Arthroscopic Bankart repair using a single anterior working portal technique: a systematic review and meta-analysis

Purpose To evaluate the efficacy and outcomes of arthroscopic Bankart repair using a single anterior working portal and determine whether they are comparable to the standard two-portal technique. Methods A search following PRISMA guidelines was performed in July 2024 in the PubMed, Embase, Scopus, and Cochrane Library databases. Studies evaluating outcomes of patients undergoing arthroscopic Bankart repair using a single anterior portal technique were included. A meta-analysis comparing outcomes was performed using a random-effects model. A P-value < 0.05 was considered statistically significant. Results Seven studies in patients undergoing Bankart repair with a single anterior portal were included (311 patients, 84.6% male, mean age 27.8 years, mean follow-up 37.4 months). Five of seven studies compared outcomes of a single anterior portal versus the standard two-portal technique. The duration of surgery was significantly shorter in the single anterior portal group (P < 0.00001). The postoperative Oxford Instability Score (P = 0.84), Rowe score (P = 0.26), American Shoulder and Elbow Surgeons score (P = 0.73), Constant-Murley score (P = 0.92), and Visual Analog Scale Pain score (P = 0.07) were similar between both groups. The postoperative degree of shoulder abduction (P = 0.84) and external rotation (P = 0.64) were similar between both groups. The risk of redislocation (P = 0.98) was similar between both groups. Conclusion Patients undergoing arthroscopic Bankart repair with a single anterior portal had significantly lower operative times and comparable PROs, ROM, and risk of redislocation relative to patients undergoing repair with a standard two-portal technique.
