Does limb length discrepancy cause limping?

When one leg is shorter, the pelvis may tilt and the body may compensate through the hip, knee, foot, or lower back. These adjustments can make the stride uneven, shorten the time spent on one side, or cause a person to lift a heel or swing a leg differently. A limp can also arise from pain, weakness, joint stiffness, or a temporary injury, so walking pattern alone cannot identify the cause. Some differences are present from childhood, while others follow a fracture, growth disturbance, joint replacement, or another change in the leg.

Arrange an assessment if the limp persists, is becoming more noticeable, or is accompanied by hip, knee, foot, or back discomfort. A clinician can observe your gait, compare leg length clinically, and decide whether imaging is useful. Treatment depends on the measured difference and its effect on function. Options may include shoe modification, targeted physiotherapy, strength and balance work, or treatment of another source of pain. Do not add a large lift without professional advice, because a sudden change can strain the walking pattern.

Seek urgent medical care after a fall or injury if you cannot bear weight, the leg looks deformed, or pain and swelling are severe. Prompt assessment is also appropriate for a new limp with fever, marked weakness, numbness, or loss of bladder or bowel control. For a gradual limp without these warning signs, book a routine musculoskeletal assessment so the cause and useful correction can be considered.

Could the difference be structural or caused by how I stand and walk? How will you measure it? Would a temporary shoe lift or physiotherapy be appropriate? What changes should make me return sooner?
