Berliner, MD
Hip & Knee Replacement · Assistant Professor of Orthopedic Surgery
Anterior approach hip replacement and robotic-arm assisted knee replacement, in the Bronx.
Hips and knees done with modern cutting-edge techniques
The anterior approach reaches the hip through the natural gap between two muscle groups, leaving the muscles at the back of the joint attached. Most patients walk within hours of surgery.
Robotic-arm assisted knee replacement
Your knee is mapped in three dimensions before any bone is cut. The robotic arm holds the cutting tool inside the plan the surgeon sets, and the plan is built from your own alignment.
Specialized in arthroplasty
Fellowship training in adult reconstruction at the Hospital of the University of Pennsylvania, completed in 2024, following an orthopedic surgery residency at Boston Medical Center.
Hip & Knee Care
Conditions and procedures
Hip arthritis
Groin pain and stiffness that limits stairs, socks, and getting out of a car.
Knee arthritis
Pain on stairs and walking, swelling, and a knee that gives way or locks.
Total hip replacement
Anterior approach where anatomy allows. Surgery takes one to two hours.
Total knee replacement
Robotic-arm assisted, planned from your alignment before the first cut.
Partial knee replacement
Resurfaces one of the knee's three compartments and preserves the other two.
Revision hip and knee
A prior replacement that has become painful, loose, or worn.
Avascular necrosis
Loss of blood supply to the femoral head, which damages the hip in younger adults.
Second opinions
Bring your imaging and any operative report for review before you decide.

Before You Call
Common questions
Do I need a referral to be seen?
That depends on your plan. Many plans allow you to book a specialist directly. HMO plans usually require a referral from your primary care doctor first. Call the number on the back of your insurance card to confirm before you schedule.
What happens at the first visit?
The visit takes about 30 minutes. Your hip or knee is examined, X-rays are taken the same day, and you review the images together. You leave knowing which parts of the joint are worn and which treatments apply. Most first visits do not end in scheduling surgery.
Will I be told I need surgery?
Not at a first visit, in most cases. Joint replacement treats arthritis pain that limits daily activity after non-surgical care has stopped working. Activity changes, physical therapy, anti-inflammatory medication, and injections come first.
Which insurance plans are accepted?
Accepted plans include 1199SEIU Benefit Funds, Aetna, Anthem Blue Cross Blue Shield, Affinity by Molina Healthcare, and Amida Care. Plan participation changes, so confirm your specific plan with the office at 718.920.2060 before your visit.
Where would I be seen?
Seven offices across the Bronx, New Rochelle, and Mount Vernon. The main office is 1250 Waters Place in the Bronx. Tell the scheduler which area you are traveling from and they will book the closest office.
Can I get a second opinion?
Yes. Bring your X-rays, any MRI, and the operative report if you have had prior surgery. A second review either confirms the recommendation or identifies a non-surgical option worth trying first.
