Physician Assistants & Nurse Practitioners
Our orthopaedic surgeons use a team of midlevel medical providers to assist them in both the clinic and the operating room
In Orthopaedics, Physician Assistants (PAs) and Nurse Practitioners (NPs) are highly utilized both in the clinical setting and in the operating room. PAs and NPs are mid-level medical providers who are nationally certified and state-licensed to practice medicine. In the clinical setting, they are capable of diagnosing and treating a wide variety of orthopaedic conditions, including fracture reductions, joint aspirations, injections, casting, and splinting. In the OR, they serve as first assistants to the orthopaedic surgeon providing valuable assistance during the peri-operative period.
In addition to the help they provide our Orthopaedics team in the office, all of our Physician Assistants and Nurse Practitioners support Dr. Matthew Griffith's community outreach by helping him cover home football games at Potomac Falls High School and Park View High School.
Studies have identified high-quality care with physician-PA/NP teams and have shown that the quality of care provided by PAs and NPs is comparable to that of physicians, that PAs and NPs enhance care coordination, and that PAs and NPs are proven to elevate health outcomes and increase patient satisfaction.
