1

Avulsion fractures at the hip or pelvis are usually treated how>

Non-operably

2

Most common casue of a pelvic avulsion fracture?

-strong muscular contraction during sports activities in skeletally immature patients

3

Most common pelvic avulsion fracture sites?

ASIS (anterior superior illiac spine), AIIS, IT (Ischial tuberosity

4

Hip Laberal tear symptoms

Groin Pain, clicking and snapping of hip joint, limited range of motion of hip joint

5

THree types of femeroacetabular impingement

CAM, Pincer, Combined

6

Quadriceps and Hamstring tears?

Once you've had one you are prone to more because the muscle heals with scar tissue and not muscular tissue. Scar tissue is not as flexible

7

New treatment method for hamstring and quad tears?

Platelett rich plasma,,,plateletts have healing factors and growth factors which help with healing

8

Meniscus repair options>

non-operative, repair, remove (used to be done all the time) With arthroscopic surgery we can now do some repairs.

9

Anterior Cruciate Ligament causes

Deceleration, cutting, jumping

10

70% of ACL tera patients....

hear or feel a pop.
-often say they felt like their knee was being hyperextended
-walking is difficult
- knee swells within hours

11

What is the difference between the swelling time with ACL and meniscus

ACL swells within hours,
Meniscus take a few days
THis is because tendons have vasculature (ACL bleeds and you get hemiarthrosis.

12

women have increased risk of ACL injury

yes, why? muscle strength, hormonal influences, limb alignment, notch dimensions, ligament size

13

What is the most sensitive ACL test?

Lachman test- looks like the anterior drawer test, feel for end mark.

14

Most accurate radiological study for ACL tear

MRI, non-orthogonal plane with the knee externally rotated 15 degrees, identify associated meniscal/chondral injuries, collateral ligaments

15

Characteristic bone bruise pattern of ACL

Lateral Femoral Condyle (mid third) and post 1/3 of lateral tibial plateau....very sensitive...know

16

PCL tear cause?

Direct blow to the shin (tibia), fall on flexed knee, hyperextension

17

PCL tear signs

posterior sag

18

PCL injury treatment

non-operative: immobilize, rehab
arthroscopic reconstruction (surgery is not great)

19

Long term risk of PCL injury not being repaired?

arthritis

20

MCL/ LCL treatment?

Often non-operative

21

WHy should you be aware of knee dislocations

highincidence of neurovascular injury

22

definition of a knee dislocation

3 out of 4 ligaments torn

23

common cause of knee dislocation

high velocity fall (over 5 feet and MVA), low velocity ( falls under 5 feet), ultra low velocity Obesity

24

Most common nerve injury in knee dislocation

Peroneal, half result in permanent neurological defect,

25

Popliteal artery injury in knee dislocation can lead to amputation if not repaired in under 8 hours

true. know

26

What is one structral feature that can pre-dispose to patella injury

patella alta, patellar tendon is just a little too long

27

OCD of the knee usuallu occurs where

lateral wall of the medial chondyle

28

Cause of OCD injury of the knee

Vascular, traumatic, genetic

29

Most common ankle sprain?

Inversion, sprain of the lateral ligaments

30

Syndesmosis

high sprain...anterior ligaments that hold tibia to fibula
