lateral aspect of the knee is supported by ?
muscles
the greatest translation for pcl ?
20 - 30 degrees
what is patellar dislocation MOI ?
forceful knee rotation and quad contraction
- tibia external
- femur internal
acl injury signs ?
- restricted movement
- lateral joint tenderness
pain in and around patella
- most physio visits
lateral knee injuries are injured by what directive force ?
varus
weight bearing: femur moving anteriorly
non weight bearing: tibia moving posteriorly
what is the patellar dislocation test ?
lateral apprehension test
acl injury test ?
anterior drawer and lachmans test
intrinsic factors of PFP ?
- lower chain allignment
- excessive pronation
- pull of quads
- shortened muscles
- poor pelvic femoral control
which ligament is intra capsular ? which ligament is extra capsular ?
lateral - extra
medial - intra
why is medial menisic more stable ?
thicker and tighter
what are the signs and symptoms of patellar dislocation ?
symptoms: shift or pop, swelling
signs: loss of knee function, tenderness over medial patella
pcl MOI ?
falling on a flexed knee
describe q-angle ?
- femur and tibia coming together
- higher than 20 degrees: instable by pulling patella laterally
what has more support over mcl ?
cruciates
what are two mechanisms of injury for subjective knee assessment ?
varus : lcl
valgus: mcl
MOI for acl injuries ?
- valgus after mcl
- deceleration / internal rotation
- quads active
pcl signs and symptoms ?
symptoms: pop or crack, pain in back of knee
signs: minimal swelling
how to treat patellofemoral pain?
initial phase: police/peace and love, decrease swelling
repair phase: strengthening muscle function
remodeling phase: increase training intensity and frequency (low weight high reps)
acl prevents what during weight bearing and non weight bearing ?
weight bearing: prevents femur moving posteriorly
non weight bearing: prevents tibia moving anteriorly
what are the ottawa knee rules ?
- over 55
- tenderness over patella and fibular head
- cannot flex 90 degrees
cannot weight bear or walk 4 steps
- rapid deceleration
- anterior tibial dislocation
