Knee/Patella
| Question | Answer |
|---|---|
| AP Knee | - CR ½ inch below patellar apex - 5 degree angle depending on ASIS - Femoral epicondyles parallel |
| PA Knee | - CR ½ inch below patellar apex - 5 degree caudal angle - Femoral epicondyles parallel |
| Lateral Knee (mediolateral) | - CR 1 inch distal to medial epicondyle - 5 degree cephalad angle - Flex knee 20-30 degrees, femoral epicondyles perpendicular |
| Oblique Knee Medial Rotation | - CR ½ inch below patellar apex - 5 degree angle depending on ASIS - Medially rotate leg 45 degrees |
| PA Axial Intercondylar fossa - Homblad | - CR at midpopliteal crease - Knee flexed 60-70 degrees with femur higher than lower leg |
| PA Axial Intercondylar fossa - Camp coventry | - CR at mid popliteal crease - Match the angle with the lower leg (about 40-50 degrees) - Knee flexed 40-50 degrees with lower leg higher than femur in prone position |
| Intercondylar fossa - Beclere | - CR ½ inch below patellar apex - CR angled perpendicular to long axis of tibia - Flex knee 40-45 degrees |
| PA Patella | - CR midpopliteal crease - Rotate leg laterally 5 degrees to place intercondylar line parallel to IR |
| Lateral Patella | - CR mid-femoropatellar joint - Place affected side down and flex knee 5-10 degrees |
| Tangential Method Patella (Hughston) | - CR midway between femoropatellar joints - Angled approximately 45 degrees - Flex knees 50-60 degrees |
| AP Lower Leg | - CR midpoint of leg - Include both ankle and knee joint |
| Oblique Lower Leg (medial rotation) | - CR midpoint of leg - Rotate femur, knee, and leg medially 45 degrees and dorsiflex foot - Include both ankle and knee joint |
| Lateral Lower Leg | - CR midpoint of leg - Affected side down, include both ankle and knee joint |
