Mark Ayzenberg, MD, FAAOS is a Board-Certified Orthopaedic Surgeon specializing 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. He also routinely treats general orthopaedic trauma, including complex 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 arthroscopy for cartilage restoration, instability and impingement of the ankle.  


Dr. Ayzenberg focuses on returning his patients to the activities they love to do with the least-invasive means possible, resulting in a faster recovery, less pain and downtime.  He uses orthobiologics, cellular therapy, PRP (Platelet Rich Plasma), and BMAC (Bone Marrow Aspirate Concentrate) to treat joint, muscle and tendon pain resulting from injuries as well as arthritis and wear and tear - these therapies can often improve pain and function without pills or surgery for many conditions.  He founded Iron Mountain Regenerative Orthopaedics for this reason and you can review information regarding orthobiologics at

Dr. Ayzenberg's has two main mottos in his approach to patient care:

"I don't treat pictures, I treat patients" - many people may have tears and other injuries on their x-rays and MRIs, but these very often do not require surgery.  Treating the picture (ie. the MRI) is not in the best interest of the patient.


"Less is more - less pills, less shots, less surgery whenever possible." 


Although he is a surgeon, Dr. Ayzenberg focuses on the least invasive way of treating his patients and returning them to the activities that make them happy.  He has excellent testimonials both from patients who required surgery and those who did not - this is all because he does not rush to conclusions and focuses on the patient's goals and needs with a team approach to patient care.

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 Geisinger Commonwealth School of Medicine 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 dozens of scientific publications, several of which have been presented at national orthopaedic meetings.


Dr. Ayzenberg is experienced in the care of professional athletes, having served as a team physician for the Philadelphia Wings Professional Lacrosse Team.


Dr. Ayzenberg holds medical licenses in Pennsylvania and New Jersey. He is fluent in Russian and can speak basic Spanish.

"My priority is to return my patients as quickly as possible to activities that fulfill them in their daily lives, using the least invasive techniques available, the highest quality of surgery when necessary, and a supportive bedside manner."
