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.
