Cori robotic knee replacement
Robotic knee replacement uses a robotic navigation system to help the surgeon place the prosthesis more accurately. This can result in better knee alignment and increased durability of the prosthesis.

Working Mechanism & Indications:
Developed by Smith and Nephew, the CORI system allows surgeons to measure, plan, and perform a knee replacement customized to the patient's unique knee anatomy. It includes a 3D intraoperative imaging system and a robotic sculpting tool. The surgeon uses a handheld cutting instrument that automatically stops when it is outside the marked area. This system does not require CT or preoperative imaging. It is indicated for patients with degenerative knee disease, such as osteoarthritis, that has not responded to conservative treatment.
Preparation & Surgical Procedure:
Preparation for the surgery involves a physical exam, blood work, and imaging. Patients should inform their doctor of any allergies and medications and refrain from eating or drinking for at least 8 hours before the procedure. The surgery is similar to a traditional knee replacement but is performed with the help of the handheld robotic system, which guides the surgeon for greater accuracy in placing the knee implants.
