- PEx: P.O.P along m.; pain w/ flexion, adduction, internal rotation; may hold leg in ext rotated pos., esp. if in spasm; may have Trendelenburg gait
9
Q
Iliopsoas Tendonitis/Bursitis
A
- Snapping Hip Syndrome
- MOI: acute trauma; overuse from repetitive hip flexion
- Hx: groin pain worse w/ activity; “snapping” w/ hip flexion
- PEx: pain w/ resisted hip flexion; P.O.P over pubic ramus, lateral to neurovascular bundle
- Tx: steroids (usually oral); NSAIDs; modify activty; strength/stretch exercises; e-stim
10
Q
Avulsion Hip Fractures (General)
A
- Rapidly growing males w/ mm. stronger than growth plates
- Ballistic loading w/ eccentric contracture
- D/Dx: muscle strain or contusion
- Dx: radiographs
- Tx: PRICE; crutches; stretch/strengthening after 2 weeks; return to activity w/ return of strength & function
11
Q
O’ Donahue’s Triad
A
- ACL
- MCL
- Medial Meniscus
12
Q
ACL Injury
A
- Limits ant. tibial displacement and int. rotation
- Female>Male; teens, 20s; sports
- MoI: cutting-deceleration-hyperextension (stop & turn in); most non-contact
- 60% have O’Donahue’s Triad; 50% have subchondral bone injury
- Hx: effusion & tenderness (near patellar tendon); decreased stability
- Complications: DJD; decreased stability increases reinjury; long rehab w/ surgery
13
Q
Anterior Drawer Sign
A
- For Dx of ACL injury
- supine; knee @ 90 flex; grab leg at prox tibia and pull towards you
- 50% false negative
14
Q
Lachmann’s Test
A
- For Dx of ACL Injury
- supine; knee @ 15 flex; grab leg at prox tibia and pull towards you
- can standardize w/ machine; >3mm
- 5-10% false negative
15
Q
PCL Injury
A
- Limits post. tibial displacement and ext. rotation
- Less common than ACL; auto accidents #1 cause; sports due to direct blow to prox tibia or hyperextension
- Hx: might have “pop;” no edema until 48 hrs; may WB; reluctant to extend knee
- PEx: popliteal tenderness; stability (much more than ACL injury)
16
Q
Sag Test
A
- For Dx of PCL injury
- supine; thighs @ 90 flex, knees @ 90 flex; support at ankle
- sag at tibial plateau sinks below patella –> +
17
Q
Posterior Drawer Sign
A
- For Dx of PCL injury
2. supine; knee @ 90 flex; grab leg at prox tibia and push away from you
18
Q
MCL Injury
A
- deep layer is thickened capsule; major medial stabilizer
- football & skiing; involve blow laterally
- Hx: very painful increase over time; feel/hear “pop;” knee stiffens up w/in hrs; partial tear more painful
- PEx: medial edema/minimal effusion; medial ecchymosis after 24hrs; medial instability when stressed @ 20 flex
- DDx: epiphyseal fracture (peds)
- Tx: I&II-knee brace hinged w/ locked pos.; III-cast immobilization of primary repair
19
Q
MCL Injury Grades

- medial instability when stressed @ 20 flex
- Grade I - no opening at medial joint
- Grade II - opens w/ firm end point
- Grade III - opens w/ soft end point
20
Q
LCL Injury
A
- very rare
- from major trauma with knee dislocation
- major vascular injury; cruciate & common fib n. damaged
21
Q
Meniscus Injury
A
- fibrocartilage; redistributes pressure
- MoI: WB injury; medial-involving cutting; lateral-involving rotation while squatting
- Hx: “snap or pop;” may lock right away
- PEx: medial or lateral joint line; meniscal impingement tests
22
Q

- pain w/ audible/palpable click –> +
25
