Abbreviation: HKAA, hip–knee–ankle angle; KAA, knee alignment angle; LDFA, lateral distal femur angle; MPTA, medial proximal tibial angle. Data with normal distribution are presented as median (25th—75th percentile). Significant results are shown in bold. a There was one patient missing the post-op information of HKAA, KAA, LDFA, MPTA.
