Recurrent Instability After Arthroscopic Bankart Reconstruction: A Systematic Review of Surgical Technical Factors
Bibliographic record
Abstract
PURPOSE: Recurrent instability remains of concern after arthroscopic Bankart reconstruction. We evaluated various technical factors including anchor design, anchor material, number of anchors used, and interval closure on risk of recurrent instability after arthroscopic Bankart reconstruction. METHODS: A systematic review of MEDLINE and Cochrane databases was conducted, following PRISMA guidelines. Extracted data were recorded on a standardized form. Methodological index for non-randomized studies (MINORS) and Newcastle-Ottawa Scale (NOS) were used to assess study quality and risk bias. Because of study heterogeneity and low levels of evidence, meta-analysis was not possible. Pooled weighted means were calculated and individual study evaluation and comparisons (qualitative analysis) were performed for systematic review. RESULTS: Of 2097 studies identified, 26 met criteria for systematic review. Pooled weighted means revealed 11.4% versus 15% recurrent instability with 3 or more suture anchors versus fewer than 3 anchors, 10.1% versus 7.8% with absorbable versus nonabsorbable suture anchors, respectively, and 8.0% versus 9.4% with knotless versus standard anchors, respectively. Interval closure did not qualitatively decrease recurrent instability or decrease range of motion. CONCLUSIONS: Our systematic review reveals that despite individual study, and previous systematic reviews pointing to the contrary, the composite contemporary published literature would support no difference in the risk of recurrent instability after arthroscopic Bankart reconstruction with rotator interval closure, differing numbers of anchors used for the repair, use of knotless versus standard anchors, or use of bioabsorbable versus nonabsorbable anchors. We recommend surgeons focus on factors that have been shown to modify the risk factors after arthroscopic Bankart reconstruction, such as patient selection. LEVEL OF EVIDENCE: Level IV, systematic review of Level III and IV studies.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
