  1. convex/cavity of 1st MCP joint
    • flex/ext: concave on convex
    • abd/add: convex on concave
    • (for 2-5 it's all concave on convex)
  2. femoral head is oriented which way
    sup ant med
  3. angle of inclination norms
    • 115-125
    • coxa valga is > 125
    • vara is < 115
  4. acetabulum faces which ways
    inf ant lat
  5. iliofemoral lig from where to where
    aka
    • AIIS to intertrochanteric line
    • Y lig
    • lig or Bigelo
  6. bands of iliofemoral / Y / lig of bigelow
    • medial: AIIS to distal intertrochangeric line
    • lat: AIIS to prox intertrochanteric line
  7. iliofemoral lig does what?
    • limits ext and ER
    • lat band limits add
  8. ischiofemoral lig
    where to where
    limits what
    • ischium, post acetabumulum --> greater troch
    • IR, abd, ext (ext bc it attaches so high that in ext it would be pulled forward)
  9. zona orbicularis
    lig around the femoral neck, helping hodl the head of femur in the acetabulum
  10. ischiofemoral bursa is located where
    can cause what pain pattern
    • btwn IT and glut max
    • pain in sciatic distributino
  11. deep trochanteric bursa may hurt when? located where?
    • flexion and IR
    • btwn post lat greater troch and glut max
  12. which arteries supply prox femur
    med and lat femoral circumflex
  13. femoral head gets blood from where?
    foveal artery, which is a branch of the obturator artery
  14. acetabulum gets blood from where?
    sup and inf gluteal arteries
  15. MCL taut/slack when?
    prevents what? gives stability against what?
    • taut in ext
    • slack in flex
    • prevents ER
    • stability against valgus
    • (runs in same dire as ACL)
  16. LCL taut/slack when? prevents what? stability against what?
    • taut in ext
    • slack in flex
    • prevents ER
    • stabil against varus
    • (runs in same dir as PCL)
  17. arcuate popliteal lig from where to where?
    role?
    • Y shaped (w med and lat bands)
    • med band: post border of intercondylar area of tibia
    • lat band: lat epicondyle of femur --> fib head
    • strenghtens posterolat capsule
  18. oblique popliteal lig
    where to where? does what?
    • lat post  inf femur -->tendon from semimembranosus
    • strengthen post medial capsule
  19. meniscopatellar lig
    where
    does what
    • inferolat edges of patella --> lat borders of each meniscus
    • pulls menisci forward with extension
  20. alar fold (knee)
    • from lat patella to med and lat fem condyles
    • keeps patella in contact w femur
  21. infrapatellar fold - what is it for?
    limits compression bc it's compressed by patella tendon in full flex
  22. structures attaching to the med meniscus
    • MCL
    • fibrous capsule
    • semimembranosus
    • medial meniscopatellar lig
  23. structures attatching to the lateral meniscus
    • popliteus muscle
    • lat meniscopatellar lig
    • meniscofemoral lig
    • (not the LCL or lateral capsule)
  24. motion of menisci - they follow which bone when?
    • follow tibia w flex/ext
    • follow femur w IR/ER
  25. fibula rotation in PF/DF
    • PF -- IR 
    • DF -- ER (fib glides sup and post)
  26. spring ligament
    • plantar calcaneonavicular lig
    • sustentaculum tali --> navic
    • supports head of talus
    • helps maintain medial longitudinal arch
  27. windlass effect
    tightening of plantar fascia via toe ext --> supination of calcaneus and inversion of subtalar jt --> rigid lever for push off
  28. tibial rotation in PF/DF
    • PF - ER as it glides post on talus
    • DF - IR as it glides ant on talus
  29. open chain inversion - how does the calcaneus move on the talus?
    add, sup, PF
  30. closed chain inversion - movmnt of calc and talus?
    • sup of calc
    • talus glides lat w abd and DF
    • tibia does ER
    • (reverse for eversion, w tibia doing IR)
