How is genu varus measured?
The varus deformity can be quantified with the hip-knee-ankle angle (HKA), which measures the angle between the mechanical axis of the femur and the center of the ankle joint on AP, full-length, weight-bearing radiographs.
How do you measure tibiofemoral angle?
Tibiofemoral angle was measured according to the method described by Arazi et al3. Angle between the two lines was measured as tibiofemoral angle using goniometer while the children in standing position with patella pointing forward and either both knees or both ankles were just touching each other.
What is the angle of genu Valgum?
In men, the Q angle should be less than 18 degrees with the knee in extension and less than 8 degrees with the knee in 90 degrees of flexion. A typical Q angle is 12 degrees for men and 17 degrees for women.
What is the normal tibiofemoral angle?
A “normal” knee alignment has a tibiofemoral angle of approximately 5–7° valgus.
What is varus angle?
Orthopedics. A varus deformity is an excessive inward angulation (medial angulation, that is, towards the body’s midline) of the distal segment of a bone or joint. The opposite of varus is called valgus. EX: Varus deformity results in a decreased Q angle of the knee joint.
What is genu varus and valgus?
Genu varum (upper panel) is a varus alignment of the knee. In varus deformities, the apex of the angle formed by the bones on both sides of a joint points away from the body. Genu valgum (lower panel) is a valgus alignment of the knee.
What is a varus angle?
A varus deformity is an excessive inward angulation (medial angulation, that is, towards the body’s midline) of the distal segment of a bone or joint. The opposite of varus is called valgus. EX: Varus deformity results in a decreased Q angle of the knee joint.
What is physiologic genu valgum?
While physiologic knock-knee normally occurs during early childhood and spontaneously resolves by age 7, genu valgum refers to the pathologic condition that tends to develop in early adolescence and does not spontaneously resolve after age 7. Asymmetric genu valgum is more likely to be pathologic than physiologic.
What is varus vs valgus?
Whenever the distal part is more lateral, it is called valgus. Whenever the distal part is more medial, it is called varus. Therefore, when the apex of a joint points medially, the deformity, if any, would be called valgus, as the distal part points laterally.
Where is tibiofemoral joint?
Brief Anatomy of the Knee[edit | edit source] The tibiofemoral joint is where the femur meets the tibia. It includes intra-articular structures such as the menisci and cruciate ligaments (ACL and PCL) and extracapsular structure such as the collateral ligaments (MCL and LCL).
What is Q angle?
The Q angle, which is also known as quadriceps angle, is defined as the angle formed between the quadriceps muscles and the patella tendon.
Is varus medial or lateral?
It is determined by the distal part being more medial or lateral than it should be. Whenever the distal part is more lateral, it is called valgus. Whenever the distal part is more medial, it is called varus.
