When the knee is extended, this cross-shaped ligament is pulled tight and prevents hyperextension

A

ACL-anterior cruciate ligament

17
Q

When knee is flexed, this cross-shaped ligament is pulled tight and prevents hyperflexion

A

PCL-posterior cruciate ligament

18
Q

tibia rotates laterally to tighten ACL and squeeze meniscus between tibia and femur. this accomplishes what?

A

locking the knee

19
Q

what ligament is frequently torn in knee dislocations?

A

ACL

20
Q

transplantation of tissue from person who is genetically different

A

allograft

21
Q

tissue transplant from one site on a person to a different site on the same person

A

autograft

22

stretching or tearing of ligaments without fracture or dislocation of the joint

A

sprain

25
Q

what may result from an overeversion sprain?

A

a Pott fracture

26
Q

when the posterior talar process appears a separate ossicle in an adult and they suffer a traumatic event

A

os trigonum syndrome

27
Q

high ankle sprain/ disruption of interosseous membrane that holds distal ends of tibia and fibula together

A

syndesmotic ankle sprain

28
Q

movement of plantar surface (sole) medially

A

inversion

29
Q

movement of plantar surface (sole) laterally

A

eversion

30
Q

ligament on medial side of talocrural joint that is incredibly strong and rarely tears

A

deltoid ligament

31
Q

ligaments on the lateral side of the talocrural joint and where they pass relative to the malleolus of the fibula

A
  • anterior talofibular ligament (anteriorly)
  • posterior talofibular ligament (posteriorly)
  • calcaneofibular (lateral) ligament (inferiorly)
32
Q

most common cause of ankle sprains

A

excessive inversion

33
Q

what is a “nutcracker injury”

A

os trigonum and surrounding soft tissue is crunched between the calcaneus and the talus and tibia (like and almond in a nutcracker). can lead to inflammation

34
Q

surgical joint replacement

A

arthroplasty

35
Q

What joint replacement surgery has the shortest recovery time? longest?

A

shortest is total knee, longest is total shoulder

36
Q

A

ACL

37
Q

What other ligament of the knee joint is commonly injured by the same forces that would injure the medial meniscus?
