Term
|
Definition
- tibiofemoral and patellofemoral joints
- tibiofemoral- joined by condyles of tibia and femur
- congruency enhanced by Menisci
- patellofemoral- incongruent, contained in joint capsule
- patella- divided by vertical ridge, convex
- anterior surface of the femur- concave-divided by intercondylar groove
|
|
|
Term
| Movements of the tibiofemoral joint |
|
Definition
- flexion/extension= sagittal plane, frontal axis
- rotation- horizontal plane, longitudinal axis
- flexion to extension- tibia internally rotates on femur
- full extension- external rotation locks joint- screw home measurement
- greatest rotation- 90 degree flexion
|
|
|
Term
| Motion at patellofemoral joint |
|
Definition
- patella tracking- motion of patella relative to femoral groove
- patella glides on femur during flexion/extension
- flexion- slides distally
- extension- slides proximally

- patella
- ligamententum patellae tendon
- tibial tuberosity
- tibial plateaus
- head of the fibula
- lateral malleolus
- lateral epicondyle of the femur

Definition
| Superior border- found by placing thumb on iliac crest- tip of third digit touches |
|
|
Term
Ligamentum patellae tendon
|
|
Definition
extends from apex of patella to tibial tuberosity
palpable during knee extension |

|
Term
|
Definition
| upper edges located in soft tissue depressions on either side of ligamentum |

Term
| Flexion/extension Measurement |
|
Definition
- supine

- towel placed under Distal thigh
- stabilise femur
- axis= lateral epicondyle of femur
- stationary arm- longitudinal axis of femur
- moveable arm- longitudinal axis of femur
