Term
| Name structural causes of Malaligment and Patellofemoral Pain Syndrome |
|
Definition
PFPS
Causes → structural
> LLD/long leg discrepancy
> shallow trochlear groove |
|
|
Term
| Name muscles and connective tissue involved in Malaligment and Patellofemoral Pain Syndrome |
|
Definition
PFPS
Causes → Muscle weakness/fascial laxity
> weak/inhibited VMO and/or inadequate timing (*VMO vs vastus lateralis)
> weak hip abductor (ie: glut med post fibres)
* vmo & vm work together to pull patella) |

|
Term
| Explain what happens to the IT band and the tight lateral patellar retinaculum with Malaligment and Patellofemoral Pain Syndrome? What happens on the ankle? |
|
Definition
PFPS
Impairments → IT band, lateral patellar retinaculum
> IT band tightens
> lateral patellar retinaculum tightens
> ankle: ankle dorsiflexes d/t tight plantarflexors
* makes tibia med. rotate & ↑ lateral force on patellofemoral jt* |
