Staff at Orthoparc in the Netherlands have developed a method of patient-centered total knee replacement through Surgical Guides that helps make the surgery less invasive, removing the need to drill into the femur canal as in traditional knee replacement surgery procedures and simultaneously increase the comfort of patient. These surgical guides are produced using data gathered about an individual patient’s knee and are fabricated in-house on a 3D printer. When placed upon the patient during surgery, they guide the surgeon to exactly where cuts need to be made in relationship to where the knee is resting.
