ObjectiveTo investigate effectiveness of rotator cuff repair with manipulation release and arthroscopic debridement for rotator cuff tear with shoulder stiffness.MethodsA retrospectively study was performed on the data of 15 patients with rotator cuff tear combined with shoulder stiffness (stiff group) and 24 patients without stiffness (non-stiff group) between January 2014 and December 2015. The patients in the stiff group underwent arthroscopic rotator cuff repair with manipulation release and arthroscopic debridement while the patients in the non-stiff group only received arthroscopic rotator cuff repair. The patients in the stiff group were older than the patients in the non-stiff group, showing significant difference ( P<0.05). There was no significant difference in gender, type of rotator cuff tear, side of rotator cuff tear, and combined with diabetes between 2 groups ( P>0.05). The visual analogue scale (VAS) score, University of California Los Angeles (UCLA) score, American Shoulder and Elbow Surgeons (ASES) score, and range of motion (ROM) were used to evaluate the effectiveness after operation.ResultsAll incisions healed by first intention without any complication after operation. The patients were followed up 13-31 months in the stiff group (mean, 19.2 months) and 13-23 months in the non-stiff group (mean, 20.3 months). There was no significant difference in follow- up time between 2 groups ( t=-0.573, P=0.570). The VAS score in the stiff group was higher than that in the non-stiff group before operation ( t=-2.166, P=0.037); there was no significant difference between 2 groups at 3, 6, 12 months and last follow-up ( P>0.05). The forward flexion and external rotation were significantly lower in the stiff group than those in the non-stiff group before operation and at 3 months after operation ( P<0.05); there was no significant difference between 2 groups at 6, 12 months and last follow-up ( P>0.05). At last follow-up, the internal rotation was beyond L 3 level in 2 groups. The preoperative UCLA score was significant lower in the stiff group than that in the non-stiff group ( P=0.037); but there was no significant difference in UCLA score at last follow-up between 2 groups ( P=0.786). There was no significant difference in pre- and post-operative ASES scores between 2 groups ( P>0.05).ConclusionSatisfactory effectiveness can be achieved in the patients with rotator cuff tear combined with shoulder stiffness after rotator cuff repair with manipulation release and arthroscopic debridement, although the patients with shoulder stiffness had slower postoperative recovery of ROM until 6 months after operation.
