3. Description
3.1 Overview The ROSA Knee System is a robotic platform that aims at assisting orthopedic surgeons with the bony resections as well as assessing the state of the soft-tissues to facilitate implant positioning during a total knee arthroplasty. Surgical planning software can be used pre-operatively by the surgeon to plan implant positioning and sizing. The surgeon may also use the imageless option within the ROSA Knee System to achieve the same goal as an image-based case. The device is composed of two units, one positioned on each side of the operating table: • A Robotic Unit consisting of a compact Robotic Arm and a Touchscreen • An Optical Unit and a Touchscreen The intra-operative workflow and surgical concepts implemented in the system remain close to the conventional TKA workflow. As such, at the time of the surgery and based on the surgical plan, the system mainly assists the surgeon for: • Determining reference alignment axes in relation to anatomical landmarks • Planning the orthopedic implants location based on these reference alignment axes and orthopedic implant geometry • Assisting in joint balancing • Precisely positioning the Cut Guide relative to the planned orthopedic implant location by using a Robotic Arm Optical Camera Robotic Arm Touchscreen

3.2 Operating Principle The operating principle for a total knee arthroplasty procedure is described below. 3.2.1 Case Information The case is launched with a USB drive plugged to the Robotic Unit using the case management application. The welcome screen of the software confirms the patient ID, procedure laterality, implant family and instrumentation. Once the user has confirmed the information, the ROSA Knee Software can be launched. 3.2.2 Pre-operative Planning Image-based cases The patient’s knee, reconstructed in 3D using pre-operative X-rays or MRI, can be used pre-operatively by the surgeon to plan the surgery. In this case, a 3D bone model will be displayed in some panels. If the registration of the landmarks taken intra-operatively and the patient knee reconstructed in 3D is unsuccessful, the user will have the possibility to redo the landmarks, or switch to an imageless case. Imageless cases If desired, the surgeon can decide not to plan the surgery prior to the surgery date, and use the ROSA Knee System directly intra-operatively. In this case, generic bone schematics will be displayed in the user interface. If a Persona IQ implant is used, please refer to the Persona IQ Surgical Technique in the Pre-operative Planning section. 3.2.3 OR Setup The patient is placed on the surgical table in supine position. The Robotic Unit is positioned approximately at the patient’s hip and approximately 45° relative to the surgery table. Two patient bone references are installed on the patient’s femur and tibia as a reference for leg movements. A third reference is located on the Robotic Unit (on the post of the ROSA Base Reference Bar closest to the surgical table), to track where the Robotic Unit is relative to the patient’s leg during the surgery. During the surgery, the surgeon must always stay on the same side as the Robotic Unit. The maximum height of the patient on the OR table should be 44 inches to minimize tracker visibility problems. In case of a patient with a high BMI, lower the table to avoid visibility problems. There are four possible OR setups: • Operating a right knee, with the surgeon on the same side as the operated knee • Operating a right knee, with the surgeon on the opposite side of the operated knee • Operating a left knee, with the surgeon on the same side as the operated knee • Operating a left knee, with the surgeon on the opposite side of the operated knee

3.2.4 Robotic Unit Registration A registration of the Robotic Unit is performed with a fourth reference mounted on the Robotic Arm prior to the start of the surgery. This ensures the functional verification of the Robotic Arm prior to the start of the surgery. The patient should be in the OR for this step.

3.2.4 Robotic Unit Registration (cont.) Risks of collision: When the Robotic Unit is in Automatic mode, stay clear of the Robotic Arm and its path to the next position. 3.2.5 Bony Landmarks & Navigation Using a registration pointer, the surgeon will digitize the bony landmarks to record the patient leg coordinate system (HKA alignment). Throughout the surgery, real-time tracking of patient movements is provided by the optical tracking system. 3.2.6 Planning If not done pre-operatively, the surgeon can set his surgical plan intra-operatively, i.e. the femur and tibia bone cuts according to preferences and the chosen implant components. If a Persona IQ implant is used, please refer to the Persona IQ Surgical Technique in the Pre-operative Planning and Sizing and Drilling of Tibia sections. 3.2.7 Surgery Based on the intra-operative planning values, the Robotic Arm will move to reach the appropriate positions to execute the bone resections. Risks of collision: When the Robotic Unit is in Automatic mode, stay clear of the Robotic Arm and its path to the next position. If the Femoral Rotation Assessment (optional) is selected, the ROSA Knee System provides clinical information to assist the surgeon in setting up the femoral rotation, taking into consideration the condition of the knee (medial and lateral gaps, as well as ligament laxity).
3.3 System Description 3.3.1 Robotic Unit The Robotic Unit is composed of the following main components: • The Robotic Arm • The Touchscreen for operating the device • The immobilization system • The Foot Pedal • The computer and software The Robotic Unit is equipped with swivel wheels and handles allowing the device to be easily moved from one operating room to the other by a single person.
