Card Set Information
injury prevention care
what type of of joint is tibio femoral and what are some characteristics?
largest and most stable in full extension
function of the meniscii:
MOI of meniscii :
rotation & compression
what types of injuries are there on the menisii?
what are symptoms of meniscii injuries and can can u treat them?
treat them by
checking normal muscular function
: partial menisectomy
what the function of medial collateral ligament?
medial stability vs valgus force
limit excessive ER of tibia and IR of femur
MOI of MCL
: shear forces
symptoms and signs of MCL injury and special test that can be done:
: instabiliy and pain
PT joint line, PT origin, PT insertion
+ valgus stress test
: valgus in extension
valgus 15 degreee flexion
how can you treat MCL injruy?
what is the finction of LCL?
taut in extension
slack in flexion
limit excessive varus forces
MOI and S/S of LCL
: shear forces
ER of femur
: same as mcl except to lcl, varus test in extension
Function of ACL:
prevent anterior movement of tibia on fixed femur
prevent posterior movement of femur on fixed tibia
bond femur and tibia
MOI of ACL
IR/ER in position
ER tibia with valgus
combination MCL or LCL
special tests of ACL injury:
valgus in extension
signs and symptoms of ACL injury
giving way/giving out
valgus opening in extension
__ to ___ month reahab for acl injury
what is the difference in females and males in ACL injuries?
2 to 8x greater chancei n females
-smaller acl on average
-horomone levels cause increase in chance of injuring acl
how can you prevent ACL injury?
what is the function of PCL?
prevent posterior translation of tibia on fixed femur
prevent anterior translation of femur on fixed fibia
medial and lateral stability at full extension
stronger than ACL
MOI of PCL
landing on flexed knee
anterior blow to knee
combination with MCL, LCL
S/S of PCL and ways to treat it:
quad strength, surgical vs non surgical
Osgood schlatter disease
common to adolescent knee
pain at patellar ligament insertion
apophysitis of tibial tuberosity
caused by running or jumping
what are S/S of oschgood schlatter and how can it be treated?
gradual degenereation of apophysis--> impaired circulation
surgical low recurrence
oschgood-schlatter but at inferior pole of patella
inflammation at quadriceps insertion=
inflammation of inferior pole of patella
MOI of patellar tendinitis
malalignment of lower extremity
training intensity, frequency, season
patella alta, baja
S/S of patellar tenditis
swelling rare, localized
pain on function.....during and after
how can you treat patellar tenditis?
decrease inflammation and load
cause of ILIOTIBIAL BAND FRICTION SYNDROME (Runner’s Knee)
common in runner and cyclists
what are oseochondral fractures?
articular cartilage and bone
patellar or medial femoral condyle
signs and symptoms of osteochondral fractures
lack of extension
partial or complete seperation of a piece of articular cartilage or subchondral bone
: PIER, immobilize
uncommon caused by direct blow
may have strong isometric KE
