Popis: Objective Treatment of massive irreparable rotator cuff tears (RCT) has shown limited clinical success and a variety of subsequent complications. Superior capsule reconstruction (SCR) has been proved to reestablish superior stability but does not restore the dynamic force or shoulder kinematics. There are numerous reports of the short‐term failure of SCR grafts at the glenoid side, which relate to the non‐biological healing of grafts. To restore both dynamic and static stability and to provide biologic augmentation, an integrated procedure for massive irreparable RCT using an Achilles tendon–bone allograft (ATBA) was developed. Method This was a retrospect study completed between October 2019 and April 2020. A 71‐year‐old woman with massive and irreparable rotator cuff tears was enrolled in our study. The ATBA was folded into a double‐layer structure. The superior layer (proximal portion) served as a bridge patch to dynamic the glenohumeral joint, while the inferior layer (distal portion) served as the superior capsule to restore static stability of glenohumeral joint. To enhance biologic healing on the glenoid side, we fixed the calcaneus of the graft on the superior–posterior side of the superior glenoid rim. The recovery of shoulder function (including strength, range of motion, acromiohumeral interval, and fatty infiltration) was assessed at 6 months postoperation. Result At 6‐month follow‐up, the patient's strength had improved significantly (from abduction of grade 3 preoperatively to grade 4 at 6 months). Radiographic analysis showed an increase in the acromiohumeral interval from 3 to 7 mm. Magnetic resonance imaging revealed an intact graft, with the thickness of the ligament part maintained (at 6–7 mm). Most importantly, recovery of atrophy and fatty infiltration of the supraspinatus were observed. No graft tears were observed on the glenoid side. Conclusion This technique could provide a preferable treatment option by restoring shoulder kinematics and augmentating biological healing for patients with massive irreparable RCT.
