Q

What are the Two Articulating Surfaces of the Knee and which is Weight Bearing?

A

Tibiofemoral – The Medial and Lateral Condyles of the Femur articulating with the Tibia.
Patellofemoral – The Anterior and Distal Part of the Femur Articulating with the Patella.

The Tibiofemoral Joint is the Weightbearing Joint of the Knee.

Q

Where are the Menisci Attached?

A

Attached at Both Ends to the Intercondylar Area of the the Tibia.
The Medial Menisci is also Attached to the Tibial (Medial) Collateral Ligament and the Joint Capsule.

17
Q

What is a Bursa? What is their Purpose?

A

Synovial Fluid Filled Sac, found between Moving Structures in a joint – with the Aim of Reducing Wear and TEar on those Structures

18
Q

How many Bursae are present in the Patella Region?

A

4 - Suprapatella bursa
Prepatella bursa
Infrapatella bursa
Semimembranosus bursa

19
Q

Where are the Bursae Located?

A

Suprapatella bursa – This is an Extension of the Synovial Cavity of the Knee, located between the Quadriceps Femoris and the Femur.
Prepatella bursa – Found between the Apex of the Patella and the Skin.
Infrapatella bursa – Split into Deep and Superficial. The Deep bursa lies between the Tibia and the Patella Ligament. The Superficial lies between the Patella Ligament and the Skin.
Semimembranosus bursa – Located Posteriorly in the Knee joint, between the Semimembranosus Muscle and the Medial Head of the Gastrocnemius.

20
Q

How many Ligaments are associated with the Knee?

A
5 - Patellar ligament
Collateral ligaments (Tibial and Fibular)
Cruciate ligaments (Anterior and Posterior)
21
Q

Name the Attachments of the Patellar Ligament

A

A continuation of the Quadriceps Femoris Tendon Distal to the Patella. It Attaches to the Tibial Tuberosity.

22
Q

Name the Attachments of the Tibial (Medial) Collateral Ligament

A

Proximally, it Attaches to the Medial Epicondyle of the Femur.
Distally it Attaches to the Medial Surface of the Tibia

23
Q

Name the Attachments of the Fibular (Lateral) Collateral Ligament

A

Proximally to the Lateral Epicondyle of the Femur.

Distally it Attaches to a Depression on the Lateral Surface of the Fibular Head

24
Q

Name the Attachments of the Anterior Cruciate Ligament

A

Anterior Intercondylar Region of the Tibia and Ascends Posteriorly to Attach to the Femur, in the Intercondylar Fossa

25
Q

Name the Attachments of the Posterior Cruciate Ligament

A

Posterior Intercondylar Region of the Tibia, and Ascends Anteriorly to Attach to the Femur in the Intercondylar Fossa

26
Q

What do the Collateral Ligaments do?

A

Stablise the Hinge Motion of the Knee, Restricting any Medial or Lateral Movement

27
Q

Function of the ACL?

A

Prevents Anterior Dislocation of the Tibia onto the Femur

28
Q

Function of the PCL?

A

Prevents Posterior Dislocation of the Tibia onto the Femur

29
Q

How would you Test for Collateral Ligament Damage?

A

Ask the patient to Medially Rotate and Laterally Rotate the Leg. Pain on Medial Rotation indicates Damage to the Medial Ligament and vice versa.
(Most Common Knee Pathology)

30
Q

What is damage to the Tibial Collateral Ligament also likely to Cause?

A

Due to the Attachment to the Medial Menisci Damage to One is likely to Tear the other.

31
Q

What is the Anterior Draw Test?

A

With the Patient’s Knee Flexed attempt to pull the Tibia Forwards. If there is movement the ACL is torn.

32
Q

What is the Posterior Draw Test?

A

With the Patient’s Knee Flexed attempt to push the Tibia Posteriorly. If there is movement the PCL is torn.

33
Q

What is the Unhappy Triad?

A

Damage to the Tibial Collateral, Medial Menisci and ACL.

A lateral force to an extended knee, such as a rugby tackle, can rupture the medial collateral ligament, damaging the medial meniscus in the process. The ACL is also affected, which completes the ‘unhappy triad’.

34
Q

Which bones form the Hip Joint?

A

Acetabulum of the Pelvis and the Femur

35
Q

What is the Intracapsular Ligament of the Hip Joint?

A

Ligament of the Head of Femur. It runs from the Acetabular Fossa to the Fovea of the Femur.
It encloses a branch of the oburator artery.

36
Q

How many Extracapsular Ligaments of the Hip Joint are there?

A

3 - Iliofemoral
Pubofemoral
Ischiofemoral

37
Q

What are the Attachment of the Iliofemoral Ligament? What is its Function?

A

Located Anteriorly. It Originates from the Ilium, Immediately Inferior to the Anterior Inferior Iliac Spine. It Attaches to the Intertrochanteric Line in Two Places, giving the Ligament a Y Shaped Appearance
Prevents Hyperextension of the Hip Joint

38
Q

What are the Attachment of the Pubofemoral Ligament? What is its Function?

A

Located Anteriorly and Inferiorly. It Attaches at the Pelvis to the Iliopubic Eminance and Obturator Membrane, and then Blends with the Articular Capsule.
Prevents Excessive Abduction and Extension.

39
Q

What are the Attachment of the Ischiofemoral Ligament? What is its Function?

A

Located Posteriorly. It Originates from the Ischium of the Pelvis and Attaches to the Greater Trochanter of the Femur.
Prevents Excessive Extension of the Femur at the Hip Joint.
