Outcomes of Arthroscopic Latarjet as a Revision Surgery After Failed Arthroscopic Bankart Repair
Bibliographic record
Abstract
Background: The role of arthroscopic Latarjet as a revision surgery after failed arthroscopic Bankart repair has yet to be established. Purpose: To compare clinical outcomes, recurrences, and complication rates of arthroscopic Latarjet as a revision procedure after failed arthroscopic Bankart repair versus arthroscopic Latarjet as a primary procedure. Design: Cohort study; Level of evidence, 3. Methods: This is a retrospective study of prospectively collected data of patients who were diagnosed with anterior shoulder instability and underwent arthroscopic Latarjet stabilization between 2009 and 2018. Patients were separated into 2 groups depending on whether Latarjet was performed after a previous instability surgery (revision) or as a primary surgery (primary). Rowe score, Western Ontario Shoulder Instability Index (WOSI), Constant-Murley Shoulder Outcome (CMSO) score, and Single Assessment Numeric Evaluation (SANE) were assessed pre- and postoperatively with a minimum 24 months of follow-up. In addition, pre- and postoperative levels of sports activity, dislocations, subluxations, and complications were assessed. Results: A total of 97 patients (n = 62 revision; n = 35 primary), with a mean age of 31.0 ± 8.8 and 29.4 ± 7.6 years old in the revision and primary Latajet group, respectively, met the inclusion criteria. The mean follow-up in the revision group was 32 months (24-53) and 35.5 months (27.7-42.2) in the primary Latarjet group. No significant differences between groups were observed in Rowe score (revision = 91.4, primary = 94.1; P = .223), CMSO score (revision = 90.7, primary = 94; P = .105), and SANE (revision = 85.8, primary = 87.3; P = .683) postoperatively. However, the postoperative difference in the WOSI score between the revision and primary Latarjet groups was nearly significant (510 ± 334 vs 403 ± 343, respectively; P = .05). Four (6.4%) postoperative dislocations were reported in the revision and 1 (2.8%) in the primary Latarjet group ( P = .14). Patients in the revision group had a lower return to the previous level of sports participation ( P = .008) and decreased external rotation with the arm by the side compared with the primary Latarjet group ( P = .000). Conclusion: Arthroscopic Latarjet as a revision surgery is a reasonable surgical option in failed Bankart repair cases. The decision to perform arthroscopic Latarjet stabilization as a revision surgery should not be influenced by the potential risk of future complications as it provides comparable clinical outcomes to the primary Latarjet procedure with a low postoperative recurrence rate. However, a decreased level of postoperative sports participation and external rotation with the arm by the side can be expected.

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.
