Retrospective analysis of arthroscopic repair outcomes using a modified Mason-Allen suture bridge "parachute" technique with bone marrow stimulation for rotator cuff tears.

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
objectiveRotator cuff tear (RCT) is a prevalent source of shoulder pain and functional limitation, with postoperative tendon healing continuing to present significant challenges. This study aims to retrospectively evaluate the clinical and imaging outcomes of RCT treatment at our institution, employing a modified Mason-Allen suture bridge technique in combination with bone marrow stimulation (BMS).
methodsA retrospective study was conducted involving patients with RCT who underwent arthroscopic modified Mason-Allen suture bridge repair, also referred to as the "parachute" technique, combined with BMS at our institution between January 2021 and January 2023. Exclusion criteria included preoperative magnetic resonance imaging (MRI) demonstrating Goutallier grade 3 or higher fatty infiltration, a history of shoulder surgery, the presence of degenerative arthritis, or rotator cuff lesions. A total of 47 patients met the inclusion criteria, of whom 44 completed a minimum follow-up period of 24 months. Preoperative and 24-month postoperative data were obtained from electronic medical records and outpatient follow-up systems. These data encompassed the American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE), Visual Analog Scale (VAS) for pain, Japanese Orthopaedic Association (JOA) score, shoulder range of motion in flexion, external rotation, and internal rotation, as well as postoperative MRI assessments to evaluate tendon healing status.
resultsCompared to preoperative measurements, patients exhibited significant improvements in VAS, SANE, ASES, and JOA scores, as well as in all ranges of motion at 24 months postoperatively (P < 0.05). In the final follow-up, MRI assessment employing the Sugaya classification demonstrated that all 44 patients (100%) exhibited healing (types I-III), with no instances of re-tear (types IV-V) observed. Throughout the study period, no instances of nerve or vascular injury, wound infection, or complications related to suture anchors were observed.
conclusionThis retrospective analysis indicates that the rotator cuff repair strategy, which integrates the "parachute" technique with BMS, results in significant functional improvement and consistent imaging-confirmed healing during follow-up, accompanied by a low incidence of complications. This retrospective analysis suggests that combining the "parachute" technique with BMS constitutes a safe and clinically viable approach for rotator cuff repair, thereby providing a basis for future prospective comparative investigations.
