Medial collateral injury

Question 1

What mechanism usually causes this injury?

Answer 1

Extreme eversion during weight bearing.

Question 2

What other problems can happen to the leg from Medial collateral injury ?

Answer 2

The fibula functions to stop over- eversion of the ankle. So this injury could also cause fracture of the distal lateral malleolus.

Question 3

What could be some predisposing factors of Medial collateral injury?

Answer 3

• Lack of physical conditioning; poor muscle tone and shortened and/or contracted joint capsule or tendons.
• Poor proprioception
• Hereditary hypermobility of joints
• Previous sprain

Question 4

What could be some risk factors of Medial collateral injury?

Answer 4

• Accidents
• Overweight/obese can increase kinetic energy to a point that exceeds joint-design stress limits.
• High level athletic training.
• Inadequate training or experience with the physical activity being performed.

Question 5

Why is the medial ligament less prone to injury compared to the lateral ligament?

Answer 5

Medial ligaments are stronger than lateral ligaments and the fibula prevents over-eversion.

Question 6

Why are men more likely to have this injury?

Answer 6

Higher mean height
Increased BMI
Greater athletic exposure to selected sports.

Question 7

Clinical presentation of Medial collateral injury could include:

Answer 7

• Pain, swelling, bruising.
• Cold foot or paresthesia – possible neurovascular compromise.
• Muscle spasm
  The degree of symptoms depend on the extent of damage to ligaments.

Question 8

What test is done for this injury?

Answer 8

Kleiger’s (external rotation) Test

Question 9

Why do these injuries take longer to heal compared to lateral ones?

Answer 9

Due to their thickness and complicated structure
