Description

Worksheet: The Knee 1. Is the knee a true hinge joint? No. It has 3 degrees of movement: Flexion, extension and rotation.

2. Are the femoral condyles symmetrical? What does this mean for knee posture? No. Medial condyles project more distally leading to normal valgus of the knee. 3. Which meniscus is firmly attached to the tibia and the joint capsule? The medial meniscus is attached to the medial collateral ligament and the medial capsule. It is more firmly attached to the tibial plateau than the lateral meniscus. 4. What is the role of the patella? The patella acts as a pulley for the quadriceps muscle and stops friction between the same muscle and the femoral condyles. 5. What might happen if you removed the patella? Joint dysfunction, loss of flexion range, and loss of extension strength.

6. How many degrees of flexion are needed to walk normally, climb stairs, and rise from sitting to standing? Approximately 65o walk, 95o stairs , 110o sit to stand. 7. What is the “Q angle”? Why is it important? The Q-angle is formed from a line drawn from the ASIS to the centre of the patella and from the patella to the tibial tubercle (angle between the quads mm and tendon). Normally 14o in men and 17o in women. Wider in women due to a wider pelvis. An increased Q-angle can predispose to problems such as patella subluxation....
