What is a common measurement for a custom-fitted knee brace?

A common measurement for a custom-fitted knee brace is thigh circumference. This measurement is essential because it helps ensure the proper fit of the brace around the thigh, which is crucial for stability and comfort during movement. A well-fitted brace must accommodate the dimensions of the patient's anatomy to provide adequate support for the knee joint, particularly if the brace is designed to restrict motion or provide compression.

Thigh circumference is often taken at a specific point above the knee to ensure that the brace can effectively transfer forces without slipping during activity. Proper thigh measurement allows the orthotic fitter to select the right brace size and configuration, crucial for the effectiveness of the device and the comfort of the user.

While knee flexion angle, calf circumference, and length from ASIS (anterior superior iliac spine) to patella are important measurements in certain contexts, they do not carry the same level of significance for the initial fitting of a knee brace as thigh circumference does. The primary purpose of measuring thigh circumference is to achieve an accurate initial fit, which is fundamental to the brace's function.
