There was a statistically significant association between postoperative usage and preoperative variables (mental health diagnosis, smokers, chronic pain, chronic regional pain syndrome, and use of non-narcotic medications). There was a statistically significant association between preoperative opioid use and 90-day readmission and postoperative complications. In this study, we found that patients taking opioids 1 to 3 months before arthroscopic knee surgery have increased risk of postoperative use. Additionally, chronic opioid use, chronic pain, or use of non-narcotic medications has the highest risk of postoperative opioid use. Finally, preoperative use was associated with an increased risk of 90-day readmission. Prognostic Level IV Evidence. Prognostic Level IV Evidence. To review the existing variables and their ability to predict recurrence of shoulder instability as it relates to the Instability Severity Index Score (ISIS), as well as evaluate any other pertinent imaging and patient history variables that may impact risk of recurrent anterior instability after arthroscopic Bankart repair. All consecutive patients with recurrent anterior shoulder instability and who had arthroscopic instability repair were identified. Exclusion criteria were prior surgery on the shoulder, posterior or multidirectional instability, instability caused by seizure disorder, or a rotator cuff tear. All ISIS variables were recorded (age <20 years, sport type and level, hyperlaxity, Hill-Sachs on anteroposterior external rotation radiograph, loss of glenoid contour on anteroposterior radiograph), as well as additional variables (1) number of instability events; (2) total time of instability; (3) glenoid bone loss (GBL) percent; and (4) Hill-Sachs measures (H/L/W/D/Volume). Postoperative outg, GBL greater than 14.5%, Hil
