Which factors can significantly impact the longevity of a TSA implant?

The longevity of a Total Shoulder Arthroplasty (TSA) implant is significantly influenced by the patient’s activity level and the materials used in the implant.

A patient’s activity level directly affects how much stress is placed on the shoulder joint. Higher activity levels may lead to increased wear and tear on the implant, potentially shortening its lifespan. Conversely, lower activity levels can result in a longer-lasting implant.

The materials used in TSA implants are critical as well. Advanced materials, such as high-performance polyethylenes and metal alloys, can resist wear and corrosion, leading to improved longevity. For instance, innovative bearing surfaces are engineered to minimize friction and provide better durability over time.

Other factors, such as patient age, surgical technique, and prosthesis design, certainly play roles in outcomes but are less directly correlated with longevity compared to activity levels and the properties of the materials used in the implant itself.
