Which aspect is critical in determining appropriate candidates for TSA?

Determining appropriate candidates for total shoulder arthroplasty (TSA) primarily hinges on the patient's condition and activity level. This aspect is critical because the success of the procedure is strongly influenced by the individual's overall health, the severity of their shoulder condition (such as osteoarthritis or rotator cuff disease), and their functional demands.

A thorough assessment of the patient's condition includes understanding the extent of their joint degeneration, pain levels, and how these factors affect their daily activities. Likewise, the patient's activity level plays a significant role in evaluating their potential post-operative outcomes. For instance, an active patient who relies on shoulder function for sports or manual work may have different needs compared to a less active individual.

This evaluation not only helps in selecting candidates who are more likely to benefit from TSA but also guides preoperative planning, rehabilitation protocols and can impact the choice of the specific implant used during the procedure. Knowing the patient's functional goals and limitations ensures that the surgical intervention aligns with their expectations and lifestyle, thereby enhancing overall satisfaction and outcomes following surgery.
