TiRobot Recon Joint Replacement Robot

TiRobot Product Family: TiRobot II (Spine & Trauma) | TiRobot Recon (Joint Replacement) | TiRobot Sirui (AI Full Platform)

TiRobot Recon extends Tinavi’s orthopedic surgical robot platform into the joint replacement segment, addressing total knee and total hip arthroplasty with purpose-built navigation and cutting guidance capabilities.

Product Overview

Approved by NMPA for total knee arthroplasty in 2023, TiRobot Recon (also marketed as Tianji Joint) marked Tinavi’s expansion beyond its established spine and trauma franchise. The system received additional NMPA approval for total hip arthroplasty indications in 2024, completing coverage of the major joint replacement procedures.

TiRobot Recon builds on the TiRobot II hardware platform while introducing specialized software and workflow adaptations for joint replacement surgery. This architectural approach enables hospitals already equipped with TiRobot II to expand capabilities without requiring entirely separate robotic systems.

Key Features

Built on the TiRobot II hardware platform, TiRobot Recon adds dynamic soft tissue balancing and free osteotomy guidance for total knee and hip arthroplasty without rigid patient fixation.

• Intelligent Planning (简捷规划): Streamlined preoperative and intraoperative planning workflow reduces setup complexity
• Dynamic Balancing (动态平衡): Real-time soft tissue balance assessment during knee replacement procedures
• Free Osteotomy (自由截骨): Flexible bone resection guidance accommodating varying anatomical presentations
• Seamless Tracking (无缝随动): Continuous navigation without rigid patient fixation requirements

The system addresses clinical challenges in traditional joint replacement, where two-dimensional imaging and brand-specific instrumentation create variability in prosthesis alignment and soft tissue balancing.

Technical Specifications

Approved for TKA in 2023 and THA in 2024, TiRobot Recon uses CT-based preoperative planning with intraoperative optical tracking and supports multiple prosthesis brands.

Clinical Applications

TiRobot Recon provides navigation and positioning support for joint replacement surgeons, with primary applications in:

Total Knee Arthroplasty (TKA)

• Bone resection guidance for femoral and tibial cuts
• Implant sizing and positioning optimization
• Soft tissue balance assessment
• Gap measurement and adjustment

Total Hip Arthroplasty (THA)

• Acetabular cup positioning guidance
• Femoral stem alignment
• Leg length and offset optimization
• Anteversion angle control

The robot-assisted approach aims to improve prosthesis placement accuracy compared to conventional manual techniques, potentially extending implant longevity and reducing revision rates.

Regulatory Status

TiRobot Recon currently holds NMPA approval for the Chinese domestic market only. International regulatory submissions have not been announced as of January 2026.

Market Context

The joint replacement robot segment represents the fastest-growing category within China’s orthopedic surgical robot market, with 2023 market size reaching CNY 697 million and 66% year-over-year growth according to industry data. With TiRobot Recon’s approval, Tinavi became the only domestic company offering a single robotic platform covering spine, trauma, and joint replacement procedures.

Competitive products in China’s joint replacement robot market include systems from Stryker (Mako), Smith & Nephew (NAVIO), and domestic entrants such as Jianjia Medical’s ARTHROBOT.

Frequently Asked Questions

What joint procedures can TiRobot Recon perform?

TiRobot Recon is approved for total knee arthroplasty (TKA) and total hip arthroplasty (THA). The TKA indication was approved in 2023, followed by THA approval in 2024.

Is TiRobot Recon a separate system from TiRobot II?

TiRobot Recon shares the TiRobot II hardware platform but includes specialized software and instrumentation for joint replacement procedures. Hospitals with existing TiRobot II installations may be able to expand capabilities through software and toolkit additions rather than procuring entirely separate systems.

How does TiRobot Recon compare to Mako?

Both systems provide robotic assistance for joint replacement surgery. Mako (Stryker) has longer market presence and FDA clearance for the US market, while TiRobot Recon is domestically developed with NMPA approval for China. Direct clinical outcome comparisons have not been published as of January 2026.
