Tibiofemoral Joint
● Collaterals
○ MCL
○ LCL
● Patellofemoral angle
● Angle formed between
the quadriceps muscle
and the patellar tendon
Q-angle
● Normal Q-angle

● Normal Q-angle
○ Male - 13°
○ Female - 18°
● SPL from medial tibial plateau to
lateral femoral condyle
● Weakest ligament of knee
● Prevents: anterior translation of
the tibia on the femur
● MOI: hyperextension, rotation
