Q

What do you inspect the knees for?

A

With patient standing

1)bony allignment

  • valgus, varus or hyperextension deformity
  • line drawn from iliac crest to middle toe

2)Swelling or masses

3)Gait

4)squatting and assessing patellofemoral compartment –> crepitus…

with patient sitting

1)patellar tracking

2)prominence of the tibial tuberosity

with patient lying

1)assymetry between knees

2)masses

3)Scars/ lesions

4)muscle atrophy and hypertrophy

Q

What do you palpate the knees for?

A

1)Temperature above and below the patella

2)Tenderness

  • joint line
  • collateral ligaments (MCL, LCL)
  • patellar edges
  • pre-patellar bursa and suprapatellar bursa
  • pes anserine bursa

3)Crepitation

4)Effusion

bulge sign–>best for small effusions

–> milk medially and sweep down lateral

Ballotement–> best for large effusions

–> press down on suprapatellar pouch and then try to move fluid around

Patellar tap-

–> milk fluid into suprapatellar pouch and then press down of pattella –> listen for clunk

Q

How do you test the ligaments, meniscus and patella?

A

ligaments

1) MCL–> create valgus deformity
2) LCL–> create varus deformity
3) ACL –> anterior drawer test

–> lachmans test with knee fixed in 20-30 degrees of flexion

4)PCL–>posterior drawer test

meniscus’s

McMurrays test for medial meniscus–> fingers on medial joint line, valgus deformity ( ankle inward) + internal rotation

McMurrays test for lateral meniscus–> fingers on lateral joint line, varus deformity (ankly outward + external rotation)

Thessaly test
