ANSWERS SURE A+
✔✔what contributes to stability of knee - ✔✔Ligaments, Capsule, Menisci, Muscles,
Tendons
✔✔made of fibrocartilage (thick, tough) , it's main function is to bridge the gap between
end of femur and top of fibula - ✔✔meniscus
✔✔________ ligaments help attach meniscus to - ✔✔Coronary
✔✔Outer edge of meniscus (outer 1/3rd is _______ has good blood supply b/c firmly
attached to tibia - ✔✔red zone
✔✔the middle 1/3 of meniscus has a poor blood supply = poor healing - ✔✔pink zone
✔✔, inner third of meniscus has no blood supply and is free floating = not healing itself -
✔✔white zone
✔✔Doesn't produce synovial fluid but soaks it and can expel it as it glides -
✔✔meniscus
✔✔Joint capsule: divided into what four quadrants ? - ✔✔anterior-medial, anterior-
lateral, posterior-medial, posterior-lateral
✔✔joint capsule provides a lot of ____ with ______ - ✔✔stability, rotation
✔✔ligaments of kneejoint capsule - ✔✔MCL, LCL, ACL, PCL
✔✔Short inner, long outer fibres
runs from medial femoral epicondyle and runs to attach to proximal tibia - ✔✔MCL
✔✔MCL; helps prevent _____ motion - ✔✔valgus
✔✔MCL -when you bend knee _____ tightens, extend- long fibres tighten
(extracapsular) - ✔✔short fibres
✔✔MCL; extend-_______tighten (extracapsular) - ✔✔long fibres
✔✔Attaches to femur and head of fibula - ✔✔LCL
✔✔Anterior tibia, then up (superior), back (posterior), out to (lateral) to attach to medial
surface of lateral condyle
, Prevents anterior displacement of tibia on fixed femur, and posterior displacement of
femur when tibia is fixed, hyperextension - ✔✔ACL
✔✔Posterior tibia, then up (superior), forward (anterior), in to lateral surface of medial
condyle
Prevents posterior displacement of tibia on fixed femur or prevent anterior movement of
femur if fibula is fixed - ✔✔PCL

prevents _______ movement (extracapsular) - ✔✔varus
✔✔____ similar to ACL - ✔✔hamstrings
✔✔____ similar to PCL - ✔✔quadriceps
✔✔Fibrocartilage
Medial and lateral
Attached to tibial plateau
Attached to capsule by coronary ligaments
Provides cushioning & stability
Increases synovial fluid circulation - ✔✔menisci of knee
✔✔Extensive & redundant
Resists hyperextension
Provides rotational stability - ✔✔capsule of knee
✔✔most superficial on front of thigh, crosses both knee joint and hip joint therefore
helps a little bit with hip flexion). - ✔✔rectus femoris
✔✔origin of rectus femoris - ✔✔ilium at AIIS
✔✔insertion of rectus femoris - ✔✔patella and patellar ligament
✔✔origin of vests medals (knee) - ✔✔shaft of femur
✔✔origin of vastus medals of knee - ✔✔femur
✔✔all knee muscles insert by - ✔✔quadriceps tendon and patellar tendon on tibial
tuberosity
✔✔function of quadriceps femurs (and vastus) - ✔✔extension of leg at knee
✔✔origin of hamstrings - ✔✔ischium
