ARJR Fellowship Program

The Fellowship Match ProgramThe Adult Reconstruction and Joint Replacement Fellowship Program at HSS

The Adult Reconstruction and Joint Replacement Fellowship Program at HSS was established over 45 years ago to train future thought leaders in total joint replacement surgery while perfecting surgical and technical skills. The Program is accredited by the Accreditation Council for Graduate Medical Education (ACGME). Led by 21 full-time surgeons, specialty-trained in hip and knee replacement and with a collective volume of over 8,700 cases per year, the Program provides an opportunity for Fellows to gain a broad range of in-depth experience.

One of the largest divisions at the Hospital, the Adult Reconstruction and Joint Replacement Service is composed of the Hip Service, the Knee Service, and the Surgical Arthritis Service and performs the majority of the adult reconstructive surgery cases at HSS. HSS’s affiliation with NewYork-Presbyterian Healthcare System and Weill Cornell Medical College provides Fellows with the unique resources of this rich academic and scientific community.

Clinical Training

Each Fellow is involved in an average of over 500 cases (half hip, half knee), of which approximately fifteen percent are complex revisions. Fellows rotate among each of the 21 members of the Adult Reconstruction and Joint Replacement Service, which performs the majority of the adult reconstructive surgery cases at HSS and is one of the busiest operative services at the Hospital. Some of the complex cases require an interdisciplinary approach, involving close collaboration among the orthopaedic surgeons, radiologists, and the Hospital’s bioengineers.

A Fellow can expect significant exposure to a broad range of surgical procedures, from primary and revision hip and knee replacements to new techniques, such as minimally invasive total knee and total hip replacements, unicondylar knee replacement, hip resurfacing, hip and knee arthroscopy, custom implants, and computer assisted surgery. HSS utilizes implants from a wide variety of sources to achieve the best possible outcomes, adding to the breadth of Fellows’ experiences. Fellows train and work in state-of-the-art operating rooms, custom-designed by HSS surgeons with a single purpose in mind- to advance orthopaedic surgery. Participation in outpatient visits, including both private office and clinic settings, along with intense operating room experience, provides Fellows with wide practice in the diagnosis, treatment, and follow-up of a diverse patient population. In addition to clinical care, Fellows develop strong teaching and organizational skills necessary to participate in an academic career, as well as techniques for running and managing a practice.

Adult Reconstructive and Joint Replacement Fellowship Faculty

Our internationally prominent faculty serve in an array of regional, national, and international educational capacities and have published papers and books in their specialties and related areas. This breadth of experience and knowledge, as well as many decades of expertise, translates into state-of-the-art training of Fellows.


With more than 350,000 patient visits each year, Hospital for Special Surgery is uniquely positioned to conduct clinical research that incorporates state-of-the-art patient care, while evaluating how best to apply the newest innovations in orthopaedics and rheumatology. Over 80 percent of the Hospital’s joint replacement patients are currently enrolled in one of the Hospital’s registry databases.

Six key areas have been identified for Division-wide research focus: partial knee replacement, perioperative processes, bone restoration, registries/outcomes, osteoarthritis, and osteolysis. Currently, members of the ARJR Service are pursuing some 70 different research projects.

Fellows build upon their existing research skills with extensive exposure to research methodology, study design, and critical data review. The Program sets aside one day per week for this work, thereby protecting 20 percent of a Fellow’s time for research.

Upon entering the Program, Fellows are assigned a research mentor and IRB-approved projects and are expected to pursue at least two research projects- one clinical and one in biomechanics- during the fellowship year. Fellows are also encouraged to attend and present research at national and international academic meetings, and funding is available for Fellows to attend at least two conferences per year. Yearly, the highly-respected work of Fellows, along with other members of the Service, is published in peer-reviewed articles and abstracts, which are accepted to international and domestic conferences.

Alumni Network

The ARJR Fellowship Program has a thriving network of alumni in academic and clinical settings across the country and world. Our Fellows now practice in a variety of academic and community centers, such as the Mayo Clinic, Massachusetts General Hospital, Cleveland Clinic, NewYork-Presbyterian/Columbia University Medical Center, Lahey Clinic, McGill University, and Georgetown University, as well as here at HSS.

Living in New York City

The New York City setting, one of the most economically and culturally diverse metropolitan areas in the world, provides Fellows with the opportunity to work with patients from a variety of religious, ethnic, and socio-economic backgrounds.

Our Program is situated in New York City’s Upper East Side, which consists of both commercial and residential areas, many of which are populated by families with school-aged children. The area offers abundant resources for families (schools, childcare, playgrounds, parks, and recreational activities). Many of the world’s most highly regarded cultural institutions are within walking distance or a short bus, subway, or cab ride away from the Hospital.
