Knee - rotator cuff muscles - elbow - wrist Flashcards
ACL
anterior cruciate ligament
PCL
Posterior cruciate ligament
Anterior drawer sign
With patient supine, bending knee at 90 degree angle, increased anterior of tidia due to anterior cruciate ligament injury –> Lachman test is similar, but at 30 angle
Knee exams - tests?
- Anterior drawer sign
- Posterior drawer sign
- Abnormal passive abduction
- Abnormal passive adduction
- McMurray test
- Lachman sign
Posterior drawer sign
With patient supine, bending knee at 90 degree angle, increased posterior gliding of tidia due to posterior cruciate ligament
Abnormal passive abduction
With patient supine and knee either extended or at 30 degree angle, lateral (varus) force –> medial space widening of tidia –> MCL injury
Abnormal passive adduction
With patient supine and knee either extended or at 30 degree angle, medial (varus) force –> lateral space widening of tidia –> LCL injury
McMurray test
With the patient supine and knee internally and externally rotated during range of motion
- pain, pooping on external rotation –> medial meniscal tear
- pain, pooping on internal rotation –> lateral meniscal tear
anterior and posterior in anterior and posterior cruciate ligament refer to
sites of tibial attachment (superior surface)
ligaments of the knee
- anterior cruciate ligament
- posterior cruciate ligament
- lateral meniscus
- medial meniscus
- Lateral collateral ligament
- Medial collateral ligament
Lateral collateral ligament injury - test
abnormal passive adduction
posterior cruciate ligament - test
posterior drawer sign
meniscal tear test
McMurray test
abnormal passive adduction –> injury of
Lateral collateral ligament
lateral meniscal tear - test
McMurray test with internal rotation
common knee conditions
- Unhappy triad
- Prepatellar bursitis
- Baker cyst
Baker cyst?
popliteal fluid collection in gastrocnemius-semimembranosus bursa commonly communicating with synovial space and related to chronic joint disease
Baker cyst is commonly related to
chronic joint disease
prepateral bursitis is also called / definition
Housemaid’s Knee
inflammation of Knee’s largest sac of synovial fluid
prepateral bursitis - can be caused by
- repeated trauma
2. pressure from extensive kneeling
Unhappy triad - presents with
acute knee pain and signs of joint injury / instability
Unhappy triad - common in (why)
contact sports due to lateral force applied to a planted leg
Unhappy triad - problem?
classically consists of damage to
- anterior cruciate ligament
- Medial collateral ligament
- medial meniscus
most common injury - ligament?
medial meniscus
extensive kneeling can cause –> … (at the knee)
prepatellar bursitis
chronic joint disease can cause –> … (at the knee)
Baker cyst
common injury of the knee at contact sports –>
Unhappy triad
