Life-size PVC knee joint model BIX-A1025 — flexion, extension and rotation on a base; washable, for anatomy and musculoskeletal teaching.
...Short answer: BIX-A1025 is a life-size artificial knee joint model that bends, extends and rotates inward and outward, sits on a base, is made of PVC and is washable. Its page displays US $14.74 — the same figure shown on the elbow listing — so treat that number as a reference and confirm it in writing. Among the joint models in this catalogue, the knee is the one that demonstrates both a hinge and a rotation, which is why it carries most musculoskeletal teaching loads.

The knee is the joint where students most often confuse what they can see with what they can feel. A model that both flexes and rotates lets an instructor show that terminal rotation is part of extension, not an add-on. That single demonstration prevents a common examination error.
The literature around joint teaching is increasingly about matching the tool to the complexity of the topic. A 2026 parallel randomised study in Anatomical Sciences Education examined how anatomical topic complexity interacts with teaching-method effectiveness — the practical reading being that a complex, multi-structure topic benefits from a different method than a simple one [1]. A 2026 review in Archives of Orthopaedic and Trauma Surgery addressed isolated compartment arthrosis of the knee, a condition whose explanation depends on compartment anatomy that a model can point to [2]. A Scientific Reports study investigated how knee-brace stiffness affects gait biomechanics — a reminder that the knee is a system, not a hinge [3].
| Not published / needs confirming | Why it matters |
|---|---|
| Actual unit price | US $14.74 also appears on the elbow page; confirm per model. |
| Dimensions and weight | Needed for a shelf plan and for freight. |
| Whether ligaments are represented | Decides whether you can teach restraint, not just motion. |
| Range of motion limits | Natural stops matter when students apply force. |
| Spare base | The base is the part that breaks first in a shared lab. |

Q1. What is BIX-A1025?
A life-size artificial knee joint model that bends, extends and rotates inward and outward, mounted on a base and made of PVC.
Q2. Is it washable?
Yes, the page states the model is washable.
Q3. How much does it cost?
The page displays US $14.74. The same figure appears on the elbow model page, so confirm the price per model before ordering.
Q4. Does it include ligaments?
Ligaments are not mentioned for BIX-A1025. The foot model in the same series (BIX-A1028) explicitly includes a flexible artificial ligament.
Q5. Can it be used for physiotherapy teaching?
Yes, for demonstrating flexion, extension and rotation. It is an anatomy model, not a force-feedback trainer.
Q6. How do I order?
Email cprmodel@adaanatomy.com with model BIX-A1025, quantity and delivery city.
Write to cprmodel@adaanatomy.com for the BIX-A1025 dimensions, the confirmed unit price and a quotation on a joint set. Tell us which joints your curriculum examines — most programmes need the knee first, then the shoulder or the foot, and buying in that order avoids shelf clutter.
