A

Prevents hyperextension (arcuate and oblique popliteal ligaments)

17
Q

ACL

A

Prevents anterior translation of tibia and hyperextension

18
Q

PCL

A

Prevents posterior translation of tibia and hyperflexion

19
Q

MCL

A

Resists Valgus Force; attached to medial meniscus

20
Q

LCL

A

Resists Varus forces; does not attach to lateral meniscus

21
Q

Patellar Retinacula

A

Thin connective tissue that provides stability to patellofemoral joint

22
Q

Muscles that extend the knee

A

Quads- all innervated by femoral nerve

23
Q

Muscles that flex the knee

A

Hamstrings (tibial nerve), gracilis (obturator nerve), and popliteus

24
Q

Screw Home mechanism

popliteus unlocks knee
medial rotation of tibia locks

25

Continuation of joint cavity between distal femur and quadriceps

26
Q

Prepatellar Bursa

A

Subcutaneous, anterior to patella

27
Q

Infrapatellar bursa

A

both sides of the patellar ligament

28
Q
