Abstract

This article focuses on the impact of simulating hip length (HL) equalisation on leg-length difference (LLD) before and after total hip arthroplasty (THA) using computerized planning. In a study of 141 patients, preoperative LLD greater than 5 mm was found in 37.5% and greater than or equal to 10 mm in 14.8%. While HL equalisation reduced LLD in patients with shorter hips and preexisting LLD, it increased LLD beyond 5 mm in 40% and beyond 10 mm in 10% of patients who had no preoperative LLD. The findings suggest that restoring symmetrical hip morphology may not be appropriate for all patients, highlighting the need for individualized preoperative planning and personalized femoral stem positioning to optimize outcomes.
