## Indications for 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
