ROSA® Knee Replacement Technology

Advanced Robotic-Assisted Knee Replacement, Close to Home

When knee pain keeps you from doing the things you love, you deserve access to advanced treatment options close to where you live. MercyOne is proud to offer ROSA® Knee System technology, an innovative robotic-assisted tool designed to help our orthopedic surgeons plan and perform personalized knee replacement procedures. ROSA combines advanced technology with the expertise of your MercyOne orthopedic surgeon to support greater precision throughout surgery, helping patients take the next step toward improved mobility and quality of life. Because every knee is unique, every knee replacement should be, too.

ROSA stands for Robotic Surgical Assistant. It is designed to assist orthopedic surgeons during total knee replacement procedures. 

Before and during surgery, the ROSA system collects detailed information about your knee, helping your surgeon create a personalized surgical plan based on your unique anatomy. 

Throughout the procedure, ROSA provides real-time data to help surgeons accurately position and align knee implants while remaining fully in control of every surgical decision. 

ROSA does not perform surgery on its own. It is a sophisticated tool that enhances the expertise and experience of your orthopedic surgeon.

Our orthopedic team provides comprehensive care before, during and after surgery, helping patients return to the activities they enjoy with confidence.

Patients may benefit from:

  • Smaller incisions: The procedure requires less cutting of skin and muscles, leading to less visible scarring.
  • Tissue preservation: Using real-time tracking and surgical data, ROSA assists surgeons in preserving healthy muscles, ligaments, nerves and surrounding tissue during the procedure, helping support the natural movement of your knee.
  • Reduced blood loss: Because the procedure is designed to be precise and targeted, patients may experience less blood loss compared to traditional surgical approaches.
  • Less pain during recovery: By minimizing trauma to the knee and surrounding tissues, many patients experience less post-operative discomfort, which may reduce the need for pain medication after surgery.
  • Faster rehabilitation: Patients generally regain mobility, rebuild strength and return to the activities they enjoy sooner.
  • Shorter hospital stays: Many patients are able to return home the same day or within 24 hours after surgery, allowing them to begin recovery in the comfort of their own home.

Every patient is different. Your orthopedic surgeon will discuss whether robotic-assisted knee replacement is right for you.

ROSA-assisted knee replacement may be an option for patients experiencing:

  • Osteoarthritis
  • Rheumatoid arthritis
  • Post-traumatic arthritis
  • Chronic knee pain
  • Reduced mobility
  • Knee joint damage that has not responded to conservative treatments
