Does tear size influence factors associated with early retear, satisfaction, and functional outcomes after arthroscopic rotator cuff repair?
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundDeterminants of structural retear, patient satisfaction, and functional outcomes after arthroscopic rotator cuff repair may vary by tear size and influence surgical decision-making. PURPOSE: To determine whether tear size influences factors associated with early structural retear, postoperative satisfaction, and functional outcomes after arthroscopic rotator cuff repair. STUDY
designCohort study; Level of evidence, 3.
methodsA total of 1,166 primary arthroscopic rotator cuff repairs were categorized by mediolateral tear size as small (≤10 mm), medium (11-29 mm), or large (30-50 mm). At 6 months, patients underwent standardized ultrasound evaluation for structural retear and completed a 5-point satisfaction scale. Shoulder strength and range of motion were measured. Multivariable regression analyses were performed separately for each tear size group.
resultsAssociations with structural retear differed by tear size. In small tears, older age, longer operative time, greater anteroposterior tear dimension and preoperative stiffness were associated with increased retear risk, while anchors number showed no association. In medium tears, older age, larger anteroposterior tear dimension, and greater preoperative supraspinatus strength were associated with retear risk, whereas greater number of anchors reduced this risk. In large tears, retear was associated with factors including age, sex, range of motion, and pain at rest, with no association with anchors number. Satisfaction also varied by tear size: greater anchors number was associated with higher satisfaction in small tears, whereas in medium and large tears satisfaction was related to shoulder-related factors. The number of anchors was not consistently associated with postoperative strength or range of motion.
conclusionFactors associated with re-tear, satisfaction and functional outcomes vary by tear size. Greater number of anchors reduced the odds of retear only in medium tears and showed minimal association with functional outcomes, supporting tear size-specific counselling and surgical planning.
