Summary: | Superior capsular reconstruction (SCR) has recently gained popularity as a surgical solution for patients with massive rotator cuff tears or shoulder pseudoparalysis (PPS). Good clinical outcomes have been reported after SCR; however, the factors that influence its clinical outcomes remain unclear. Therefore, in this study, we aimed to clarify the factors influencing postoperative outcomes after SCR using tensor fascia lata graft, for which we evaluated the Hamada grade, patients with or without PPS, and the status of the subscapularis tendon (SSC).
In total, 54 consecutive patients with irreparable rotator cuff tears or PPS who underwent SCR between June 2014 and October 2018 were included. The enrolled patients were grouped and compared as follows: (1) Hamada grade 2 (11 patients) and Hamada grade 3 (43 patients) and (2) non-PPS (22 patients), moderate PPS (16 patients), and severe PPS (16 patients). For subanalysis, the 32 PPS patients were divided into 3 groups: intact SSC (11 patients), repairable SSC (16 patients), and irreparable SSC (5 patients). To assess shoulder function, the American Shoulder and Elbow Surgeons (ASES) score was evaluated before surgery and at 24 months postoperatively; shoulder range of motion was evaluated at 2, 3, 4, 5, 6, 8, 10, 12, and 24 months postoperatively.
No significant differences in postoperative ASES scores and shoulder range of motion were observed between the Hamada grade 2 and grade 3 groups or between the non-PPS, moderate PPS, and severe PPS groups. However, significant differences in postoperative shoulder elevation and ASES scores were observed between the intact SSC and irreparable SSC groups (P = .006) and between the repairable SSC and irreparable SSC groups (P = .003).
This study demonstrated that the status of the SSC, rather than the Hamada grade or the presence or absence of PPS, influences the clinical outcomes after SCR. Therefore, reparability or intactness of the SSC is an important factor in considering the surgical indication for SCR. |
