Leg-Length Discrepancy After Total Hip Arthroplasty: Comparison of Robot-Assisted Posterior, Fluoroscopy-Guided Anterior, and Conventional Posterior Approaches.

Abstract: Total hip arthroplasty (THA) effectively provides adequate pain relief and good long-term outcomes in patients with hip osteoarthritis. However, leg-length discrepancy (LLD) remains the most common cause of patient dissatisfaction and malpractice litigation in hip arthroplasty. We conducted a study to compare LLD in patients who underwent THA performed with a robot-assisted posterior approach (RTHA), a fluoroscopy-guided anterior approach (ATHA), or a conventional posterior approach (PTHA). We reviewed all RTHA, ATHA, and PTHA cases performed by Dr. Domb between September 2008 and December 2012.
