A plantarflexion stop is beneficial in controlling genu recurvatum of what degree?

A plantarflexion stop is specifically designed to limit the motion of the ankle joint, promoting better alignment and reducing issues associated with overextension of the knee, such as genu recurvatum. Genu recurvatum is often characterized by an excessive hyperextension of the knee and can lead to instability and discomfort.

When addressing genu recurvatum, a plantarflexion stop is most effective for cases that are acute or moderate in nature, which typically means those with less than 20 degrees of hyperextension. This limitation allows for better control of the knee joint position during ambulation or functional movements, thereby improving overall stability and function.

In cases where hyperextension is over 20 degrees, alternative strategies may need to be considered, as the severity could suggest more significant neuromuscular or structural issues that a simple plantarflexion stop may not adequately address. Thus, the application of a plantarflexion stop for genu recurvatum is particularly suitable when the degree of hyperextension is less than 20 degrees.
