ONS Appoints Joint Replacement Specialist to Head the ONS Outpatient Joint Replacement CenterDr. Berliner

Orthopaedic & Neurosurgery Specialists (ONS) announced today the appointment of orthopedic surgeon and joint replacement specialist, Jonathan Berliner, MD, to the new position of Director of the ONS Outpatient Joint Replacement Center.

Dr. Berliner joined ONS in 2017. He is a fellowship-trained specialist in hip and knee joint replacement and revision surgeries, with an expertise in muscle-sparing anterior hip replacement, minimally invasive total knee and partial knee replacement, complex revision total hip and total knee replacement, computer-assisted surgery, and trauma of the lower extremity.

With a medical degree from the New York University School of Medicine, Dr. Berliner completed his residency in orthopedic surgery at the University of California, San Francisco (UCSF), followed by a fellowship in hip and knee replacement at Hospital for Special Surgery in New York City.

“ONS has been in the forefront of the trend toward outpatient joint procedures,” said ONS Medical Director, James Cunningham, MD. “Dr. Berliner has been an integral part of that effort. Under his leadership, patients can trust ONS to stay ahead of the curve in providing the best research-based options available. “

ONS makes this appointment at a time when the national trend for outpatient joint procedures is growing exponentially.  Currently, more than one million ambulatory joint replacement surgeries are performed annually in the United States.  That number is predicted to jump by 90 percent in the next decade.

At Home Recovery Gains Favor

The movement toward ambulatory joint replacement surgery is fueled by advances in minimally invasive surgical techniques and pain management protocols, and a younger demographic of patients who prefer to recover in the comfort of home.

There are many benefits to outpatient joint replacements versus similar inpatient surgeries as well. Research data indicates that patients have a more comfortable and quicker recovery at home with the support of family and friends.  Patients who recover at home are at reduced risk of infection and newer, long lasting intra-operative anesthetics help to limit the severity of post-operative pain.  The procedure is also less costly, as patients don’t incur charges for tests and services associated with one or two nights in a hospital. ###
