To explore the indication and clinical effect of arthroscopic surgery for talus fracture. Methods A retrospective analysis was made on 32 patients with closed talus fracture treated in our hospital from January 2015 to June 2018. Among them, there were 23 males and 9 females, aged from 19 to 55 years, with an average age of 35.7 years; 15 traffic injuries, 11 falls, 2 sprains and 4 heavy-weight injuries．Among the 32 patients，19 cases with talus neck fractures, according to Hawkins talus neck fracture classification，6 cases with type I, 7 cases with type II and 3 type III.11 cases with talus fractures, according to Sneppen classification, 5cases with type II, 2 cases with type III and 1 type IV; There were 3 cases of simultaneous fracture of neck and talus. Results The operation time of 32 patients was 64-124 minutes, with an average of 95.7 minutes. All the 32 patients were followed up for 16 to 21 months, with an average of 18.64 months. Fracture healing time was 4-8 months, averaging 6.38 months. There were no complications such as wound infection, fracture nonunion and talus necrosis. 8 cases suffered from ankle pain after long walking. A0FAS score was 53-95, with an average of 73.65, and the excellent and good rate was 87.5% (27/32). Conclusion Arthroscopic treatment of talus fracture has the advantages of minimally invasive, direct reduction and internal fixation. Correct preoperative classification of talus fracture is conducive to ensuring the development of arthroscopic surgery.
