Management Final Exam Solved
Correctly To Score A+
Clotting Phase CORRECT ANSWERS 1. Rupture of blood and lymphatic vessels
2. Plasma enters interstitial tissues
3. Exposure to proteins initiates changes
4. Platelet plug forms

Inflammatory Phase CORRECT ANSWERS 1. Defends against harmful substances
2. Kinins, prostaglandin and histamine initiate inflammatory response

Proliferative/Fibroplasia Phase CORRECT ANSWERS - Scar formation
- Fibrin matrix broken down
- Scar tissue forms if granulation tissue is not completely removed
- Type 3 collage gradually replaced with type 1

Maturation/Remodelling Phase CORRECT ANSWERS - Decreased fibroblasts
- Denser collagen
- Decreased vascularity

Extracapsular Ligaments of the Knee CORRECT ANSWERS - Patella ligament
- MCL
- LCL
- Oblique popliteal
- Arcuate popliteal

Intracapsular Ligaments of the Knee CORRECT ANSWERS - ACL
- PCL
- Transverse
- Meniscofemoral
- Coronary

MCL CORRECT ANSWERS - Medial meniscus attachment
- Resists valgus force
- Higher risk of injury

LCL CORRECT ANSWERS - No meniscal attachment
- Resists varus force
- Splits biceps fem tendon

Anterior Cruciate Ligament CORRECT ANSWERS Decreases anterior translation of the
tibia and controls rotation and hyperextension

, Posterior Cruciate Ligament CORRECT ANSWERS Decreases anterior translation of
the femur

Examination of the Knee CORRECT ANSWERS - Where is the pain?
- What was the MOI?
- Swelling?
- Locking or clicking?
- Sensation of instability?

Common MOI's CORRECT ANSWERS - Direct blow
- Hyperextension
- Hyperflexion
- Fall on flexed knee
- Varus (LCL + PCL, meniscus) or Valgus (MCL, ACL, meniscus)
- Rotational (ACL, meniscus)
- Overuse

ACL Aetiology CORRECT ANSWERS - Common
- MOI: pivoting, landing from a jump
- "Unhappy triad" = ACL + MCL + one meniscus
- Pop/crack, decreased ROM, swelling

PCL Aetiology CORRECT ANSWERS - Less common
- MOI: direct blow to flexed knee, hyperflexion
- Poorly defined pain (mainly posterior), posterior tibial sag, poor control down hill

MCL Aetiology CORRECT ANSWERS MOI: valgus stress to partially flexed knee
- Grade 1, 2 and 3

LCL Aetiology CORRECT ANSWERS - Less common
- MOI: severe high energy varus force
- Surgery

Function of Menisci CORRECT ANSWERS - Deeper articular surface
- Shock absorption
- Disperse body weight
- Decrease friction during movement
- Lubrication and nourishment

Medial Meniscus CORRECT ANSWERS Most likely to be damage due to the fact that it
is firmly attached to the medial collateral ligament and joint capsule

ACL CORRECT ANSWERS Decreases anterior translation of the tibia and controls
rotations and hyperextension
