direct contact (contusion) or a muscle strain
poorly treated contusions result in
myositis ossificans traumatica
S&S of muscle contusion
tightness
history of forceful impact
inability to contract muscle
swelling
what muscle groups are most likely to sustain muscle strains to the thigh

which are usually weaker & more susceptible to strain, hamstrings or quadriceps?
hamstrings
____ & ______ are important in a recovery program for strains [dont favor one over the other]
stretching & strengthening
S&S muscle strains to thigh
weakness inability to contract visible defect sharp pain swelling
1st aid muscle strains to thigh
RICE
crutches [if necessary]
medical evaluation (*physician)
patellofemoral joint injuries are aka
knee cap joint injuries
____ & ____ injuries both affect patellofemoral joint & may be debilitating
acute & chronic
what bone injury is associated with knee cap joint injuries
osteochondritis dissecans (OCD)
explain osteochondritis dissecans (OCD)
small pieces of bone are dislodged from a joint & float within a capsule
what makes OCD so dangerous
bone fragments can block or lock a joints motion & cause damage to joint surfaces
S&S OCD
swelling
knee may lock
pain with use

1st aid OCD
ice
compression
crutches
*physician

small fluid filled sacs located strategically
how many bursae in the knee region?
numerous, only a few are typically injured
inflammation of a bursae sack can be caused by
direct trauma
overuse
infection

pre-patellar bursae
S&S bursitis
swelling (h20 balloon)
pain with pressure
report of direct trauma to knee
1st aid bursitis
rest
ice
compression
chronic: anti-inflammatories, removal
Patellar dislocation/subluxation is often caused by
quick cutting motion that generate a great deal of abnormal force within the knee
in patellar dislocations/subluxations, the patella moves _____ and may ______, instead of moving normally
laterally, dislocate
what is it called when the patella is dislocated and returns to its position spontaneously
subluxation
S&S patellar dislocation/subluxation
swelling
pain
abnormal movement
medial patella pain
1st aid patella dislocation/subluxation
ice
