Related Factors and Therapeutic Effect of Rotator Cuff Delamination

Abstract

Objective: This study aims to explore the related factors and treatment result of RCT with delamination. Materials and methods: From February 2016 to July 2019, a total 155 patients with RCT were enrolled into the present study. Among these patients, 66 were male and 89 were female, and their an average age was 56.4±7.8 years old (41-75 years old). The medical history of each patient was recorded before the operation, and the joint function was evaluated using the Constant score table. During the operation, the RCT was examined using an arthroscope, the delamination was evaluated, and the RCT type was classified. A proper suture technique was executed for these different types of rotator cuff injuries, and routine functional exercises were performed after the operation. Poisson chi-square test was used to analyze the related factors of delamination, and t-test was used to analyze the result of the treatment. Results: Among the 115 patients, 47 patients had delamination, while 68 cases had no delamination. The larger the RCT size, the greater probability of delamination. Furthermore, the delamination probability of a RCT with subacromial impact would also increase. However, there was no statistical correlation between disease history or trauma and delamination. All patients achieved good therapeutic results. Conclusion: The incidence of rotator cuff delamination remains high, and the occurrence of delamination is correlated to the size of the tear, and the determination of whether this is accompanied by subacromial impact. However, there is no correlation between delamination and trauma or disease duration. For rotator cuff tears with delamination, reasonable surgical techniques can be used to treat the rotator cuff injury, in order to obtain a good effect.Level of evidence: Level III, Retrospective Cohort Design, Treatment Study
