Clinical and radiological outcomes after arthroscopic-assisted lower trapezius tendon transfer for isolated irreparable infraspinatus tear.
Article in Clinics in shoulder and elbow, 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
backgroundIsolated infraspinatus tears are rare and traditional arthroscopic repairs often result in unsatisfactory outcomes. This study evaluates the clinical and radiological outcomes of arthroscopically-assisted lower trapezius tendon (aLTT) transfer in patients with isolated irreparable infraspinatus tears.
methodsThis single-center retrospective study reviewed patients who underwent aLTT transfer for irreparable infraspinatus tears with no advanced glenohumeral arthritis. Clinical assessment included visual analog scale (VAS), Constant score, American Shoulder and Elbow Surgeons (ASES) score, and Single Assessment Numeric Evaluation (SANE). Shoulder range of motion was also evaluated. Radiographic evaluation included postoperative magnetic resonance imaging used to evaluate tendon integrity at final follow-up. Two patients were excluded due to loss to follow-up or incomplete data.
resultsSix patients were included, with a mean age of 60.7±4.1 years and a mean follow-up duration of 36.7±19.8 months (range, 24-75 months). At the final follow-up, VAS pain scores had improved from 6.0±1.4 to 1.7±0.8 (P<0.05). Functional scores had also improved: Constant score, from 51.5±5.6 to 72.0±6.4; ASES, from 60.5±4.5 to 82.0±6.3; and SANE, from 48.0±6.7 to 79.1±8.0 (P<0.05). Range of motion (ROM) improved in forward elevation (115°±12° to 170°±9°), abduction (95°±15° to 143°±16°), and external rotation at side (22°±11° to 51°±11°) (P<0.05). No progression of glenohumeral arthritis or tendon retears were seen on final follow-up.
conclusionsaLTT transfer significantly reduces pain, improves shoulder function, and restores ROM in patients with isolated irreparable infraspinatus tears. These findings suggest that aLTT transfer is an effective treatment option for this challenging condition. Level of evidence: IV.
