Mako Integrated Cutting System (MICS) Handpiece, Catalog Number 209063, Software Version#: THA 3.0 and later, PKA 3.0 and later, and TKA 1.0 - Product Usage: The MICS Handpiece is attached to the distal end of the robotic arm and is used to register the RIO (Mako robot) and to execute bone preparation during a Mako Total Knee or Mako Partial Knee procedure (PKA Software Application 3.0 or later).

Stryker has discovered a characterization issue associated with the Mako Integrated Cutting System (MICS) Handpiece. The MICS Handpiece is attached to the distal end of the robotic arm and is used to register the RIO and to execute bone preparation during a Mako Total Knee or Mako Partial Knee procedure (PKA Software Application 3.0 or later). This issue may result in unsuccessful checkpoint verification when the Mako System attempts to verify the location of the saw blade prior to bone preparation. This issue may also cause a discrepancy during bone preparation in a Mako Total Knee or a Mako Partial Knee procedure in which the surgeon uses a straight or angled saw attachment with the MICS Handpiece. The surgeon may make cuts during bone preparation that differ from the surgeon s preoperative plan.
