What is valgus and varus knee?

In a varus (bow-leg) knee, this line passes medial to the center of the knee, increasing force across the medial tibiofemoral compartment. In a valgus (knock-knee) knee, the axis passes lateral to knee center, increasing force across the lateral compartment.

What is calf valgus?

Valgus knee is a lower leg deformity that exists when the bone at the knee joint is angled out and away from the body’s midline. This causes the inability for a person to touch his or her ankles while the knees touch together.

What causes varus and valgus deformity?

Osteoarthritis is the most common cause, however, other causes include post-traumatic arthritis, rheumatoid arthritis, rickets, and renal osteodystrophy. Regardless of etiology, the valgus malalignment can be corrected with careful analysis of the deformity and a systematic surgical approach.

What is the meaning of valgus knee?

A medial alignment of the femur and tibia of less than 180°.

How do you measure varus and 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).

What does valgus varus test for?

Valgus and varus stress tests of the knee – UpToDate. The valgus stress test (photo A) is used to assess the integrity of the medial collateral ligament, while the varus stress test (photo B) is used to assess the lateral collateral ligament.

What is varus deformity?

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 does the term varus mean?

Definition of varus 1 : of, relating to, or being a deformity in which an anatomical part is turned inward toward the midline of the body to an abnormal degree a varus heel. 2 : valgus sense 1 —used of the knee.

Is bow legged valgus or varus?

Pain in the hip, knee, and ankle can often be caused by bowlegs (varus deformity) or knock knees (valgus deformity). In other words, when our legs are not aligned straight at the hips, knees, and ankles, there can be an abnormal force across the knee.

What is varus thrust?

Varus thrust is the visualized dynamic bowing out of the knee laterally while the limb is weightbearing (stance) during ambulation, with the return to a less varus alignment during nonweightbearing (swing).

What is varus position of the ankle?

Ankle varus is a condition where the ankles roll out , diminishing the stability and overall alignment of the body.

What is a forefoot Varus?

Forefoot varus is when the forefoot is inverted (big toe higher than 5th toe) while the subtalor joint and calcaneus are in neutral. This foot abnormality almost always causes over pronation. Joint play is often excessive. Compensations include calcaneal eversion and navicular collapse to allow forefoot to contact the surface.
