What is a common consequence of improper fitting of a KAFO on the thigh area?

When a KAFO (Knee-Ankle-Foot Orthosis) is improperly fitted around the thigh area, one common consequence is anterior thigh pressure. This situation can occur if the orthosis is too tight or if it is positioned incorrectly. The design of a KAFO is such that it provides support and stabilization to the knee and ankle while allowing for some functional movement. When there is excessive pressure on the anterior thigh, it can lead to discomfort and potentially inhibit the patient's mobility.

The presence of anterior thigh pressure may limit the patient’s range of motion at the knee joint and can also cause skin irritation or even skin breakdown in severe cases. This makes it essential for clinicians to ensure that the KAFO fits properly, allowing for optimal alignment and function while minimizing any areas of excessive pressure.

In other scenarios, while issues like pain over the knee, excessive calf muscle activation, and difficulty in ambulation may arise due to various factors related to the KAFO, the specific concern regarding anterior thigh pressure highlights a critical aspect of fitting and patient comfort that must be addressed to ensure proper use of the device.
