Abstract:

Objective To investigate the effect of symptom duration of rotator cuff tear with frozen shoulder on clinical efficacy of rotator cuff repair with manipulation release and to provide reference for operation timing. Methods eighty patients which rotator cuff repair under manual release were retrospectively analyzed. They were divided into A group（n = 40）the duration was less than or equal to 3 months）and B group（n = 40：the duration was more than 3 months and less than 6 months）. VAS，ASES and Constant⁃Murley scores were compared before operation and post operation to evaluate the efficacy. Results The two groups of patients successfully went through the operation. The VAS scores of patients in both groups at 6 weeks，3 months and 6 months after operation grew gradually lower than those before operation（P < 0.05），and ASES and Constant⁃Murley score increased gradually higher than those before operation（P < 0.05）. There was no statistical difference in VAS and ASES score between the two groups（P > 0.05）. The statistical difference of constant⁃Murley score was significant only at 6 weeks after operation（P < 0.05）. Conclusion The patients with the duration is less than or equal to 3 months can get the improvement of shoulder join activity earlier than the patients with the duration of more than 3 months and less than 6 months，but there is no significant difference concerning the long term curative effect.
