Hip
Which ligament is the "Y" ligament and what is it's purpose?
Iliofemoral; prevent excessive hip extension
-can be used as passive support in standing
The ACL limits ___ translation of the femur on the tibia
posterior
What is the "Keystone" bone of the transverse arch of the ankle?
2nd cuneiform
Goniometry is a measurement of ____kinematic motion about a specific joint.
*DAILY DOUBLE!*
Glute med weakness can result in what gait deviation? What occurs?
Trendelenburg: contralateral pelvis drop during SLS
*DAILY DOUBLE!*
Where does the ligamentum teres insert? What is it's purpose?
Fovea capitis- to provide stability to the joint
What arthrokinematic motion occurs at the patellofemoral joint when moving from sit to stand?
patella glides *superiorly*
List the 3 motions that occur in supination
PF, inversion, *add*uction
List at least 2 abnormal types of end feel
1. Springy (rebound)
2. Boggy (edema/swelling)
3. Empty (d/t Pn)
4. Normal (but in wrong joint)
Which joint performs osteokinematic eversion/inversion?
subtalar
toe in gait (knee valgus)
Your Pt has genu recurvatum- what muscle group should you strengthen?
HS
What are the primary structures of the forefoot?
What is the most accurate way to confirm an MMT or Goni measure?
compare to the contralateral side
Your healthy, active Pt has an acute ankle sprain and their inversion MMT from the IE was 1/5. Is this likely accurate?
When performing hip abduction, how would you bias the glute med v. TFL?
glute med = ext and slight ER
TFL = flex and slight IR
Describe the different tensile and compressive stresses at the knee in genu varum v. genu valgum
varum = stretched LCL/compressed medial joint
valgum = stretched MCL/compressed lateral joint
What occurs in a hammertoe deformity?
PIP extended and DIP flexed
List at least 3 reasons we use goniometry in PT
1. order DME
2. compare PROM/AROM to determine patho
3. high intra-tester reliability
4. gives objective data for reimbursement
Which extracapsular structure of the knee is most susceptible to inflammation from prolonged pressure?
prepatellar bursa
Describe the difference between cam and pincer FAI
cam = femoral head is too large (more common in AMAB)
pincer = bony overgrowth of acetabulum (more common in AFAB)
List 3 things that contribute to the screw home mechanism of the knee
1. lateral pull of quads
2. passive tension in ACL
3. large medial femoral condyle
*DAILY DOUBLE!*
What is the difference between S/S in plantar fasciitis v. achilles tendonitis?
Both may have Pn with insertion at calcaneus, but inferior v. posterior + bone spurs & morning pain more likely in PF3
Name the open packed position of the hip, knee, AND ankle
1. hip = 30 deg flex, 30 deg abd, slight ER
2. knee = 25 deg flex
3. ankle = 10 deg PF & subtalar neutral
Your Pt is in prone and attempting knee flexion, but the ipsilateral hip raises off the table. What is occurring?
The quads (rectus femoris) is *passively* insufficient
