How Does a Knee Work?

Robotic-Assisted Knee Replacements

Combined with the expertise and experience of orthopedic surgeons Dr. Dirk Gouge and Dr. Thomas Herschmiller, the CORI surgical system allows the surgeons to make more accurate cuts, leading to more even soft tissue balance and, ultimately, better patient outcomes in the form of less pain and increased range of motion.

The following information is provided by Smith+Nephew, the company that produces the CORI robotics system.

Anatomy and function of the knee

What makes up your knee?

The knee joint is the point at which the femur bone of the thigh meets the tibia bone of the lower leg. All the components of the knee - bones, cartilage, synovial membrane, ligaments, tendons and muscles - must work together properly for the knee to move smoothly.

Cartilage is a protective cushioning that keeps the bones from rubbing against one another.

In a healthy knee, a thin, smooth tissue liner called the synovial membrane releases a fluid that lubricates the knee, reducing friction as the bones move.
