Q

pes anserine bursitis

A

inflammation of the anserine bursa located between pes anserinus and the MCL, results in constant, aching pain, aggravated by activity, such as climbing stairs, specifically flexion and internal/medial rotation of the knee

Q

what is the adductor magnus muscle

A

is a broad triangular muscle[1] forming a septum which divides the anterior muscles from the posterior aspect of the thigh. It is the largest muscle in the medial compartment. It lies deep to the adductor brevis and the adductor longus.

21
Q

origin of adductor magnus muscle

A

ischial tuberosity

22
Q

insertion of adductor magnus muscle

A

adductor tubercle on medial condyle

23
Q

function of adductor magnus muscle

A

whole muscle: adduct thigh,

upper fibers: flex thigh

lower fibers: extend thigh

24
Q

innervation of adductor magnus muscle

A

tibial division of sciatic nerve, upper fibers are posterior division obturator nerve

25
Q

hamstring injury

A

can be a muscle strain or tear, but can also hamstring tendinopathy

26
Q

what are the grades of hamstring injury

A

grade 1-small disruption in structural integrity, grade 2 is partial tears with some intact muscle, pain present, definite loss in strength, grade 3, severe, hematoma (blood seeping through),

27
Q

genicular anastomosis

A

descending branch of lateral femoral circumflex artery descends anterior thigh, supplies genicular anastomosis, descending genicular artery arises from femoral artery in adductor canal, supplies genicular anastomosis

28
Q

sciatic nerve tibial division comes from what?

A

L4 to S3

29
Q

common fibular division

A

L4 to S2

30
Q

boundaries of

A
31
Q

boundaries of popliteal fossa

A

superomedially, semimembranous muscle, semitendinous muscle, superolaterally-biceps femoris, inferolaterally-lateral head of gastrocnemius, inferomedially-medial head of gastrocnemius

32
Q

floor of popliteal fossa

A

popliteal surface of femur, oblique ligament, from semimembranous tendon, posterior division of proximal tibia

33
Q

superficial to deep of popliteal fossa

A

nerves, popliteal veins, branch and lymph nodes, then thirdly, popliteal artery and branches

34
Q

femoral artery becomes what after passed through adductor hiatus

A

popliteal artery

35
Q

popliteal artery branches into what

A

posterior and anterior tibial arteries

36
Q

genicular anastomosis supplies what

A

articular capsule and ligaments of knee joint

37
Q

popliteal vein becomes femoral vein after transvering adductor hiatus

lies superficial to and in the same fibrous sheath as the popliteal artery

formed by union of anterior and posterior tibial veins

termination point of small saphaenous vein

A

popliteal vein

38
Q

popliteal vein, what is route

A
39
Q

tell me about lymphatics at the knee

A
40
Q

genicular anastomosis supplies what

A

important collateral circulation, articular capsule, ligaments of knee joint

41
Q

tibial nerve innervates what

A

posterior leg muscles, knee joint, skin on posterior leg via medial sural cutaneous nerve

42
Q

common fibular nerve

A

leaves popliteal fossa by passing superficially to the lateral head of gastronemius, winds around head and neck fibula (susceptible to injury)

innervates anterior leg muscles via deep fibular nerve

lateral leg muscles via superficial fibular nerve

skin on posterolateral leg via lateral sural cutaneous nerve

43
Q

sural nerve runs with small saphaneous nerve and does what

A

composed of medial sural cutaneous nerve (from tibial neve) and sural communicating nerve (from common fibular nerve or lateral sural cutaneous nerve)

44
Q

distal femoral fractures, metaphyseal fractures

A

transverse fracture across the shaft, most common distal femoral fracture

45
Q

physeal fractures

A

transverse fracture involving epiphyseal plate

46
Q

distal femoral fractures can do what

A

posterior displacement can disrupt neurovasculaturem due to close proximity to femur in popliteal fossa

cold, pale feet, slow distal capillary refuel

nergy injury, motor injury and sensory deficits to dorsal or plantar foot

acute compartment syndrome, increased pressure at closed fascial compartment, most commonly due to hemorrhage and/or edema, symptoms include persistent deep ache or burning pain, paresthesia, pain with passive stretch, muscle weakness

47
Q

popliteal (baker’s cyst), what is

A

swelling of popliteal fossa due to enlargement of the gastrocnemius semimembranous bursa

48
Q
A
