Q

PFPS: Local Influence

A
  • mal patellar tracking

Q

PFPS Treatment

Local

A
  • VMO/biofeedback
  • Straight leg raising-hip adductors (leg in ER)
  • limited squatting–>full squat
  • patellar taping (short term)
  • stretch IT band

Q

Normal Patellar Tracking

A
  • with knee in flexion patella is lateral
  • as knee extends patella tracks medial then laterally
  • should not tilt

Q

PFPS:

Proximal Influence

A
  • hip affects knee
  • dynamic Q-Angle
  • weak abd/ER Mm allowing femur to IR and increase Q-angle–>more stress on patella

Q

PFPS:

Distal Influence

A

-Overpronation of the foot causes tibial/femur IR and knee valgus–>increased stress on patella

Q

Plyometrics:

Study These Flashcards
A
  • forward hops
  • bounding
  • step hops
18
Q

cho-pat strap

Study These Flashcards
A
  • brace for knee (PFPS)

- decrease tendon strain

19
Q

ITB Syndrome

Study These Flashcards
A
  • Iliotibial band syndrome
  • pain 1-2” above joint line, lateral side
  • 2nd cause of knee pain
20
Q

Nobles Compression Test

Study These Flashcards
A

-ITB Syndrome test

21
Q

Function of ITB

Study These Flashcards
A

-decelerate IR or tibia

22
Q

Insertion of ITB

Study These Flashcards
A
  • patella
  • Gerdy’s tubercle
  • Fibular head
23
Q

Impingement Zone

Study These Flashcards
A
  • 20-30* flexion

- ITB more taut and causes pain on fat pad under ITB

24
Q

Biomechanical factors of ITB Syndrome

Study These Flashcards
A
  • prominent LFC (lateral femoral condyle)
  • weak hip abductors
  • ITB tightness
  • Genu varum
25
Treatment for ITB Syndrome
- strengthen (glud med, hip ER) - joint mob (sup tib-fib) - Foam Roller - cho-pat bracing - Surgery: cut ITB and shave down lateral epicondyle
26
ITB Syndrome & Running
- avoid running down hill | - avoid banked surface (valgus knee)
27
Diagnosing OA
- knee pain plus 3 of following: - -age>50 - -AM stiffness <30 min - -Crepitus - -bony tenderness - -no palpable warmth - -osteophytes on x-ray
28
Risk Factors of OA
- age - female - obesity - previous injury (ACL, Meniscus) - Mm Weakness
29
Stage I for OA Rehab
- joint mobs (distraction, ant/pos, rotational) - strengthen around knee - weight reduction - canes, unloader braces, orthotic wedging
30
TKA Rehab
- Quad strengthening - Eccentric Stepper - NMES with Quad Ex's
31
Eccentric Stepper
- 5-20 min sessions - 4 weeks - increase intensity over 12weeks
32
NMES Quads
- 2-3 weeks post surgery - 3x/week - 6 weeks - open and closed chain
33
ACL Prevention: | 3 Phases
- Technique Development - Fundamental - Performance
34
ACL Prevention Program
- 15-25 min warm up routine - 3x/week - warm up, stretch, strengthen, plyometrics, agility
35
Stage II Knee OA Rehab
Hip strengthening
36
Stage III Knee OA Rehab
Aerobic Exercise
37
Treatment of Knee OA
- manual therapy - open vs closed chain ex's - weight loss - AD (cane, unloader brace, orthotic wedging) - cycling - aquatics
38
Medical Management of Knee OA
-total joint arthroplasty (TKA)
39
UCA
- unicompartmental arthroplasty | - only replace the side that you need
40
Activities Allowed After TKA
- low impact aerobics - stationary cycling - bowling - golf - dancing - horseback riding - swimming - walking
41
Activities Allowed if You've Done them before (after TKA)
- road cycling - canoeing - hiking - rowing - cross-country skiing - nordic track skiing - speed walking - tennis - ice skating
42
Activities Not Recommended after TKA
- racquetball/squash/handball - soccer - single tennis - volleyball - basketball - jogging
