Rosa Knee System

Understanding robotic knee replacement

You’re unique, and so is your individual anatomy. That’s why Columbus Regional Health offers ROSA Robotics technology. ROSA, Robotic Surgical Assistant, is designed to help your specially-trained surgeon tailor the placement of your knee implant just for you.

ROSA Knee is a robotically-assisted surgical system designed to help perform total knee replacement surgery. The system enables surgeons to use computer and software technology to control and move surgical instruments, allowing for greater precision and flexibility during procedures. 

Benefits of Robotic Knee Replacement

  • Increased accuracy compared to traditional knee replacement
  • Better implant positioning, which can result in a more natural-feeling knee after surgery
  • Potential for better long-term satisfaction and outcomes


Healthy joints are covered by a layer of cartilage, which is a tough, lubricating tissue that provides smooth, pain-free motion to your joints. Arthritis,or joint inflammation, can be an extremely painful and difficult condition to manage.

When arthritis develops, the cartilage becomes thinner and eventually wears away down to the bone. This is called osteoarthritis. This type of arthritis results in bone against bone friction. Without cartilage, walking is painful.

Symptoms of osteoarthritis can include:

  • Painful joints, especially after activity or periods of inactivity
  • Joint stiffness
  • Joint swelling
  • Loss of movement in the joint

What is Total Knee Replacement?

The knee joint is one of the largest and most complex joints in the body. It consists of three parts that move and work together to ensure smooth motion and function. The knee is made up of the lower end of the thigh bone (femur), which rotates on the upper end of the shin bone (tibia), and the kneecap (patella), which slides in a groove on the end of the femur. Four large ligaments attached to the femur and the tibia provide stability. Total knee replacement removes the entire surface of the knee joint
and replaces that surface with artificial parts.

What is Partial Knee Replacement?

Often, only one side of the knee is damaged. This is usually the inner side of the knee, but although less common, arthritis can also affect the outer side of the knee. A partial knee replacement, also known as a unicompartmental knee replacement, will replace only the damaged side of the knee, preserving the normal, undamaged cartilage. This may result in a smaller incision, keeping the four natural ligaments and an artificial joint which functions more like the natural knee movement.
