Overview - What is OrthoGrid AI-Guided Hip Replacement?

OrthoGrid AI-Guided Hip Replacement is a technology-assisted image analysis tool used during total hip replacement. It works with intraoperative fluoroscopy to help the surgical team interpret key measurements, including pelvic position, implant placement, leg length, and hip offset.

Dr. Stewart was the first surgeon in the world to use OrthoGrid's AI-guided technology in anterior total hip replacement, performing the first case in March 2022 at Oakleaf Surgical Hospital in Altoona, WI.

The technology does not replace the surgeon and does not perform the operation. Dr. Stewart remains in control of the procedure, using the information from imaging, his surgical plan, and his clinical judgment to make decisions throughout the case.

Why It Matters in Hip Replacement

Small differences in implant position, leg length, and offset can affect comfort, stability, and how natural the hip feels after surgery. Image-guided tools provide another layer of information while the patient is still in the operating room, when adjustments can be made if needed.

  • Supports assessment of cup position and alignment during hip replacement
  • Helps evaluate leg length and hip offset before the procedure is complete
  • Uses fluoroscopic imaging already common in anterior hip replacement workflows
  • Provides measurement support while Dr. Stewart remains fully in control

Who May Benefit?

AI OrthoGrid guidance may be used for patients undergoing total hip arthroplasty when intraoperative imaging is part of the surgical plan. Dr. Stewart decides whether this technology is appropriate based on anatomy, procedure type, imaging needs, and the goals of surgery.

How It Fits Into Surgery

Before Surgery
Planning the hip replacement
Dr. Stewart reviews your symptoms, exam, imaging, health history, and goals to create a surgical plan tailored to your anatomy.
During Surgery
Fluoroscopic imaging
X-ray images are used in the operating room. OrthoGrid Hip AI can help analyze those images and provide measurement support during the case.
Implant Positioning
Real-time reference points
The technology can assist with assessing pelvic position, cup alignment, leg length, and offset while Dr. Stewart evaluates the hip replacement.
After Surgery
Recovery follows the hip replacement plan
Your recovery timeline is based on the hip replacement procedure itself, your health, the surgical setting, therapy progress, and Dr. Stewart's instructions.

Frequently Asked Questions

No. AI OrthoGrid is not a robot and does not move instruments or perform surgery. It is image-guidance software that helps analyze fluoroscopic images during hip replacement.
No. Dr. Stewart makes the surgical decisions. The technology provides measurement support and visual information that can assist the surgeon during the procedure.
Not necessarily. Dr. Stewart determines whether image-guidance technology is appropriate for your procedure based on your anatomy, diagnosis, and surgical plan.
Recovery is primarily based on the total hip replacement procedure and your individual healing. The technology supports intraoperative assessment, but your post-operative instructions will follow Dr. Stewart's hip replacement recovery plan.
