Presentations:
RetroPatellar-vague, double clicking, catching sharp pain with crepitus.
Aggravated by sitting walking, running, riding a bike or going upstairs
May cause patellar dislocation

Question 2

Osgood schlatters

Answer 2

Avulsion of the tibial tuberosity with secondary ossification
More common and athletic adolescent boys, 12 to 18 Yo
Due to micro trauma and stress of the tibial tuberosity
Presentations :
Painful bump, and the tibial tuberosity and is worsen with activity
Maybe mild local, swelling and palpable tenderness, and in severe cases, atrophy and weakness of the quad .

Question 3

Osteochondritis dissecans

Answer 3

presentation:
Necrotic fragment, that may be loose and become a joint mice
Clicking and crepitus
Wilson’s test is used to identify

Question 4

Meniscal tear

Answer 4

Lateral-hyperextension grinds on lateral mesniscus
Medial- flexion and rotation catch the medial meniscus
Presentation:
Pain
Slow, synovial, swelling
Locking and simultaneously unlocking

MC IN women
Commonly due to compression trauma and kneeling

Question 8

May cause fibrosis of knee causing stiffness or synovitis
Knee gives away and catches
Stabbing px
