Advanced Orthopaedic Specialists - Harrison

Dr. Terry Sites, Dr. Christopher Arnold, Dr. Mark Powell, and Dr. Ramon Ylanan are the AOS – a group of three MD orthopaedic surgeons and one primary care sports medicine specialist with advanced fellowship training in sports medicine.

The AOS has a combined 60 year history of success in the practice of sports medicine, joint replacement, shoulder repair, knee reconstruction, cartilage restoration, fracture care, and more.

We are experts in the areas of minimally invasive techniques and most surgeries are performed on an outpatient basis at the Physicians’ Specialty Hospital (PSH). The PSH is a unique state of the art surgical facility devoted to only a few specialty areas and allows focused care that can not be matched by large general hospitals.

  • Love it!!
    The office staff is incredibly courteous and professional. I was able to get an appointment the same day I called after not being able to get into another clinic for several days. Dr. Ylanan was great about getting my MRI scheduled quickly...most people wait months to get surgery and I was diagnosed and surgically treated within 2 weeks! The surgery went great and I am on the road to recovery. I really appreciated Dr. Arnold calling me the evening of my surgery to check on me and let me know my surgery went well.
