Coronal axis deviations in medial unicompartmental knee arthroplasty failures: an imaging study of patients revised for aseptic loosening
Our cohort of patients revised from medial UKA to TKA for aseptic loosening frequently exhibited consistent deviations in lower limb alignment, particularly increased AMA and JLCA, and reduced mLDFA, mMPTA, and mLDTA. These subtle but recurrent patterns may alter load distribution across the medial compartment, contributing to implant micromotion and loosening. A detailed preoperative axis assessment may help identify patients at a higher biomechanical risk.
