Total Knee Replacement / Arthroplasty

​

Approximately 700,000 knee replacement procedures are performed annually in the US. This number is projected to increase to 3.48 million procedures per year by 2030.

​

Total knee replacement, or total knee arthroplasty, is a surgical procedure in which parts of the knee joint are replaced with artificial parts (prostheses).

​

A normal knee functions as a hinge joint between the upper leg bone (femur) and the lower leg bones (tibia and fibula). The surfaces where these bones meet can become worn out over time, often due to arthritis or other conditions, which can cause pain and swelling.

​

Knee replacement is one option to relieve pain and to restore function to an arthritic knee. The most common reason for knee replacement is that other treatments (weight loss, exercise/physical therapy, medicines, and injections) have failed to relieve arthritis-associated knee pain.

​

The DRAS Knee Balancing System can be used during the operation to help the surgeon align the implant and leg in real time for the best possible post-surgery results.

 

The DRAS sensor, a paper-thin film, is placed in the knee to track the center of force, the contact area and the amount of force. The sensor data is collected by the DRAS Handle and visualized on the computer in real time.
