A lateral heel wedge is a small orthotic device that is placed inside the shoe on the outer edge of the heel. The wedge is typically made of a firm material, such as EVA foam or plastic, and can vary in height from 3mm to 15mm, depending on the individual patient’s needs.
The primary purpose of a lateral heel wedge is to shift the weight bearing from the medial (inner) side of the foot to the lateral (outer) side. This can help reduce the load on the medial compartment of the knee, which is often the site of pain in conditions like osteoarthritis, patellofemoral pain syndrome, or medial collateral ligament injury.
By reducing the load on the medial compartment, a lateral heel wedge can help alleviate symptoms such as pain, swelling, and instability associated with these conditions. It can also improve gait mechanics by promoting a more neutral alignment of the lower limb, which can further reduce stress on the knee joint.
However, it’s important to note that the use of a lateral heel wedge should be determined by a healthcare professional after a thorough examination and diagnosis of the underlying condition causing the medial knee pain. Additionally, proper fitting and prescription of the wedge are essential to ensure optimal results and prevent any adverse effects.
