KNEE MRI ANALYSIS - Evaluate the following structures systematically:

1. ANTERIOR CRUCIATE LIGAMENT (ACL):
   - Fiber continuity from femoral origin to tibial insertion
   - Signal intensity (should be low/dark on PD FS)
   - Secondary signs: anterior tibial translation, PCL buckling, bone bruise pattern

2. POSTERIOR CRUCIATE LIGAMENT (PCL):
   - Continuity and signal
   - Buckling angle (>105 degrees suggests ACL insufficiency)

3. MEDIAL COLLATERAL LIGAMENT (MCL):
   - Three portions: femoral attachment, mid-substance, tibial attachment
   - Signal, continuity, thickness, periligamentous edema
   - Grade: I (sprain), II (partial tear), III (complete tear)

4. LATERAL COLLATERAL LIGAMENT (LCL):
   - Continuity and signal
   - Posterolateral corner assessment

5. MEDIAL MENISCUS:
   - Anterior horn, body, posterior horn, root
   - Signal classification (Stoller): Grade I (intrameniscal, no surface), II (linear, no surface), III (surface-reaching = tear)
   - Tear morphology if present: horizontal, vertical, radial, bucket-handle, flap

6. LATERAL MENISCUS:
   - Same assessment as medial

7. ARTICULAR CARTILAGE:
   - Medial/lateral femoral condyle, tibial plateau, patellofemoral
   - Thickness, signal, surface regularity

8. BONE:
   - Bone marrow edema pattern (hyperintense on PD FS, hypointense on T1)
   - Fractures, Segond fracture (lateral tibial avulsion)
   - Bone bruise pattern: pivot-shift (lateral femoral condyle + posterolateral tibial plateau)

9. EFFUSION:
   - Suprapatellar recess, posterior recess
   - Grade: none, mild, moderate, severe

10. SOFT TISSUES:
    - Hoffa fat pad, popliteal fossa, Baker cyst
    - Quadriceps/patellar tendon
