- To compare clinical outcomes after surgical treatment between rotator cuff tears with and without shoulder
stiffness and evaluate the serial changes in pain intensity, functional scores, and range of motion (ROM). Methods: The
study comprised 26 patients with preoperative stiffness (stiff group) and 26 patients without stiffness (non-stiff group).
The stiff group underwent arthroscopic or mini-open rotator cuff repair with arthroscopic capsular release and manipulation.
The non-stiff group with rotator cuff repair only was matched for age and sex with the stiff group. The visual
analog scale (VAS) pain score; University of California, Los Angeles (UCLA) score; American Shoulder and Elbow Surgeons
(ASES) score; and ROM were evaluated preoperatively; 3, 6, and 12 months after surgery; and at final follow-up.
Results: Both groups had significant improvements in the VAS pain score, UCLA score, ASES score, and ROM at final
follow-up. There were no significant differences between the 2 groups regarding VAS pain score, UCLA score, and ASES
score at any period after surgery. In the stiff group, mean forward flexion was significantly lower than that in the non-stiff
group at 3 months after surgery (143.1 v 154.2 , P ¼ .003). Mean external rotation and internal rotation were significantly
lower than those in the non-stiff group at 3 months after surgery (37.9 v 44.2 , P ¼ .043, and 15.8 v 13.9, P < .001,
respectively) and 6 months after surgery (49.1 v 57.3 , P ¼ .002, and 13.2 v 12.0, P ¼ .033, respectively).
Conclusions: Overall satisfactory clinical outcomes could be achieved in both the stiff and non-stiff groups, although the
stiff group had slower postoperative recovery of ROM until 6 months after surgery. Level of Evidence: Level III,
retrospective comparative study, prognosis study.
