Not all hospitals achieve the same results

Knee replacement is a surgery focused on reducing pain and getting you back to the activities you love. But not all hospitals achieve the same results. Some are more reliable than others. With the help of the HSS Hospital Reliability Scorecard, you can make sure you're asking the critical questions to find the hospital that's right for you. Understanding the data points below will help you make the best decision for your care. Learn why we chose these factors.

Partial Knee Replacement Overview

What

A knee replacement surgery that replaces only one compartment of the knee (either the medial or lateral) with implants, while preserving the healthy tissue of the other compartments. Also known as "unicondylar knee replacement."

Where

Takes place in a hospital or ambulatory surgery center.

Length of hospital stay

Less than one day in the vast majority of cases, however, it can extend to an overnight stay depending on your overall health and access to caregiver support at home.

Testimonial

Brian, HSS Patient

On the one-year anniversary of my surgery, I ran 10 miles. I have no pain at all and feel like I did 15 years ago. Go to the hospital that's ranked #1 in orthopedics and get you back to doing everything you want do.
