Q

what is the limiting factors for knee medial rotation

A

cruciate ligaments - particularly PCL

17
Q

what is the limiting factors for knee lateral rotation

A

cruciate ligaments - particularly ACL

18
Q

how to carry out circumferential muscle bulk test - calf

A

half laying
measure 5cm below tibial tubercle
repeat 3 times

19
Q

how to carry out circumferential muscle bulk test - thigh

A

half lying
measurre 10cm and 15cm above base of patella
repeat 3 times

20
Q

how to carry out valgus stress test

A 
patient supine
leg between forearm and waist
support thigh with LATERAL hand
support calf with MEDIAL hand just above ankle
push ankle laterally and thigh medially

repeat with knee extended and at 30 degree flexion

21
Q

how to carry out varus stress test

A

patient supine

leg between forearm and waist
support thigh with MEDIAL hand
support calf with LATERAL hand just above ankle
push ankle medially and thigh laterally

repeat with knee extended and at 30 degree flexion

22
Q

how to carry out Lachmann’s test

A

patient supine
pillow under knee (ensures hamstrings relaxed)
grasp lower anterior femur to stabilise
cup posterior upper calf
pull tibia upwards with counter pressure on thigh

23
Q

how to carry out posterior draw test

A

70 degree flexion - patient supine
sit on foot
grasp upper tibia with thumbs on tibial tubercle
push tibia backwards

CHECK TIBIAL PLATAU FIRST FOR RUPTURE

24
Q

how to carry out McMurrays test

A

patient supine
hold under heel, knee flexion
for MEDIAL meniscus - turn foot outwards and palpate posteromedial joint line - extend knee
for LATERAL meniscus - turn foot inwards - palpate posterolateral joint line and extend the knee

25
Q

what is the circumferential muscle bulk test looking for?

A

differential measurements for loss of bulk

26
Q

what is the valgus test looking for?

A

defect in MCL

- excessive joint gapping

27
Q

what is the varus test looking for?

A

defect in LCL

- excessive joint gapping

28
Q

what is the Lachmann’s test looking for?

A

defect in ACL

- excessive anterior displacement of tibia

29
Q

what is the posterior draw test looking for?

A

defect in PCL

- excessive posterior displacement of tibia - more than 1cm

30
Q

what is the McMurrays test looking for?

A

defect in menisci

  • pain or apprehension during extension
  • clicks over joint line

diagnosis must be alongside history of giving way, looking or recurrent effusions

31
Q

how to perform AP tibia

A
  • Patient lying supine with pillow under knee
  • Plinth at mid thigh height
  • Web space over proximal anterior tibia
  • Push down into the bed
32
Q

how to perform PA tibia

A
  • Prone lying with pillow under knee
  • Plinth at mid thigh height
  • Webspace over proximal posterior tibia
  • Push down into the bed
33
Q

how to perform AP femur

A
  • Supine lying with pillow under knee
  • plinth at mid thigh height
  • face patients head
  • place webspaces over distal anterior femur
  • press down –ensure not to compress the PFJ.
34
Q

how to perform caudad of PFJ

A

o Place heel of hand over base of patella with wrist extended
o Place other hand over patella to stabilise and guide it
o Apply pressure towards the foot
o This increases knee FLEXION

35
Q

how to perform cephlad of PFJ

A

o Place heel of hand over apex of patella with extended wrist
o Place other hand over patella to guide and stabilise
o Oscillatory movement towards the patients head
o Increases knee EXTENSION

36
Q

how to perform medial transverse movement of PFJ

A

o Place both thumbs on lateral border of patella

o Oscillatory movement by pushing patella medially – use fingers to guide

37
Q

how to perform lateral transverse movement of PFJ

A

o Move to opposite side of bed to the side that is being mobilised
o Place thumbs on medial border of patella
o Move patella laterally.

38
Q

what is the benefit of transverse movement of PFJ

A

Useful for patients with anterior knee pain – generalised stiffness and pain in the PFJ
