What is the knee valgus angle?

The knee valgus angle was defined as the angle enclosed by the distal femoral anatomical axis (line AB) and the femoral mechanical axis (line AC). Significant positive correlations were found between the knee valgus angles of the right and left sides and between the knee valgus angle and age.

What is tibial inclination?

The tibial slope is described as the posterior tilt of the tibial plateau relative to the longitudinal axis of the tibia. The meticulous reconstruction of the tibial slope in knee arthroplasty is known as important factor for favourable clinical outcomes regarding flexion and extension.

What is varus and 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.

How do you measure knee valgus?

Draw a line connecting the center of the knee to the center of the ankle. 5. Measure the angle between the 2 lines. A measurement of 0°/180° implies no deformity; otherwise, the observed angle is the angle of varus or valgus present (valgus if foot is lateral, varus if foot is medial).

Is knee valgus bad?

Traditionally, knee valgus (knee cave, knock knees) has always been seen as a dangerous movement that is detrimental and should be avoided at all costs. You could walk into almost any gym and you will always hear the common cue “KNEES OUT” being thrown around always.

What is normal tibial slope?

The mean tibial posterior slope in the medial plateau was 10.7 degrees (range: 5 degrees – 15.5 degrees) in the normal knees and 9.9 degrees (range: 1.5 degrees – 19 degrees) in the varus knees.

How do you measure your tibial slope?

To measure the PTS angle, first line was drawn tangential to posterior tibial cortex, and the other perpendicular to the first line. A third line was drawn tangential to the surface of the tibial plateau. The angle between the third and the second lines was considered as posterior tibial slope, Figure 1 (10).

Is valgus normal?

At 3 to 4 years of age, a femoral-tibial angle from 2 degrees varus to 20 degrees valgus is considered normal while neutral to 12 degrees valgus is normal over the age of 7 (Hensinger, 1986; Klin, 1983; Salenius, 1975).

Can you fix valgus knee?

Strengthening the knee and hip muscles can improve valgus knee and performing a squat with a resistance band can help improve function. Valgus knee can happen when lowering or rising out of the bottom of the squat. Resistance bands are great tools to help correct valgus knees and provide strength to your hip muscles.

How do you treat valgus deformity?

It appears that varus osteotomy is an effective procedure for the treatment of osteoarthritis of the knee with valgus deformity, above all in order to alleviate pain, although the operation requires precision, and correct selection of patients is of prime importance.
