Normal anatomic angle

Normal anatomic angle

Leg

• long axis of femur and tibia: 7ºvalgus.
• center of femur head to tibial plafond: 7ºvalgus
• ASIS-patellar midline & patellar midline-tibial tubercle(Q angle): 14º(male), 17º(female)

knee

• Posterior slope of tibial plateau: 10~15(or 0~18), contribute to AP stability of knee joint

Patella

• congruence angle(most inferior point of patellar ridge and sulcus to line bisecting sulcus angle(axial. 145) -6~+6
• Lateral PF angle(intercondylar line-lateral facet line): >0

foot

• hallux valgus: <15
