What is Q angle (patellofemoral The angle between the quadriceps muscle
angle) (primarily the rectus femoris muscle) and
the
patella tendon
Male/female differences in Q angle The angle tends to be greater in females
because
the pelvis is generally wider in women
Normal Q angle Knee extension ranges from 13-19
degrees in
normal individuals
Genuvarum Bowlegged/ problem in which the distal
segments
are positioned more medially than normal
Genuvalgum knock knees/ problem in which the distal
segments
are positioned more laterally than normal.
Knees
tend to touch while ankles are apart.
,Genurecurvatum Back knees/ hyperextension, ROM goes
beyond 0
degrees extension
During an open chain knee Open chain- the knee has a concave on
extension convex
what kind of rotation takes place in relationship where the concave tibial
tibia in relation to femur? For condyles
example, the tibia rotates laterally glide posteriorly with flexion and anteriorly
on with
the femur. During open chain knee extension, while the distal end of the tibia
extension, Femur does not rotate moves in
on the same direction
tibia, but tibia rotates on femur. On Closed chain- the knee has a convex on
the other hand, during closed concave
chain relationship, but is reversed when non
reaction, the femur rotates on tibial weight
condyle bearing
When you come up from sit to When going from sit to stand, the femur
standing, what happens at the end must glide
of posteriorly on the tibia as it rolls into
knee extension (now this is the extension
closed chain reaction). At the end At the end of knee extension, the femur
of spins/rotates medially on the tibia
knee extension, the femur spins
(medially or laterally) to lock into
place for optimal standing stability
, What is the patellofemoral pain Patellafemoral pain syndrom: a common
syndrome? What are the common problem
causes of the syndrome, some causing diffuse anterior knee pain and
examples include: around the
knee cap
Common causes- overuse, improper use
of sports
equipment, misalignment of patella,
muscle
imbalance, and tightness in anatomical
structures
Generally considered the result of a variety
of
alignment factors
Femoral triangle fig 7-11 Bordered by the inguinal ligament
superiorly, the
sartorius laterally, and adductor longus
medially
The femoral artery, vein, nerve, numerous
lymph
nodes, and terminal portion of great
saphenous
vein lie within the triangle
Pectineus and iliopsoas muscle form the
floor of
the triangle
External iliac artery ------> which becomes femoral artery--->
which becomes popliteal artery--->
which becomes anterior/posterior tibial
artery--->
which becomes dorsalis pedis artery
