Arthroscopic Rotator Cuff Repair with and without Acromioplasty in the Treatment of Full-Thickness Rotator Cuff Tears
Bibliographic record
Abstract
BACKGROUND: The primary objective of this prospective randomized controlled trial was to compare functional and quality-of-life indices and rates of revision surgery in arthroscopic rotator cuff repair with and without acromioplasty. METHODS: Eighty-six patients consented and were randomly assigned intraoperatively to one of two study groups, and sixty-eight of them completed the study. The primary outcome was the Western Ontario Rotator Cuff (WORC) index. Secondary outcome measures included the American Shoulder and Elbow Surgeons (ASES) shoulder assessment form and a count of revisions required in each group. Outcome measures were completed preoperatively and at three, six, twelve, eighteen, and twenty-four months after surgery. RESULTS: WORC and ASES scores improved significantly in each group over time (p < 0.001). There were no differences in WORC or ASES scores between the groups that had arthroscopic cuff repair with or without acromioplasty at any time point. There were no differences in scores on the basis of acromion type, nor were any interaction effects identified between group and acromion type. Four participants (9%) in the group that had arthroscopic cuff repair alone, one with a Type-2 and three with a Type-3 acromion, required additional surgery by the twenty-four-month time point. The number of patients who required additional surgery was greater (p = 0.05) in the group that had arthroscopic cuff repair alone than in the group that had arthroscopic cuff repair and acromioplasty. CONCLUSIONS: Our findings are consistent with previous research reports in which there was no difference in functional and quality-of-life indices for patients who had rotator cuff repair with or without acromioplasty. The higher reoperation rate was found in the group without acromioplasty. Further study that includes follow-up imaging and patient-reported outcomes over a greater follow-up period is needed.

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.
