Plan precisely – before the first anchor is set.
RotaPlan™ is a planning system for rotator cuff repair: an interactive 3D model of the shoulder, its bone built automatically from the MRI, in which you classify the tear, place anchors and rehearse the repair before surgery.
- Utility model registered (DPMA)
- Made in Germany
- Research prototype
Today, the plan lives in the surgeon’s head
Rotator cuff repair is one of the most common procedures in shoulder surgery. Yet it is still planned from a subjective reading of the MRI: surgeons scroll through 2D slices and assemble a 3D picture of the tear in their head.

The real situation often only becomes clear during arthroscopy. And once the anchors are in, hindsight sets in: one more anchor, placed a little further apart, might have been the better choice.
Tear size, retraction and tissue quality all matter – but they are rarely measured in a reproducible way. To our knowledge, no commercial planning system exists for this soft-tissue reconstruction.
From MRI to repair plan in four steps
Import MRI
Load a de-identified shoulder MRI. RotaPlan checks image quality and finds the series each measurement needs.
3D model
AI builds the bone model from the MRI. Automatic segmentation of the rotator cuff tendons and the tear is in development.
Tear analysis
Size (Cofield) and retraction (Patte) are measured from the 3D model, fatty infiltration (Goutallier) where the muscles are segmented; pattern (Burkhart) and depth you set. You confirm or override every value.
Explore & simulate
Place anchors freely on the 3D humeral head, pull the tendon towards the footprint and compare constructs – then send the signed plan to PACS.
You explore, you decide – RotaPlan makes the tear visible and testable in 3D.
What the prototype does today
3D shoulder modelRotate the humeral head freely and see tendon, tear edge and footprint in space – from anterior, lateral, superior or posterior.
Standard grading, traceableCofield, Patte, Goutallier and Burkhart on one panel. Measured values come pre-filled and show where they came from; the surgeon confirms or overrides each one.
Compare constructsTwo anchor constructs side by side on the same shoulder – a double-row against a single-row repair, for example – each with its own warnings.
Interactive simulatorGrab and pull the tendon, place anchors and sutures, and watch the repair: how far the tendon reaches and where the footprint stays uncovered.
Who it’s for
Shoulder surgeons
Designed to support reproducible planning and a well-founded choice of technique – in 3D, before the first portal.
Hospitals & centres
Standardised planning, a teaching mode for residents and the signed plan stored in PACS.
Medtech
An implant-agnostic planning platform – open to partnership and licensing.
Where we are
RotaPlan is a working research prototype, protected by a utility model registered with the German Patent and Trade Mark Office, and not yet a CE-marked medical device. Next, we want to validate it on real cases – together with clinical partners.
