What potential impact can TSA have on shoulder biomechanics?

The impact of Total Shoulder Arthroplasty (TSA) on shoulder biomechanics is most accurately represented by alterations in range of motion and stability. After the procedure, patients typically experience changes in how the shoulder joint moves and feels, influenced by the new materials and configurations of the implant.

TSA is designed to relieve pain and restore function, but it is important to note that while patients may gain improved range of motion, this does not guarantee a full return to pre-injury function due to various factors such as muscle strength, soft tissue integrity, and overall joint mechanics.

The surgery can enhance stability, as properly implanted prostheses can help achieve a more secure articulation in the shoulder, which may not have been present in a pre-operative condition affected by arthritis or injury. Therefore, the most accurate assessment of TSA's effects on biomechanics emphasizes these changes in both range of motion and joint stability, reflecting the complexity of recovering from and adapting to surgical intervention.
