Research

Dr. Mazzocca's research is based on his experience with patient outcomes, diagnosis and treatment - operative and nonoperative. In all of these areas, Dr. Mazzocca looks for ways to improve the standard of care for patients to have a more efficient return to activity or provide an improved technique, which results in better overall outcomes for their lives. Dr. Mazzocca does this by dividing his research into three distinct clinical areas.

  1. Cell biology: looking at new biologic solutions to bone tendon healing involving Platelet Rich Plasma (PRP), bone marrow and various other healing cells.
  2. Biomechanics: evaluating the strength and durability of surgical repairs, also evaluating new and improved surgical techniques for all areas of the musculoskeletal system.
  3. Clinical outcomes: evaluating the data collected from patients on how much their specific pain has improved and how fast they were able to get back to work and sports.
  4. Dr Mazzocca's research interests include a clinical focus on shoulder instability and arthritis, elbow and rotator cuff injury and repair, and shoulder surgery outcomes. It also includes a component of surgical education improving teaching of our medical students, residents and fellows. Local, national and international collaborations are extremely important to Dr. Mazzocca's research efforts and a mainstay of the labs he directs. Dr Mazzocca has patents on processes designed to improve healing of rotator cuff repairs, as well as devices that aid in shoulder joint reconstruction.

My experience with Dr. Gus Mazzocca was fine. He was very thorough and we got in as soon as we arrived. We had a very short visit to wait and he was very pleasant and very thorough. Very happy with him.

I am very impressed with Dr. Mazzocca. He explained everything thoroughly and he gave me much optimism with regard to the outcome of my surgery. Dr. Mazzocca is an excellent doctor and I would recommend him to anyone needing an orthopedic surgeon.

Dr. Mazzocca was absolutely amazing! He had obviously studied my case before I saw him. He was very caring as well as very thorough in discussing my injury. In a very clear manner he laid out my options, gave his preference and asked me what my option was. We were in total agreement. I felt very fortunate to have been referred to him by my ... Read More

I've had experience with this doctor for over 20 years and would love to have another 20 years with him. He is awesome.

Dr. Mazzocca has a personality that I believe everyone would love, especially for a (top) surgeon. He takes his time with you, subjectively and objectively. He explains what he sees, and shows it to you on your MRI. The only tool that I think would be beneficial would be a plastic model of the shoulder showing the ligaments and tendons. I have ... Read More

February 2025

Dr Mazzocca was a pleasure to meet with. I have already told my children who are all parents themselves now if they need a shoulder doc he's the one to see. From the moment in entered his office I felt very well cared for. His expertise is expressed in many ways. He was already aware of my medical history. He was happy which conveys a sense to the ... Read More
