When it comes to cutting-edge orthopedic care, Dr. Alfred Cook stands at the forefront of shoulder surgery, sports medicine, and cartilage regeneration. As the Chief of Orthopedic Surgery at UF Health Spanish Plaines Hospital and the Medical Director for the TLC Surgical Center, Dr. Cook has earned a reputation as a leader in advanced surgical techniques. His passion for improving joint health and mobility drives his commitment to helping patients—whether they are athletes recovering from injuries or older adults seeking relief from chronic pain.

Among his many contributions to the field, Reverse Total Shoulder Arthroplasty (RTSA) is one of the most groundbreaking procedures Dr. Cook specializes in. This advanced surgical technique has transformed the lives of patients who previously had limited treatment options due to severe rotator cuff damage or arthritis.

What is Reverse Total Shoulder Arthroplasty (RTSA)?

RTSA is a specialized form of shoulder replacement surgery that utilizes the latest advancements in implant design and surgical precision. Unlike traditional shoulder replacements, which require an intact rotator cuff, RTSA is specifically designed for patients with irreparable rotator cuff damage, severe arthritis, or complex fractures.

This procedure was introduced in the U.S. about 20 years ago and has since become a revolutionary solution for many patients. Dr. Cook has played an instrumental role in refining RTSA techniques, collaborating with leading medical technology companies to develop innovative implants that improve patient outcomes.

How RTSA Differs from Standard Shoulder Replacement

In a traditional shoulder replacement, the damaged parts of the shoulder joint are replaced with artificial components that mimic the body’s natural anatomy—a round ball component fits into a socket, allowing smooth movement. However, this approach relies on a healthy rotator cuff to stabilize and move the joint.

RTSA takes a different approach:

The ball and socket positions are reversed—the artificial ball is placed where the socket was, and the socket is positioned where the ball was.

The socket is placed on the arm side of the joint and is supported by a metal stem implanted in the humerus (upper arm bone).

This reversal allows the deltoid muscle (instead of the damaged rotator cuff) to take over shoulder movement, providing stability, pain relief, and restored function.

Because RTSA does not rely on an intact rotator cuff, it is a highly effective solution for patients with severe rotator cuff injuries combined with arthritis—conditions that would make a standard shoulder replacement unsuccessful.

Who is a Candidate for RTSA?

RTSA is an excellent option for patients who experience:

• Irreparable rotator cuff tears that prevent normal shoulder movement.
• Severe osteoarthritis, leading to joint deformities and debilitating pain.
• Rheumatoid arthritis (RA), an autoimmune disease that deteriorates joint tissue.
• Complex shoulder fractures, especially those that are unlikely to heal correctly.
• Persistent pain and loss of function that do not respond to conservative treatments like medication, injections, or physical therapy.

For many patients, pain is the primary reason they seek treatment from Dr. Cook. With RTSA, they can regain their mobility and significantly improve their quality of life.
