“HSS has led the fields of orthopedics and rheumatology in quality and patient experience for 161 years,” said HSS President and CEO Bryan T. Kelly, MD, MBA. “The HSS Northern NJ Surgery Center in Mahwah and HSS Paramus – Midland Ave are more than just facilities—they're purpose-built extensions of the main hospital, offering the same sophisticated, highly specialized care but in a more accessible location. They reflect our commitment to serving communities by expanding care through innovation and strategic growth across the tri-state region and beyond.”

The HSS Northern NJ Surgery Center is a 7,700-square-foot facility conveniently located at 400 Franklin Turnpike, just 10 miles away from HSS Paramus – Midland Ave. The center features three operating rooms, eight pre- and post-surgical bays and on-site central sterile processing.

The Mahwah surgery center will focus on specialized care for conditions and injuries of the hip and knee, spine, foot and ankle, hand and wrist, as well as sports medicine surgery. Michael P. Ast, MD, chief of the Knee Service, Chief Medical Innovation Officer and Director of Ambulatory Surgery Center Strategy at HSS, serves as the Medical Director.

“With the advanced technologies we’ve implemented at our ambulatory surgery center, we’re now able to safely perform a wider range of complex procedures that were once only possible in a hospital setting,” said Dr. Ast. “By expanding access in New Jersey, more patients can receive timely outpatient procedures, reducing wait times, hospital burdens, and the need to travel into New York City. At the same time, our new center is fully integrated with our main hospital, ensuring patients benefit from the same world-class diagnosis and treatment options.”

HSS Paramus – Midland Ave, located at 15 E. Midland Ave, Suite 1A, features 23 exam rooms and highly specialized physicians and staff to offer care for conditions and injuries of the foot and ankle, hand and upper extremities, hip and knee, and spine; endocrinology/metabolic bone diseases; pediatric orthopedics; physiatry; rheumatology; and sports medicine.

The nearly 31,000-square-foot facility is double the size of the existing OPC, HSS Paramus – Ridgewood Ave, allowing for an expansion of services and a state-of-the-art imaging suite including MRI, x-ray, and EOS low-dose radiation imaging. A special procedures unit for injection therapy and other advanced interventions is also available at this site. Additionally, HSS Orthopedics Now, providing quicker access to orthopedic care for sudden injuries and pain for patients 12 years and older, is available.

“I am deeply honored to lead HSS Paramus into its next chapter,” said Anil S. Ranawat, MD, sports medicine surgeon at HSS and medical director of HSS Paramus – Midland Ave. “This new facility is an exciting milestone in our unending pursuit to make comprehensive care even more accessible, enabling patients to complete their entire care journey—including testing, surgery, and more—right here in New Jersey.”

The new sites join the existing HSS location in Paramus on East Ridgewood Avenue. For more information about HSS Paramus-Midland Ave and HSS Northern NJ Surgery Center, visit www.hss.edu/locations.
