Biomechanical influence of surgical and graft-related factors in superior capsule reconstruction: A systematic review.
Review in Journal of experimental orthopaedics, 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
Purpose: Arthroscopic superior capsule reconstruction (ASCR) is a surgical option for the treatment of irreparable rotator cuff tears. This systematic review aimed to synthesize the available biomechanical evidence on ASCR, especially on the influence of surgical and graft-related factors on shoulder biomechanics and graft mechanics. It was hypothesized that graft type, dimensions and concomitant procedures affect postoperative biomechanics following ASCR. Methods: A systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines using PubMed, Web of Science, Scopus, Cochrane Library and Ovid databases. Eligible studies included cadaveric, in vitro, in vivo and in silico biomechanical studies evaluating ASCR-related factors. Animal studies, clinical outcome studies and comparisons with alternative techniques were excluded. Results: A total of 37 biomechanical studies were included. Investigated factors comprised concomitant procedures (29.3%), graft type (26.8%), shoulder position of fixation (22.0%), graft thickness (12.2%) and fixation technique (9.8%). Most studies used cadaveric models (86.5%) under quasi-static conditions with simplified muscle-loading protocols and assessed outcomes at three to five shoulder positions in the frontal plane. Most studies focused on the spacer role of the graft in limiting superior humeral head translation, while its contribution to humeral head centring and dynamic force redistribution was overlooked. Fascia lata grafts were generally associated with improved joint stability and reduced subacromial contact pressures. The shoulder position of fixation influenced joint stability, and concomitant procedures were required to restore anterior-posterior stability. Substantial heterogeneity in experimental protocols, outcome measures and reporting practices limited a direct comparison across studies. Conclusions: The current biomechanical evidence on ASCR remains constrained by methodological simplifications and the isolated, rather than combined, assessment of ASCR-related factors. Available data suggest that graft type and dimensions, and the performance of concomitant procedures restoring capsule continuity, influence the recovery of joint stability. Level of Evidence: Basic science study: biomechanics.
