Core Tip	Leg-length discrepancies (LLDs), often greater than 5-10 mm, may result in altered gait mechanics, low-back pain, or the perception of limb inequality. These issues can directly affect patient satisfaction and functional recovery. Several advanced methods have been developed to address LLD, including accelerometer-based portable navigation system, preoperative digital templating, robot-assisted surgery, the anatomical marker positioning method (shoulder-to-shoulder) and the artificial intelligence-based three-dimensional planning system. However, it is worth noting that no technique completely eliminates the possibility of post-surgical LLD. Complex deformities, intraoperative instability, and soft-tissue imbalances can still lead to measurable discrepancies, despite the utilization of advanced tools.
