Meet with Our Team of Orthopedic Specialists


At Ascension Saint Agnes, our experienced orthopedic specialists use the latest imaging technologies and surgical techniques. Many of our patients report a higher level of function and better pain control. 

Ask about virtual care (e.g, telehealth or online) appointments for your first consultation and as part of your ongoing care. You can have these virtual visits from the comfort of your home. You’ll be able to talk with your doctor one on one via video from your phone or computer and get the care that’s right for you.

Before your appointment, you should check with your insurance company to find out if a second opinion is covered or required. Ascension Saint Agnes can request your medical records from your doctor on your behalf so that they can be shared with your care team before your arrival.

It’s Time for You to Consider
Joint Replacement Surgery

Shoulder, knee and hip pain can keep you from the simple things in life, such as climbing the stairs, walking outdoors on a beautiful day, or spending time with family and friends. Keeping up with daily tasks can be difficult when you have joint pain that stops you from moving.

If your joint pain is affecting your daily life, it may be time to think about shoulder, knee or hip replacement surgery.

Does your joint pain:

  • Keep you awake at night?
  • Cause you to limp when you walk?
  • Make you feel stiff and swollen?
  • Cause you to fall? How often?

If yes, joint replacement surgery may be right for you.
