Current obstacles

Surgeon adoption and trainingSurgeons trained manually hesitate to adopt robotics; retraining carries short-term efficiency losses.
Outcome data and payer confidenceLarge randomized trials are ongoing; payers require stronger evidence before raising reimbursement.

Physics limits

Surgeon still guides the procedureCurrent ROSA systems are semi-autonomous; the surgeon retains decision-making and can override the robot at any time, limiting time savings.
Upfront cost and capital investmentPurchasing and maintaining a robotic system requires a hospital capital budget of $1M+; smaller facilities may not afford it.

How it works

4 parts

Preoperative planning

Image-based surgical blueprint

CT or X-ray images are processed to create a 3D model of the patient's joint; the surgeon plans implant size, position and alignment using this model.

Robotic registration

Tracking anatomy during surgery

Optical or other tracking systems register the patient's real anatomy to the preoperative plan, so the robot knows where it is in the patient's body.

Surgeon-guided execution

Surgeon directs, robot executes

The surgeon operates instruments from a console or through haptic feedback; the robot constrains motion to the planned trajectory, preventing deviation.

Autonomous evolution

AI-guided bone cuts and implant seating

Monogram's semi- and fully autonomous systems use machine learning to optimize bone cuts and implant positioning, reducing surgery time and variation.
