ch15: kn Flashcards
(29 cards)
medial vs lat meniscus
medial: more semicircular
lateral: more round
medial more injured bc more secured onthe tibia = less mobile
outer surface of meniscus most vascular
ballotable patella test
patella swelling
procedure: PUSH patella downward in patellofemoral groove
swellin intra-articular= fluid under patella cause it to rebound, exhibiting the outlines of a floating patella
extra-articular= click or definit stoppping point is felt when patella strikes the patelofemoral groove
godfrey sign
pt supine
90deg hip flex
90deg kn flex
leg supported by AT
observation of tibial sag
+ve = PCL
slocum drawer test
anteromedial rotary instab
ant drawer position + tibia ext rot or medial rot
+ve w/ lat rot = MCL, oblique popliteal lig, posteromedial capsule, ACL
+ve with medial rot: anterolateral instability
cross-over test
anterolateral/media rotary test
- pt weight bearing
- cross uninjured limb infront (ALRI)
- cross uninjured limb behind (AMRI)
hughston posteromedial drawr test
posteromedial rotariinstability
external rotation recurvatum test
lift big toe of pt of table
+ve= tibia pushed post and/or rotates on the lateral aspect by excessive amount = posterolat instab only if PCL torn
prox tibfib syndesmosis test
AP PA glide of fibula on tibia
+ve= perceived mvt of the fibula on the tibia
ant shift= damage prox post tibfib lig
post shift= damage to prox ant tibfib lig
what is the q angle
angle btw the line of resultant force prod by the quads and the line of the patellar tendon
normal q angle
weight bearing= 12M-22F
mediopatellar plica test
kn 30deg flex
push patella medially
+ve = pain
plica stutter test
seated at edge of table
AT palpating patella
pt extends kn
+ve if patella stutters btw 45-60deg flexion
patella mobility
medial glide= haf width
lateral glide= half width
lat laxity = risk dislocation
patella grind test
+ve= pain felt, grinding sound is heard
pathology of the patellar articular cartilage
clarke sign
pressure downward on patella during quad contraction
+ve: pain, unable to keep contraction
chondromalacia patellae
waldron test
plapate patella during slow deep kn bends
+ve= crepitus, pain, catching or improper tracking
chosdromalacia patella
patellar apprehension test
pt relax
AT push patella lat
if show of apprehension = +ve patella sublux
bursas inkn
- prepatellar
- infrapatellar
- pes anserine
- tibial colateral lig
bakers cyst
any synovial herniation of the post jnt capsule or bursitis on the post aspect of the kn
chodromalacia patella
true degeneration in the articualr cartilage of the patella that result when compressive forces exceed normal physical range.
surgical finding that represent areas of hyalin cartilage trauma or aberrant loading, not cause of pain
patella plica
fold in the synovial lining that projects into the cavity
triggered by direct blow or inflammed from overuse
moviegoer sign
patella plica indication
inc pain withprolonged sitting
grades os osgood-schlatter
1- pain after activity resolves after 24h
2- pain during and after activity that does not hinder performance and resolves after 24h
3-continous pain thatlimits performance and daily activities
sinding-larsen-johansson disease
excessive strain occurs on the inf patellar pole at the origin of the patellar tendon
- usually childre 8-13
distal femoral epipheseal fx
more common then prox
- more serious bc : possible arterial damage to the growth plate
