Indications for Use
The PiGalileo™ TKR System is intended to be used in computer-assisted orthopedic surgery to aid the surgeon with bone cuts and implant positioning during joint replacement. It provides information to the surgeon that is utilized to place surgical instruments during surgery utilizing anatomical landmarks and other data specifically obtained intra-operatively (e.g., ligament tension, limb alignment, etc.). Examples of some surgical procedures include but are not limited to: - Total knee replacement supporting both bone referencing and ligament balancing techniques - Minimally invasive total knee replacement
Device Story
PiGalileo™ TKR System is a software-controlled electromechanical stereotaxic device for computer-assisted orthopedic surgery. It tracks surgical instruments in real-time using infrared (IF) LED or passive markers attached to the tibia and distal femur. An IF camera captures positional data intra-operatively to establish anatomical landmarks. The system processes this data to guide the surgeon in positioning prostheses and motorized cutting guides. Used in the OR by surgeons; the system provides real-time navigation information on a monitor. The surgeon maintains full control, with the ability to adjust guides manually or convert to conventional non-navigated techniques. Benefits include optimized implant positioning and support for minimally invasive procedures.
Clinical Evidence
No clinical data was assessed. The device's substantial equivalence was established through design verification and validation bench testing conducted in accordance with FDA Design Control Requirements (21 CFR 820.30).
Technological Characteristics
Stereotaxic navigation system using infrared (IF) camera and passive markers. Components include system cart, electronics, monitor, user interface, and surgical instruments. Complies with IEC 60601-1-2 (EMC), IEC 60601-1-4 (software safety), and UL 60601-1 (electrical/mechanical safety). Biocompatibility of surgical tools per ASTM/ISO standards. Software-controlled electromechanical operation.
Indications for Use
Indicated for patients undergoing computer-assisted orthopedic surgery, specifically total knee replacement, including bone referencing, ligament balancing, and minimally invasive techniques.
Regulatory Classification
Identification
A stereotaxic instrument is a device consisting of a rigid frame with a calibrated guide mechanism for precisely positioning probes or other devices within a patient's brain, spinal cord, or other part of the nervous system.

### E.4 Device Description
The PiGalileo™ Navigation (NAV) Total Knee Replacement (TKR) Computer Assisted Surgical (CAS) System (PiGalileo™ TKR System) is a softwarecontrolled electromechanical sterotaxic device for computer-aided navigation of PI Galileo surgical instruments with the purpose of assisting the surgeon in optimally positioning prostheses of the TC-PLUS and VKS knee systems.

{1}------------------------------------------------
The PiGalileo™ TKR System is based on common stereotaxic technology in which Infrared (IF) LED (light emitting diodes) or passive markers on the surgical instruments allow the instruments to be tracked in real time in the surgical field.
In the case of PiGalileo™ TKR System, patient data that is required to navigate the surgical instruments is collected during the procedure. The system utilizes this data to establish a connection between passive locaters, i.e., Infrared (IF) light, and the system's IF camera as previously described tracks the surgical instruments in real time in the surgical field.
Two passive locators are attached to the tibia and distal femur during surgery, where one locater is mobile to determine specific landmarks, known as Bone Referencing (BR) on the tibia and femur. Once the system has collected the information, the system positions a motorized cutting guide on the femur to support the surgeon during surgery and provides information to position or "navigate" additional instruments.
The surgeon maintains control of the operation and any decisions required with regard to the surgery at all times. Positions of the motorized cutting guide may also be adjusted manually. Risk mitigations were implemented under Design Controls to ensure that sufficient fail safe mechanisms allow the surgeon to convert to non-navigated conventional surgical techniques at any time.
The PiGalileo™ TKR System consists of three main elements:
- System Cart which houses: 4.1
