New leadership, new faculty, and advances in clinical care have made for a busy year at Columbia’s Division of Hip & Knee Reconstruction in the department of Orthopedic Surgery.

Under the leadership of division chief Jeffrey A. Geller, MD, Nas S. Eftekhar Professor of Orthopedic Surgery, and with the addition of H. John Cooper, MD, to current faculty Ohannes A. Nercessian, MD, and Roshan P. Shah, MD, the division remains committed to leveraging the full array of modern treatment options while maintaining the highest standards throughout each patient’s entire episode of care.

Newly appointed division chief Jeffrey A. Geller, MD, is the Nas S. Eftekhar Professor of Orthopedic Surgery.

“I’m proud to lead this group of outstanding surgeons who are helping to redefine state-of-the-art care for hip and knee patients,” said Dr. Geller, an internationally recognized leader in partial knee replacements, minimally invasive total knee replacements, and the newest techniques in anterior hip replacements.

“Once we have exhausted nonoperative treatment options, our team builds surgical plans tailored to the specific goals and needs of each patient – all leading toward our ultimate goal of speeding recovery, minimizing pain, and restoring mobility.”

John Cooper, MD, assistant professor of orthopedic surgery, joined the Columbia team in January after migrating a thriving practice from Lenox Hill Hospital.

“One of the most pleasant aspects of my transition to Columbia has been the ability to work as part of the ColumbiaDoctors team, and offer the full spectrum of specialty care to all of my patients. I continue to be amazed by the degree of professionalism and shared dedication to excellent patient care that my new colleagues bring to work every day,” Cooper said.

“My goal is to build upon the excellent established track record in hip and knee arthroplasty by leveraging the latest technology and techniques to provide superior clinical outcomes for patients.”

Ohannes Nercessian, MD, associate professor of orthopedic surgery, has decades of experience managing complex surgical hip and knee reconstructions. Known for his expertise in bone grafting techniques to restore bone loss, and surgical treatment of osteoporosis-related hip fractures, Dr. Nercessian trained at NYP/Columbia with two of the earliest pioneers in joint replacement surgery, Drs. Frank Stinchfield and Nas Eftekhar.

Roshan P. Shah, MD, assistant professor of orthopedic surgery, is now in his fourth year of practice at Columbia and has made a name for himself as an innovator in the field. In addition to expertise in minimally invasive anterior hip arthroplasty, Dr. Shah has a particular interest in advanced knee reconstruction techniques.

“For knee replacement patients, I use a method that does not require forceful dislocations of the knee used in traditional approaches. In some cases, I judiciously use a custom knee replacement forged individually and precisely for specific patients,” he said. Based on a CT scan reconstruction of their particular anatomy, these custom devices come with 3D printed surgical tools that also match the specific patient perfectly, Shah said. “The ultimate goal of both approaches is faster recovery with less pain.”
