Description
Mako RPS (Robotic Power System) is a robotically enabled handheld cutting system designed to support surgeons during total knee arthroplasty with real‑time intraoperative registration and guidance. The device provides a handheld workflow that does not require preoperative imaging and is intended to assist in bone preparation, implant positioning and alignment assessment throughout the procedure.

Key features

• No preoperative imaging required
• No cutting blocks
• Handheld design optimized for the operating room
• Patented active adjustment technology that responds to the surgeon’s hand movements to maintain alignment with the surgical plan
• Tibial boundary control: resection is disabled when the handpiece reaches the surgeon‑defined posterior protection boundary
• Real‑time intraoperative registration and guidance to support implant planning, alignment assessment and bone resection
• Integrates with Stryker’s Q Guidance System and multi‑specialty guidance platforms
• Supports planning and intraoperative adjustments for the Triathlon Total Knee system
• Supports both gap balancing and measured resection workflows

Mako RPS for Total Knee workflow
The Mako RPS Total Knee workflow uses intraoperative registration and guidance to enable the surgeon to evaluate limb alignment, visualize soft tissue balance data and plan implant positioning before performing guided resections. After tracker fixation and anatomy registration, the system supports iterative planning, guided bone preparation and final alignment verification prior to implantation.

Workflow steps

• Step 1: Anatomy registration
  • The surgeon registers points on the femur and tibia to define patient anatomy.
  • During registration the surgeon selects a tibial boundary point used to generate a plane that disables resection if crossed, protecting posterior structures.
• Step 2: Pose capture and implant planning
  • Capture flexion and extension poses in the desired alignment and laxity for the final implant positions.
  • Plan implant position and adjust for the Triathlon Total Knee system.
  • Choose between gap balancing and measured resection workflows as clinically indicated.
• Step 3: Bone resection
  • Mako RPS active adjustment technology responds to hand movements to guide the handpiece in line with the surgical plan.
  • Boundary control on the tibial cut disables resection when the handpiece reaches the surgeon‑defined posterior protection boundary.
