Whether you have a legal claim depends on whether the surgeon's work fell below the standard of care

A leg length difference after hip replacement can happen even when a surgeon performs the procedure correctly. The question of whether you can sue turns on whether the surgeon made a mistake that caused the problem, or whether it resulted from the inherent limits of the surgery itself. You will need to show that the surgeon deviated from what a competent surgeon would have done in the same situation — not straightforward that you are unhappy with the outcome.

Leg length discrepancy is a known possible outcome of hip replacement. Surgeons aim to match your leg lengths during the procedure, but achieving perfect symmetry is difficult. Small differences (under half an inch) are common and often go unnoticed. Larger differences can cause pain, gait problems, and the need for a shoe lift. The question is whether your surgeon's actions or inactions created the problem negligently.

Key Takeaways

  • You can only sue if you can show the surgeon breached the standard of care — meaning they did something a competent surgeon would not have done, or failed to do something a competent surgeon would have done.
  • Leg length differences are a known risk of hip replacement surgery, and small discrepancies do not automatically mean negligence occurred.
  • You will need an orthopedic surgeon to review your medical records and testify that the surgeon's conduct fell below accepted standards.
  • Documenting your pre-surgery leg lengths, post-surgery measurements, and any symptoms you developed is essential to building a claim.
  • Most medical malpractice claims require you to file within a specific time window set by your state's statute of limitations, which typically ranges from one to three years.

What constitutes negligence in a hip replacement case

Medical negligence in surgery requires three elements: the surgeon owed you a duty of care (which they always do), they breached that duty by acting below the standard of care, and that breach caused you measurable harm. The standard of care means what a reasonably competent orthopedic surgeon would have done under the same circumstances — not what the best surgeon in the world would have done, and not what would have produced a perfect result.

In a leg length discrepancy case, negligence might exist if the surgeon failed to measure leg length before and after the procedure, failed to use standard techniques to restore length, or made an error in component positioning that directly caused the mismatch. It would not exist straightforward because the outcome was imperfect. Courts and juries understand that surgery has inherent limitations.

You will need an informed witness — another orthopedic surgeon — to review your records and testify about what the standard of care required. This informed must state, based on the medical evidence, that your surgeon's actions fell below what a competent surgeon would have done. Without this informed testimony, your case will be dismissed.

What medical records you need to gather

Start by obtaining your complete surgical file from the hospital and surgeon's office. Request pre-operative imaging (X-rays, CT scans), operative notes from the surgery itself, post-operative imaging, and all follow-up visit notes. The operative notes are critical — they document what the surgeon actually did during the procedure, what measurements were taken, and whether leg length was addressed.

Look for documentation of your leg lengths before surgery. If the surgeon did not measure or document pre-operative leg length, that itself may suggest a breach of standard care, since most surgeons photograph or measure legs before and after to verify their work. Post-operative imaging should show the position of the implant components, which affects leg length.

Gather any records from physical therapy, your primary care doctor, or other specialists who treated you after surgery. If you developed pain, limping, or other symptoms after the surgery that you did not have before, those records create a timeline showing the problem is connected to the surgery. Photographs of your gait or posture, and any shoe lifts or orthotics you had to purchase, are also useful evidence of the harm caused.

How to find an informed witness

You cannot pursue a medical malpractice claim without an orthopedic surgeon willing to review your case and provide an opinion. Start by contacting a medical malpractice attorney in your state — they have relationships with experts and can determine whether your case is worth pursuing before you invest time and money.

The informed must be a licensed orthopedic surgeon, ideally one with experience in hip replacement. They will charge a fee to review your records (typically $500 to $2,000 for an initial review) and provide a written opinion on whether the standard of care was breached. If the informed concludes the surgeon acted appropriately, your case will be difficult to pursue. If the informed agrees there was a breach, they will likely testify at trial if the case proceeds.

Many attorneys work on contingency in medical malpractice cases, meaning they take a percentage of any settlement or judgment rather than charging upfront fees. However, you will still be responsible for informed fees and court costs, which can total several thousand dollars even if you win.

Statute of limitations and filing important date

Every state has a statute of limitations that sets a important date for filing a medical malpractice lawsuit. These vary significantly by state. Some states give you one year from the date of surgery, others give you two or three years, and some allow longer if the injury was not discovered when ready. A few states have a "discovery rule" that starts the clock when you discover (or reasonably should have discovered) the injury, not when the surgery occurred.

You must file your lawsuit before the important date expires, or you lose the right to sue permanently. Some states also require you to file a notice of intent to sue or obtain a certificate of merit from an informed before filing the actual lawsuit. Do not delay — contact an attorney as soon as you suspect negligence, because the important date may be closer than you think.

What damages you might recover

If you win a medical malpractice case, damages typically include medical expenses related to treating the problem (such as revision surgery, physical therapy, or orthotics), lost wages if you missed work, and pain and suffering. The amount of pain and suffering damages varies widely by state and by the severity of your condition.

A small leg length difference that causes no symptoms and requires no treatment will be harder to win damages for than a significant discrepancy that required a second surgery or caused chronic pain. Courts want to see that the negligence caused real, measurable harm — not just an imperfect surgical outcome.

When revision surgery might be necessary

If the leg length discrepancy is large enough to cause pain, gait problems, or other functional issues, your surgeon may recommend revision surgery to correct it. This is a second major operation that carries its own risks. If negligence in the first surgery made revision necessary, the cost and pain of that second surgery strengthens your claim for damages.

Document everything related to the revision — the surgeon's notes explaining why it was needed, the operative report, and your recovery. This creates a clear chain showing that the first surgeon's error led directly to additional surgery and harm. Keep records of any time off work, physical therapy costs, and ongoing symptoms.

Frequently Asked Questions

Does a small leg length difference automatically mean the surgeon was negligent?

No. Small differences under half an inch are common after hip replacement and do not indicate negligence. You must show the surgeon deviated from the standard of care — meaning they did something a competent surgeon would not have done, or failed to do something they should have done. A perfect outcome is not the legal standard.

What if my surgeon did not measure my leg length before surgery?

That may support a negligence claim, because most surgeons document pre-operative leg length to verify their work afterward. Failure to measure could suggest the surgeon did not follow standard protocol. However, you will still need an informed to testify that this omission fell below the standard of care and caused your specific problem.

How much does it cost to pursue a medical malpractice lawsuit?

informed review fees typically range from $500 to $2,000 initially, and informed testimony at trial can cost $5,000 to $15,000 or more. Court filing fees, discovery costs, and other expenses add up. Many attorneys work on contingency, so you do not pay upfront, but you are responsible for costs if you lose. Discuss fees and costs with an attorney before proceeding.

How long do I have to file a lawsuit?

Your state's statute of limitations sets the important date — typically one to three years from surgery, though some states use a discovery rule that starts the clock when you discover the injury. The important date varies by state, so contact an attorney when ready to learn your important date. Missing it means losing your right to sue permanently.

Can I sue if I had a pre-existing leg length difference?

Yes, but you must show the surgeon made it worse. You will need pre-operative measurements or imaging showing your original leg lengths, and post-operative measurements showing the difference increased. The informed will compare what the surgeon did to what should have been done to correct or maintain your original leg lengths.
