Human Knee Joint Model, Life Size

Quick Answer: The Human Knee Joint Model, Life Size is a knee joint model at natural size, showing where the femur meets the tibia and the patella, and used to teach the surfaces, ligaments and cartilage of the largest joint in the body.

Structures of the Knee

The knee joins the femur, the tibia and the patella; the fibula sits beside the tibia but does not enter the knee joint itself. The two femoral condyles rest on the medial and lateral parts of the tibial plateau, and between them rise the intercondylar eminences, near which the cruciate ligaments and menisci attach. The patella, a sesamoid bone in the quadriceps tendon, glides in a groove at the front of the femur and increases the leverage of the thigh muscles.

On a life-size model students can see how shallow the tibial surfaces are and why the menisci matter. The medial meniscus is C-shaped and firmly fixed to the joint capsule and medial collateral ligament, so it is less mobile and more often torn; the lateral meniscus is more circular and moves more freely. Around the joint lie several bursae, including those in front of and below the patella, which become inflamed in people who kneel a lot.

Sports injuries are easier to explain with the anatomy in hand: a blow to the outside of the knee can tear the medial collateral ligament, anterior cruciate ligament and medial meniscus together. The listing states life size but not which ligaments or cartilages are shown, so confirm those details. The functional knee joint model adds movement, and the femur bone model shows the upper bone in full.

Specifications

Care & Handling

• Stand the knee joint model upright if it has a base, or lay it on a soft cloth, never balanced on the patella.
• Clean the joint surfaces with a dry, lint-free cloth; fibres caught between the menisci are awkward to remove.
• Keep it out of direct sun, which fades the colours used to separate ligaments from cartilage.

Applications

• Anatomy practicals identifying the condyles, plateau, menisci and patella
• Orthopaedic and physiotherapy teaching of ligament and meniscus injuries
• Explaining knee osteoarthritis and knee replacement to patients
• Discussing kneecap problems and bursitis in sports and occupational health

Why Choose LabEquip

Orthopaedic clinics, physiotherapy colleges and anatomy departments buy a static knee for detailed teaching of the joint’s surfaces and soft tissues. LabEquip keeps it in its biology lab products; use the contact page for questions about the structures shown.

Frequently Asked Questions

Which bones form the knee joint?

The femur, tibia and patella. The fibula lies alongside the tibia and gives attachment to the lateral collateral ligament but does not take part in the knee joint itself.

Why is the medial meniscus torn more often than the lateral?

The medial meniscus is attached to the joint capsule and the medial collateral ligament, so it cannot move away from a twisting force as easily. The more mobile lateral meniscus escapes more often.

What is the unhappy triad?

A combined injury of the anterior cruciate ligament, medial collateral ligament and medial meniscus, classically caused by a blow to the outside of the knee while the foot is planted.

What does the patella do?

It protects the front of the knee and moves the quadriceps tendon further from the joint’s centre, increasing the leverage of the thigh muscles when straightening the leg.

What happens in knee osteoarthritis?

The cartilage covering the joint surfaces wears thin, the bone beneath thickens and small bony spurs form. The joint becomes painful and stiff, and severe cases may need a knee replacement.

What is housemaid’s knee?

It is inflammation of the bursa in front of the kneecap, caused by frequent kneeling. The swelling sits over the patella rather than inside the joint.
