Consecutive patients undergoing arthroscopic frozen DTA were matched in a 1-to-1 format to patients undergoing open fresh DTA by age, body mass index, and number of previous shoulder operations. Patients were evaluated postoperatively in terms of the Western Ontario Shoulder Instability Index (WOSI) score, pain relief, and episodes of recurrent instability. All patients also underwent postoperative imaging evaluation with computed tomography (CT) in which graft incorporation and allograft angle were measured.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      A total of 100 patients (50 open fresh DTA, 50 arthroscopic frozen DTA) with a median \u00b1 IQR age of 32.0 \u00b1 6.7 and 27.9 \u00b1 15.9 years, respectively, were analyzed at minimum 2-year follow-up.
