Knee Flashcards
Examples of Knee Pathology
- PFPS
- Patellar Tendinopathy
- ITB Syndrome
- Knee OA
- ACL
PFPS
- patellofemoral pain syndrome
- most common complaint in runners
- repetitive overload
PFPS Influences
- local (mal-tracking)
- proximal
- distal
PFPS: Local Influence
- mal patellar tracking
- patellar tilt that compresses lateral patella
- delayed activation of VMO
PFPS Treatment
Local
- VMO/biofeedback
- Straight leg raising-hip adductors (leg in ER)
- limited squatting–>full squat
- patellar taping (short term)
- stretch IT band
Normal Patellar Tracking
- with knee in flexion patella is lateral
- as knee extends patella tracks medial then laterally
- should not tilt
PFPS:
Proximal Influence
- hip affects knee
- dynamic Q-Angle
- weak abd/ER Mm allowing femur to IR and increase Q-angle–>more stress on patella
PFPS:
Distal Influence
-Overpronation of the foot causes tibial/femur IR and knee valgus–>increased stress on patella
Foot Orthotics with PFPS
-has some research to support decreased pain
Tendinitis
- inflmmatory
- warm to touch
- Ice, NSAIDs
Tendinosis
- Collagen degeneration
- chronic
- exercise, (eccentrics)
Mechanism of patellar tendinopathy
- weak quads
- overuse of tendon (dominant quads, glut max weak)
Quad dominant
-in squat knees go way past feet
Glut max dominant
-in squat, sit back with knees behind toes
Work quad more on:
-down sloped wedge
work glut max more on:
-flat surface
Plyometrics:
- forward hops
- bounding
- step hops
cho-pat strap
- brace for knee (PFPS)
- decrease tendon strain
ITB Syndrome
- Iliotibial band syndrome
- pain 1-2” above joint line, lateral side
- 2nd cause of knee pain
Nobles Compression Test
-ITB Syndrome test
Function of ITB
-decelerate IR or tibia
Insertion of ITB
- patella
- Gerdy’s tubercle
- Fibular head
Impingement Zone
- 20-30* flexion
- ITB more taut and causes pain on fat pad under ITB
Biomechanical factors of ITB Syndrome
- prominent LFC (lateral femoral condyle)
- weak hip abductors
- ITB tightness
- Genu varum
