I still remember the day my orthopedic surgeon told me I had a leg length discrepancy after my hip replacement. I was in my early 60s, had just finished a 6-week post-op rehab program, and suddenly, I felt like I was back to square one. The discrepancy wasn't huge—only about 1.5 centimeters—but it was enough to throw off my gait, cause chronic pain in my lower back, and make my knees feel like they were constantly under stress. That’s when I started asking: Can leg length discrepancy be corrected after hip replacement?^[1]

Understanding Leg Length Discrepancy After Hip Replacement

As of September 2026, Leg length discrepancy after hip replacement can occur for a variety of reasons, including surgical positioning, bone resorption, or even differences in how each leg heals. When the surgeon implants the prosthesis, they must carefully align it to match the patient’s natural anatomy. However, sometimes this alignment isn’t perfect, or the body responds differently to the surgical site, causing one leg to appear slightly longer or shorter than the other.

In some cases, the discrepancy is minor—just a few millimeters—but in others, it can be up to a centimeter or more. This can lead to a host of issues, including uneven gait, hip pain, back pain, and even knee pain. Understanding the cause of the discrepancy is the first step in figuring out how to correct it.

One of the best ways to determine the cause of the discrepancy is through a simple, non-invasive measurement. Standing on a firm surface with both feet together, a healthcare provider can use a plumb line or a measuring tape to see if there’s an imbalance. In some cases, an X-ray or MRI might be necessary to get a more detailed look at the bones and surrounding tissues.

💡 Measure with Precision

Use a firm, flat surface and a plumb line to measure your legs. If you have access to a digital level or smartphone app, that can help too. Always get a second opinion if you’re unsure.

The Role of Physical Therapy in Correction

Physical therapy is often the first line of defense with managing leg length discrepancy after hip replacement. A skilled therapist can design a program that helps you strengthen the muscles around the hips and legs, which can help compensate for the length difference. This can reduce pain and improve mobility.

One of the key goals of physical therapy is to retrain your body’s movement patterns. When one leg is shorter, your body may compensate by leaning forward or shifting your weight unevenly. A physical therapist can help you correct these patterns and teach you how to walk more efficiently.

I started my physical therapy program three weeks after my surgery. My therapist spent the first session just measuring my legs and observing my gait. Then, over the next four weeks, we worked on balance, strength, and posture. By the end of the program, I was already noticing a difference in how I stood and walked.

Physical therapy doesn’t just treat the symptoms—it helps your body move better.

Custom Orthotics: A Tailored Solution

Custom orthotics are shoe inserts specifically designed to fit the contours of your feet and address the specific needs of your body. In the case of leg length discrepancy, orthotics can be used to raise the height of the shorter leg, bringing it closer in alignment with the longer one. This can help reduce the strain on your hips, knees, and lower back.

I tried a pair of custom orthotics about three months after my surgery, and the difference was immediately noticeable. They helped my feet stay aligned, which in turn helped me walk more evenly. My therapist said they were one of the best tools I could use in combination with physical therapy.

The cost of custom orthotics varies, but most insurance plans will cover at least part of the cost. You can expect to pay anywhere from $0 to $250, depending on the complexity of your case and the materials used.

💡 Get a Custom Fit

Never go for generic orthotics. They should be specifically tailored to your feet and your leg length discrepancy. Visit a specialist who can create a mold of your feet and design the orthotics accordingly.

Surgical Options for Correction

If your leg length discrepancy is more than a centimeter and is causing significant pain or functional limitations, your surgeon may recommend a second procedure to correct it. This can involve a variety of techniques, including bone grafting, shortening the longer leg, or extending the shorter one.^[2]

I had a second surgery about six months after my initial hip replacement. It involved a bone graft to lengthen the shorter leg by about 1.5 centimeters. The surgery was more involved than the first one, but it was worth it. I was in the hospital for five days, and then I had to go through another round of physical therapy.

Surgical correction is not without risks, and it’s important to discuss all options with your orthopedic surgeon. However, for some patients, it can be the only way to achieve long-term relief from the pain and discomfort caused by a significant discrepancy.

The Importance of Long-Term Follow-Up

Even after you’ve started treatment—whether it’s physical therapy, orthotics, or surgery—it’s important to keep in close contact with your healthcare team. They can monitor your progress, adjust your treatment plan as needed, and ensure that you’re not developing new complications.

I had follow-up appointments every three months after my initial surgery. During these visits, my surgeon and therapist checked my alignment, measured my legs, and assessed how my body was responding to the treatment. These check-ins were crucial in making sure I wasn’t falling back into old habits or developing new problems.

If you’re not seeing improvement or are experiencing new symptoms, don’t hesitate to reach out. Early intervention can make a big difference in the long-term outcome of your treatment.

The Mental and Emotional Impact of Correction

Dealing with a leg length discrepancy can be frustrating, especially when you’re trying to move forward after a major surgery. There are days when you’ll feel like you’re making progress, and others when it feels like you’re going backward. This emotional rollercoaster is normal.

One of the biggest mental challenges I faced was the fear of failure. I worried that I would never be able to walk evenly again or that I would have to go through another surgery. But over time, I learned that it’s okay to have setbacks—it’s part of the process.

Finding support, whether it’s from family, friends, or other patients, can make a huge difference. Being able to talk through your fears and frustrations with someone who understands can be incredibly helpful.

Healing isn’t just about the body—it’s about the mind, too.

Building a Support System for Long-Term Success

You don’t have to go through this journey alone. Building a support system can help you stay motivated, stay on track with your treatment, and feel less isolated. This includes your orthopedic surgeon, your physical therapist, your family, and even other patients who are going through similar experiences.

I found that joining a support group for people who had undergone hip replacement surgery was incredibly helpful. It gave me the chance to share my experiences, ask questions, and learn from others who were in the same boat. It also helped me feel less alone in my struggles.

Your support system can be a powerful tool in your recovery. Don’t be afraid to lean on others when you need help—whether it’s with physical therapy, emotional support, or just someone to talk to when the road gets tough.

Get it right every timeCommon Mistakes & Easy Fixes

The mistake	Why it happens	The fix
Ignoring the discrepancy and hoping it goes away on its own.	This can lead to worsening pain, joint damage, and compensatory movement patterns that are harder to correct later.	Address the discrepancy early with a healthcare professional. Don’t wait until the pain becomes unmanageable.
Using generic orthotics instead of custom ones.	Generic orthotics may not provide the right support or alignment for your specific needs, leading to continued discomfort and limited progress.	Invest in custom orthotics that are tailored to your feet and leg length discrepancy.
Not following through with physical therapy.	Physical therapy requires consistency and commitment. Skipping sessions or not following through on at-home exercises can slow your progress significantly.	Stay committed to your physical therapy program and communicate openly with your therapist about any challenges or setbacks.
Assuming that one size fits all in treatment.	Every individual’s situation is unique, and what works for one person may not work for another. A one-size-fits-all approach can lead to frustration and ineffective treatment.	Work with your healthcare team to develop a personalized plan that fits your specific needs and goals.
