To evaluate the effectiveness and safety of the arthroscopic Bankart repair technique using a single anterior portal in patients with anterior shoulder instability.

Prospective study of 82 patients who underwent arthroscopic Bankart repair using a single anterior portal. Comparison with a historical series of 69 patients treated with two anterior portals. The patients were evaluated by the Rowe scale, and DASH (Disability of the Arm, Shoulder and Hand) and OIS (Oxford Instability Shoulder) questionnaires, range of motion and visual analogue scales for pain and patient satisfaction.

After a mean follow-up of 36 months, there were no significant differences between groups regarding clinical or functional scores, quality of life or patient satisfaction. Surgical time was significantly shorter in the 1-portal group. In group 1-portal there were 2 patients with neurapraxias and 2 re-dislocations, while in group 2-portals were 1 and 2, respectively. The worst functional results were associated with the presence of a type III SLAP lesion.

Both techniques were satisfactory regarding functional outcomes and complications, except for type III SLAP lesions. Using only one anterior portal, the surgical time was shorter, and the costs were lower when dispensing with a second cannula and a suture passing instrument.
