Leg length discrepancy and why it commonly occurs during recovery

The recovery phase marks the start of your new normal. Changes such as new restrictions, physical limitations, and medical equipment may affect how you rest, heal, and recover. For many foot and ankle injuries or procedures, a CAM walker—also known as a walking boot—is part of the recovery. These protective devices are key during healing, but they also create a new challenge: an uneven gait due to leg length discrepancy.

How CAM walkers can alter gait mechanics

Leg length discrepancy from a CAM walker occurs when it elevates one foot higher than the other. During ambulation, the boot’s elevation and ankle-motion restrictions can alter gait mechanics by making strides uneven, shorter, or off-balanced. This can cause secondary issues, such as pain and instability while walking.

Common secondary issues

As your body tries to compensate for the uneven gait, you may experience pain or discomfort in areas beyond the injury. Common issues include hip pain from CAM walker use due to uneven hip alignment, knee and lower back discomfort from a shift in weight and misalignment caused by a leg length discrepancy, and walking boot balance problems. The pain and instability from the CAM walker can affect activities of daily living and make recovery more difficult.

Why gait symmetry and stability matter during healing

A balanced gait distributes weight evenly and helps keep your center of gravity stable while allowing your muscles and joints to work together. This natural protective mechanism decreases the risk of falling, while also preventing abnormal wear and tear on your knees, hips, and lower back. Gait symmetry and stability will allow your body to heal effectively while preventing new injuries.

Solutions that help reduce imbalance and improve mobility

Fortunately, there are solutions that help reduce imbalance and improve mobility. For minimal discrepancy or short-term CAM walker use, a supportive shoe with a thick sole or a heel lift insert can restore balance and gait symmetry. For a lasting, seamless recovery, the DARCO International Body Armor® Stirrup Walker is an ideal choice.  Utilizing patented PowerPods® technology on the outsole, this walker was designed to minimize leg-length discrepancy, matching the stack height of daily-wear athletic sneakers and creating a lower profile compared to traditional CAM walkers to promote a safe, comfortable recovery.

Awareness of leg length discrepancy and having early discussions with your healthcare provider can help reduce discomfort, improve balance, and support a smoother recovery. With the right support, you can walk comfortably and safely through recovery.
