1-year postoperative follow-up is adequate for arthroscopic Bankart repair: a comparison between 1-year and 2-year postoperative patient-reported outcome scores.

Background: The optimal follow-up duration for arthroscopic Bankart repair remains unclear. This study hypothesized that a 1-year postoperative follow-up is adequate for patients undergoing this procedure. Methods: A retrospective cohort study was conducted from 2009 to 2020, including consecutive patients who underwent arthroscopic Bankart surgery at a university hospital. Seven different patient-reported outcome measures (PROMs) were recorded for all patients at 4 time points: preoperatively, 6 months, 1 year, and 2 years postoperatively. The time to achieve the minimally clinically important difference for the different PROMs was also recorded. Results: The study included 181 patients. Across all 7 PROMs, improvements exceeded the minimally clinically important difference, with maximal improvement observed by 1 year postoperatively. The complication rate was low (0.55%), and no redislocations occurred. Outcome scores showed no significant difference between 1-year and 2-year follow-ups. Conclusion: We conclude follow-up up to 1-year postarthroscopic Bankart repair is adequate for recreational athletes. These findings suggest potential optimization of health-care resources by reducing unnecessary clinic visits.
