Abstract：Objective:To observe and compare the clinical effects of different arthroscopic suture methods in the treatment of discoid lateral meniscus injury. Method:84 patients with discoid lateral meniscus injury who underwent arthroscopic surgery in the hospital from June 2020 to June 2023 were selected as the study oubjects. They were randomly divided into the all-inside group and the inside-outside group,with 42 cases in each group. The patients of all inside group were treated with tatal internal suture. while the patients of inside-outside group were treated with inside-outside suture. Surgical conditions,postoperative signs,visual analogue scale (VAS) scores,Lysholm scores,and postoperative complications were compared between the two groups. Result:Intraoperative blood loss,surgical time and postoperative hospital stay of the all-inside group were significantly less than those of the inside-outside group (P<0.05). The positive rates of joint space tenderness,joint locking,and Mc Murray sign in the all-inside group were significantly lower than those in the inside-outside group (P<0.05). 1 month and 3 months after surgery,VAS scores of the two groups were significantly lower than those before surgery,and Lysholm scores were significantly higher than those before surgery. Above scores of the all-inside group were significantly better than those of the inside-outside group (P<0.05). No significant postoperative complications were observed in either group,but knee flexion and extension with discomfort and knee tightness in the appeared 3 months after surgery. The incidence was significantly higher than that in the all-inside group (P<0.05). Conclusion:Compared with inside-outside suture,applying all-inside suture in arthroscopic surgery for patients with discoid lateral meniscus injury can effectively shorten the surgical time,reduce intraoperative blood loss,alleviate joint pain,and avoid nerve and vascular damage,thus promoting knee function recovery and avoiding postoperative discomfort in knee flexion and extension as well as joint tightness.
