A knee brace with a medial metal insert is designed to prevent which type of force?

Varus
Valgus
Sheer
Rotational

The correct answer is: Valgus

A knee brace with a medial metal insert is specifically designed to counteract valgus forces. Valgus forces occur when a force is applied to the lateral aspect of the knee, causing the joint to move inward towards the midline of the body. This movement can place undue stress on the medial structures of the knee, including the ligaments and cartilage. By incorporating a medial metal insert, the brace provides additional stability and support on the inside (medial side) of the knee. This support helps to prevent excessive inward movement that can result from valgus stress, thus reducing the risk of injury or exacerbation of existing conditions such as ligamentous tears. Understanding the mechanics of knee braces and the forces they are designed to combat is key for athletic trainers and healthcare professionals in protecting athletes and patients during physical activities.
