Questions Flashcards
List the 3 types of discoid meniscus
- I-block shaped and covers > 80% of the lateral plateau; stable
- II-covers less than 80% of tibial plateau
- III-unstable and is usually an enlarge posterior horn of the lateral meniscus that is unstable and snaps into the intercondylar notch
what is the most involved level for burners/stinger injuries?
C5/6
what phase of the throwing cycle does internal impingement occur? what is impinging?
- late cocking
- posterior labrum and humerus
what is the main difference when comparing medial opening and lateral closing wedge HTO’s?
opening wedge would take slope away and be a better option in a patient with previous ACL/PLC injury
what ligament of the shoulder is the primary restraint to inferior translation?
coracohumeral ligament
what is the most effective test to screen for hypertrophic cardiomyopathy in a young athlete that has family history of sudden death?
echocardiogram
The origin of the LCL is ___ and ___ to popliteus
- posterior and proximal
name to rehabilitation restrictions s/p SLAP repair?
- passive ER with the arm at 90 deg abduction
2. active/resisted biceps exercises
what is the most common direction for a proximal tib-fib dislocation? what is the initial treatment? what are the symptoms?
- anterolateral
- closed reduction with posterior force on the fibular head and flexion of the knee to relaxis the LCL
- intermittent pain and occasional numbness from the affects to the CPN
When is the axillary nerve injured during a laterjet procedure and what is the treatmetn?
- glenoid exposure or graft insertion
- it is usually traction and treatment with observation
what is the transfer for lateral winging involving SAN? what is the transfer for medial winging involving the LTN?
- levator scapulae and rhomboid major/minor laterally
- pectoralis to the inferior border of the scapula
what is the main difference in the affect on the kinematics of the knee with medial closing wedge vs lateral opening wedge osteotomies? what type of deficient knee would this be helpful? what type of knee would this not be helpful?
- opening wedge adds on average 3 degrees of slope
- PCL as the increased slope helps with rollback
- ACL as this increased slope would increase the anterior shear
Chronic exertional compartment syndrome (CECS): what are the levels for resting, 1 min, and 5 min post exercise?
- > 15 mm Hg, > 30 mm Hg, > 20 mm Hg
what is the risk of doing a SLAP repair in a patient > 40 years of age?

what is the best predictor of outcomes after arthroscopic partial menisectomy?
outerbridge cartilage score; so basically the presence and extent of degenerative changes
what is the common presentation of partial biceps rupture?

what is the classic location of a juvenile OCD of the knee?
-posterolateral aspect of the medial femoral condyle
