Week 5

Question 1

Describe the stages of ligament injury.

Answer 1

Destruction - retraction of ligament ends, form clot, replaced with heavily cellular infiltrate
Repair - Produce scar tissue/ collagen by fibroblasts, organisation of collagen fibre
Remodelling - Continued ligamentisation

Question 2

What is the healing time for the 3 grades of sprains?

Answer 2

Grade 1 = 2-8 weeks
Grade 2 = 2-6 months
Grade 3 = 6-12 months

Question 3

What is the healing time periods for a ligament graft?

Answer 3

Early graft healing = 0-4 weeks
Proliferation = 4-12 weeks ( weakest between 6-8 weeks)
Ligamentisation = 12 weeks -12 months

Question 4

What movements are likely to cause an ACL injury?

Answer 4

Cutting/pivot manoeuvre, single leg landing.

Typically occurs when in 10-30 degrees of flexion with knee in valgus position

Question 5

What are the types of ankle injuries?

Answer 5

Lateral ankle complex sprain (85%), plantar flexion/ inversion
Syndesmotic sprains (10%), hyperdorsiflexion
Medial complex sprains (5%) dorsiflexion, eversion, abduction.
