Orthopaedic Surgery Center

The Orthopaedic Surgery Center (OSC) has two locations: one in Concord and a second in Derry.
Both, ambulatory (“day”) surgery centers provide surgical and spinal injection procedures.

OSC/Concord opened its doors in February 1995.It has three operating rooms, a pre-operative area and a post-operative recovery area.

OSC/Derry opened in January 2012.This surgery center has two operating rooms, a pre-operative area and a post-operative recovery area.


The Orthopaedic Surgery Center is a collaborative effort between the physicians of Concord Orthopaedics and Concord Hospital. The physicians of Concord Orthopaedics work with anesthesiologists, nurses, and operating room and recovery staff to ensure patient safety and excellence in care.

Day surgery centers are designed for patients who are ambulatory (able to walk and not confined to a bed). Surgical procedures performed allow patients to undergo a procedure and return home the same day. At the OSC, we know surgery in any format can be unnerving and that is why we strive to create an atmosphere that is convenient, safe and friendly.

Some of the more common procedures we perform are: arthroscopy and open procedures of the knee, shoulder, ankle and elbow, fracture and tendon repairs, foot surgery, Achilles tendon repair, rotator cuff surgery and hand surgery including carpal tunnel release and trigger finger surgery.

The Orthopaedic Surgery Center is committed to providing the highest standard of orthopaedic surgical care and spinal injection procedures in a professional, compassionate and considerate manner specific to the individual needs of our patients. We are certified by the Center for Medicare and Medicaid Services ("CMS").

To our Patients, Families and Communities,

Your health, welfare & safety are paramount when you come for an appointment at any of our facilities. We are closely monitoring the guidance of the World Health Organization and the Centers for Disease Control & Prevention regarding the spread of the virus. Our focus is to ensure we meet our patient’s needs while doing our part to keep you, our associates, and our communities safe. Effective immediately, the Acute Injury Clinic (AIC), will remain open Monday-Friday from 9 a.m. - 4 p.m. The AIC will NOT open on Saturdays.

At this time, the impact to our communities has been minimal and our staff is focused on providing the orthopaedic care our patients expect and deserve. If you have an appointment with us, we respectfully ask that you let us know if you have a fever, cough, and/or shortness of breath in advance of your appointment. Also, if you have recently traveled to or been in close contact with anyone who has traveled outside of New Hampshire, especially to New York State, we ask that you avoid visiting our practice for a period of 14 healthy days.

Thank you for your continued trust in COPA. We appreciate your cooperation as we work to support the health of our patients & employees.
