Why is soft tissue balance important in TSA?

Soft tissue balance is essential in Total Shoulder Arthroplasty (TSA) because it directly influences the stability and functionality of the shoulder joint. Proper soft tissue balance ensures that the muscles, tendons, and ligaments surrounding the joint maintain coordinated movement and strength, which are critical for optimal performance of the implanted prosthesis.

When the soft tissues are balanced, it contributes to the correct positioning of the components of the shoulder implant, allowing for natural motion and effective force transfer during activities. A well-balanced shoulder joint can lead to improved range of motion, reduced discomfort, and a lower likelihood of complications such as instability or dislocation post-surgery.

Improper soft tissue balance, on the other hand, can lead to asymmetric loading of the implant, resulting in uneven wear, pain, and reduced overall joint function. Therefore, achieving an optimal balance in the soft tissues is key to the long-term success of the surgery, which is why it is a focal point for surgeons performing TSA.
