Double Medical Knee Joint Surgical Robot
Double Medical’s Knee Joint Surgical Robot represents the orthopedic implant manufacturer’s expansion into robotic-assisted surgery, combining AI-powered preoperative planning with precision bone cutting capabilities for total knee arthroplasty procedures.
Product Overview
Developed to complement Double Medical’s established knee prosthesis product line, this surgical robot system addresses the growing demand for precision joint replacement procedures. The robot functions primarily as a positioning and bone preparation tool, enabling surgeons to execute preoperative plans with sub-millimeter accuracy.
The system integrates with Double Medical’s joint implant offerings, supporting the company’s strategy of providing full solutions from surgical planning through implant placement. This equipment-plus-consumables approach aligns with industry trends where surgical robots drive adoption of compatible implant products.
Key Features
For total knee arthroplasty, Double Medical’s robot combines Tencent-developed AI planning trained on an Asian bone structure database with 1.5mm positioning accuracy and 5G remote surgery capability.
AI Preoperative Planning: Developed in partnership with Tencent’s AI capabilities, the planning system analyzes patient CT data based on an Asian bone structure database to generate optimized surgical plans
High Positioning Accuracy: The system achieves positioning accuracy within 1.5mm, meeting precision requirements for bone resection in knee replacement procedures
5G Remote Surgery Support: Enables experienced surgeons to guide or perform high-risk procedures remotely, addressing the uneven distribution of orthopedic expertise across China’s healthcare system
Integrated Implant Compatibility: Designed specifically for use with Double Medical’s knee prosthesis products, ensuring smooth workflow from planning to implantation
Technical Specifications
For orthopedic teams treating knee osteoarthritis, Double Medical’s robot delivers ≤1.5mm positioning accuracy using an AI platform built with Tencent on Asian bone data, with 5G remote surgery support validated across 30+ tertiary hospitals.

Clinical Applications
The robot system supports various knee surgical scenarios:
- Total Knee Arthroplasty (TKA): Primary indication for end-stage knee osteoarthritis
- Complex Joint Replacement: Cases involving severe deformity or bone loss
- Revision Surgery: Secondary procedures requiring precise bone preparation
Clinical validation has been completed at over 30 tertiary hospitals across China, with more than 200 surgical procedures performed during the validation phase.
Regulatory Status
| Region | Status | Date |
|---|---|---|
| China (NMPA) | Approved | 2025 |
| Europe (CE) | Not Applied | - |
| United States (FDA) | Not Applied | - |
The robot received NMPA approval and entered clinical application in Q2 2025. The company has indicated ongoing efforts to obtain additional regulatory clearances for expanded indications and market access.
Clinical Workflow
Preoperative Phase: Patient CT scan data is imported into the AI planning system, which generates personalized surgical plans based on bone geometry and prosthesis selection
Surgical Execution: The robot guides precise bone cuts according to the preoperative plan, with real-time tracking ensuring accuracy
Implant Placement: Prepared bone surfaces receive Double Medical knee prosthesis components with optimized alignment
Market Context
Double Medical positions this robot as a marketing and clinical support tool rather than an independent revenue stream. The strategy targets:
- Hospital equipment upgrade initiatives under national policies
- Strengthening relationships with key accounts
- Driving adoption of compatible knee implant products
- Differentiating against competitors in post-VBP market
The company has announced deployment targets of 500 installations by 2026, covering over 50% of tertiary hospitals nationwide.
