What is the angle indication for a varus deformity at the knee joint?

• A. More than 185 degrees
• B. Less than 175 degrees
• C. Between 180 and 185 degrees
• D. Exactly 175 degrees

Answer: (B)

A varus deformity at the knee joint is characterized by an inward angulation of the knee, often referred to as "bow-leggedness." This condition affects the alignment of the knee and can alter the loading patterns across the joint during weight-bearing activities. The measurement in question involves the angle formed between the femur and the tibia. In a healthy knee, this angle typically ranges around 180 degrees, which indicates proper alignment. When measuring for varus deformity, the angle decreases as the inward angulation of the knee becomes more pronounced. If the angle is less than 175 degrees, it signifies a significant varus deformity where the knee is in a more pronounced inward position compared to normal. Therefore, the correct answer accurately reflects that a varus deformity at the knee joint indicates an angle of less than 175 degrees, highlighting the misalignment and the degree of inward bowing present in the condition.
