How is shoulder stability maintained post-TSA?

Shoulder stability after Total Shoulder Arthroplasty (TSA) is primarily maintained through proper alignment and soft tissue integrity. This involves ensuring that the components of the shoulder implant are positioned correctly in relation to one another, which helps in maintaining the natural biomechanics of the shoulder joint. Moreover, the surrounding muscles, ligaments, and tendons play a crucial role in stabilizing the joint. Preserving the integrity of these soft tissues is essential because they contribute to the dynamic stability of the shoulder during motion.

In contrast, relying solely on a sling or attempting to completely limit movement can hinder the recovery process and may not address the underlying issues of stability. While physical therapy is very important for regaining strength and range of motion, it is not sufficient on its own without proper alignment and soft tissue support. Therefore, both mechanical alignment through the surgical placement of components and the biological integrity of the surrounding soft tissues are key to ensuring shoulder stability after TSA.
