Flashcards in 04 Lateral Knee Palpations 1 Deck (23):
What pathology is associated with the lateral joint line?
Why do you need to palpate all the way around the joint line?
Most meniscus tears occur in the posterior horns
What pathology is associated with the lateral tibial plateau?
What attaches to Gerdy's tubercle?
What pathology occurs at the ALL?
ALL rupture is pathoneumonic of this pathology
- ACL injury
- ALL avulses bone and midcapsule due to anterior translation and IR
Where is the insertion site of the ALL?
between Gerdy's tubercle and fibular head
What pathology is associated with the fibular head?
- avulsion fracture
- Maisonneuve fx
- hypermobile joint
What causes an avulsion fracture at the fibular head?
Where is a Maisonneuve fracture?
at the fibular neck
What pathology is associated with the popliteal tendon (ridge)?
- popliteal tendonitis
- 2nd most common lateral running injury
Where is the popliteal tendon?
imaginary line from lateral epicondyle to Gerdy's tubercle
Where does the LCL attach proximally?
lateral femoral epicondyle
function of the proximal anterior and posterior tib-fib ligaments
stabilizer - will be involved if the joint if hypermobile
What pathology is associated with the peroneal nerve?
- affected by varus LCL injury
- could get hit there
Where does the lateral retinaculum run?
lateral aspect of patella to lateral femoral epicondyle
What pathology is associated with lateral retinaculum?
- not commonly injured
When is poplieal tendonitis a problem for runners?
- when they'er doing hill running
- femur slides off anterior edge of tibial plateau
What pathology is associated with the LCL?
- ligament sprain
- partial to full thickness rupture
- avulsion from fibular head
What should you do if you can't feel the LCL in seated?
have them go into a figure 4 to stretch the ligament, should jump out
What does the IT band separate?
- biceps femoris
- vastus lateralis
What function does the ALL serve?
stabilize transverse plane from micro-rotation
