Joint Replacement Program

The expertise you need to succeed

For individuals with chronic pain and limitations due to arthritis or irreversible joint damage to the knees, hips, or shoulders, joint replacement is often the best course of action. If you and your specialist decide this is your best way forward, you can rest assured our program is second to none. Our expert team performs hundreds of joint replacement procedures every year, using the latest and most advanced prosthetics for lasting, reliable outcomes. For added peace of mind, our dedicated nurse navigator will guide you every step of the way, before, during and after surgery.

Advanced devices and procedures

Robotic-assisted knee replacement

We’ve invested in the ROSA® robotic surgical assistant to help our surgeons tailor their knee replacement surgery to each patient. This system ensures that the implant is precisely placed in line with the patient's unique anatomy, resulting in better outcomes. It’s also minimally invasive so patients can recover faster. Note: for some patients, this procedure may not be suitable.

Ultrasound-guided hand procedures 

Our fellowship-trained hand specialist offers the latest treatments for painful and debilitating hand conditions. Our UltraGuideCTR™ system for minimally invasive carpal tunnel release provides better visualization of the hand anatomy and shorter recovery times. All procedures are conveniently offered at our medical office in Sonora.
