1

Which is the largest, most superficial joint?

The Knee!

2

Stability of the knee is dependent on:

The strength and actions of the surrounding muscles and ligaments

3

The 3 articulations of the knee are:

1) Lateral femerotibial joint
2) medial femerotibial joint
3) femoropatellar joint

4

Which muscle's tendon travels through the synovial joint capsule of the knee?

The Popliteus m.

5

What structure connects the vastus medius m. to the suprapatellar bursa?

The Articularis genu m.

6

Of the 12 bursae around the knee joint, which four communicate with the synovial cavity?

1) Suprapatellar
2) Popliteus
3) Anserine
4) Gastrocnemius

7

Which are the 5 extracapsular ll.?

1) Patellar l.
2) Fibular collateral l.
3) Tibial collateral l.
4) Oblique popliteal l .
5) Arcuate popliteal l.

8

When viewed from the posterior, the cruciate ligaments form a letter x. Which l. is which?

The ACL extends S, M->L and A->P
The PCL extends S, L->M and P->A

9

Multiple true/false. The ACL:
1) Is stronger than the PCL
2) Extends superio-posterio-laterally.
3) Prevents anterior displacement of femur on tibia.
4) Prevents hyperflexion of the knee joint.

ACL
1) F. Weaker than PCL
2) T. "ACL-SPL"
3) F. posterior displacement of F on T
4) F. hyperextension

10

Multiple True/False: The PCL:
1) Is stronger than the ACL
2) Extends superio-anterio-medially.
3) Prevents posterior displacement of F on T.
4) Prevents anterior displacement of T on F.
5) Stabilizes femur when weight is on flexed knee.

PCL
1) T. Stronger than ACL
2) T. "PCL-SAM"
3) F. Pd-FonT
4) F. Ad-TonF
5) T. "ACL-walking downhill"

11

A blow to the lateral side of the knee may cause:

"Unhappy Triad"
1) Rupture of the TCL
2) Concomitant tearing of the medial meniscus
3) Tearing of the ACL

12

Give the structures damaged and the clinical sign for the following injury:
-Semi-flexed knee
-hyperextension with force directed anteriorly

ACL Rupture
"Anterior Drawer Sign"

13

Give the structures damaged and the clinical sign for the following injury:
- extended knee
- blow to lateral side

1) TCL
2) Medial Meniscus
3) ACL
"Unhappy Triad"

14

Give the structures damaged and the clinical sign for the following injury:
- flexed knee
- excessive force directed posteriorly

1) PCL
2) may include FCL or TCL
"Posterior Drawer Sign"

15

Give the structures damaged and the clinical sign for the following injury:
- flexed knee
- excessive lateral twisting

1) TCL
2) Medial Meniscus
3) ACL
"Unhappy Triad"
