ORTHOPEDICS | Computer Assisted Surgery | Evergreen Orthopedic Research Lab
Evergreen Orthopedic Research Lab
Evergreen Hospital is one of only a handful of places on the West Coast doing minimally invasive MIS), compuer-assisted (CAS) knee replacements on all of its patients. A big reason why is the Evergreen Orthopedic Research Lab.
The Lab is home to a collaborative effort among orthopedic surgeons, hospital staff and research technicians devoted to advancing MIS and CAS. The Lab designs new surgical instrumentation, tests MIS and CAS techniques in cadaver models and develops data for use in the operating room.
The Lab has been developing its own MIS techniques since the late 1990s, and has designed its own unique CAS instruments for the smaller, minimally invasive incisions.
The orthpedic surgeons pioneering computer-assisted joint replacement use a 3D computer imaging system that allows them to see the unique anatomy and mechanics of each patient's joint, make precise surgical cuts and review alignment and range of motion with the implant in place before leaving the OR.
What are the advantages of computer-assisted surgery? Traditional surgery depended on the surgeon's eye, which allowed them to usually get within five degrees of the optimal alignment of the new joint. The CAS technique provides more precise information about where to make the cuts. The surgeon places pins in the femur and tibia to hold a wireless transmitter. A transceiver in the OR picks up the infrared spectrum, and the surgeon is able to take the knee through a range of motion while the computer calculates flexion and extension, joint gaps and other data.
The result is a better aligned knee, and a joint replacement that will be longer lasting.
