Q

Q- Angle and how to measure it

A

standing with knee extended
align with ASIS, Tibial tuberosity and Patella as axis
Normal = 10-15

Larger the Q angle predisposes to patellar subluxation

Q

Tibial Torsion ( the twist in the tibia itself) And how to measure it

A

Sitting, Knee flexed to 90
fingers of malleoli
then looking down over distal thigh visualize the axes of the knee and ankle
should be 13-18 angle due to lateral tibial rotation

Increased lateral torsion= increases Q angle

Internal torsion= leads to pronation

Q

How to measure the position of the patella

A

Knee flexed to 60 degrees and measure the height of the patella and length of the tendon

Alta= patella tendon is longer by 15-20% than patella height - tight quads

Baja= patellar tendon is 15-20% shorter than patella height

Q

What is the Ballottement test

A

Looks for joint effusion

Pt is supine, pushing from prox and distal knee to center and then push patella posteriorly towards femur

(+)
patella bounces off with distinct impact

Q

What is the Milking Test

A

move fluid to inferior suprapatellar area then to medial area from lat joint line= all fluid will be inferior and medial

Then tap medial area and fluid will then float back to lateral side of joint

Q

What is the joint line tenderness test

A

Looks at meniscal tear

palpate joint line with knee in 90 flexion

(+) reproduces pain

23
Q

Easiest way to palpate the MCL and LCL

A

Lateral- easy to palpate with examined ankle crossed over opp knee

24
Q

What is the pes anserine

A

Insertion for Sartorius, graciliis and semitendinosus

25
What is the closed packed position of Tibiofemoral
full extension
26
What is the closed packed position of Prox tibiofibular
Full DF
27
What is the closed packed position of patellofemoral
Full flexion
28
What is the open packed position of tibiofemoral
25 degrees flexion
29
what is the open packed position of prox tibiofibular
neutral ankle, 25 degrees knee flexion
30
what is the open packed position of patellofemoral
0-5 degrees flexion
31
What is the capsular pattern of the tibiofemoral
Flexion > Extension
32
What is the capsular pattern of the prox tibiofibular
not reported
33
what is the capsular pattern of the patellofemoral
not reported
34
What is the Extensor or Quad lag test
Can be due to muscle atrophy, pain, effusion or loss of mechanical advantage Able to achieve full passive extension of knee and lack of full active extension
35
What is the tibial rotation ( screw home mechanism)
Pt sitting with knee flexed to 90 and palpate the tibial tubercle and point on the patella = so the points make a vertical line pt then actively extends knee You should observe tib rotating laterally on femur Tib rotation can be influenced by subtalar joint motion
36
What position should resisted motion testing be done for the knee?
25 flexion with pt supine or prone
37
What liggs are taut and lax with medial rotation
Collateral are Lax | cruciates are Taut
38
What liggs are taut and lax with Lateral Rotation
Cruciates are Lax | Collateral are Taut
39
What is the lachman test?
For ACL tear pt supine and knee at 30 degrees- then translate tib anteriorly (+) excessive anterior translation
40
What is the Anterior Drawer Test
For ACL tear Pt supine and knee flexed to 90- then translate tib anteriorly (+) excessive anterior translation of tibia or anterior subluxation of > 5mm
41
what is the Anterolateral ( Slocum) test
For rotary instability Perform after (+) anterior drawer test Do an anterior drawer test and test with tibia in max ER If the Tibia moves as much with the ER and Anterior Translation= MCL and Meniscus compromised Then Do the anterior drawer test with tibia in max IR If the translation is the same= LCL and meniscus compromised
42
With a (+) Slocum test in External Rotation What structures are compromised?
ACL, MCL, Meniscus
43
With a (+) Slocum test in Internal Rotation what structuers are compromised?
ACL, LCL, Meniscus
44
What is the pivot Shift Test
For ACL Tear Pt supine. Lift leg in full extension to 45 degrees of hip flexion Then with top hand hold above the knee and place thumb on Fibular head- Applying superior glide to fibula and a force medial on the knee Then with bottom hand at ankle apply force into Internal rotation and pull Lateral on the Tibia (+) If Lateral Tibial plateau subluxes anteriorly
45
What is the Posterior Drawer Test
For PCL tear Pt supine and knee flexed to 90 degrees Then do a posterior glide of tibia (+) posterior subluxation of tibia or excessive posterior translation of tibia
46
What is the Valgus Stress Test
For MCL Place knee joint in max varus and then into Valgus This is done at 5 degrees of knee flexion and then again at 30 degrees of knee flexion (+) pain and laxity or Laxity of medial joint line
47
What is the Varus Stress Test
For LCL Place joint knee joint in max valgus and then into Varus This is done at 5 degrees of flexion ( focus more on anterior and posterior fibers) then again 30 degrees of flexion( focus more on anterior fibers) (+) pain and laxity or laxity of lateral joint line
48
To maximize stress on the collateral ligg of the knee what direction should the tibia be placed in?
External Rotation
49
What is the McMurray Test
For Meniscal Tear can also test for OA pt is supine- one hand on heel of foot and one hand stabilizing the knee Hip and knee are flexed up passively While flexing up place the tibia in ER and Axially load ( push up on tib and down through femur) Then take leg into extension Do test again in Internal Rotation (+) (palpable or audible click or pain during rotation)
50
What is the Apley's compression test
For Meniscus Pt is prone with knee flexed to 90 place downward pressure on foot to compress knee Then IR and ER rotate Tibia (+) pain or reproduction of symptoms
51
What is the Thessaly Test
For meniscal Tear Pt stands Wb on symptomatic leg- holding onto examiners hands then then IR and ER rotates body with knee flexed to 20 degrees Can clinically have them do more than 20 degrees of flexion (+) pain/ reproduction of symptoms or clicking in the joint line
52
What is the moving patellar apprehension test
For patellar instability pt supine with knee extended and ankle off of exam table therapist passively flexes knee to 90 degrees and back into extension while the patella is held in a lateral position then repeated with a medially held patellar position (+) pt exhibits apprehension or quad contraction during lateral glide and no apprehension during medial glide
53
What is Clarke's Sign
For retropatellar pain syndromes Especially chondromalacia pt supine with knee extended apply distal and posterior compression of patella have pt then contract quads (+) pain this though can be positive for asymptomatic individuals
