Knee 3D models

Knee 3D models to show your patient their lesion and the treatment you recommend. They leave with their model on their phone.

Knee in 3D, anterior three-quarter view, slightly flexed: the femoral condyles covered with cartilage, the tibia, the patella and the fibular head.

The models

Knee 3D models

The knee is under construction: femur, tibia, patella and fibula modeled from real bones, flexion kinematics, cruciate ligaments and menisci. It already opens in clinic.

Cruciate ligaments in progress

The knee modeled from real bones, the rupture replayed on its pivot-shift mechanism, the associated injuries, then ACL reconstruction.

Lesions
ACL: partial or complete tear, tibial spine avulsion. PCL. Menisci (ramp lesion, longitudinal tear, bucket-handle tear, radial tear, root avulsion). Chondral lesion, bone bruises, anterolateral ligament, Segond fracture.
Treatments
Four-strand hamstring ACL reconstruction, in eight steps. Other grafts will follow.

How it works

In the visit, in three steps

Structured information in a few minutes, which the patient can review at home.

  1. 1

    Show

    Open the model and walk through the anatomy: condyles and tibial plateaus, intercondylar notch, cruciate ligaments, menisci.

  2. 2

    Reproduce

    Set the lesion from the exam and imaging: location, type, stage, classification. Then walk through the proposed treatment, step by step.

  3. 3

    Share

    Give the patient the QR code or an image: they find their own case, in their language.

Try it with your next case: the models open in your browser, nothing to install.

Questions

Questions from colleagues

Is the cruciate ligament model finished?

Not yet: it is marked “in progress.” Ligament, meniscal and chondral lesions and the four-strand hamstring reconstruction are in place; other grafts and rehabilitation will follow.

Which associated injuries can be shown?

The menisci (ramp lesion, longitudinal tear, bucket-handle tear, radial tear, root avulsion), cartilage, kissing bone bruises, the anterolateral ligament and the Segond fracture. Each one has its line in the findings given to the patient.

Are the models free?

Yes: the free plan opens every model, to show patients their diagnosis: most conditions and lesions. Treatments and other features are paid options.

Do I need an account?

Not to open a model, set the lesion and walk through the treatment. After about fifteen adjustments, you will be asked to create a free account: it saves your visits, picks them up from one time to the next, and records when the patient opens the link.

What equipment do I need?

Just a web browser, nothing to install: computer, tablet or TV screen in the exam room; the patient opens it on their phone. One click saves an image, without the interface, for the chart.

What happens to patient data?

No patient names are stored. The link given to the patient carries only the state of the model: lesion, treatment, language and visit date. A name written on the image you hand out stays on that image.

Which languages?

English, Spanish, French and Russian. The patient receives the model in the language chosen during the visit, which helps with the roughly 28 million people in the U.S. with limited English proficiency, alongside a qualified interpreter, not instead of one.

Design

Who designed these models

Models designed by Dr. Mikaël Chelli, orthopedic surgeon, based on the reference classifications of each condition. Updated October 1, 2026.
