Sports IOT - Day 3 (Knee&Hip)
**True or False: The acetabular labrum extends around the entirety of the hip socket -
ANSFalse
It's a horseshoe shape
**Which ligament is connected to the femoral head and aids in stabilizing the hip socket? -
ANSLigamentum Teres
**True or False: Most FAI contains mixed pincer/cam lesions - ANSTrue
True or False: FAI can be defined as the repetitive abutment between the femoral neck and
acetabular rim that occurs within ranges of motions which can cause symptoms - ANSTrue
Cam impingement can be defined as - ANSAn aspherical femoral head, usually anterosuperior
"aspherical extension"
All of the following are functions of the acetabular labrum, EXCEPT:
1. Provides a suction seal to the hip
2. Adds stability to the hip by deepening the socket
3. Acts as a shock absorber, with its most thick portion superiorly
4. Serves as an attachment for the ligamentum teres - ANSAnswer = 4
The ligamentum teres is NOT an attachment site
In which compartment of the hip would you address a CAM lesion?
Central
Peripheral
Peri trochanteric - ANSPeripheral
True or False: The articular cartilage of the acetabulum has a horseshoe shape - ANSTrue
True or False: A CAM deformity is a bony overgrowth of the femoral neck and is associated with
chondral defects o n the acetabular transitional zone cartilage, while a pincer deformity is an
overgrowth of the acetabulum and is associated with 'pinching' of the labrum and labral tears -
ANSTrue
True or False: The MPFL is the main passive stabilizer against lateral patellar displacement -
ANSTrue
True or False: The MPFL is tightest in knee flexion - ANSTrue
, When referring to knee lower alignment, what is the normal Q angle for a female? - ANS18
degrees
True or False: The new MPFL kit comes with 3.5SL and Tightrope RT - ANSTrue
Zones of the meniscus are determined by what? - ANSBlood supply
What is the goal of meniscal resection? - ANS- Remove degenerative tissue
- Spare as much of the meniscus as possible
- Reproduce meniscal contour
This is the more C-shaped meniscus that has connections with the ACL and the capsule MCL:
Medial or Lateral? - ANSMedial
Which meniscus is more mobile due to less capsular attachments? - ANSLateral
A meniscus tear in what area is least likely to heal? - ANSWhite-white zone
What does blumensaats line refer to? - ANS- Known as the intercondylar line
- Line drawn along the roof of the intercondylar notch of the femur on a sagittal view of the knee
The ridge of bone that separates the AM and PM bundle of the ACL on the femur is? -
ANSBifurcate ridge
When preparing standard graftlink using a single tendon the ideal TOTAL length before suturing
is? - ANS250-270mm
In the ACL deficient knee, which way does the tibia translate? - ANSAnteriorly
The PCL inserts on the ___? - ANSmedial femoral condyle and posterior tibia
When performing a pediatric ACL reconstruction, the potential complication from drilling across
the physis is? - ANSPremature bone growth
A patient with severe varus deformity in the knee would be at risk for developing what? -
ANSMedial compartment arthritis
Of the major knee ligaments, which one is NOT intra-articular? - ANSLCL
True or False: Females are 4-5 more prone to ACL injury - ANSTrue
TT-TG distance is considered abnormal if? - ANS>20mm
Which condyle of the knee is at 4x greater risk to have an OCD? - ANSMedial
