What causes leg length difference? 

Leg length difference, also known as limb length discrepancy, occurs when you or your child has one leg shorter than the other. Some people are born with this condition, while others develop it as they grow.

Several factors can contribute to leg length difference, including:

• Congenital conditions present at birth
• Growth plate injuries that affect bone development
• Fractures that don’t heal correctly
• Bone infections
• Neuromuscular conditions
• Hip disorders or developmental abnormalities
• Certain genetic or skeletal conditions

In some cases, the difference is mild and remains stable. In others, the discrepancy may increase over time.

What symptoms can accompany a leg length difference? 

Common signs and symptoms include:

• Limping or an uneven gait
• Frequent tripping or difficulty with balance
• Standing with one hip higher than the other
• Uneven shoulders or posture
• Complaints of hip, knee, or back pain
• Fatigue during physical activity
• Uneven wear on shoes
• Favoring one leg

If these symptoms are present, schedule an evaluation with Dr. Cho.

Can leg length difference be addressed? 

Yes. Many cases of leg length difference can be successfully managed or corrected. For smaller differences, treatment may involve observation and regular follow-up appointments to monitor growth. In some cases, a shoe lift or orthotic device may improve balance and comfort.

For larger discrepancies, Dr. Cho can discuss surgical treatment. Depending on your or your child’s age, advanced orthopedic techniques can slow growth in the longer leg, stimulate growth in the shorter leg, or lengthen the affected limb for greater symmetry.

How is leg length difference treated? 

Treatment begins with a comprehensive evaluation that may include a physical examination, gait assessment, and imaging studies to measure the exact difference in leg length.

Dr. Cho will develop a personalized treatment plan based on current measurements and future growth projections. Depending on the treatment approach, the plan may include:

•  Undergoing routine monitoring
• Using a shoe lift
• Participating in physical therapy
• Receiving surgical care, when appropriate

With early diagnosis and expert orthopedic management, most children and adults with leg length difference can achieve improved alignment, better mobility, and an active lifestyle. 

Dr. Cho designs your treatment plan to not only address the current discrepancy but also to support long-term function and mobility. Call the office or request an appointment online today to learn more about the treatment options for leg length difference.
