Arthroscopic Bankart Repair Using 1 Anterior Portal Has a Shorter Surgical Time and Comparable Clinical Results With the Standard 2-Portal Technique

Abstract

Purpose

To assess the modified 1 anterior portal Bankart repair and compare it to the 2-portal Bankart repair in terms of surgical time, functional scores, and recurrent dislocation.

Methods

Patients who underwent Bankart repair from 2014 to 2021 were identified and separated into 2 groups: a modified 1 anterior portal group and a 2 anterior portal group. The inclusion criteria were being >18 years old, having a recurrent anterior shoulder dislocation with a Bankart lesion, and having a minimum 2-year follow-up. Patients were evaluated for their clinical results using the American Shoulder and Elbow Surgeons score, the Western Ontario Shoulder Instability index, and the Oxford Shoulder Instability Score pre- and postoperatively. The duration of surgery and recurrent instability were recorded. To prevent suture tangling in the modified 1-portal group, 2 techniques were performed: “cannula in cannula” and “cannula in and out.”

Results

A total of 42 patients were included in this study, with 20 in the modified 1-portal group and 22 in the 2-portal group. There were no statistically significant differences between the 2 groups in clinical scores obtained after 2 years of surgery (American Shoulder and Elbow Surgeons score, P = .5; Western Ontario Shoulder Instability index, P = .22; and Oxford Shoulder Instability Score, P = .32). The average surgical duration in the modified 1-portal group (65.7 ± 15.8) was significantly shorter than the average surgery duration in the 2-portal group (81.1 ± 27.2) (P = .03). There was no statistically significant difference between the 2 groups for recurrent instability (P ≥ .999).

Conclusions

Bankart repair performed through a modified 1 anterior portal technique has a shorter surgical time and similar clinical outcomes as the 2-portal technique.

Level of Evidence
