Human Knee Active Learning Kit
A life-size reproduction of a real knee designed to engage students, healthcare professionals, athletes, and patients in hands-on, active learning.

Fully functional anatomy
Knee motions are complicated. This is the only knee model on the market (that we know of) that fully and realistically reproduces the complex motions of the knee, including:
- Flexion-extension
- Tibial longitudinal rotation
- Varus-valgus rotation
- Anterior-posterior translation
- Lateral meniscus tracking the lateral condyle
- Knee locking (screw home) mechanism
Anatomy you can take apart
In addition to being fully functional, the knee can also be fully assembled and disassembled so that students can learn anatomy by building it.
This made-to-be-taken-apart design also allows you to do functional knockout experiments, such as removing the ACL to simulate an injury, and easily replace parts.
Anatomy you can move
Muscle actions are complicated. But they're much easier to learn when you can see and feel them in action. With this kit, you can manually simulate muscle contractions to test how different patterns of muscle coordination affect flexion-extension, tibial rotation, patellar tracking, and more.

Real knee anatomy
This knee kit reproduces realistic knee motions because it is based on a real knee. This knee kit is the right knee of the "Visible Woman" from the National Library of Medicine's Visible Human Project®, built from 3D Anatomy Studios' own segmentations of the public domain CT and cryosection image datasets.
Fully documented
Free activity guides and documentation show you step-by-step how to use the kit. Use the guides to prepare your own demonstrations or have students follow the guides for self-guided learning. Each activity includes:
- A PDF worksheet that students can fill in
- An activity guide with photos, videos, and hints
- An educator guide with learning objectives and an answer key (visible only to educators)
How to order
To order your own knee kits, just email us at contact@3danatomystudios.com with the number of kits you'd like to order of each model (Mini, Basic, Full) and we'll send you a quote; see below for current pricing. Your kits will be made by hand in our workshop in Portland, Oregon and shipped directly to you. We can also ship any replacement parts. We accept purchase orders and payment by credit card, check, or ACH.
