Arthroscopic Upper Third Subscapularis Tendon Repair Using H-Loop Technique: A Case Series.
Article in Orthopaedic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveArthroscopic repair of upper one-third subscapularis tendon tears remains challenging due to suture management difficulties and repair quality limitations. We proposed a simpler knotless technique-the H-Loop technique. This study evaluates its early clinical and imaging outcomes.
methodThis is a case series of 38 patients (9 males and 29 females), who underwent arthroscopic H-Loop technique repair for upper one-third subscapularis tendon tears between January 2021 and August 2023. Postoperative assessments include the American Shoulder and Elbow Surgeons (ASES) score, the University of California, Los Angeles (UCLA) shoulder score, the Constant-Murley score, the visual analog scale (VAS), range of motion (ROM) (internal and external rotation), and internal rotation strength. In addition, MRI (30 patients) evaluated fatty infiltration, re-tears, and subscapularis integrity, comparing tendon dimensions and signal-to-signal ratios with a control group of patients with normal subscapularis tendons.
resultPreoperative symptom duration ranged from 3 to 36 months, with an average of 9 months. Follow-up ranged from 12 to 14 months, with an average duration of 12.6 months. No complications were observed in any patient. Postoperative ASES scores increased significantly compared to preoperative scores (55.63 ± 15.85 vs. 88.92 ± 8.24), as did UCLA scores (21.82 ± 4.44 vs. 29.74 ± 3.55) and Constant-Murley scores (69.76 ± 15.30 vs. 86.34 ± 14.48). VAS scores decreased significantly (5.16 ± 1.84 vs. 0.89 ± 0.76). Postoperative ROM showed significant improvement in internal rotation (7.79 ± 2.07 vs. 8.45 ± 1.33) and external rotation (57.63° ± 15.84° vs. 66.58° ± 9.08°) (p < 0.05). Internal rotation strength ratios increased markedly (78.00% ± 15.86% vs. 91.97% ± 6.62%). MRI indicated no re-tears or fatty infiltration in the 30 patients, and compared to the control group, there were no statistically significant differences in the vertical diameter of the subscapularis muscle (62.89 mm ± 9.30 mm vs. 59.41 mm ± 7.55 mm; p = 0.153), transverse diameter of the upper subscapularis muscle (17.82 mm ± 3.79 mm vs. 19.43 mm ± 4.76 mm; p = 0.395), transverse diameter of the lower subscapularis muscle (24.09 mm ± 5.84 mm vs. 25.23 mm ± 5.41 mm; p = 0.870), cross-sectional area of the subscapularis muscle (1338.54 mm
conclusionThe arthroscopic H-Loop technique significantly restores function, improves range of motion, and enhances internal rotation strength, maintaining good tendon integrity in the early postoperative period.
