WHat is patellofemoral pain syndrome
messed up tracking of the patella into the femoral trochlear groove, usually due to the groove not being deep enough etc
cant treat, just treat the pain
WHat are the risk factors for patellofemoral pain syndrome
risk factors - decreased quad/hamstring strength, navicular drop, dynamic valgus
What is the clinical presentation of patellofemoral pain syndrome
pain w sitting, stairs, squatting at medial/lateral borders of patella
What is patellar tendinopathy
microtears along tendon, usually caused during eccentric overloading during deceleration (jumping/downhill running)
treated by overloading the tendon for acute inflamation triggering, or by modifying activity
What are the risk factors for patellar tendinopathy
high body weight, pes planus, tightness in quads/hamstrings
What is the clinical presentation of patellar tendinopathy
pain w squats/jumps at tibial tuberosity
What is a meniscus tear? what are the types?
degenerative, longitudinal, flap tear, horizontal, radial
occurs when axial load is transmitted through a flexed/extended knee that is also rotating
can remove meniscus as it wont heal
WHat are the risk factors for meniscus tears
sports or jobs that need kneeling, squatting, or climbing stairs
no arterial supply, so will eventually degenerate
What is the clinical presentation of a meniscus tear?
Pain with knee bending, alongside swelling, popping, clicking, or locking
what is an Anterior cruciate ligament (ACL) tear
partial tear or rupture of ACL caused by deceleration, change in direction, or rotary force while the foot is fixed
What are risk factors for ACL tear
decreased hip strength
*wide Q angle
WHat is the clinical presentation for ACL Tear
pain with weightbearing and swelling due to tearing of arterial supply - lots of redness as well
What is osgood-schlaters disease
traction apophysitis (growth plate) of tibial tubercle for teens
repeated tension and torquw on tibial tubercle, causing bone to grow and cause pain
What is the clinical presentation of osgood-schlatter’s disease
pain with stairs/squats
What is the Trendelenburg sign?
indicates weak gluteus medius during unilateral weight-bearing
What is dynamic valgus
internal rotation and adduction of femur , causes contralateral pelvic drop
is also associated with increased risk for anterior knee pain
What is pes planus
collapse of the medial longitudinal arch, associated with a navicular drop
10mm navicular drop associated with an inceased risk of patellofemoral pain syndrome
what is antalgic gait
limping, with the injured side having a decreased stance phase to eliminate the weight bearing of injured side
most proximal joint will compensate for injured joint
What is the lachman test
assesses stability of ACL, holds pt knee between full extension and 30 degrees of flexion. If there is a mushy or soft end feel when tibia is moved forward, or if the infrapatellar tendon slope disappears, then the test is positive
the test has a high sensitivity and specificity for ACL injury detection
What is the Thessaly test
pt flexes the knee to 20 degrees while standing on one foot and rotates the femur on tibia medially and laterally 3 times
positive if pain medially or laterally on the joint line
high sensitivity and specificity
What is the q angle and why is it important?
angle between tibial tuberosity and asis, is the angle of the hip, a greater q angle gives higher ACL risk due to increased torque during impacts
WHat is specificity?
SPIN - specificity when positive rules in
if positive, for sure has the injury
What is sensitivity
SNOUT - sensitivity, when negative rules out
if negative, for sure no injury
What is the modified thomas test
test knee is at 90 degrees off a table, while opposite knee is flexed to chest. If test knee moves, contracture is present (could be a lot of things, very low specificity)
