Software-Defined Orthopaedics: Stryker Mako RPS, VELYS AI & the Miniaturization Wave

In joint replacement surgery, the mechanical challenge of bone resection and implant positioning is undergoing a parallel revolution. While soft-tissue robotics focuses on tele-manipulation and cavity access, orthopaedic robotics is becoming intensely software-defined and miniaturized.

1. Stryker Mako RPS: The Handheld Robotic Power System

Following its full commercial rollout on July 16, 2026, Stryker’s Mako RPS eliminates the need for massive robotic gantry arms in total knee arthroplasty. By integrating real-time optical tracking directly into a handheld oscillating saw with active blade adjustment, the system preserves the tactile workflow of experienced surgeons while enforcing plan boundaries with sub-millimeter precision.

2. VELYS Hip Navigation with AI Assistance

DePuy Synthes / J&J’s commercial launch of **VELYS Hip Navigation with AI Assistance** demonstrates the practical power of specialized deep learning. By automating the identification of anatomical pelvis landmarks on live fluoroscopy, the system achieves a **57% reduction in workflow landmarking time**, directly reducing patient radiation exposure and OR turnover time.
