1

MCL attachments

deep- thickens joint capsule, attaches to medial menses

superficial- band that runs from bellow adductor tubercle inderioanterior deep to pes anserine tendons

2

LCL attachments

doesn’t attach to joint capsule
runs from femoral epicondyle to head of fib

3

ACL attachments/ what does it protect against

anterior medial intercondyler eminence of tibia traveling posterior to lateral femoral condyle

stabilizes against- Anterior translation of tin., hyperextension

4

PCL attachments

posterior aspect of tibia traveling superiorly and anterior to medial condyle

restrains posterior displacement

5

Menisci characteristics and functions

characteristics: wedge shaped, thicker on outside than in
: only vascularized on outside\

Function: deepens articulation, increased lunercation, joint stability

6

MCL MOI, Test

MOi- blow to lateral aspect of knee(valgus)
-associated w joint capsule/ meniscus injury

Test- Stress test at 0 and 25 degrees feeling for gapping/ pain

7

LCL MOI, Test

MOI- Varus Stress

Test- Varus stress test- springy end feel

8

ACL MOI, SS, Test

MOI- hyperextension/ rotation of knee

SS- hearing POP, immediate loss of function, swelling

Test- Lachmans, Anterior drawer test

9

PCL MOI, SS, Test

MOI-hyperextention/blow to anterior tibia
SS- not many at time of injury

Test- Posterior drawer test

10

Menisci Tears MOI, SS, Test

MOI- rotation and flexion of knee impinging menisci

SS- locking, clicking, pain along joint, knee gives out

Test- Thessaly test

11

4 types of menisci tears

longitudinal- twisting motion w foot fixed/ knee flexed

Bucket handle- like longitudinal but medial segment displaced toward centre

Horizontal- degeneration, sheers from rotation

Parrot beak- 2 tears

12

IT band friction Syndrome MOI, TEST

MOI- can come from varus knees, over pronation w walking, lateral IT band rubs on lateral femoral epi.

Test- flex and extend knee and put pressure on IT band

13

Knee Osteoarthritis MOI,SS

MOI- Progressive degeneration of cartilage

SS- causes joint stiffness, decreased ROM, strength, function

women more sussptible/ post ACL patients

14

Patella Femoral Pain Syndrome (PFPS) MOI, SS

MOI- can be due to pronation in foot, weakness in hip, value knees, tight IT, VMO atrophy

SS- gradual onset, pain w/ descending stairs, sitting, can hear/feel pops clicks due to IT getting caught

15

Petella dislocation/ Sublux MOI,

laxity in retinaculum
most often when knee at 30 degrees of flex and lateral blow

16

Patellar Tendinopathy MOI, SS

MOI- repetitive movements of misaligned quads
SS- severe pain w palpation of tendon + resisted knee extension

17

Things that affect Patella tracking

Tight IT and lateral retinaculum
lax medial patellar retinaculum
weak quads
patella shape/position

18

Chondromalacia MOI, SS, Test

MOI- Due to abnormal excursion and compressive force
- degeneration in articular cartilage

SS- Localized pain, tenderness

Tests- Compression test, clarcks tests weldron test

19

Reasons for anterior knee pain (prox and distal segment)

prox-back- excessive lordosis/kuphosis, lateral pelvic tilt
-hip- tight hip flexor, ham, adductor, imballance

dist.-tibia- excessive tibial torsion
-foot- tight chillies, weak inverter,/everter

20

Patella Plica syndrome SS, Test

SS- gradual onset of pain, pain w prolonged sitting, pain w first 10 steps

Tests- Medial synovial plica+stutter test

21

Osgood Shlatter MOI SS

MOI- Inflammation or partial evulsion of tibial apophysis

SS- tibial tubercle as source of pain, tubercle is enlarged

22

Sinding-larsen-johnson disease MOI, SS

MOI- inflammation of partial avulsion of apex of patella
SS- gradual onset, pain w palpation of inferior patellar w leg extended

23

Patella tendon Autograft or Hamstring tendon Autograft

HT- better, favoured w high level sports, better if sports have u on knees, less anterior knee pain, osteoarthritis, pain w kneeling, pain post surgery.

only slight decrease in hamstring strength
