1

function of ACL

prevents anterior displacement of the tibia on the femur

2

This consists of the arcuate ligament, oblique popliteal ligament, popliteus tendon, and lateral head of the gastroc. Assists the cruciate ligaments in controlling posterolateral rotary instability

arcuate ligament complex

3

knee fat pads

quadriceps
prefemoral
infrapatellar

4

anterior knee pain when infrapatellar fat pad is impinged

Hoffa's syndrom

5

LCL origin/insertion

lateral femoral condyle to fibular head

6

MCL origin/insertion

medial femoral epicondyle to medial aspect of tibial shaft

7

Pes anserine insertions

- gracilis
- semitendinosus
- sartorius

8

plicae

- extensions of synovial membrane
- commonly found medial to the patella

no function, but can be a source of pain

9

PCL function

prevents posterior displacement of the tibia on the femur

10
