? Accessory Medial Meniscofemoral Ligament

Posterior capsular tears

Scenario: Hyperextension, "pop", intact cruciates, posterior capsular tear

Tibial Tunnel Cyst post ACL Recon (II)

Pearls from Stoller Macau April 2011 - 3. Knee

1. Trochlear groove - assess on sag.
2. Meniscofemoral and meniscotibial (coronary) recesses.
3. Horizontal tear - must extend to apex (sag).
4. Flap tear - one type that looks horizontal but extends short of apex creating small inferior leaf.
5. Flap tear -- vertical configuration, but inner 1/3 (sag).
6. Vertical/longitudinal tear - outer 1/3 (sag).
7.  Menisco-capsular separation -- two scenarios
• ACL with tear of periph of post. horn lat. meniscus (fluid betw. capsule and periph. of post. horn).
• MCL tear with meniscotibial lig. tear.
8.  Posterolat. corner -- review on sag and axial.
9. SONK -- almost all cases are probably insufficiency fractures
10. CMP - MRI adaptation of Outerbridge classification; describe rather than classify; ICRS classification.
11. MPFL - slice above proximal origin of MCL, tears at femur
12. Patella tendinosis - best on GRE.
