About the Department of Orthopaedic Surgery
About
The mission of the Department of Orthopaedic Surgery has three main arms. They are:
- to offer excellent care to all the patients we serve,
- to provide superb clinical and academic education and training to its residents,
- and to advance the field of orthopaedic surgery through contributions to research.
For nearly a half a century, the department has been continuously making strides towards these goals. We boast the premiere site for orthopaedic training in the state of New Jersey, and the diverse paths that our residents take are a testament to the breadth and depth of training they receive here. The faculty at Robert Wood represent a healthy mix of talented physicians trained all over the country, as well as at Robert Wood Johnson. The diversity in their training serves to amplify the training experience our residents receive.

In line with our mission to foster camaraderie among students interested in orthopaedics, OSIG hosts student-only panels to facilitate the exchange of experiences between students of all classes and educational faculty-student panels.
A few examples include the M2 Panel on M1 Summer Experiences, during which upperclassmen share their experiences in various summer programs with first-year students, helping them find suitable opportunities. The Research Year Fellowship Panel provides insights into the pros and cons of taking a research year from RWJMS and NJMS students who had either taken a research year or opted not to. The Annual M4 Post-Match Panel features graduating students dissecting the residency application process, current year’s Match statistics, and providing advice on matching into orthopaedics. To introduce students to various sub-specialties in orthopaedics, OSIG invites operative and non-operative physicians along with physical therapists to speak about their career paths, and the benefits and challenges of their field. Our Fall Women In Ortho Panel brings women orthopaedic surgeons from Rutgers and other institutions to campus for a networking dinner with students.
-
Throughout the semester, OSIG hosts a multitude of bioskills workshops, including suture workshops, cadaver and sawbones workshops with companies like Stryker, and b-One splinting/casting labs as well a virtual reality surgical simulation with Osso VR! In Spring 2024, OSIG hosted its inaugural Orthopaedic Trauma Simulation Workshop. Held at the Rutgers Pharmacy School Simulation Lab, the Trauma workshop offered a unique interactive experience where students rotated through four stations, learning about trauma case management, injury anatomy, stabilization and splinting, reading X-rays, and more.
-
To meet the demand for student research projects, our Chair of Research manages a database of current research projects and connects students with academic surgeons at RWJ, NJMS, and Monmouth Medical Center. Our students involved in scholarship are invited to participate in the Department of Orthopaedics Research Update and the Summer Orthopaedics Research Day presentation and poster sessions.
-
Throughout the academic year, OSIG manages a robust shadowing program with weekly OR shadowing opportunities across various subspecialties at RWJUH and SPUH and weekly clinic shadowing spots at RWJUH, SPUH, and RWJ Pediatric Orthopaedics. OR shadowing days allow students to experience a “day in the life of a resident” starting with morning rounds at 5:30 am continuing to education sessions and finally observing surgical cases.
-
OSIG facilitates two summer immersion programs. The RWJ Orthopaedic Summer Immersion program provides RWJMS and outside students with a week-long experience for rising M2s interested in pursuing orthopaedic surgery. During this experience-filled week, two cohorts of students shadow attendings and residents in both clinic and the operating room across various sub-specialties. Program participants attend educational activities such as fracture conferences and grand rounds as well as journal clubs, industry workshops, and networking dinners.
The second formal immersion program is the Orthopaedic Surgery Bootcamp for rising M4 students applying into Orthopaedic Surgery Residency Programs. This week-long session provides students with the necessary skills to succeed in sub-iInternships and away rotations, which are imperative to successfully match in a field like orthopaedics.
-
By regularly participating in OSIG events and orthopaedic shadowing, students can earn a Non-Credit Elective (NCE) notation on their transcript during their preclinical years. To qualify for the NCE, students must attend a total of eight lectures or events throughout their MS1-MS2 years and complete a minimum of 12 shadowing hours through the OSIG shadowing program. This can be done in various settings, including clinics, the OR, on-call shifts, or private physician offices.
Medical Student Rotations
THIRD YEAR MEDICAL STUDENTS
Third year medical students have the opportunity to rotate through orthopedics as part of their surgery rotation. We encourage students to spend additional time with us as fourth year students if they are interested in pursuing an orthopedic residency or have interest in the musculoskeletal system.
During their third year, medical students will have the opportunity to learn the basics of the physical exam of the extremities, observe fracture care in the emergency room, participate in seeing patients in the outpatient clinics, and observe surgery in the operating room. At the end of the rotation, all students should be able to perform a basic musculoskeletal exam, and to be comfortable with the terminology involved in describing fractures as seen on x-ray.
