Abstract
PurposeTo assess the modified one anteriorportal Bankart repair and compare it to the two-portal Bankart repair in terms of surgical time, functional scores, and recurrent dislocation. Material and MethodsPatients who underwent Bankart repair from 2014 to 2021 were identified and separated into two groups: a modified one anterior portal group and a two 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 of 2 years of follow-up. Patients were evaluated for their clinical results using the American Shoulder and Elbow Surgeons (ASES) score, the Western Ontario Shoulder Instability (WOSI) Index, and the Oxford Shoulder Instability Score (OSIS) pre- and post-operatively. The duration of surgery and recurrent instability were recorded. To prevent suture tangling in the modified one-portal group, two techniques were performed: "cannula in canulla” and "cannula in and out." ResultsA total of 42 subjects were included in this study, with 20 in the modified one portal group and 22 in the two-portal group. There were no statistically significant differences between the two groups in clinical scores obtained after two years of surgery (ASES score p =0.5, WOSI index p =0.22, and OSIS score p =0.32). The average surgical duration in the modified one-portal group (65.7±15.8) was significantly shorter than the average surgery duration in the two-portal group (81.1±27.2). (p=0.03). There was no statistically significant difference between the two groups for recurrent instability. (p=1.0) ConclusionBankart repair performed through a modified one anterior portal technique has a shorter surgical time and similar clinical outcomes as the two-portal technique.
