17
Q

Anterolateral joint line

A

lateral meniscus

18
Q

Lateral Knee

A

LCL, LM, ITB, or OA

19
Q

Anterior Knee

A

PFPS

20
Q

Posterior Knee

A
  • Joint effusion
  • Mild Gastroc strain
  • PCL Tear
21
Q

Deep Knee Pain

A
  • Cruciate ligaments, Meniscus, OA
22
Q

Sharp, catching pain, locking

A
  • structural problem
  • Meniscus lesion
23
Q

Ottawa Knee Rules states X ray should be performed if

A
  • Age greater than 55
  • isolated patellar tenderness
  • tenderness of the fibular head
  • inability to flex the knee to 90 degrees
  • inability to bear weight immediately after injury
24
Q

Gait cycle on the involved leg with damage

A
  • limited stance phase with lengthened swing phase
25
Q

Classification of Effusion

A
  • Trace: small wave on medial side with down-stroke
  • 1+ : Larger bulge on medial side with down-stroke
  • 2+ : Effusion spontaneously returns to medial side after upstroke
  • 3+ : So much fluid that isn’t possible to move the effusion out of the medial knee
26
Q

Knee Capsular Pattern

A

More flexion loss than extension

27
Q

Lateral Rotation

A

MCL, LCL

28
Q

Medial Rotation

A

ACL, PCL

29
Q

Bundles of ACL

A
  • anteromedial
  • posterolateral
30
Q

History of ACL

A
  • mainly non contact but can be contact
  • Femoral IR with foot planted (Knee ER)
  • WB instability, inability to continue to play
31
Q

ACL evaluation

A
  • Segond fracture at lateral tibial condyle
  • injury to the lateral capsule
  • Resisted isometrics would be strong & painless
  • Hypermobile and painful joint play
32
Q

What does Pivot shift test?

A
  • Anterolateral instability
  • Lateral tibial plateau subluxates in extension
33
Q

Decision making for a patient with an ACL tear is?

A

biased toward surgical reconstruction

34
Q

ACL classification

A
  • Non-coper: cannot return after injury, knee giving away
  • Adapter: adapt to less intense activities to avoid
  • Potential Coper: good potential to cope with ACL deficiency
  • Coper: can resume all preinjury activities
35
Q

ACL copers

A
  • no or mild knee effusion
  • full active knee ROM
  • At least 70& Quad strength
  • no knee pain
  • can hop on involved knee
36
Q

Phase I goals for ACL non-operative rehab

A
  • reduce swelling & inflammation
  • normalize knee motion (primarily extension)
