posterior. 90%
a common syndrome in runners and cyclists that results in an abrasion between the iliotibial band and lateral femoral condyle
IT band friction syndrome
a sudden, sharp pain in the back of the thigh that stops the runner in mid-stride is probably what type of injury?
hamstring injury
what are the two bundles of the ACL?
1.the anteromedial bundle (tight in flexion)
2. the posterior bundle is tight in extention
what movement does the ACL prevent?
anteriortranslation of the tibia.
what movement does the PCL prevent?
posterior translation of the tibia
what are the two bundles that make up the PCL?
1. anteriolateral bundle that is tight in flexion
2.posteromedial bundle that is tight in extention
what movement does the MCL prevent?
valgus angulation of the knee
what movement of the knee does the LCL prevent?
varus angulation
what are the crescent shaped fibrocartilagenous structures that are triangular in cross section, that deepen the articular surface of the tibial plateau and provide stability and lubrication?
the menisci of the knee
what is the MC injury to the knee that requires sx?
meniscal tear
medial meniscal tears occur 3x more frequently than lateral meniscal tears
true
what causes the "popping knee" syndrome upon extention of the knee?
a congenitally round (discoid) lateral meniscus that does not acquire its normal semilunar shape
what ligament of the knee is commonly sprained upon twisting of the knee while foot is firmly planted on ground
ACL. patient hears a pop and feels a tear and acute pain in the knee.
define the unhappy triad?
this is the term given to an injury where the ACL, MCL and Medial Meniscus are torn. usually from a lateral blow to the knee with the foot fixed.
what two tests that if positive indicate an ACL tear?
lachman's, anterior drawer
patient presents with a positive tenderness along the patella tendon?
patella tendinitis. usually in basketball/volleyball players. aka "jumper's knee"
what is osgood-schlatters disease?
inflamm. of the bone and cartilage at the tibial tubercle. this causes excessive pulling of the patellar tendon at the attachment on the top of the tibia. occurs mostly in adolescents where the blood supply to the growing bone cannot keep pace with the stresses placed on it.
30 y/o male cannot actively extend knee. on xray you see + patella alta. what has most likely occurred?
patella tendon rupture
degeneration of cartilage under the surface of the patella, usually causes pain with ascending/descending stairs, running downhill etc.
patella femoral syndrome/ chondromalacia patella or "runner's Knee"
what do you need to rule out if you suspect that a patient has "housemaid's knee"
infection and gout
what are some conditions that can cause sudden swelling (effusion) of the joint?
haemarthrosis, gout, RA, septic arthritis
what is the most common mass in the popliteal fossa that results from fluid distension of the gastrocnemio-semimembranousus bursa?
Baker cyst or popliteal cyst
what is the most common peripheral artery aneurysm comprising 70-85% of the total peripheral aneurysms in the periphery?
popliteal artery
MC cause of shin splints? a general name given to pain at the front of the lower leg.
inflammation of the periostium of the tibia
a visible surface manifestation of an underlying syndrome of venous insufficiency that forces venous blood to escape from its normal flow path and flow retrograde down into a congested leg
vericose veins and telangiectasia
what is the leading cause of preventable nosocomial mortality in the U.S.?
DVT and its sequela, pulmonary embolism
what is virchow's triad?
indicitive for DVT and thus for PE; including 1. venous stasis
2. hypercoaguability
3. vessel intimal injury
what indicates a positive homans sign?
pain/discomfort on dorsiflexion of the foot.
what is the most specific symptom of DVT?
edema. principally unilateral.
what is the well's criteria used for?
probability of a DVT
A d-DIMER assay should only be used to rule out DVT, not to confirm it. T/F
true. they have a low specificity for DVT.
what is the most sensitive and specific test to diagnose DVT?
duplex ultrasonography. 0verall 95% specific
what is the most common injury of the ankle?

name the 3 MC ligaments of the ankle sprained, in order.
1.anterior talofibular
2.posterior talofibular
3.calcaneofibular lig
what constitutes a bimalleolar fx?
both medial and lateral disruption
fracture of the proximal fibula with syndesmosis rupture and associated with medial malleolus fx or deltoid lig. rupture
maisonneuve fx.
a fracture produced primarily by rotational force, an "explosion fracture" produced by axial loading?
tibial pilon fx
a pain that is often worse following activity (rather than during), and is often a palpable thickening over tendon tissues. pain is increased by running and decreased by rest is most likely?
achilles tendinitis
this injury occurs most commonly at the narrowest portion of tendon, approx. 2 inches to point of attachment to calcaneus. MOI usually forceful dorsiflexion with ankle in relaxed state
achilles tendon rupture
what is the #1 MC foot problem?
plantar fasciitis. repeated overstretching of the plantar fascia ligament.
plantar flexion deformity of the PIP joint which is either flexible or rigid. usually accompanied by a flexion deformity of the DIP.
