Abstract: Background: Arthroscopic repair treatment of anterior shoulder dislocation can fail. We hypothesized that patients who are at higher risk for reoccurrence of dislocation after following repair treatment could be recognized preoperatively on the basis of their clinical history. The purpose of the present study was to identify the risk factors for recurrence in a community-based population of patients with traumatic unidirectional instability that was treated with a single arthroscopic technique. Method and results: Consecutive unselected patients (182; 186 shoulders) with recurrent instability (redislocation or subluxation) were selected. at Fatima Memorial Hospital Lahore during 2018–2019 arthroscopic sutureanchor repair treatment was used to operate initial traumatic anteroinferior shoulder dislocation .from case records all the data were retrospectively such as demographic data and details of operation, and glenoid and preoperative radiographs were used to assess the glenoid and Hill–Sachs lesions. The primary outcome measure was recurrence of instability (redislocation or subluxation). By using Oxford instability scores and subjective shoulder values (SSVs), using postal questionnaires Functional results were assessed. One hundred and seventy-four shoulders were assessed after a median of 51 (range 24–95) months’ follow-up. 19% of recurrences rate of instability was observed (redislocation 9% and subluxation 10%). further surgery was needed by only eight patients and needed by on. The mean Oxford instability score was 21 and the mean SSV 84%. 44% recurrent rate was found among patients aged 20 or less and among patients over 20, 12% rate. Logistic regression analysis stated that age ≤20 (OR 8.8), Hill–Sachs lesion (OR 3.3), glenoid erosion (OR 2.7) and length of follow-up (OR 1.5) were the most important risk factors for recurrence. Conclusions: Our study identified factors that are independently associated with a higher risk of recurrence following arthroscopic .Patients who are more likely to have a redislocation following arthroscopic repair of an anterior shoulder dislocation can be identified preoperatively on the basis of sex, age, and the time from the first dislocation to surgery.
