Augmentation of full-thickness rotator cuff tears with a bioinductive collagen implant does not reduce retear rates - a propensity matched cohort study.
Article in BMC musculoskeletal disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeTo compare the clinical and radiographic outcomes after full-thickness RC repair with and without performing augmentation with a bioinductive collagen implant (BCI). MATERIALS AND
methodsConsecutive patients who underwent primary repair of a full-thickness supraspinatus tear between 05/2021 and 11/2023 were retrospectively identified. Patients at elevated risk for retear were defined by biological, radiographic, and intraoperative risk factors. Those who underwent repair with or without concomitant augmentation using a BCI and who had both clinical and radiographic follow-up at 1 year postoperatively were matched in a 1:1 ratio according to age, sex, body mass index, tear size, smoking status, diabetes, and American Society of Anesthesiologists physical status classification. Range of motion (ROM) as well as patient-reported outcome measures (Auto-Constant-Score (CS), American Shoulder and Elbow Surgeons (ASES) Score, Subjective Shoulder Value (SSV), and Visual Analog Scale (VAS) for pain) were recorded. Magnetic resonance imaging performed at 1 year postoperatively was analyzed and the presence of retear was recorded.
resultsIn total, 149 patients with a radiographic and clinical follow-up at 1 year postoperatively were identified. Of these, 23 patients with BCI augmentation were matched to 23 patients without placement of BCI (48% female, 59.2 ± 8.4 years at surgery). A retear occurred in 5 patients (21.7%) in the BCI augmentation group and in 3 patients (13.0%) in the control group (p = 0.72). No significant difference was reported regarding the CS (77 [71-83] vs. 76 [63-81], p = 0.5), ASES Score (92 [82-98] vs. 90 [84-95], p = 0.8), SSV (90 [80-100] vs. 90 [88-95], p = 0.9), VAS for pain (p = 0.74), or ROM between the groups.
conclusionIn this retrospective matched cohort of patients at elevated risk for retear, augmentation of full-thickness RC repair with a BCI was not associated with a reduced retear rate. Moreover, no significant differences regarding clinical and functional outcome were found between the two groups. LEVEL OF EVIDENCE: III - Retrospective case series with a matched control group.
