Clinical and Radiologic Outcomes After Medializing and Not Medializing Rotator Cuff Tendon Attachment Site on Chronic Retracted Rotator Cuff Tears.
Arthroscopy 2018 August
PURPOSE: To compare the clinical and radiologic outcomes of chronically retracted rotator cuff tears by arthroscopic medializing and non-medializing repair (restoring anatomic footprint and performing conventional repair).
METHODS: This study retrospectively reviewed 195 patients who underwent arthroscopic double-row modified Mason-Allen repair for large, full-thickness rotator cuff tears from January 2013 to July 2015. We included a total of 60 of these patients and divided them into 2 groups: those who underwent medialization (n = 24) and those who did not (n = 36). Magnetic resonance imaging was performed at a minimum of 6 months (mean, 15.2 months; range, 6-24 months) postoperatively to assess cuff integrity. Patients were clinically evaluated at least 1 year postoperatively (mean, 18.9 months; range, 12-60 months) with a visual analog scale, the American Shoulder and Elbow Surgeons score, the University of California-Los Angeles Shoulder Rating Scale score, and the Constant score.
RESULTS: The mean medialization length was 10.5 mm (range, 6.5-15.6 mm) on magnetic resonance imaging. The retear rate was 8.3% (n = 2) in the medialization group and 31% (n = 11) in the non-medialization group (P = .041). At last follow-up, the mean visual analog scale, American Shoulder and Elbow Surgeons, University of California-Los Angeles, and Constant scores improved significantly from 5.3 ± 1.4, 38.5 ± 8.8, 22.5 ± 3.1, and 41.7 ± 9.9, respectively, to 1.8 ± 1.1, 85.3 ± 7.5, 31.8 ± 2.5, and 90.2 ± 6.9, respectively, with medialization and from 4.0 ± 1.6, 51.5 ± 10.5, 20.0 ± 3.9, and 55.9 ± 10.5, respectively, to 1.4 ± 1.0, 88.6 ± 9.0, 31.0 ± 9.3, and 89.4 ± 9.3, respectively, with non-medialization (P < .001), although there were no significant differences between the groups (P = .165, P = .653, P = .250, and P = .113, respectively).
CONCLUSIONS: Medialization of approximately 10.5 mm reliably shows good clinical results, and medializing rotator cuff tendons should be considered as a treatment option for repairing rotator cuff tears with chronic retracted tendons.
LEVEL OF EVIDENCE: Level III, retrospective comparative study.
