Biomechanics of ligaments and tendons

Question 1

grade 1 sprain of ligament

Answer 1

stretched fibres
normal ROM

Question 2

grade 2 sprain of ligament

Answer 2

considerable portion of fibres torn
increased laxity

Question 3

grade 3 sprain of a ligament

Answer 3

complete tear of the ligament
exccessive joint laxity

Question 4

tendons response to load

Answer 4

larger cross section= higher magnitude of muscle contraction/ force

tendons more stronger then muscle

Question 5

cateogorise tendons tear

Answer 5

complete= no strength or partial= some strentgh

Question 6

hysterises

Answer 6

tendon can return to original shape and size

• the energy loss

Question 7

creep

Answer 7

a stress / forced is applied constant then strain will increase relatively quick then over time it will slow down

Question 8

stress relaxation

Answer 8

• strain/ deformation is kept constant but over time the stress in the tissue will decrease rapidly

Question 9

pregnency impact

Answer 9

increased laxity of tendons and ligaments in the pelvis region

Question 10

mobilisation/ immobilisation

Answer 10

ligaments and tendons remodel in the way they are demanding

Question 11

grafts

Answer 11

extensive biological remodelling but will never replicate the original

Question 12

diabetes influence

Answer 12

higher rate of muscular issues
higher rates of issues in the connective tissues

Question 13

haemodialysis

Answer 13

high tendon ruptures

Question 14

stroids

Answer 14

leads to less collagen synthesis

reduction in energy production

reduction in tendon strength

Question 15

NSAIDS

Answer 15

IMPAIR tendon recovery
