Q

How to perform

Anterior drawer

A

Pt supine, Flex knee to

  • place hands in starting reference position
  • You know from the previous test if the tibia has not sagged back,
  • Keeping elbows straight, pull body straight forward (just rock body), feel for hamstring guarding
  • If it subluxates toward you, you know it’s a PCL tear

How to perform

Flexion Rotation Drawer (FRD)

A

pt in supine, knee flexed 0-60 degrees * Hug ankle under arm and grab proximal tibia with both hands - Good test because 2 planar and doesn’t hurt them * Valgus and compressive force-trying to take patella to contralateral ASIS - Go fly fishing - Normal knee will see nice smooth motion - Abnormal knee gives wiggle/wabble - Like pivot shift but less aggressive, positive test is subluxation of femur on fixed tibia

Hear a ‘pop’ during MOI 4. Intra articular effusion * ACL supplied by ganicular artery so if you tear it mid-substance it bleeds like mad and get effusion within 24 hours-hemarthrosis

Q

what is an ACL “coper”? How do you know? And what does it mean for them in rehab?

A

* If pt can prevent you from doing pivot shift (meaning they can control their knee motion) it can mean they have good neuro-motor control and are a coper: they can do low level activities w/o surgical reconstruction * If pt prevents you from doing it and they cant control it, they are a non-coper and won’t do well with nonsurgical rehab

73
Q

response

AMRI

A

abnormal: anterior subluxation of the medial side of tibia

74
Q

How to perform

Apley’s Compression and Dynamic Compression (DDV)

A

pt is prone 1) Apley’s Compression: posterior horns * Flex knee 90 degrees, hands over calcaneous * Compress, internally and externally rotate it 3 times * Looking for replication of joint line pain, maybe some snapping, cracking, clicking, clunking, pseudocatching, locking 2) Apley’s Dynamic Compression (DDV) * Make sure you put a towel/pillow or something under the patella so it isn’t being crushed by the table * Same positioning as previous test * Compress, externally rotate, and take knee into full extension-3 times * Repeat with internal rotation

75
Q

indications

AMRI

A

(PCL must be intact to perform the test) 1. History of macrotrauma including twisting, deceleration MOI * 80% or more of ACL injuries are non-contact 2. Giving way-could be effusion creating an arthrogenic inhibition that doesn’t let quads fire normally * Not always due to a ligament instability issue * Can also be related to arthritis 3. Hear a ‘pop’ during MOI 4. Intra articular effusion * ACL supplied by ganicular artery so if you tear it mid-substance it bleeds like mad and get effusion within 24 hours-hemarthrosis

76
Q

How to perform

Clancy step-up test

A

Pt supine Flex knee

77
Q

How to perform

Valgus stress

A

pt supine, perform with knee at 0 and at 30 degrees flexion Stand on outside of the leg. position it so the joint line is at your closest thigh. Face foot. If they have some recurvatum, back of to neural (0 degrees) for 0 degree test, don’t test them in hyperextension 1) Valgus stress test (0 degrees): * Keep their thigh on table, put your thigh on their lateral joint line * Palpate medial joint line with one hand and grab distal tibia with other * Close joint first, give 3 valgus stresses - Rhythm should be: close-open, close-open, close-open * Not much happens because this is closed packed position 2) Valgus stress (30 degrees): * Flex knee to 30 degrees _ make sure their knee can flex off the edge of the table so calf is not hitting table * Same thing as 0 degrees but flexed to 30 degrees * Hardest thing is to keep their hip from rotating

78
Q

A

ACL, middle 1/3 of lateral capsule

Q

indications

80
Q

response

Valgus stress

A

reproduction of symptoms, pain, gapping??

81
Q

response

Active Tracking CKC

A

1st squat: looking to see what entire kinetic chain is doing 2nd squat, check for true chondral involvement-put finger right over patella to feel for crunching/grinding 3rd squat, make diamond over patella, palpate peri-patella soft tissue

82
Q

Why did we learn the Dial test?

A

It is being used more and more common in clinics. We should use the other four rotary instability tests we learned.

83
Q

How to perform

Sag Test

A

Pt supine Flex knee

84
Q

response

Dial Test

A

Externally rotate at feet and you are looking for one side to ER proportionally more than the other side o Then it shows that the posterior part of the tibial plateau is subluxating back into the area where the arcuate ligament is o If that is injured, the tibia will subluxate into that weak area that is loose Looking for same sign during part 1 and 2 o This is a positive test

pt supine, perform with knee at 0 and at 30 degrees flexion Stand between leg and table. position it so the joint line is at your closest thigh. Face foot. If they have some recurvatum, back of to neural (0 degrees) for 0 degree test, don’t test them in hyperextension 1) Varus stress (0 degrees): - Want to prevent their leg from rolling up your thigh * Palpate inferior pole of patella and slide finger laterally to be over lateral joint line - Palpate with index finger and use other fingers to support the leg since it is off the table more with this test - Other hand grabbing ankle wherever is comfortable * With knee in full extension, close the joint first, then give varus stress until you feel the end feel and let if spring back, you should feel/see it clunk back in a normal knee (hysteresis)-repeat 3 times - Everybody has physiologic laxity on lateral side so watch it close 2) Varus stress at 30 degrees - same as at 0 degrees but be more careful to prevent hip rotation

8 Rules of Rotary instability test interpretation

A
  1. PCL is intact and serves as the axis of rotation 2. Properly position the knee into IR or ER to selectively bias the tissues 3. Force is applied in a straight sagittal plane 4. Direction of applied force 5. Which tibial plateau translates in the direction of the applied force 6. Names the rotary instability 7. Anterior rotary instabilities are actually named opposite of the true rotation 8. Posterior rotary instabilities are actually named same as the true rotation
178

Recurvatum, not for meniscus (5)
