  1. All parameter values are reported as mean (standard deviation)
  2. KVPA knee valgus physiologic angle, mMDFA mechanical medial distal femoral angle, HKA hip-knee-ankle angle
  3. *There were significant differences when comparing type 90° with types 45° (p1, p4, p7), 60° (p2, p5, p8), and 75° (p3, p6, p9) in terms of KVPA, mMDFA, and HKA, respectively
