1

clinical significance of the tibial tuberosity

- Osgood-Schlatter disease
- site where they harvest the bone plug for a BTB ACL repair

2

Osgood-Schlatter disease

tibial tuberosity apophysitis

3

What pathology affects the inferior pole of the patella?

Sinding-Larsen-Johansson Syndrome

4

What is Sinding-Larsen-Johansson Syndrome?

apophysitis of the inferior pole of the patella

5

clinical significance for the anterior surface of the patella

- may be a divot on the patella if there's been a bone plug harvest for a BTB surgery
- patellar fracture

6

clinical significance of the superior pole of the patella

- not much going on here
- potential chondral problem

7

What may be a cause of a patellar fracture?

- falls
- structural weakness after BTB graft is removed

8

How many layers of palpable structures under the patella?

8

9

significance of pain over lateral superior border of patella

could be a bipartite patella

10

types of bipartite patella

- true bipartite
- fracture-type bipartite

11

true bipartite

physis doesn't close

12

fracture type bipartite

due to fracture

13

clinical significance of the inferior aspect of the medial trochlear ridge

most common site of OCD due to AVN of the femur/knee

14

How do you know if you're on the inferior aspect of the medial trochlear ridge?

- flex IP joint
- thumb on inferior aspect of medial femoral condyle

15

clinical significance of the inferior aspect of the lateral trochlear ridge

- DJD/OA
- no other specific pathology that occurs here

16

function of the trochlear groove

bony buttress to prevent lateralization of the patella

17

What may cause OCD?

- with dislocation or subluxation
- may get OCD from inferior surface of patella or lateral trochlea

18

superior aspect of medial trochlear ridge clinical significance

site where the patella tracks

19

Can you palpate the superior aspect of medial trochlear ridge?

no, it's under the VMO

20

clinical significance of the superior aspect of lateral trochlear ridge

- 90% of dislocations happen laterally
- knocks off a piece of lateral trochlea
- may get an OCD lesion

21

How do you feel the superior aspect of the lateral trochlear ridge?

- above superior pole of the patella
- prominent

22

clinical significance of the trochlear groove

- where the patella tracks
- site of arthritic changes

23

palpation of the trochlear groove

- can't feel because the quad tendons are in the way
- between medial and lateral trochlear ridge
