AIJOINT Surgical Planning Software

Product Type: Standalone surgical planning software | See Also: ROPA - Complete surgical robot system that integrates AIJOINT planning

AIJOINT is an AI-powered 3D surgical simulation software developed by Longwood Valley for joint replacement procedures. The platform holds China’s first NMPA-approved AI-assisted orthopedic treatment Class III innovative medical device registration (October 2023) and received FDA clearance in August 2024. AIJOINT can be used as a standalone planning tool or integrated within the ROPA surgical robot system.

Product Overview

AIJOINT transforms preoperative surgical planning through deep learning algorithms trained on over 100,000 patient cases and tens of millions of medical images. The software automatically generates patient-specific 3D reconstructions from CT scan data and produces optimal prosthesis positioning plans based on individual anatomical characteristics.

Traditional joint replacement surgery relies heavily on surgeon experience for implant positioning—a process that introduces variability and extends the learning curve for less experienced surgeons. AIJOINT addresses this by converting expert surgical knowledge into standardized algorithms, enabling consistent high-precision planning across different experience levels.

Key Features

AIJOINT’s deep learning engine, trained on 100,000+ patient cases, delivers same-day surgical planning with 97% accuracy for hip and knee replacement—holding China’s first AI orthopedic Class III NMPA approval and FDA clearance.

  • Same-Day Planning: CT scan data processed and surgical plan generated within hours, compared to 2+ weeks required by some imported systems requiring overseas processing
  • 97% Precision Rate: Clinical validations demonstrate surgical accuracy improvement to 97% compared to conventional experience-based approaches
  • 3D Visualization: Full three-dimensional reconstruction of patient joint anatomy with prosthesis simulation overlay
  • Multi-Procedure Coverage: Supports hip replacement, knee replacement, unicompartmental knee replacement, and revision surgery planning
  • Deep Learning Engine: Algorithms trained on 100,000+ patient cases from leading Chinese orthopedic institutions

Clinical Applications

AIJOINT supports the full spectrum of joint replacement procedures:

Total Hip Arthroplasty (THA): The software calculates optimal acetabular cup positioning, femoral stem alignment, and leg length restoration based on patient-specific pelvic anatomy and femoral geometry.

Total Knee Arthroplasty (TKA): Planning includes mechanical axis alignment, component sizing, rotation alignment, and ligament balancing simulation.

Unicompartmental Knee Replacement (UKA): Precise planning for partial knee replacement preserving healthy compartments.

Revision Surgery: Complex revision cases benefit from 3D visualization of existing hardware and bone stock assessment.

Regulatory Status

RegionStatusDateRegistration Number
China (NMPA)ApprovedOctober 2023国械注准20233211543
United States (FDA)ClearedAugust 2024-
Europe (CE)---

AIJOINT achieved NMPA approval through the innovative medical device fast-track pathway, receiving China’s first AI-assisted orthopedic treatment Class III registration. The FDA clearance in 2024 positions Longwood Valley among few Chinese orthopedic AI companies with dual regulatory approvals.

Integration Capabilities

AIJOINT functions as both a standalone software platform and an integrated component of Longwood Valley’s ROPA surgical robot system. Hospitals can deploy AIJOINT independently for AI-assisted surgical planning without requiring the full robotic system—an approach enabling broader market penetration across different hospital tiers.

The software integrates with 3D printing workflows for patient-specific surgical guide production, completing the planning-to-execution pathway.

Frequently Asked Questions

What imaging data does AIJOINT require?

AIJOINT processes standard CT DICOM images. The software automatically segments bone structures and generates 3D reconstructions without manual intervention.

How long does surgical planning take?

AIJOINT delivers same-day surgical plan generation from CT scan upload. This represents significant time savings compared to imported systems requiring 2+ weeks for overseas processing.

Can AIJOINT be used without the ROPA robot?

Yes. AIJOINT operates as standalone surgical planning software and can be purchased separately from the ROPA robotic system. The software outputs can guide manual surgery or integrate with the robotic platform.

What training is required to use AIJOINT?

The software is designed for intuitive operation by orthopedic surgeons. Longwood Valley provides clinical training and ongoing support as part of the deployment package.
