Abstract：【Objective】To explore the clinical comparative study of the treatment of posterior cruciate ligament (PCL) inferior insertion avulsion fracture by arthroscopic suture fixation and nonoperation. 【Methods】The clinical data of 62 (Meyers Classification:Ⅱ、Ⅲ) patients with posterior crucial ligament inferior insertion avulsion fracture in our department from September 2013 to May 2018 were included in the retrospective study. They were divided into two groups randomly. The observation group included 32 patients (20 male cases and12 female cases) with PCL inferior insertion avulsion fracture treated with suture fixation by arthroscopy, while the control group contained 30 patients (17 male cases and 13 female cases). The healing time, tibial displacement (posterior drawer test: PDT), the Lysholm knee score, the hospital special surgery knee score (HSS) of both groups were compared between the two groups. 【Results】Both groups of patients were followed up for 6-24 months with average of (15.7±1.26) months. Results showed that 3 cases of non-healing by surgery in the control group nonunion who needed reoperation. The healing time of the observation group was significantly shorter than that of the control group (P<0.05), PDT grade, Lysholm score and HSS in the observation group were superior to the control group. 【Conclusion】The arthroscopic suture fixation of PCL inferior insertion avulsion fracture (Meyers Classification:Ⅱ、Ⅲ) is more effective than nonoperative treatment, which has higher stability and more improves joint motion function.
