Background: The aim of this study was to identify the clinical outcomes after conservative management of partial tears of the upper subscapularis tendon (Pfirrmann class I) in patients who underwent arthroscopic repair of rotator cuff tears.
Methods: Of the two hundred and eighty-one patients who underwent arthroscopic rotator cuff repair at our institution between January 2005 and August 2011, fifty-six patients had a subscapularis tendon tear. And among them, twenty-three patients who could be followed up until at least 12 months after operation were evaluated retrospectively. Repair of the subscapularis tendon partial tear was not performed in all patients. We evaluated the range of motion (ROM) of shoulder, muscle power, Korean shoulder scoring system (KSS), American Shoulder and Elbow (ASES) scores, and the visual analog scale (VAS).
Results: At 12-months follow-up, range of forward elevation was improved to 148.5o, range of external rotation to 55.4o, and range of internal rotation to the 11th thoracic level. Further, abduction strength was improved to 13.9 kg, external rotation strength to 16.4 kg, and internal rotation strength to 18.4 kg. KSS was improved from 53.0 to 89.4, ASES from 48.4 to 86.6, and VAS from 8.3 to 1.6. There were significant improvements in terms of ROM of shoulder, muscle power, KSS, ASES scores, and VAS (P < 0.05).
Conclusion: Clinical improvement was achieved in patients with arthroscopic repair of rotator cuff tears at a short-term follow-up of 12 months when the partial tear in the upper subscapularis tendon (Pfirrrmann class I) that came concomitantly was conservatively managed.
