What is the expected Q-angle for a normal male?

The Q-angle, or quadriceps angle, is an important measurement in assessing the alignment of the knee joint. It is formed by the intersection of two lines: one extending from the anterior superior iliac spine (ASIS) to the midpoint of the patella and another extending from the midpoint of the patella to the tibial tuberosity.

For a normal male, the expected Q-angle ranges from 10 to 15 degrees, with an average around 15 degrees. Therefore, the value of 13 degrees mentioned aligns well with standard measurements for males. This is important in clinical practice as deviations from this range can indicate issues such as patellar tracking problems or predispositions to injury.

A typical value of 13 degrees falls within the average expected for males, reflecting normal anatomical alignment and indicating a decreased likelihood of knee-related issues associated with abnormal angles. Understanding the Q-angle is crucial for physical therapists in evaluating and diagnosing musculoskeletal conditions, as well as in creating appropriate treatment plans.
