THE BIOMECHANICS OF THE HUMAN
LOWER ERXTRIMITY
D R A L I YA P T
D P T OM P T ( II R S )
L E C : B U M HS , Q T A
Normal Q Angle
Values:
•Men: 10–15°
•Women: 15–20°
(due to wider pelvis)
Abnormally Low Q Angle (<10°):
 A reduced or lower-than-normal Q angle is less commonly discussed than a high Q
angle but can still cause issues.
 Possible Causes:
 Genu varum (bow legs)
 Tight lateral knee structures
 Overdeveloped medial quadriceps
 Congenital alignment abnormalities
Clinical Implications:
 Increased stress on the lateral side of the knee
 Patellar tracking issues (may track medially)
 Medial knee pain
 Increased risk of medial meniscus strain or osteoarthritis
