Predictive factors of total shoulder arthroplasty failure: My crystal ball

As total shoulder arthroplasty has become more popular, the number of complications and failures are increasing. Surgeons performing the procedure and patients considering the surgery need to understand the factors that may determine success or failure. The most common predictors of failure are the indication for surgery (patient factors), the type of implant used (arthroplasty implant factors), and the skill of the surgeon (surgical factors). The aim of this review is to delineate the factors that may be associated with an increase in the risk of total shoulder arthroplasty failure.
