Enjoy life pain free.
Leave knee and hip pain behind.

CMH surgeons are now the only orthopedic specialists in the region who perform hip and knee replacements using a state-of-the-art robotic surgical system that is far more precise than conventional surgery. Using computer modeling, a robotic instrument and the patient’s CT images, CMH surgeons plan and perform surgeries with a degree of accuracy that’s unavailable anywhere else in the region.

Precision robotic joint replacement surgery at CMH means:

  • Better balanced, more natural feeling joints
  • Significant reduction or elimination of chronic joint pain
  • Shorter post-surgical hospitalization
  • A quicker return to a more active life
  • A comprehensive and caring patient experience in a modern, private room with stunning views of the Catskills and Hudson River


At Columbia Memorial Hospital, we know that an informed decision is a decision well made. We’ve compiled many short informative videos that you can play at your leisure to learn more about joint replacement, and how CMH can help you on this journey.
