Correcting a leg length discrepancy (LLD) becomes important when there is a noticeable difference between the lengths of the legs. This difference can be small or significant and is most often seen in the lower limbs. When left unaddressed, a leg length discrepancy can contribute to discomfort, changes in gait, and ongoing joint or back pain.

At Lilburn Shoe-Buddy’s Custom Shoe Lifts, we regularly help people who are looking for a simple, non-surgical way to correct leg length differences and improve daily comfort.

What Is a Leg Length Discrepancy?

A leg length discrepancy occurs when one leg is shorter than the other. This can be caused by:

• Natural bone growth differences

• Injury or trauma

• Hip or knee replacement surgery

• Joint or muscular conditions

Some people can compensate for a short time without noticing symptoms. Over time, however, even a small difference can place added stress on the hips, knees, lower back, and spine.

Common Signs and Symptoms

People with an untreated leg length discrepancy may experience:

• Lower back pain

• Hip or knee discomfort

• Uneven shoe wear

• Fatigue while walking or standing

• Changes in posture or gait

Many individuals unknowingly compensate by walking on the toes of the shorter leg or bending the knee of the longer leg, which can lead to additional strain and joint issues.

How Is a Leg Length Discrepancy Diagnosed?

A leg length discrepancy is often identified during childhood as walking patterns develop or during routine medical evaluations such as scoliosis screenings.

To diagnose LLD, a doctor may:

• Observe posture and walking patterns

• Use blocks under the shorter leg to level the hips

• Order imaging such as X-rays or CT scans to measure bone length

Once diagnosed, treatment options can be discussed based on the amount of discrepancy and the patient’s lifestyle.

Non-Surgical Treatment: Custom Shoe Lifts

For many people, custom shoe lifts are the most practical and effective solution for correcting a leg length discrepancy.

Benefits of Custom Shoe Lifts

• Non-invasive and affordable

• Improve alignment and walking comfort

• Help reduce stress on the hips, knees, and back

• Can be worn in everyday shoes

• Available as internal heel lifts or external shoe lifts, depending on the height needed

At Lilburn Shoe-Buddy, we handcraft each lift to match the exact height required, helping patients stay active and comfortable without surgery.

Surgical Options for Leg Length Discrepancy

In more severe cases, surgery may be considered. These procedures generally fall into two categories:

Bone-Shortening Surgery

This procedure reduces the length of the longer leg to better match the shorter one.

Bone-Lengthening Surgery

This procedure gradually increases the length of the shorter leg.

While surgery can be effective, it involves significant risks, extended recovery time, and high costs. Possible complications include infection, bleeding, pain, improper bone healing, and over- or under-correction.

Cost Considerations

Surgical correction of a leg length discrepancy can cost tens of thousands of dollars and usually requires hospitalization and physical therapy. Insurance coverage varies and should always be verified in advance.

By comparison, custom shoe lifts typically range from $50 to $200+, depending on the height and whether the lift is internal or external—making them a cost-effective option for many patients.
