The AKSS-F, AKSS-O and Tegner score were recorded from patients
MAD mechanical axis deviation, MPTA medial proximal tibial angle, LDFA lateral distal femur angle, LLD Leg length discrepancy, HKA hip–knee–ankle angle, AKSS-F American Knee Society Functional Score, AKSS-O American Knee Society Objective Score; Paired samples t test was used