FOURTH YEAR MEDICAL STUDENTS
Fourth year medical students are invited to spend 2-4 weeks working on the orthopedic services at Robert Wood Johnson University Hospital and St. Peter’s University Hospital. Students spend approximately 70% of the rotation in the hospital and 30% in the outpatient offices with full-time and volunteer faculty. Emphasis is placed on physical exam, applied anatomy, and basic clinical decision making. Students have the choice of rotating on the Trauma, Adult Reconstruction, Pediatric, Sports, and Hand services.
Student responsibilities include attending daily morning rounds and all conferences. Active participation in all clinical and operative procedures is encouraged. At the conclusion of the rotation, students will give a 10 minute presentation on an interesting case or germane topic selected by the student. Taking night call to gain a better understanding of resident on-call responsibilities is a required part of the 4th year experience. This opportunity also allows the student to spend one-on-one time with the on call resident. In the past, students performing well during their visiting rotation have been given strong consideration during the residency application process.

Overview
Research is an integral part of each resident's experience at Robert Wood Johnson Medical School. The ACGME requires that each resident produce at least one publishable research project during their 5 years of residency. Currently there are multiple IRB approved clinical prospective and retrospective studies being performed being performed at Robert Wood Johnson University Hospital. All research is driven by the residents with guidance from attending faculty. Residents are required to present their research updates on a quarterly basis to the department, as well as at the RWJ Orthopaedic Research Symposium held at the end of the academic year.
The Orthopaedic Residency Program is also intimately involved with a musculoskeletal biomechanics laboratory chaired by Dr. Dunn located within Robert Wood Johnson University Hospital. This laboratory performs basic science research and provides an opportunity for orthopaedic residents to become involved in tissue engineering as well as the ability to perform animal and cadaveric science research.
For more information regarding ongoing research, or information about becoming involved with orthopaedic research at Robert Wood Johnson Medical School, please contact Dr. Gatt or Barbara Perry.
Orthopaedic Research Laboratory
Our laboratory specializes in the tissue engineering and biomechanics of orthopedic soft tissues including:
- Ligaments and tendons
- Menisci
- Joint surfaces
- Intervertebral disc
Our current projects include:
- Protective treatments to allow for ionizing radiation sterilization of musculoskeletal soft tissue allografts
- Development of a hybrid polymer fiber / collagen sponge for meniscus tissue engineering
- Development of a hybrid scaffold for intervertebral disc tissue engineering
- Understanding of meniscal root mechanics and testing of various fixation methods
Lab Research
Orthopedic injuries are extremely common, especially to the knee. However, the avascular nature of the synovial areas makes it extremely difficult for injured soft tissues to regenerate. Failure to treat these injuries can lead to injury of other soft tissues, leading to cartilage degeneration and improper weight loading. These can cause a patient pain and discomfort, creating a need for tissue engineering of orthopedic tissues. Specifically, we focus on ligament, meniscus, and articular cartilage tissue engineering.
Anterior Cruciate Ligament
Previous work has aimed at creating a scaffold for tissue engineering of the ACL. Material sources include biological (bovine dermal collagen, Bombyx Mori silk) and synthetic (PLLA, poly DTDDD) polymers. Currently, efforts are aimed towards developing an effective radioprotection treatment of tendon allografts to combat the decrease in mechanical integrity following sterilization.
Mensicus
Currently, we are working on a hybrid polymer (poly DTDDD) fiber/collagen sponge scaffold for meniscus TE. Weaving fibers into the pattern to the right can provide sufficient mechanical integrity, both radially and circumferentially, whereas the collagen sponge adds biocompatibility and bioactivity. The polymer degrades over time, giving way to natural tissue, and the collagen sponge is remodeled to form a natural, functional extracellular matrix. Future studies will also experiment with PLLA polymer, as well as partial mensicus implants.
Who We Are
The Orthopaedic Research Laboratory is under the direction of Michael Dunn, PhD, and Charles Gatt Jr, MD. There are currently two graduate students from the Department of Biomedical Engineering at Rutgers University. Additionally, medical students may choose the Orthopaedic Research Laboratory as a site for a four-week research elective. Lastly, we would like to acknowledge the vivarium staff headed by Barbara Perry, and administrative staff headed by Michelle Allen.
In addition to the research done in this lab, many of its members have participated together in extracurricular activities, most notably intramural sports at Rutgers University. These have included volleyball and softball.
