Intended Use

The Partial Knee Application (PKA), for use with the Mako System, is intended to assist the surgeon in providing software defined spatial boundaries for orientation and reference information to anatomical structures during orthopedic procedures. The Partial Knee Application (PKA), for use with the Mako System, is indicated for use in surgical knee procedures in which the use of stereotactic surgery may be appropriate, and where reference to rigid anatomical bony structures can be identified relative to a CT based model of the anatomy. These procedures include unicondylar knee replacement and/or patellofemoral knee replacement. The Implant systems with which the system is compatible: • Restoris Multicompartmental Knee System

Device Story

Mako System with Partial Knee Application (PKA) is a stereotactic instrument for orthopedic surgery; includes robotic arm, integrated cutting system, optical detector, computer, and planning laptop. System uses patient CT data for pre-surgical planning and intraoperative navigation. Robotic arm acts as intelligent tool guide; provides haptic guidance by passively constraining bone preparation within software-defined spatial boundaries. Used in OR by surgeons to assist in implant placement. Output consists of visual navigation and haptic feedback to ensure accurate resection. Benefits include improved surgical precision and implant alignment.

Clinical Evidence

Bench testing only. Performance evaluated via sub-system software functional testing, implant visual/boundary/stereotactic verification, resection accuracy verification, full system mock procedure run-throughs, and full system cadaver validation.

Technological Characteristics

Stereotactic instrument; robotic arm; optical detector; CT-based imaging; software-defined spatial boundaries; haptic guidance. Components: Guidance Module, robotic arm, camera stand, cutting system, planning laptop. Reusable and disposable instruments. Software-controlled passive constraint system.

Indications for Use

Indicated for surgical knee procedures (unicondylar or patellofemoral knee replacement) where stereotactic surgery is appropriate and rigid anatomical bony structures can be identified relative to a CT-based model.

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.

### Description:

The Mako System with the Partial Knee Application is a stereotactic instrument that includes a robotic arm, an integrated cutting system, an optical detector, a computer, dedicated instrumentation, operating software, a planning laptop, and tools and accessories.

The system's architecture is designed to support total and partial knee procedures and total hip procedures. With application specific hardware and software, the system provides stereotactic/haptic guidance during orthopedic surgical procedures by using patient CT data to assist a surgeon with pre-surgical planning, implant placement and interpretive/intraoperative navigation of the patient's anatomy.

The Mako robotic arm, once configured for a specific application, can serve as surgeon's "intelligent" tool holder or tool guide by passively constraining the preparation of an anatomical site for an orthopedic implant with software-defined spatial boundaries.
