Mark Ayzenberg, MD, FAAOS, is a Board-Certified, Orthopaedic Surgeon at Premier Orthopaedic Associates who specializes in Sports Medicine, Arthroscopy, and Reconstructive Surgery. His practice focuses on minimally invasive (arthroscopic “key- hole”) surgery of the shoulder, knee, hip, and ankle, as well as total joint replacements of the shoulder, knee and hip. He also treats general orthopaedic trauma, including dislocations and fractures.  

Dr. Ayzenberg is a specialist in all shoulder arthroscopic procedures, including rotator cuff repair, instability surgery and complex reconstructive surgery such as superior capsular reconstruction and dermal allograft reconstruction. He is an expert in joint-sparing surgery to avoid shoulder replacements whenever possible.  In patients with advanced shoulder arthritis that may not be improved with arthroscopic surgery, Dr. Ayzenberg utilizes patient-specific technology and computer planning guidance to perform a shoulder replacement tailored to each patient’s unique anatomy and needs. 

Dr. Ayzenberg also treats knee injuries, such as ACL (anterior cruciate ligament) and other ligamentous injuries, and performs meniscus surgery and cartilage restoration. For all of these surgeries, he employs minimally invasive arthroscopic surgery as well, whenever possible. When a patient has advanced arthritis that cannot be treated with arthroscopy, Dr. Ayzenberg provides options to avoid joint replacement whenever possible, including utilization of platelet-rich-plasma (PRP), and other orthobiologics.

For patients with conditions of the hip and ankle that can be treated with a minimally invasive approach, Dr. Ayzenberg specializes in hip arthroscopy for femoroacetabular impingement and labral tears of the hip, as well as ankle and subtalar arthroscopy for cartilage restoration, instability and impingement of the ankle. 

Dr. Ayzenberg graduated cum laude with a Bachelor of Arts degree in Biology from the University of Pennsylvania in Philadelphia. He then completed medical school at the The Commonwealth Medical College in Scranton, PA as a Doctor of Medicine and graduated with highest honors, at the top of the class.

Dr. Ayzenberg trained at the prestigious Sports, Arthroscopy and Reconstructive Surgery fellowship at the Southern California Orthopedic Institute (SCOI). Prior to his fellowship, Ayzenberg completed his residency at the Einstein Healthcare Network in Philadelphia, where he served as Academic Chief Resident. He has an active interest in advancing the field of Sports Orthopedic Surgery and has multiple scientific publications, several of which have been presented at national orthopaedic meetings.

Presently, Dr. Ayzenberg serves as the Assistant Team Physician for the Philadelphia Wings Professional lacrosse team. Previously, he worked as Assistant Team Physician for several college and high school teams.
