Leg Length Discrepancy (LLD) Treatment in Delhi NCR

Expert Assessment, Custom Shoe Lifts & Orthotic Solutions

Leg Length Discrepancy (LLD), also known as unequal leg length or limb length inequality, is a condition in which one leg is shorter than the other. Even a small difference in leg length can affect the way you stand, walk, and move. Over time, this imbalance may place extra stress on the feet, knees, hips, pelvis, and spine, leading to pain and poor posture.

At Revamp Prosthetics & Orthotics, we provide comprehensive evaluation and personalized treatment for leg length discrepancy using advanced gait analysis, custom orthotic solutions, shoe modifications, and rehabilitation strategies. Our goal is to restore body alignment, reduce pain, and improve your walking efficiency.

What is Leg Length Discrepancy?

Leg Length Discrepancy (LLD) occurs when one lower limb is shorter than the other. The difference may involve the femur (thigh bone), tibia (shin bone), foot height, or a combination of these structures.

Many people have a very small difference in leg length that causes no symptoms. However, larger discrepancies can significantly affect posture, gait, joint loading, and overall mobility. LLD can affect both children and adults and may be present from birth or develop later due to injury or disease.

Types of Leg Length Discrepancy

Structural (Anatomical) Leg Length Discrepancy

Structural LLD occurs when there is an actual difference in bone length between the legs.

Common causes include:

Congenital limb differences
Growth plate injuries
Previous fractures
Bone infections
Hip disorders
Bone tumors
Developmental abnormalities
Previous orthopedic surgery

Functional Leg Length Discrepancy

In functional LLD, both legs are equal in bone length, but one leg functions as though it is shorter because of alignment or movement abnormalities.

Possible causes include:

Pelvic tilt
Muscle tightness
Hip contractures
Foot overpronation
Flat feet
Joint stiffness
Spinal alignment problems

Unlike structural LLD, functional discrepancies can often improve significantly with appropriate treatment.

Symptoms of Leg Length Discrepancy

Symptoms vary depending on the amount of discrepancy and how long it has been present.

Common symptoms include:

One shoulder or hip appearing higher
Uneven walking pattern (limping)
Pelvic tilt
Lower back pain
Hip, Knee or foot pain
Recurrent ankle injurie
Muscle fatigue
Poor balance
Difficulty running
Uneven shoe wear

Children may also develop abnormal posture or compensatory walking patterns as they grow.

Causes of Leg Length Discrepancy

Leg length differences may develop due to several conditions, including:

Congenital Causes

Fibular hemimelia
Congenital femoral deficiency
Developmental hip disorders
Hemihypertrophy
Skeletal dysplasia

Acquired Causes

Fractures
Bone infections (osteomyelitis)
Growth plate injuries
Arthritis
Previous joint replacement
Bone tumors
Neurological disorders
Cerebral palsy
Polio
Trauma

How Leg Length Discrepancy Affects the Body

Even a small difference in leg length can change the body’s biomechanics.

Possible long-term effects include:

Altered gait mechanics
Increased stress on knees and hips
Chronic lower back pain
Pelvic rotation
Functional scoliosis
Foot overpronation or oversupination
Muscle imbalance
Increased energy expenditure while walking
Reduced athletic performance

Proper assessment helps determine whether these symptoms are actually related to leg length difference or another underlying condition.

When Should You See a Specialist?

Consult a specialist if:

Knock knees persist after 7 years of age
Only one leg is affected
The deformity is worsening
Knee or hip pain develops
Walking becomes difficult
Frequent falls occur
The ankle gap exceeds approximately 8 cm
Adults develop knock knees later in life

Early assessment helps identify whether the condition is developmental or pathological.

Diagnosis of Leg Length Discrepancy

Accurate diagnosis is essential before beginning treatment.

Our assessment includes:

Clinical Examination

Medical history
Physical examination
Standing posture evaluation
Pelvic alignment assessment
Joint mobility assessment

Block Test

Blocks of different heights are placed beneath the shorter leg until the pelvis becomes level. This simple method helps estimate the amount of discrepancy.

Gait Analysis

Walking mechanics are evaluated to identify:

Limping
Compensatory movements
Foot alignment
Knee mechanics
Hip stability

Imaging (When Required)

If necessary, your doctor may recommend:

Standing long-leg X-rays
Scanography
Bone age assessment (for growing children)
CT scanography
EOS imaging

Leg Length Discrepancy Treatment at Revamp Prosthetics & Orthotics

Treatment depends on:

Amount of discrepancy
Age
Symptoms
Cause
Growth potential
Functional limitations

Our approach focuses on improving comfort, restoring alignment, and reducing abnormal joint stress.

Custom Shoe Lifts

For many patients, a custom shoe lift is the most effective conservative treatment.

Each lift is individually designed based on precise measurements.

Custom Orthotics

Custom foot orthoses help optimize lower limb biomechanics and improve weight distribution.

They are especially useful when leg length discrepancy is associated with:

Flat feet
Overpronation
High arches
Foot instability

Footwear Modification

Our specialists provide professional shoe modifications, including:

External sole build-ups
Heel lifts
Full-length shoe raises
Customized footwear adjustments

Gait Training

We help patients develop a more efficient walking pattern by correcting compensatory movements and improving lower limb alignment.

When is Surgery Needed?

Most mild to moderate leg length discrepancies can be managed conservatively.

Surgery may be considered when:

The discrepancy is significant.
Symptoms remain severe despite conservative treatment.
The difference continues to increase during growth.
Walking ability is significantly affected.

Depending on age and severity, surgical options may include:

Growth plate modulation (epiphysiodesis) in growing children
Limb lengthening procedures
Bone shortening procedures
Corrective osteotomy

Why Choose Revamp Prosthetics & Orthotics?

Comprehensive biomechanical assessment
Digital gait analysis
Custom shoe lifts
Precision orthotic fabrication
Footwear modification
Rehabilitation guidance
Long-term follow-up
Patient-centered treatment plans

Every solution is customized according to your individual anatomy, activity level, and lifestyle.

Frequently Asked Questions

Can a small leg length difference cause pain?

Yes. Even a relatively small discrepancy may contribute to back, hip, knee, or foot pain in some individuals, especially if combined with abnormal biomechanics.

Is leg length discrepancy common?

Yes. Mild differences in leg length are common and often cause no symptoms. Larger discrepancies are more likely to affect posture and walking.

Can orthotics correct leg length discrepancy?

Custom orthotics and shoe lifts can effectively compensate for many mild to moderate discrepancies, improving alignment and reducing pain. However, they do not permanently change bone length.

Will my child outgrow leg length discrepancy?

It depends on the underlying cause. Some differences remain stable, while others may increase as a child grows. Regular orthopedic evaluation is important.

Do I need surgery?

Not necessarily. Many patients achieve excellent results with conservative treatment. Surgery is generally reserved for larger discrepancies or cases causing significant functional limitations.
