A

chondromalacia patellae and/or patella tendonitis

18
Q

Patellafemoral pain syndrome - DONT USE

A

quadriceps sets, single leg raise flexion, and isolated quad exercises for patellofemoral pain

19

Patellar tendonosis/tendonopathy (jumpers knee) - degeneration of ____
May be related to

A

patellar tendon
May be related to overload and/or jumping
Might be itnerrelated to patellofemoral dysfunction

20
Q

Pes anserine bursitis - typically caused by

A

overuse or a contusion

21
Q

Fractures - Femoral condyle - what is most often invovled

A

medial femoral condyle is most often involved because of anatomical design

22
Q

Fractures - femoral condyle - common MOI

A

fall with knee subjected to shearing force

23
Q

Fractures - tibial plateau - common MOI

A

combination of valgum and compression forces to knee when knee is in a flexed position

24
Q

Fractures - tibial plateau - often occurs in conjunction with

A

medial collateral ligamentous injury

25
Q

Fractures - epiphyseal plate - MOI

A

WB torsional stress

Presents more frequently in adolescents (would be ACL injury in adults)

26
Q

Fractures - patella - MOI
