Editorial Commentary: Adverse Events After Rotator Cuff Repair Are Not Rare: Houston, We (May) Have a Problem.

Abstract

The first national medical database registry was started in Sweden in 1975, and clinical registries have gained enormous popularity. Analysis of a large database of rotator cuff repair surgeries shows that adverse events may occur in almost 1 of 5 cases, showing the use of a register as a highly beneficial source of information. However, retrospective review of prospectively collected registry data has limitations and biases as well as benefits, including inconsistent reporting and recording of data, lack of control of confounding patient variables, and loss to follow-up.
