What is the maximum acceptable Q-angle in females for optimal knee function?

• A. 13 degrees
• B. 18 degrees
• C. 20 degrees
• D. 25 degrees

Answer: (B)

The maximum acceptable Q-angle in females for optimal knee function is typically recognized to be around 18 degrees. The Q-angle is the angle formed by the intersection of the quadriceps muscle and the patellar tendon. A normal Q-angle is important for proper alignment and tracking of the patella during knee movements. When the Q-angle exceeds 18 degrees, it can increase the risk of misalignment and strain on the knee joint, potentially leading to issues such as patellofemoral pain syndrome.

In females, anatomical factors such as a wider pelvis may contribute to a larger Q-angle compared to males. Therefore, maintaining the Q-angle at or below the 18-degree threshold is essential for ensuring optimal knee function and stability during physical activities.
