were chosed from June in 2017 to august in2018 in our hospital．All patients received arthrocopic-assisted anterior cruciate ligament Anatomical single bundle reconstruction and arthrocopic-assisted tibial plateau fracture reduction．All patients were followed up in time． Lysholm score were used in our reserch. Results :The patients werw all followed up for 10-18 months (Mean follow-up time 13.2 months)．ALL the fractures reached bone healing.At the final follow up,the final Lysholm score was (90.35 ± 3.25)points．The function of thejoint was excellent in 16 cases,good in 9cases．The excellent rate was 96．15％.Comclisions:The arthroscopic-assisted anterior cruciate ligament Anatomical single bundle reconstruction and arthroscopic-assisted tibal plateau fracture reduction teachnique has advantages in the diagnosis of anterior cruciate ligament injury with tibial plateau Schatzker type Ⅲ fracture, less bleeding, avoid staging operation, less cost, faster postoperative recovery, good curative effect
