Objective: In order to further explore the relevant factors that affect the postoperative effect of total arthroscopic treatment of shoulder instability, and the influence of different factors on the postoperative effect in a certain period of treatment.

Method: From 2013 to 2017, 57 patients underwent arthroscopic joint instability repair in the Affiliated Hospital of Chengde Medical College, all of whom received and completed at least a two-year follow-up. The basic data were collected and recorded, and logistic regression analysis was carried out on the related factors such as gender, injury side, injury mechanism, age of first dislocation, number of dislocations before operation, joint relaxation score (Beighton score), Bankart injury range (20%), Bankart repair + reimplissage operation (B + R), internal fixation form (single row / double row), time of starting active shoulder joint movement and so on.

Result: After two year's follow-up, the related factors affecting the postoperative outcome of the treatment of shoulder instability under the total arthroscope are: injury mechanism, number of dislocations before operation, joint relaxation score, Bankart injury range (20%), Bankart repair + replassage (B + R).

Conclusion: The main factors that influence the postoperative effect are the injury mechanism and the extent of Bankart injury. Slight external force can cause poor functional recovery of shoulder joint in patients with dislocation. Meanwhile, it has the most obvious influence on the subjective score and the excellent rate of shoulder joint function.
