athletes; suprapatellar --> mature athletes
Tendonitis (PTCs) - Answers-jumper's knee = usually chronic/long lasting, can be
disabling, occurs below the knee cap, common in fast growing youth

up/down hills, or overtraining (esp. in jumping sports)
Osgood-Schlatter disease - Answers-inflammation or irritation of the tibia at tibial
tuberosity; caused by extra muscle pulling which causes calcium to build up and form a
bump on the area; seen frequently in young men who are growing b/c the muscles don't
have enough time to lengthen enough to accommodate them; more likely in individuals
that are highly active
iliotibial band syndrome - Answers-an overuse injury caused by the band rubbing
against bone; common causes are structural malalignment and inflexibility, also seen
more often in bowlegged people (varus) because the stance forces the band to curve
out causing more tension; not an emergency situation; inserts at Gerdy's tubercle

ilium - Answers-forms the main "hip bone," contains points of attachment: ASIS =
sartorius, AIIS = rector femoris, PSIS = level of S2, PIIS, and iliac crest; location of
greater sciatic notch (posteriorly); iliac fossa is the site of attachment for many hip
muscles
ischium - Answers-the bone you sit on; contains ischial tuberosity where the hamstrings
originate
Pubis - Answers-pubic symphysis joins the two sides of the pelvis
Femur - Answers-longest + strongest bone; head is directed medially, superiorly, and
slightly anteriorly to fit into acetabulum; contains fovea capitis which holds the bone in
place and is the attachment of the ligament and artery supply to the bone; some bursitis
is seen @ greater trochanter; lessen trochanter is a place for multiple muscular
attachments
Sacrum - Answers-fusion of 4-5 vertebrae; functions as the portal for the sacral plexus;
