Prospective study on effectiveness and safety of arthroscopic Bankart using a single anterior portal for patients with anterior shoulder instability

Comparison of anterior single- and standard two-portal techniques in arthroscopic Bankart repair

Objectives

This study aims to compare the outcomes of patients undergoing a single anterior portal or a standard two-portal arthroscopic procedure for Bankart repair.

Patients and methods

Between January 2015 and March 2018, a total of 71 consecutive patients (53 males and 18 females; mean age: 33.3±10.3 years; range, 17 to 56 years) who underwent arthroscopic Bankart repair with a minimum two-year follow-up period were included. The patients were divided into two groups according to the arthroscopic technique used: single anterior portal group (Group 1, n=32) and standard two-portal group (Group 2, n=39). Demographic and surgical characteristics of the patients were recorded. Pre- and postoperative clinical and functional outcomes were evaluated using the external rotation degree, as well as Visual Analog Scale (VAS), American Shoulder and Elbow Surgeons (ASES), University of California at Los Angeles (UCLA) Shoulder Rating Scale, Constant-Murley Score (CMS), Oxford Shoulder Instability Score (OSIS), and Rowe scores. The clinical and functional outcomes and revision rates were compared between the groups.

Results

The mean follow-up was 32.0±7.4 months in Group 1 and 38.0±13.4 months in Group 2 (p=0.222). Good-to-excellent postoperative functional and clinical outcomes were achieved in both groups at the final follow-up, compared to baseline (p<0.001 for all). No significant difference was observed in the postoperative outcomes including daily sports activity, VAS, ASES, UCLA Shoulder Rating Scale, CMS, OSIS, and Rowe scores, and external rotation restriction degrees between the groups (p=0.270, p=0.190, p=0.313, p=0.248, p=0.125, p=0.203, p=0.318, p=0.083, respectively). The operative time in Group 1 was significantly lower than that in Group 2 (60.3±8.3 vs. 71.4±7.2, respectively; p=0.001). Four patients (5.6%) experienced recurrent dislocation with no significant difference between the groups (p=0.622). No significant complications occurred in the peri- or postoperative period. Fifty-eight (81.7%) patients returned to their preoperative sports activity level. The mean time to return to sports was 7.2±1.7 months.

Conclusion

Good-to-excellent clinical and functional outcomes can be obtained after arthroscopic Bankart repair, regardless of the use of a single or two anterior working portals. However, the single-portal technique is associated with reduced the operative time, compared to two-portal technique.

How to Assess Shoulder Functionality: A Systematic Review of Existing Validated Outcome Measures

The objective of this review was to compile validated functional shoulder assessment tools and analyse the methodological quality of their validations. Secondarily, we aimed to provide a comparison of the tools, including parameter descriptions, indications/applications, languages and operating instructions, to choose the most suitable for future clinical and research approaches. A systematic review (PRISMA) was conducted using: PubMed, WoS Scopus, CINHAL, Dialnet and reference lists until 2020. The main criteria for inclusion were that papers were original studies of validated tools or validation studies. Pre-established tables showed tools, validations, items/components, etc. The QUADAS-2 and COSMIN-RB were used to assess the methodological quality of validations. Ultimately, 85 studies were selected, 32 tools and 111 validations. Risk of bias scored lower than applicability, and patient selection got the best scores (QUADAS-2). Internal consistency had the highest quality and PROMs development the lowest (COSMIN-RB). Responsiveness was the most analysed metric property. Modified UCLA and SST obtained the highest quality in shoulder instability surgery, and SPADI in pain. The most approached topic was activities of daily living (81%). We compiled 32 validated functional shoulder assessment tools, and conducted an analysis of the methodological quality of 111 validations associated with them. Modified UCLA and SST showed the highest methodological quality in instability surgery and SPADI in pain.
