Hip Replacement Leg‑Length Discrepancy: Malpractice Elements & Legal Steps

A leg‑length discrepancy (LLD) after total hip arthroplasty (THA) can be a recognized complication, but it may also reflect surgical error. Proving malpractice requires establishing four legal elements.

Required Elements of a Malpractice Claim

1. Duty of Care: Surgeon‑patient relationship existed; standard of care = what a reasonably competent orthopedic surgeon would do under similar circumstances.
2. Breach of Duty (Negligence): Deviation from standard. Examples:
   • Inaccurate preoperative templating
   • Improper component sizing/positioning
   • Failure to assess leg length intraoperatively (trial reduction, fluoroscopy, computer navigation)
   • Ignoring preoperative LLD or pelvic obliquity
3. Causation: The breach directly caused the LLD. Expert testimony typically needed to link surgical technique to outcome.
4. Damages: Measurable harm—chronic pain, gait abnormality, back/hip/knee pain, revision surgery costs, lost wages, diminished quality of life.

Important Nuances

• Acceptable LLD: ≤1 cm is often considered within normal postoperative variation; >1.5–2 cm more likely actionable.
• Intentional lengthening: Surgeons sometimes deliberately lengthen slightly to improve stability—documented in operative note.
• Statute of limitations: Varies by state (often 2–3 years from discovery).

Practical Steps

1. Obtain complete medical records (operative report, implant logs, imaging).
2. Consult a board‑certified orthopedic surgeon for independent review.
3. Engage a medical‑malpractice attorney experienced in orthopedic cases.
4. Preserve evidence; avoid altering records or communicating with defendants without counsel.
