Leading the Way in Ankle Arthritis Care

Total ankle replacement is not a common procedure. Only several hundred procedures are performed every year in the United States, and you may never meet another person who has gone through it. While this can be scary and intimidating, it doesn’t have to be.

At HSS, we have a team of doctors, nurses, and physical therapists who have extensive experience in ankle replacement. As the No. 1 hospital for orthopedic surgery, thousands of patients travel here worldwide to seek our expertise and our commitment to providing our patients with the best outcome possible. Not only are our specialists at the top in their fields, but they are also at the forefront of research, education, and the latest techniques.

Individualized Care for Every Patient

When you come to HSS, you may not realize you require an ankle replacement. Many have debilitating ankle arthritis and pain that has gone unchecked or ignored. Others are coming for a second opinion or a solution to chronic ankle pain. We ensure that the first step is a thorough assessment of the ankle and the foot. Together, we then formulate a plan to address the arthritis in your ankle, and to correct any deformity or malalignment that may also be existing. 

To help you through the process, we often connect you with a patient who has gone through total ankle replacement, so you can have a firsthand account. Watch our video featuring an HSS patient who suffered multiple injuries to her ankle that led to severe arthritis.

Ankle Researchers

Top Ankle Surgeons and Specialists

HSS Foot and Ankle Surgeons are the top specialists in treating ankle arthritis and the issues that lead to ankle replacement surgery. We see a high number of complex cases from around the country and perform more ankle replacements than any other hospital in the New York City Tri-state area. Our reputation in education and research increases our ability to collaborate with specialists around the world and provide patients with the best options.

Know that everyone from the radiologist who performs your imaging test to your physical therapists after surgery is specialized in ankle injuries and has extensive experience in your procedure.


State-of-the-Art Imaging Technology

Accurate, personalized imaging from a highly specialized radiology team is at the core of our Total Ankle Replacement Center. A dedicated series of images (X-ray, CT Scan, MRI) are needed for preoperative surgical planning, as well as to track your progress after surgery. Weightbearing CT scans with lower radiation levels provide a 3D model of the ankle mimicking real life positions and uses. Our industry-leading, high-resolution MRI is powerful enough to visualize the smallest structures of the foot and ankle, and adaptable enough to track every phase of your recovery.
